In emergency services, the earliest possible hospital transport contributes to the improvement of the survival rate and the prognosis reintegration rate. In order to respond to emergency calls that may occur at any time, it would be ideal to distribute as many ambulance crews as possible evenly throughout the area. It is being considered to deploy them in areas where requests are likely to occur and to operate them efficiently. In the past, operators used experience to predict the number of dispatches and arrival times for each area, and then determine the deployment of ambulance crews.

In general, the deployment of ambulance crews, for example, the deployment of each day's crew, is planned in advance and is carried out according to the plan. In addition, although the number of dispatches and dispatch areas fluctuate due to various factors, correlated factors include the day of the week, time of day, season, population composition, weather conditions, and the like. In addition, in areas where the number of customers tends to increase or decrease due to customary events or annual events, it may be possible to predict the tendency of the number of dispatches to increase or decrease. On the other hand, in recent years, Halloween events without organizers have spontaneously occurred locally through the Internet and SNS (social networking services). In some cases, it increases to

Therefore, in the first embodiment according to the present invention, a deployment support system that outputs simulation results to support the determination of the deployment of ambulance crews based on statistically predictable population increases and decreases according to the date, day of the week, and weather. come true.

[First Embodiment] FIG. 1 is a diagram showing a configuration example of a placement support system according to the first embodiment. The placement support system includes a placement support device 101 . The placement support device 101 is a so-called information processing device such as a personal computer, a smart phone, a tablet terminal, or a server device. The placement support apparatus 101 includes an input reception unit 102 that receives instructions from the operator through mouse operation, touch panel operation, or the like, a display unit 103 that presents a screen to the operator, a storage unit 104 that holds various information, and a processing unit. and a portion 105 are included. The processing unit 105 controls various kinds of arithmetic processing and operations of the input receiving unit 102 , the display unit 103 , and the storage unit 104 . The input reception unit 102, the display unit 103, the storage unit 104, and the processing unit 105 are connected by a common bus (including a data bus and an address bus).

The deployment support system is used, for example, at the start of ambulance services to determine the deployment of teams for the day or several days.

The input reception unit 102 receives input information from the operator via the user interface. The display unit 103 outputs information to the operator through the user interface.

Storage unit 104 includes calendar information 1041 , map information 1042 , population information 1043 , weather information 1044 , and troop placement information 1045 .

FIG. 2 is a diagram showing an example of the data structure of calendar information. Calendar information 1041 is associated with days of the week 1041B and holidays 1041C according to dates 1041A. The date 1041A is information specifying the date, and is indicated in a predetermined format such as YYYY/MM/DD. The day of the week 1041B is information specifying the day of the week, and is indicated in a predetermined format such as "Sun" or "Mon". The holiday 1041C is information specifying whether the day falls under a holiday.

The map information 1042 is map information including landform information, and the latitude and longitude of an arbitrary point on the landform expressed in a predetermined format (not shown), the landform information of the point, the address information of the point, etc. are associated with each other. It is The map information 1042 also includes information specifying road connections, and information on travel costs (time, distance, tolls, etc.) for traveling by vehicle. It should be noted that the map information 1042 is associated with information demarcated by a predetermined range (mesh), which will be described later.

FIG. 3 is a diagram showing an example of the data structure of population information. Population information 1043 is associated with population 1043C according to a combination of mesh ID 1043A and day of the week 1043B. The mesh ID 1043A is information specifying a mesh that is a range obtained by dividing a predetermined area or geographical range according to a predetermined rule. For example, meshes include standard regional meshes used for administrative municipalities and statistics, and tertiary meshes of about 1 km (kilometer) square. The position of the mesh on the map is determined by the latitude and longitude of the Japanese Industrial Standards in Japan, so this is used. In this embodiment, the tertiary mesh is used, but the present invention is not limited to this, and a standard regional mesh may be used. Population 1043C stores the actual population value (eg, average value over multiple years) for the day of the week identified by day of the week 1043B for the mesh identified by mesh ID 1043A. Since the daytime population also varies depending on the time of day, it may be possible to finely store the combination of the mesh, the day of the week, and the time of day. On the other hand, when the nighttime population is used, there is little variation depending on the day of the week and the time of day.

FIG. 4 is a diagram showing an example of the data structure of weather information. The weather information 1044 is associated with an area 1044A, date and time 1044B, and weather 1044C. The area 1044A is information specifying the minimum unit of area segment targeted in the weather information. The date and time 1044B is information specifying the minimum unit of date and time divisions targeted in the weather information. The weather 1044C stores weather forecasts (eg, sunny, cloudy, rainy, snowy, etc.) for the date and time specified by the date and time 1044B for the area specified by the area 1044A. Note that the forecast for the weather 1044C is not limited to such classification, and may include various weather information (various warnings and warnings, temperature, humidity, amount of precipitation, etc.).

FIG. 5 is a diagram showing an example of the data structure of troop placement information. Team placement information 1045 is associated with a team ID 1045B identifying an ambulance team and a deployment mesh ID 1045C identifying a mesh to which the ambulance team identified by the team ID 1045B is deployed for each time slot 1045A. The time zone 1045A is information specifying the time zone during which the ambulance crew is maintained.

In this embodiment, the calendar information 1041, the map information 1042, the population information 1043, the weather information 1044, and the unit placement information 1045 are created in advance by the operator and stored in the storage unit 104. However, the information is not limited to this, and information may be appropriately acquired from another system or the like and stored in the storage unit 104 .

The processing unit 105 includes an arrangement condition setting unit 1051 , a dispatch number calculation unit 1052 , an arrival time calculation unit 1053 , and an output screen generation unit 1054 .

The placement condition setting unit 1051 accepts input of a squad placement plan from the operator via the input reception unit 102 and stores it in the storage unit 104 as the squad placement information 1045 . For example, when the display unit 103 outputs a screen that superimposes mesh partitions on the target area, the arrangement condition setting unit 1051 accepts that an icon or the like indicating an ambulance team has been dropped on one of the meshes, It is stored in the troop placement information 1045 . Then, the deployment condition setting unit 1051 causes the display unit 103 to output a pop-up screen or the like for accepting input of information on the deployment time zone for the ambulance team, receives the input of the information on the deployment time zone, and stores it in the team deployment information 1045. do. In other words, the placement condition setting unit 1051 enables the input of the plan of the placement position of the squad through screen input.

The number of dispatches calculation unit 1052 calculates the number of dispatches based on the population and weather for each mesh for each time zone of the current day or a predetermined range of multiple days (for example, one week) in all meshes of the target area under the accepted troop deployment conditions. Perform processing to calculate the number of dispatches.

The number-of-dispatches calculation unit 1052 reads from the storage unit 104 various types of information that serve as conditions for calculation. For example, the dispatch number calculation unit 1052 acquires from the calendar information 1041 the day of the week of the relevant time zone on the current day, and from the population information 1043 the population of the relevant mesh on the relevant time zone on the current day. In addition, the number of dispatches calculation unit 1052 acquires the weather including the weather, temperature, and amount of rainfall in the relevant time zone on the day from the weather information 1044 . As a method for calculating the number of dispatches, the dispatch number calculation unit 1052 prepares in advance a multiple regression model for predicting the number of dispatches using the day of the week, population, and weather information as explanatory variables, and uses the model to calculate the number of dispatches in each time zone. get In addition to multiple regression models, we have adopted a method to predict the number of dispatches using various types of AI (artificial intelligence) such as regression trees, support vector machines, and various neural networks that have been trained using deep learning. may

The arrival time calculation unit 1053 calculates dispatches that occur in surrounding meshes for each mesh for each time zone of the current day or a predetermined range of multiple days (for example, one week) in all meshes of the target area under the conditions of the accepted team deployment. Add the number of cases and calculate the arrival time of each ambulance crew in the mesh based on population and weather. Since the number of ambulance crews is limited, if there are more dispatch requests than the number of ambulance crews in the same time zone, including the surrounding meshes, the later the dispatch request, the longer the arrival time to the site. It happens during operation. This is because it is desirable to reproduce such events in this system and calculate the arrival time at the site more accurately. Specifically, the arrival time calculation unit 1053 counts the number of dispatches of the meshes around the target mesh for each target mesh, and determines the number of dispatches of the target mesh. The range of the surrounding mesh is 8 neighboring neighborhoods (north, northeast, east, southeast, south, southwest, west, northwest), but 24 neighborhoods including the outside thereof may be used as the surrounding mesh.

Then, the arrival time calculation unit 1053 uses the number of dispatches of the mesh of interest to read out various kinds of information serving as conditions for calculation from the storage unit 104 . For example, the arrival time calculation unit 1053 acquires the day of the week in the time zone of the current day from the calendar information 1041 and the population of the mesh in the time zone of the current day from the population information 1043 . In addition, the arrival time calculation unit 1053 acquires the weather including the weather, temperature, and amount of rainfall in the time zone of the current day from the weather information 1044 . The arrival time calculation unit 1053 prepares in advance a multiple regression model for predicting the arrival time at the site using the day of the week, population, and weather information as explanatory variables as a method of calculating the arrival time at the site, and uses the model to calculate the arrival time at each time zone. Get the on-site arrival time for each dispatch. In addition to multiple regression models, various AI (artificial intelligence), such as regression trees, support vector machines, and various neural networks that have been trained using deep learning, etc., are used to predict the arrival time at the site. You may

The output screen generation unit 1054 generates a screen that displays the calculation result of the arrival time of the ambulance crew to the site. Specifically, the output screen generation unit 1054 displays the site arrival time corresponding to the site arrival time calculation result for each target mesh. Various methods are conceivable for this display method. perform highlighting. Moreover, the output screen generation unit 1054 may display the magnitude of the value of the on-site arrival time for all the meshes by the difference in color shade or hue. In addition, the output screen generation unit 1054 may generate a screen that displays the average value of on-site arrival times for the entire target area (mesh) and the number of dispatches.

FIG. 6 is a diagram illustrating a hardware configuration example of the placement support apparatus. The placement support device 101 is realized by the information processing device 900 . The information processing apparatus 900 includes a CPU (Central Processing Unit) 901, a memory 902, a hard disk drive (HDD), an external storage device 903 such as an SSD (Solid State Drive), and a CD (Compact).

The display unit 103 can be realized by the CPU 901 using the output device 907, and the storage unit 104 can be realized by the CPU 901 using the memory 902 or the external storage device 903. be.

This predetermined program is downloaded from the storage medium 904 via the read/write device 905 or from the network via the communication device 908 to the external storage device 903, then loaded onto the memory 902 and executed by the CPU 901. may be made.

Alternatively, it may be directly loaded into the memory 902 from the storage medium 904 via the read/write device 905 or from the network via the communication device 908 and executed by the CPU 901 .

Note that the example of the information processing apparatus 900 described above is an example of what can be realized by a general computer, and the present invention is not limited to this, and any information processing apparatus having a similar hardware configuration may be used.

FIG. 7 is a diagram showing an example of an input screen for squad arrangement information. On the screen 202 for inputting information on troop placement, a map 201 of the target area and a grid pattern showing a tertiary mesh (reference area mesh, latitude interval of 30 seconds, longitude interval of 45 seconds) that divides the area on the map into predetermined areas are displayed. line and an icon 203 indicating the location where the ambulance crew is to be deployed. By moving the icon 203 of the ambulance crew to an arbitrary mesh on this screen, the operator can perform input specifying the ambulance crew and the mesh to which the ambulance crew is arranged.

FIG. 8 is a diagram illustrating an example of the flow of placement simulation processing. The placement simulation process is started when the placement support apparatus 101 is started by the operator.

First, the placement condition setting unit 1051 receives conditions for platoon placement (step S001). Specifically, the deployment condition setting unit 1051 accepts the input of the team deployment conditions (emergency crew, deployment mesh of the emergency crew, deployment time zone) on the screen shown in FIG. Store in information 1045 .

Then, the dispatch number calculation unit 1052 sets the time zone and the place (attention mesh) (step S002). Specifically, the dispatch number calculation unit 1052 identifies combinations of meshes and time slots for which the number of dispatches has not yet been calculated.

Then, the dispatch number calculation unit 1052 reads out information related to the calculation of the number of dispatches (step S003). Specifically, the dispatch number calculation unit 1052 acquires the day of the week in the time zone of the current day from the calendar information 1041 and the population of the mesh in the time zone of the current day from the population information 1043 . In addition, the number of dispatches calculation unit 1052 acquires the weather including the weather, temperature, and amount of rainfall in the relevant time zone on the day from the weather information 1044 .

Then, the dispatch number calculation unit 1052 calculates the dispatch number (step S004). Specifically, the dispatch number calculation unit 1052 calculates the on-site arrival time of each ambulance crew in the mesh as described above for the time zone of the target mesh under the received team deployment conditions.

Then, the dispatch number calculation unit 1052 determines whether or not the calculation has been completed for all locations (step S005). Specifically, the number of dispatches calculation unit 1052 determines whether or not the combination of the mesh for which the number of dispatches has not yet been calculated and the time slot is within the target area and the target date and time range. If not, the calculation is completed for all places. ("Yes" in step S005). If the combination of the mesh for which the number of dispatches has not yet been calculated and the time period is within the range of the target area and the target date and time, the dispatch number calculation unit 1052 has not completed calculation for all locations ("No" in step S005). ), and the control returns to step S002.

When the calculation has been completed for all locations ("Yes" in step S005), the arrival time calculation unit 1053 calculates the number of dispatches in the vicinity (step S006). Specifically, the arrival time calculation unit 1053 regards a combination of each mesh and each time slot as a mesh of interest, and adds the number of dispatches occurring in eight neighboring meshes in the same time slot to determine the number of dispatches of the mesh of interest.

Then, the arrival time calculation unit 1053 sets the time zone and the place (attention mesh) (step S007). Specifically, the arrival time calculation unit 1053 identifies combinations of meshes and time slots for which arrival times at the site have not yet been calculated.

Then, the arrival time calculation unit 1053 reads out information related to calculation of arrival time at the site (step S008). Specifically, the arrival time calculation unit 1053 uses the number of dispatches of the target mesh to read out various types of information serving as conditions for calculation from the storage unit 104 . For example, the arrival time calculation unit 1053 acquires the day of the week in the time zone of the current day from the calendar information 1041 and the population of the mesh in the time zone of the current day from the population information 1043 . In addition, the arrival time calculation unit 1053 acquires the weather including the weather, temperature, and amount of rainfall in the time zone of the current day from the weather information 1044 .

Then, the arrival time calculation unit 1053 calculates the site arrival time for the mesh of interest (step S009). Specifically, the arrival time calculation unit 1053 uses a multiple regression model that predicts the arrival time at the site using the day of the week, population, and weather information created in advance as explanatory variables to obtain the arrival time at the site for each dispatch in each time zone. .

Then, the arrival time calculation unit 1053 determines whether or not the calculation has been completed for all locations (target meshes) (step S010). Specifically, the arrival time calculation unit 1053 determines whether or not the combination of the mesh for which the arrival time at the site has not yet been calculated and the time zone is within the target area and the target date and time range. If not, the calculation is completed for all locations. ("Yes" in step S010). If the combination of meshes and time slots for which the on-site arrival time has not been calculated remains within the target area and the target date and time range, the arrival time calculation unit 1053 has not completed calculation for all locations (" No”), and the control returns to step S007.

When the calculation is completed for all locations ("Yes" in step S010), the output screen generation unit 1054 displays the site arrival time (step S011). Specifically, the output screen generation unit 1054 generates a simulation result output screen, which will be described later, and causes the display unit 103 to display it.

The above is the flow of the placement simulation processing. According to the arrangement simulation process, it is possible to more accurately calculate the number of dispatches and the arrival time at the site.

FIG. 9 is a diagram showing an example of a simulation result output screen. The simulation result output screen is a screen for displaying the simulation calculation result of the arrival time of the ambulance crew to the site. Specifically, the output screen generation unit 1054 displays the site arrival time corresponding to the site arrival time calculation result for each mesh of interest superimposed on the map information with a delimiter. In FIG. 9, among the target meshes, those meshes whose arrival time on site calculation results are larger than a predetermined threshold value are highlighted 401 on the map, and an average value 402 of the arrival time on site for the entire target region is displayed. , and the dispatch number 403 are displayed.

The above is the placement support system and the placement support device according to the first embodiment. According to the deployment support system and the deployment support device according to the first embodiment, it is possible to more accurately calculate the number of dispatches and the arrival time at the site, and based on this, optimize the deployment of the actual team. It is possible to shorten the arrival time at the site.

[Second Embodiment] In the first embodiment, an example in which the operator manually creates the population information 1043 and the weather information 1044 held in the storage unit 104 has been described. The information may be automatically obtained from a provided external website or the like and held. It is sufficient to update the information about once a day, but the setting may be changed by the operator so that the information can be updated more finely, such as once an hour.

FIG. 10 is a diagram showing a configuration example of a placement support system according to the second embodiment. The placement support system according to the second embodiment is basically substantially the same as the placement support system according to the first embodiment, but a part of the placement support device 101' is different. The following description will focus on the differences.

A communication unit 106 is provided in the placement support apparatus 101' in the second embodiment. The communication unit 106 is communicably connected to the external weather information providing server device 10 via a network 50 such as the Internet from a communication device 908 using HTTP (HyperText Transfer Protocol) or the like. The weather information providing server device 10 is a device that provides so-called weather information for a limited area and time. The placement support device 101 ′ acquires the actual values of weather information up to the previous day and the preliminary values of the current day from the weather information providing server device 10 .

For example, in the case of Tokyo, meteorological data obtained from 10 observation stations, excluding islands, can be obtained. One observatory does not correspond.

FIG. 11 is a diagram showing an example of the layout display screen of the weather observation areas displayed by the display unit 103. As shown in FIG. Observation stations 601 exist less than the number of tertiary meshes, and there are meshes to which observation stations are directly assigned and meshes that are not directly assigned, that is, it is necessary to determine the observation stations to be assigned. Also includes meshes with Therefore, it is conceivable to calculate in advance the straight line distance between the latitude and longitude of the observatory and the center latitude and longitude of each mesh, and assign the observatory with the shortest distance to each mesh. Label 602 is a screen display showing the assignment of stations AD for each mesh. For example, a mesh labeled "A" indicates that the weather data for station A is reflected. By changing the label 602 on the weather observation area layout display screen, the operator can specify the observatory to be reflected in the mesh.

The above is the second embodiment. According to the second embodiment, by predetermining the correspondence between the observation stations and the meshes in this manner, the weather information 1044 automatically acquired in advance and held in the storage unit 104 is used for the arrangement simulation process. This makes it possible to calculate the site arrival time more simply.

[Third Embodiment] The number of dispatches may increase rapidly at times and places where events such as festivals and concerts are held where people gather. Therefore, in the third embodiment, by registering known irregular or regular event information in advance, the calculation result of the number of dispatches is corrected, and the on-site arrival time is calculated more accurately. An event is an event that has a scale in which the population in a predetermined range increases or decreases by a predetermined amount or more.

The date and time of the event, the venue, the number of participants, the stratum of participants, whether it is indoors or outdoors, the type of participation (whether the participants actually work or the viewing type), and whether or not the participants can drink alcohol. It is empirically known that the number of dispatches of ambulance crews fluctuates greatly depending on the situation. By receiving such event attribute information, the dispatch number calculation unit 1052 can change and correct the number of dispatches for the corresponding mesh of the event to some extent.

FIG. 12 is a diagram showing an example of an event registration screen in the third embodiment. The event registration screen includes an event name 701, date 702, time 703 (start time and end time), latitude and longitude 704 (coordinates) of the venue, expected number of participants 705, participant stratum 706, and venue 707. , Participation form 708 , and whether or not to drink alcohol 709 . The participant group 706 selectively accepts input of the age group of the main participants of the event, such as "young people", "families", and "elderly people". A holding facility 707 is an item for receiving an input specifying whether the holding facility of the event is indoors or outdoors. Indoor events such as concerts and outdoor events such as festivals and fireworks displays can be specified. Participation form 708 is a specification input as to whether it is a participation type, such as Halloween, in which the participants take the lead in activities, or an appreciation type, such as watching a sports game or a play, in which the participants are basically just watching. accept. Whether or not to drink alcohol 709 accepts a specified input as to whether or not the participant is allowed to drink alcohol. A register button 710 completes event registration when pressed. The registered event is held in an area (not shown) of storage unit 104 . Further, when a cancel button 711 is pressed, event registration is canceled.

FIG. 13 is a diagram illustrating an example of the flow of placement simulation processing (event variation). The placement simulation processing (event variation) according to the third embodiment is basically the same as the placement simulation processing flow described in the first embodiment, but there are some differences. The following description will focus on the differences.

In the placement simulation process (event change), a processing step S101 is added to correct the number of dispatches according to the event after the calculation of the number of dispatches is completed in step S005. The number of dispatches calculation unit 1052 extracts events to be held on the date and time period to be calculated from the events registered on the event registration screen shown in FIG. 12 . The turnout number calculation unit 1052 identifies a mesh to which the extracted latitude and longitude 704 of the venue of the event belongs, and corrects the turnout number of the mesh (step S101).

A method of correcting the number of dispatches when an event is held in step S101 will be described. The number of dispatches calculation unit 1052 obtains in advance a regression formula for the multiplier of the number of dispatches by the number of participants based on the past results, obtains the multiplier for the number of participants 705 of the registered event information, and multiplies the calculation result of the number of dispatches. do. As for the regression formula, it is desirable to prepare a formula having different coefficients for each combination of participant stratum 706 , venue 707 , participation mode 708 , and alcohol consumption 709 . Although the explanation is given here using the magnification of the number of dispatches, the number of cases that increases according to the number of participants may be used.

Also, the number of participants 705, participant stratum 706, venue 707, participation form 708, and whether or not to drink alcohol 709 may be used as explanatory variables to predict the number of dispatches themselves by multiple regression, a neural network, or the like.

Also, the range of meshes to be corrected is one mesh to which the latitude and longitude 704 of the venue belongs, but the correction may be applied to adjacent 8 neighboring meshes or 24 neighboring meshes including the outside thereof. Also, if the input of the holding facility 707 is "indoor", only the relevant mesh is corrected, and if it is "outdoor", 24 neighboring meshes are used. good. Furthermore, the correction may be applied more appropriately by having the operator input the mesh range to which the correction is to be applied on the event registration screen or the like.

The above is the placement support system and the placement support device according to the third embodiment. According to the placement support system and the placement support device according to the third embodiment, by registering known irregular or regular events in advance, the calculation result of the number of dispatches is corrected, and more accurately. It is possible to shorten the actual arrival time to the site by calculating the time to arrive at the site and optimizing the deployment of the team based on it.

[Fourth Embodiment] In the first to third embodiments, the on-site arrival time is calculated on the condition of the deployment of the team designated by the operator. However, the present invention is not limited to this, and troop placement may be optimized to present the troop placement that minimizes the time required to arrive at the site.

The fourth embodiment is basically the same as the first embodiment, but there are some differences. The difference will be mainly described below.

FIG. 14 is a diagram showing an example of the flow of squad placement efficiency improvement processing in the fourth embodiment. The troop placement efficiency process is started after the placement simulation process or the placement simulation process (event variation) is performed.

First, the deployment condition setting unit 1051 accepts designation of an ambulance team to be optimized (step S201). Specifically, the arrangement condition setting unit 1051 accepts the input of the ambulance team to be optimized on the screen shown in FIG.

After that, for the ambulance crews to be optimized received in step S201, the arrangement is changed in various meshes and time slots, the on-site arrival times are calculated and compared, and processing for specifying the optimum arrangement is performed.

The arrival time calculation unit 1053 arranges the target team on the mesh (step S202). Specifically, the arrival time calculation unit 1053 specifies the time zone and location (mesh of interest) where the ambulance team is to be arranged to be optimized as one of the combinations of the mesh and time zone for which the on-site arrival time has not yet been calculated. .

Then, the arrival time calculation unit 1053 calculates the on-site arrival time for all combinations of meshes and time slots, using the target mesh of the ambulance team to be optimized as a fixed condition (step S203). Specifically, the arrival time calculation unit 1053 uses a multiple regression model that predicts the arrival time at the site using the day of the week, population, and weather information created in advance as explanatory variables to obtain the arrival time at the site for each dispatch in each time zone. .

Then, the arrival time calculator 1053 calculates the average value for the entire target area (step S204). The average value is held in an area (not shown) of the storage unit 104 .

Then, the arrival time calculation unit 1053 determines whether or not the calculation has been completed for the case where the ambulance crews to be optimized are arranged at all locations (attention meshes) (step S205). Specifically, the arrival time calculation unit 1053 determines whether or not a combination of a mesh and a time zone for which the on-site arrival time has not been calculated for the ambulance team to be optimized remains within the target area and target date and time range. It is determined that the calculation has been completed for all locations ("Yes" in step S205). If the combination of the mesh for which the on-site arrival time has not been calculated and the time period is within the target area and the target date and time range, the arrival time calculation unit 1053 has not completed calculation for all places ("No" in step S205). ”), and the control returns to step S202.

When the calculation is completed for all locations (“Yes” in step S205), the output screen generation unit 1054 identifies the case where the average arrival time at the site is the minimum as the optimal arrangement of ambulance crews to be optimized. and presents the platoon arrangement (step S206). Specifically, the output screen generation unit 1054 generates a simulation result output screen shown in FIG. 9 and causes the display unit 103 to display it.

The above is the flow of the team placement efficiency improvement process. In the troop placement efficiency processing, for one of the troop, it is possible to calculate the site arrival time by changing the mesh to be deployed, the time zone, or both, and present the troop placement when the site arrival time is the minimum. can. According to the troop placement efficiency processing, it becomes possible to more accurately calculate the optimum arrival time at the site and the troop placement at that time.

The above is the placement support system and the placement support device according to the fourth embodiment. According to the deployment support system and the deployment support device according to the fourth embodiment, the average value of the on-site arrival time is minimized, that is, it is possible to calculate the optimized deployment of emergency crews, and the actual on-site It is possible to shorten the arrival time.

In the fourth embodiment, only one ambulance team is specified in step S201, but two or more teams, or even all teams can be designated as the ambulance team to be optimized. . In addition, it is also possible for the operator to specify the range in which ambulance crews can be deployed for optimization. During actual operation, it may be difficult to relocate specific ambulance crews to distant locations.

In addition, although the average value of arrival times at the site is used as an index for determining the optimum deployment of the team, the operator may change the index according to the viewpoint of importance, such as the maximum value or the median value. Furthermore, the operator may be allowed to specify the time span or the range of the target area for calculating the index such as the average value.
