2. Operation 2-1. Outline of Operation An outline of the operation of the elevator group management system according to the present embodiment will be described. The present system accepts registration of a user's destination floor by the destination floor registration device 30. When registration is received by the destination floor registration device 30, the destination floor call related to the registered destination floor is assigned to any of the plurality of elevators 60A to 60C in the group management control device 10. Further, in the elevator control device 40, operation control is performed such that the assigned car to which the registered destination floor is allocated is caused to travel from the registered floor (departure floor) where the destination floor is registered to the registered destination floor. . In addition, the destination floor registration device 30 that has received the registration acquires the assigned number information indicating the assigned number from the group management control device 10 and displays the information indicating the assigned number.

2-2. Operation of Group Management Control Device The operation of the group management control device 10 will be described with reference to FIG. The group management control device 10 performs an elevator assignment process by the control unit 11. The elevator assignment process is a process of assigning the destination floor registered by the destination floor registration device 30 to any one of the elevators 60A to 60C. Specifically, when receiving the assignment request signal from the destination floor registration device 30 via the input / output interface 13, the control unit 11 starts the elevator assignment process. The assignment request signal is a signal requesting that the destination floor registered by the destination floor registration device 30 be allocated to any one of the elevators 60A to 60C. The assignment request signal includes destination floor information indicating the destination floor registered by the user, departure floor information indicating the floor (departure floor) at which the registration operation of the destination floor was performed, and registration of the destination floor. Device identification information for identifying the entered destination floor registration device 30. The information indicated by the assignment request signal is hereinafter referred to as “assignment request information” as appropriate. The control unit 11 determines the departure floor and the destination floor indicated by the allocation request information in any of the elevators 60A to 60C, and evaluates the evaluation value E [c] described later for each of the elevators 60A to 60C (1st to 3rd units). Assign based on.

  Specifically, the control unit 11 acquires operation information of each elevator 60. The operation information of each of the elevators 60A to 60C (the first to third units) includes, for example, information indicating a car state (including a car position, a traveling direction, a door open / close state, a load, and the like) of each of the elevators 60A to 60C. The control unit 11 obtains values of a plurality of parameters, which will be described later, for each of the elevators 60A to 60C based on the operation information and the like of each elevator 60. Further, the control unit 11 calculates an evaluation value E [c] for selecting an elevator to which a destination floor is to be assigned, for each of the elevators 60A to 60C based on a plurality of parameter values. Here, the operation information of each of the elevators 60A to 60C includes, for example, a car state (including a car position, a traveling direction, a door open / close state, a load, and the like) of each of the elevators 60A to 60C.

  The plurality of parameters used when calculating the evaluation value E [c] include, for example, a predicted waiting time total value sum_wt [c], a predicted riding time total value sum_bt [c], and a predicted waiting time maximum value max_wt [c]. Etc. The predicted waiting time total value sum_wt [c] is the total value of the predicted waiting time wt [p] of all the users (including the temporary allocation) assigned to the car No. c. The predicted waiting time wt [p] is the time from when the assignment request signal is received until the assigned car arrives at the departure floor. In the calculation of these parameters, when the assigned car No. c arrives at the departure floor of the destination floor call, the assignment to car No. c is completed and deleted. That is, "assigned to the car No. c" means that the car No. assigned to the car has not yet arrived at the departure floor of the destination floor call. The predicted ride time total value sum_bt [c] is the total value of the predicted ride time bt [p] of all users assigned to the car c (including the temporary assignment). The predicted riding time bt [p] is the riding time of the user from the departure floor to the destination floor. The predicted waiting time maximum value max_wt [c] is the predicted waiting time having the largest value among the predicted waiting times wt [p] of all the users (including the temporary assignment) allocated to the car No. c. In this embodiment, when calculating the predicted waiting time maximum value max_wt [c], among the predicted waiting times wt [p] of all the users, the predicted floor of the user whose departure floor is a floor whose allocation cannot be changed is predicted. Only the waiting time wt [p] is targeted. Therefore, the predicted waiting time maximum value max_wt [c] is the maximum value of the predicted waiting time wt [p] of the user whose departure floor is the floor whose assignment cannot be changed among all the users.

  After calculating the evaluation value E [c], the control unit 11 selects the elevator having the smallest evaluation value E [c] among the plurality of elevators 60A to 60C, and sends a new destination floor call to the selected elevator. assign.

  The control unit 11 outputs a control signal for instructing the elevator control device 40 corresponding to the assigned elevator 60 (assigned car) to travel from the departure floor to the destination floor of the assigned new destination floor call.

  The control unit 11 outputs a signal for displaying the destination floor of the elevator 60 to the destination floor indicator 120 provided corresponding to each elevator 60 on the specific floor based on the assignment result.

  When the predicted waiting time wt [p] of a certain user (destination floor call) becomes larger than a predetermined value (for example, 90 seconds) after the assignment of the destination floor call, the control unit 11 determines the assigned destination floor call. A process of changing the assignment to another elevator is performed. When the control unit 11 changes the allocation, the destination floor indicator 120 corresponding to the elevator 60 of the allocation change source among the destination floor indicators 120 provided in association with the respective elevators 60 on the specific floor, the control unit 11 changes the destination of the elevator 60 to the specific floor. The signal for displaying the destination floor change is output.

  FIG. 6 is a diagram illustrating an elevator hall on a specific floor in a building to which the elevator system according to the first embodiment is applied (a diagram illustrating a state in which an assignment change is displayed on a destination floor indicator). In the example of this figure, the destination floor indicator 120 for the B car displays that the eighth floor and the ninth floor allocated to the B car have been reassigned to the A car.

  Here, in the present embodiment, the control unit 11 does not change the assignment of the destination floor call that occurred on a floor other than the specific floor. This is because the destination floor indicator 120 is not provided on floors other than the specific floor. Hereinafter, floors other than the specific floor are appropriately referred to as “allocation-impossible floors”.

2-3. Operation of Destination Floor Registration Apparatus Destination floor registration apparatus 30 accepts a user's destination floor registration operation at operation unit 35. The control unit 31 of the destination floor registration device 30 includes destination floor information indicating the destination floor registered by the user and departure floor information indicating the installation floor of the destination floor registration device 30 where the operation of registering the destination floor has been performed. An allocation request signal including the destination floor registration device 30 and device identification information for identifying the destination floor registration device 30 is generated. The control unit 31 of the destination floor registration device 30 outputs the generated assignment request signal to the group management control device 10.

  Further, when the control unit 31 of the destination floor registration device 30 receives the assigned car information indicating the assigned car from the group management control device 10 as a response to the above-mentioned assignment request signal, the destination floor registered by the user, The information indicating the assigned car indicated by the assigned car information is displayed on the display unit 34. Thereby, the destination floor registration device 30 notifies the user that the registered destination floor has been allocated to the displayed allocated number.

2-4. Specific Operation An elevator assignment process performed by the elevator group management control device 10 according to the first embodiment will be described. FIG. 7 is a flowchart illustrating an elevator assignment process performed by the elevator group management control device 10 according to the first embodiment. The processing according to this flowchart is performed when a new destination floor call occurs.

  The group management control device 10 determines whether or not a new destination floor call has occurred (S11). Specifically, the group management control device 10 determines whether a new destination floor call has occurred based on whether an assignment request signal has been received from the destination floor registration device 30.

  If a new destination floor call has not occurred (NO in S11), the group management control device 10 executes the determination in step S11 again.

  On the other hand, when a new destination floor call occurs (YES in S11), the group management control device 10 sets (stores) the departure floor of the new destination floor call as F and the destination floor as D (S12).

  The group management control device 10 sets 1 as the machine number c (S13). In the present embodiment, c is 1 to 3 because three elevators 60A to 60C (units) are provided. The elevator 60A is the first car, the elevator 60B is the second car, and the elevator 60C is the third car.

  The group management control device 10 sets the first floor as the departure floor f to be calculated (S14).

  The group management control device 10 tentatively assigns the destination floor calls of the departure floor F and the destination floor D to the car No. c, simulates the operation of the car No. c, and uses all users assigned to the car c (use of the temporary assignment). The estimated waiting time wt [p] and the estimated boarding time bt [p] are obtained (S15). The operation of the c-th car in the simulation is performed by, for example, a selective collective method. The selective collective system is a driving system in which passengers moving in the same direction as the driving direction are shared with priority given to maintaining the driving direction. Note that the present invention is also applicable to a case where the operation system is another system.

  The group management control device 10 initializes the predicted waiting time maximum value max_wt [c], the predicted waiting time total value sum_wt [c], and the predicted riding time total value sum_bt [c] to zero (0) (S16). .

  The group management control device 10 sets the first floor as the destination floor d to be calculated (S17).

  The group management control device 10 determines whether the departure floor f to be calculated is equal to the destination floor d to be calculated (S18).

  If the departure floor f to be calculated is equal to the destination floor d to be calculated (YES in S18), the group management control device 10 adds 1 to the destination floor d to be calculated (S19), and again determines in step S18. Execute

  If the departure floor f to be calculated is not equal to the destination floor d to be calculated (NO in S18), the group management control device 10 has already assigned the destination floor call of the departure floor f and the destination floor d to the No. c machine. It is determined whether or not there is (S20).

  If not assigned (NO in S20), the group management control device 10 determines whether or not the destination floor d is the highest floor (S21).

  When the destination floor d is not the top floor (NO in S21), the group management control device 10 adds 1 to the destination floor d in step S19, and executes the processing after step S18. That is, the group management control device 10 executes the processing after step S18 for the next destination floor.

  If the destination floor d is the top floor (YES in S21), the group management control device 10 determines whether the departure floor f is the top floor (S22).

  If the departure floor f is not the top floor (NO in S22), the group management control device 10 adds 1 to the departure floor f (S23), and sets 1 as the destination floor d in step S17. That is, the group management control device 10 executes the processing after step S17 for the next departure floor.

When the departure floor f is the top floor (YES in S22), the group management control device 10 obtains an evaluation value E [c] related to the allocation based on Equation 1 (S24).

(Equation 1)
E [c] = Asum_wt [c] + Bsum_bt [c] + Cmax_wt [c]

Here, as described above, sum_wt [c] is the total value of the estimated waiting times wt [p] of all the users (including the temporarily assigned users) assigned to the car No. c. sum_bt [c] is the sum of the estimated ride times bt [p] of all the users (including the temporarily assigned users) assigned to the car No. c. max_wt [c] is the maximum value of the predicted waiting time wt [p] of all the users (including the temporarily assigned users) assigned to the car No. c. In the process according to the flowchart, only max_wt [c] for a user related to a destination floor call generated on a floor other than the specific floor (allocation-impossible floor) is used. For a destination floor call that has occurred on a floor where the allocation can be changed, long wait can be avoided by changing the allocation, and therefore, it is not a target when calculating max_wt [c]. A, B, and C are coefficients having positive values, and are set by simulation or experiment according to the content and degree of the effect to be obtained.

  The group management control device 10 determines whether or not the car number c is equal to the number of elevators 60 (S25). That is, it is determined whether or not the determination in each of the above steps has been completed for all the units.

  If the car number c is not equal to the number of the elevators 60 (NO in S25), the group management control device 10 adds 1 to the departure floor f (S26), and sets 1 as the departure floor f in step S14. That is, the group management control device 10 executes the processing after step S14 for the next car.

  If the car number c is equal to the number of the elevators 60 (YES in S25), the group management control device 10 determines the car having the smallest evaluation value E [c] related to the allocation as the car to be allocated (S27). And the process after step S11 is executed again.

  Here, in the above step S20, when it is determined that the destination floor call of the departure floor f and the destination floor d is already assigned to the car No. c (YES in S20), the group management control device 10 determines The user number p is set (stored) for the user associated with the destination floor call (S28).

  The group management control device 10 determines whether or not the departure floor f to be calculated is an unchangeable floor (S29). Note that the group management control device 10 stores information indicating the floor on which the allocation cannot be changed in the storage unit 12 as data in advance.

  If the departure floor f to be calculated is an unchangeable floor (YES in S29), the group management control device 10 sets the predicted waiting time wt [p] of the user with the user number p to the predicted waiting time maximum value. It is determined whether it is larger than max_wt [c] (S30).

  If the predicted waiting time wt [p] is longer than the predicted waiting time maximum value max_wt [c] (YES in S30), the group management control device 10 sets the predicted waiting time wt [p] as the maximum value max_wt [c]. (Storing) (S31).

  When the predicted waiting time wt [p] is not longer than the predicted waiting time maximum value max_wt [c] (NO in S30), when step S31 is executed, or when the departure floor f to be calculated cannot be reassigned If the floor is not the floor (NO in S29), the group management control device 10 uses the sum sum_wt [c] of the current predicted waiting time wt [p] as the total sum_wt [c] of the predicted waiting time wt [p]. The predicted waiting time wt [p] of the user with the user number p is added (S32).

  The group management control device 10 adds the predicted ride time bt [p] of the user with the user number p to the current predicted ride time total value sum_bt [c] as the predicted ride time total value sum_bt [c]. Is set (S33).

  The group management control device 10 determines whether or not the processing of steps S28 to S33 has been completed for all the destination floor calls of the departure floor f and the destination floor d already allocated to the car No. c (S34).

  If the above-mentioned processing has not been completed for all the destination floor calls of the departure floor f and the destination floor d already allocated to the car No. c (NO in S34), the group management control device 10 performs the processing after step S28. Is executed again.

  When the above processing is completed for all the destination floor calls of the departure floor f and the destination floor d already assigned to the car No. c (YES in S34), the group management control device 10 performs the processing after step S21 described above. Execute.

3. Operation The operation according to the present embodiment will be described. When a new destination floor call occurs, the group management control device 10 obtains an evaluation value E [c] related to allocation for each elevator 60 (unit) based on the above-described plurality of parameters, and the evaluation value E [c] Is assigned to the new destination floor call. In that case, in the present embodiment, as one of the plurality of parameters, a user whose departure floor is a predetermined unchangeable floor among all users allocated to the temporarily allocated elevator The value includes a value proportional to the predicted maximum waiting time max_wt [c] until the elevator can be boarded. Therefore, at the time of provisional assignment, a car whose predicted waiting time maximum value max_wt [c] on the floor where the assignment cannot be changed is larger than other cars also has an evaluation value E [c] larger than other cars. This makes it difficult to assign a new destination floor call. In other words, when the temporary assignment is performed, the assignment of the new destination floor call is suppressed to a car whose predicted waiting time maximum value max_wt [c] at the floor where the assignment cannot be changed is larger than that of the other car. Therefore, it is possible to suppress a long wait of a user who is waiting for a ride on a floor where the assignment cannot be changed.

(Embodiment 2)
In the first embodiment, as one of a plurality of parameters for obtaining the evaluation value E [c], a value proportional to the predicted waiting time maximum value max_wt [c] is included. As one of the parameters, instead of the predicted waiting time maximum value max_wt [c], the predicted waiting time wt [p] of all the users (all destination floor calls) assigned to the car No. c is determined from the longer one. The value includes a value proportional to the average value avg_wt [c] of the predicted waiting times wt [p] for the number.

  Specific processing will be described with reference to FIG. FIG. 8 is a flowchart illustrating an elevator assignment process performed by the group management control device according to the second embodiment. The flowchart of FIG. 8 is the same except that steps S30, S31, and S24 in the flowchart of FIG. 7 are replaced with steps S30A and S24A. The step numbers are also the same for the same processing. Hereinafter, a description will be given focusing on differences from the processing according to the flowchart in FIG. 7 of the first embodiment.

  That is, in step S29, if the departure floor f to be calculated is an unchangeable floor (YES in S29), the group management control device 10 transmits all users (all destination floor calls) allocated to the car No. c. An average value avg_wt [c] of a predetermined number of predicted waiting times wt [p] from the longest of the predicted waiting times wt [p] with respect to is calculated (S30A). The predetermined number is, for example, two or three.

  When the average value avg_wt [c] is obtained, the group management control device 10 executes the above-described step S32.

The group management control device 10 obtains the evaluation value E [c] related to the allocation based on Equation 2 (S24A).

(Equation 2)
E [c] = Asum_wt [c] + Bsum_bt [c] + Cavg_wt [c]

The definition of each parameter is as described in the first embodiment and the like.

  According to the present embodiment, the assigned car is appropriately controlled while suppressing a sudden change in the evaluation value E [c] due to a temporary sudden change in the predicted waiting time wt [p] of a certain user (a destination floor call). Decisions can be made.

(Embodiment 3)
In the first embodiment, a value proportional to the predicted waiting time maximum value max_wt [c] is included as one of a plurality of parameters for obtaining the evaluation value E [c]. As one of the parameters, instead of the predicted waiting time maximum value max_wt [c], the predicted waiting time wt [p] of all the users (all destination floor calls) assigned to the car No. c is determined from the longer one. The value includes a value proportional to the total value sum2_wt [c] of the predicted waiting times wt [p] for the number.

  Specific processing will be described with reference to FIG. FIG. 9 is a flowchart illustrating an elevator assignment process performed by the group management control device according to the third embodiment. Note that the flowchart of FIG. 9 is the same except that steps S30, S31, and S24 of the flowchart of FIG. 7 are replaced with steps S30B and S24B. The step numbers are also the same for the same processing. Hereinafter, a description will be given focusing on differences from the processing according to the flowchart in FIG. 7 of the first embodiment.

  That is, in step S29, if the departure floor f to be calculated is an unchangeable floor (YES in S29), the group management control device 10 transmits all users (all destination floor calls) allocated to the car No. c. A total sum2_wt [c] of a predetermined number of predicted waiting times wt [p] from the longest of the predicted waiting times wt [p] with respect to is calculated (S30B). The predetermined number is, for example, two or three.

  When the total value sum2_wt [c] is obtained, the group management control device 10 executes the above-described step S32.

The group management control device 10 obtains the evaluation value E [c] related to the allocation based on Expression 3 (S24B).

(Equation 3)
E [c] = Asum_wt [c] + Bsum_bt [c] + Csum2_wt [c]

The definition of each parameter is as described in the first embodiment and the like.

  According to the present embodiment, as in the second embodiment, a sudden change in the evaluation value E [c] due to a temporary sudden change in the predicted waiting time wt [p] of a certain user (destination floor call) is suppressed. Thus, it is possible to appropriately determine the assigned car.

(Embodiment 4)
In the above embodiments, the destination floor is registered (designated) using the destination floor registration device 30. However, in recent years, there is a destination floor registration system that can register (designate) a destination floor using not only the destination floor registration device 30 but also an information communication terminal such as a smartphone capable of wireless communication owned by the user. The present embodiment provides a technique suitable for such a system. The details will be described below.

  In such a system, when registration (designation) of a destination floor is performed using an information communication terminal possessed by a user, transmission of information on the change of allocation to the information communication terminal of the user by wireless communication is performed. Thus, the user can be notified of the change in the assignment. Therefore, in the present embodiment, when destination floor registration (destination floor designation) is performed using the information communication terminal, the group management control device 10 determines that the departure floor of the destination floor call related to the destination floor has no assignment change. Even when the floor is a possible floor, the allocation processing is performed assuming that the departure floor is a floor whose allocation can be changed. Further, the group management control device 10 thereafter changes the allocation as needed, and transmits the allocation change information to the information communication terminal.

  Specifically, when the destination floor is registered using the information communication terminal instead of the destination floor registration device 30, the group management control device 10 waits for the prediction of the user related to the destination floor registration. The time wt [p] is not set as the maximum value of the predicted waiting time max_wt [c]. More specifically, the group management control device 10 determines not the destination floor registration device 30 but the destination floor call related to the assignment request information received from the information communication terminal in the determination of step S29 in the flowchart of FIG. Regardless of whether or not the destination floor indicator 120 (destination floor indicator) is provided at the departure floor f of the destination floor call, it is determined that the departure floor f is not a floor whose assignment cannot be changed (NO). As a result, even when the departure floor f of the destination floor call is a non-allocation-changeable floor, the allocation processing is performed assuming that the departure floor f is the re-allocation-possible floor.

  In this example, as shown in FIG. 10, as the hardware, a communication device 130 capable of transmitting assignment request information, assignment number information, assignment change information, and the like by wireless communication with the information communication terminal CT is added, It is connected to the input / output interface 13. A dedicated application (program) is installed in the information communication terminal CT. A dedicated application for causing the information communication terminal CT (computer) to generate allocation request information according to the departure floor and the destination floor; a means for receiving allocation machine information and informing a display unit or the like; It functions as means for receiving the allocation change information and informing the display unit or the like of the information. Various known technologies and standards are available for wireless communication. According to this example, it is possible to appropriately suppress the long waiting of the user according to the means used for the destination floor registration (destination floor designation).

(Embodiment 5)
In the first embodiment, the predicted waiting time maximum value max_wt [c] is the predicted waiting time wt [of the user whose departure floor is a predetermined non-reassignable floor among all the users assigned to the provisionally assigned elevator. p] is the maximum predicted waiting time. However, the predicted waiting time maximum value max_wt [c] is the largest predicted waiting time among the predicted waiting times wt [p] of all the users (users on all floors) assigned to the temporarily assigned elevator. There may be.

  FIG. 11 is a flowchart illustrating an elevator assignment process performed by the group management control device according to the fifth embodiment. The flowchart of FIG. 11 is the same except that step S29 in the flowchart of FIG. 7 is deleted.

  In the present embodiment, since the determination as to whether or not the f-th floor is an unchangeable floor in step S29 of the first embodiment is omitted, in steps S30 to S33, the elevator is allocated to the temporarily allocated elevator. The maximum predicted waiting time among the predicted waiting times wt [p] of all users (users on all floors) is set as the predicted waiting time maximum value max_wt [c].

  Then, in step S24, the estimated waiting time maximum value max_wt [c] is substituted into the above-mentioned (Equation 1), whereby the evaluation value E [c] related to the allocation is obtained.

  In the present embodiment, as one of the plurality of parameters, the predicted waiting time maximum value max_wt which is the maximum value among the predicted waiting times wt [p] of all the users assigned to the temporarily assigned elevator. A value proportional to [c] is included. Therefore, when provisionally assigned, a car whose predicted waiting time maximum value max_wt [c] is larger than other cars also tends to have an evaluation value E [c] larger than other cars. Destination floor calls are less likely to be assigned. That is, at the time of provisional assignment, assignment of a new destination floor call is suppressed to a car whose predicted waiting time maximum value max_wt [c] is larger than other cars. For this reason, it is possible to prevent a waiting time of a user who is waiting for the car on each floor from becoming long. That is, it is possible to suppress a long wait of a user waiting for a ride on each floor. Here, as described above, when the predicted waiting time is equal to or longer than the predetermined time, the allocation can be changed on the floor where the allocation can be changed, so that long waiting is unlikely to occur from the beginning. Therefore, the floor where the waiting time of the user is likely to be long becomes a floor in which the assignment cannot be changed substantially. Therefore, what is set as the predicted waiting time maximum value max_wt [c] is substantially the predicted waiting time of a user who is waiting for a ride on a floor where the assignment cannot be changed. For this reason, when a temporary allocation includes a floor that cannot be reassigned as an allocated floor, the waiting time of a user who is waiting to board the car at the floor where the allocation cannot be changed is expected to wait. It is easy to set as the time maximum value max_wt [c], and as a result, long waiting of a user waiting for a ride on a floor where the assignment cannot be changed is suppressed.

(Embodiment 6)
In the second embodiment, the average value avg_wt [c] is equal to the estimated waiting time wt [p] of the user whose departure floor is a predetermined unchangeable floor among all the users allocated to the temporarily allocated elevator. It is an average value of a predetermined number of predicted waiting times wt [p] from the longest one. However, the average value avg_wt [c] is equal to the predicted waiting time of a predetermined number from the longest of the predicted waiting times wt [p] of all the users (users on all floors) assigned to the temporarily assigned elevator. The average value of wt [p] may be used.

  FIG. 12 is a flowchart illustrating an elevator assignment process performed by the group management control device according to the sixth embodiment. The flowchart in FIG. 12 is the same except that step S29 in the flowchart in FIG. 8 is deleted.

  In the present embodiment, since the determination as to whether or not the floor f is an unchangeable floor in step S29 of the second embodiment is omitted, in steps S30A to S33, the elevator is allocated to the temporarily allocated elevator. The average value of a predetermined number of predicted waiting times wt [p] from the longest of the predicted waiting times wt [p] of all users (users on all floors) is set as an average value avg_wt [c]. It will be.

  Then, in step S24A, by substituting the average value avg_wt [c] into the above (Equation 2), the evaluation value E [c] related to the allocation is obtained.

  According to the present embodiment, as one of the plurality of parameters, a predetermined number of predicted waiting times wt [p] of the predicted waiting times wt [p] of all users (users of all floors) from the longer one. In the case where a value proportional to the average value avg_wt [c] of [p] is used, the evaluation value E [c] due to a temporary sudden change in the predicted waiting time wt [p] of a certain user (destination floor call) is used. It is possible to appropriately determine the assigned car while suppressing a sudden change.

(Embodiment 7)
In the third embodiment, the total value sum2_wt [c] is the estimated waiting time wt [p] of the user whose departure floor is a predetermined non-reassignable floor among all the users allocated to the provisionally allocated elevator. It is a total value of a predetermined number of predicted waiting times wt [p] from the longest one. However, the total value sum2_wt [c] is a predetermined number of predicted waiting times from the longer of the predicted waiting times wt [p] of all users (users on all floors) assigned to the provisionally assigned elevator. It may be the total value of wt [p].

  FIG. 13 is a flowchart illustrating an elevator assignment process performed by the group management control device according to the seventh embodiment. The flowchart of FIG. 13 is the same as the flowchart of FIG. 9 except that step S29 is deleted.

  In the present embodiment, since the determination of whether or not the f floor is an unchangeable floor in step S29 of the third embodiment is omitted, in steps S30B to S33, the elevator is allocated to the temporarily allocated elevator. The total value of a predetermined number of predicted waiting times wt [p] from the longest of the predicted waiting times wt [p] of all users (users on all floors) is set as a total value sum2_wt [c]. It will be.

  Then, in step S24B, by substituting the total value sum2_wt [c] into the above (Equation 3), the evaluation value E [c] related to the allocation is obtained.

  According to the present embodiment, as one of the plurality of parameters, a predetermined number of predicted waiting times wt [p] of the predicted waiting times wt [p] of all users (users of all floors) from the longer one. In the case of using a value proportional to the total value sum2_wt [c] of [p], the evaluation value E [c] of the evaluation waiting time wt [p] of a certain user (destination floor call) due to a temporary sudden change in the waiting time wt [p] It is possible to appropriately determine the assigned car while suppressing a sudden change.
