Description

Multidimensional Hierarchical Production Capacity Accounting Method

technical field

The present invention relates to a multi-dimensional hierarchical production capacity accounting method, especially one based on the ISA-95 standard (international standard for enterprise system and control system integration), which establishes a production model from the three dimensions of resources, organization and time, and calculates production capacity Methods.

Background technique

Semiconductor packaging and testing companies are typical foundry production models. Semiconductor products, as components of electronic products, have strong timeliness, and fast and accurate delivery time is what downstream manufacturers desire. The diversity of customer demand for products has changed the production mode of the enterprise from standardization to customization, from inventory to order. Under the order-based production model, what the company sells is no longer the finished product in the strict sense, but the production capacity of the company. Due to the unpreservability of production capacity, the modeling and optimization control of production capacity is particularly important.

In the flexible manufacturing system, G. Liberopoulos, based on the analysis of the substitutability, non-constant velocity, flexibility and other characteristics of the production equipment, established a production capacity model according to the different productivity of different parts produced by the equipment. Ronald Buitenhek et al. established a production capacity model for the production of multiple products, machines in parallel, and a fixed production rate, and used it to simulate and analyze the performance in the iterative production process. J.Q.HU et al. analyzed the production capacity management problems caused by external demand changes in a single product manufacturing system. WilhelmDangelmaier et al. used object-oriented methods to establish a continuous manufacturing model, and established a production capacity model based on elements such as material flow, production stages, production lines, and shift time.

As an important resource of the enterprise, the production capacity is mainly managed through the work center in the traditional ERP system. Although the setting of the work center facilitates the collection of production costs, the production capacity lacks the support of basic data. Zhang Lemin and others statistically analyze the data collected by the manufacturing execution system to improve the production capacity data of the work center, thereby improving the accuracy of the capacity planning of the ERP system. Yi Xingbin constructed the production capacity accounting method of the unit based on the capacity accounting of various equipment such as piercing machines, pipe rolling machines, and pipe jacking machines that make up the seamless steel pipe production line. Li Yu et al. summarized the modeling methods of the enterprise capability model, and established a prototype system of the enterprise capability model.

The above literatures have made active attempts to construct production capacity models, some of which have been used in production practice. From the perspective of production planning and control, the support of these capability models for production planning and control is not perfect, and lacks unity or operability. On the one hand, these models only describe how much can be produced from a quantitative dimension, and do not consider the qualification capacity of resources from a qualitative perspective. On the other hand, it rarely describes how the production capacity is calculated from the bottom production resources to the production organizations at all levels.

The production capacity model defined by the ISA-95 standard is a collection of production resources, including personnel capabilities, equipment capabilities, material capabilities, and process section capabilities, where process section capabilities are iterations of personnel capabilities, equipment capabilities, and material capabilities. Therefore, the production capacity model defined in the ISA-95 standard only considers the production resources of the enterprise's personnel capacity, equipment capacity and material capacity. However, although production capacity is built on resources such as people, machines, and materials, these resources belong to a certain organization, and the organization belongs to different levels. At the same time, for the same resource in different time periods, the production capacity changes in the time dimension due to different capacity plans and maintenance plans. Therefore, to accurately describe production capacity, it is necessary to define it in three dimensions: production organization, time, and resources.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a multi-dimensional hierarchical production capacity accounting method, which establishes the production capacity in the two angles of product quality and quantity, and in the three dimensions of resources, production organization and time.

According to the technical solution provided by the present invention, the multi-dimensional hierarchical production capacity accounting method is characterized in that the method includes the following steps:

Step 5: Use the enterprise model to characterize the enterprise production capacity that changes with the effective working time of the enterprise and the rated working hours of the product; or, characterize the production capacity of the enterprise composed of the production plants based on the production capacity of the production plants.

Fig. 2 is a hierarchical relationship diagram of the production capacity accounting method of the present invention.

Detailed ways

The present invention will be further described below in conjunction with specific drawings.

The production capacity accounting method of the present invention is based on an extended three-dimensional production capacity model, as shown in FIG. 1 , the three-dimensional production capacity model includes an organization dimension, a time dimension and a resource dimension.

The organizational dimension refers to the production organization structure of an enterprise, including groups, companies, factories, workshops, and production lines/units. The production line/unit is composed of specific enterprise resources such as people, machines, and materials. There are parallel and serial processes among production organizations. line, synchronization, etc.

The time dimension refers to the division of time into annual, quarterly, monthly, weekly, daily, shift and other production periods, and the production capacity accounting is carried out in different production periods. In an enterprise, in order to achieve the capacity balance between different production organizations, different Organizations implement different production calendars.

The resource dimension is the carrier of production capacity. Personnel, materials, and equipment not only have a certain ability level, but also a certain processing speed; the former, such as whether the personnel are skilled workers, semi-skilled workers or novice, the processing accuracy of the equipment, equipment level , machine modification time, fault handling capability, material strength, etc.; the latter, the quantity processed per unit time is different when different personnel, equipment, and materials process the same product.

The hierarchical relationship of the organizational dimensions of the extended 3D production capacity model is specifically shown in Figure 2. Production lines/units are composed of production resources such as personnel, materials, and equipment; The form constitutes the workshop. The workshop can be composed of a flexible production line/unit (that is, there is no physical device to connect the production resources, and it is only constrained by the process sequence), or it can be composed of an arrangement of flow production lines/units (that is, the production resources rely on conveyor belts, Hinge connection, distributed on both sides in turn, the workpiece or product walks on the assembly line according to a certain rhythm); the workshop constitutes the factory, and the factory constitutes the enterprise.

The symbols involved in the embodiments of the present invention are shown in Table 1.

The accounting of production capacity described in the present invention is based on production capacity model, adopts the method from bottom to top, and its concrete steps are:

Step 1: Calculate the production capacity of personnel and equipment according to the capabilities of personnel, equipment, materials and other resources and the shift system;

或者，人员生产能力为有效工作时间乘以人员工作效率乘以单位时间加工速度，即 ${\mathrm{PC}}_{\mathrm{pr}}=F_e\left(C_{\mathrm{ps}}^t\right)\×\mathrm{\ξ}\×V_s;$ a. When calculating personnel production capacity, if the personnel is in the form of a single person, then within the planning period, the personnel production capacity is the effective working time multiplied by the personnel work efficiency and then divided by the rated working hours, that is

Alternatively, the personnel productivity is the effective working time multiplied by the personnel work efficiency multiplied by the processing speed per unit time, that is ${\mathrm{PC}}_{\mathrm{pr}}=f_e\left(C_{\mathrm{ps}}^t\right)\×\mathrm{\ξ}\×V_{\mathrm{the\; s}};$

If the personnel are in the form of a team, then the production capacity of the team is the sum of the production capacity of each person in the team, that is ${\mathrm{PC}}_{\mathrm{pr}}=\underset{i=1}{\overset{I}{\mathrm{\Σ}}}\frac{f_e\left(C_{\mathrm{ps}}^t\right)\×\mathrm{\ξ}}{T_{\mathrm{the\; si}}}$ or ${\mathrm{PC}}_{\mathrm{pr}}=\underset{i=1}{\overset{I}{\mathrm{\Σ}}}{f}_e\left(C_{\mathrm{ps}}^t\right)\×\mathrm{\ξ}\×V_{\mathrm{the\; s}}^i;$

或者，设备生产能力为有效工作时间乘以设备工作效率乘以设备加工速度，即

b. When calculating the production capacity of equipment, if the equipment is in the form of a single unit, then the production capacity of the equipment is the effective working time in the planning period multiplied by the working efficiency of the equipment and then divided by the rated working hours of the equipment to produce a single product, that is

Alternatively, the equipment production capacity is the effective working time multiplied by the equipment working efficiency multiplied by the equipment processing speed, namely

In actual production, equipment is often grouped and managed according to product objects or process objects. At this time, the production capacity calculation method of the non-uniform speed equipment group is the sum of the production capacities of all equipment in the equipment group, that is ${\mathrm{PC}}_{\mathrm{eq}}=\underset{j=1}{\overset{J}{\mathrm{\Σ}}}\frac{f_e\left(C_{\mathrm{eq}}^t\right)\×\mathrm{\ϵ}}{T_{\mathrm{sj}}}$ or ${\mathrm{PC}}_{\mathrm{eq}}=\underset{j=1}{\overset{J}{\mathrm{\Σ}}}{f}_e\left(C_{\mathrm{eq}}^t\right)\×\mathrm{\ϵ}\×V_{\mathrm{the\; s}}^j;$

Step 2: Calculate the production capacity of the production line according to the configuration of the production line equipment;

If the production line is an assembly line (that is, the production resources are connected by conveyor belts and hinges, and are distributed on both sides in turn, and the workpiece or product passes through the assembly line according to a certain beat), then the production capacity of the production line is the ratio of the effective working time of the production line to the beat of the production line ,Right now

If the production line is a flexible assembly line (the production resources are not connected by physical devices, only restricted by the process sequence), its production capacity is equal to the production capacity of the bottleneck process equipment group, that is ${\mathrm{PC}}_{\mathrm{eq}}=\underset{j=1}{\overset{J}{\mathrm{\Σ}}}\frac{f_e\left(C_{\mathrm{eq}}^t\right)\×\mathrm{\ϵ}}{T_{\mathrm{sj}}}$ or ${\mathrm{PC}}_{\mathrm{eq}}=\underset{j=1}{\overset{J}{\mathrm{\Σ}}}{f}_e\left(C_{\mathrm{eq}}^t\right)\×\mathrm{\ϵ}\×V_{\mathrm{the\; s}}^j;$

Step 3: Calculate the production capacity of the workshop according to the number of production lines in the production workshop;

If the production capacity of the production line in the workshop is unknown, then the production capacity of the workshop is the ratio of the effective working time of the workshop to the rated working hours of representative products, that is

If the production capacity of the production line is known, the production capacity of the workshop is the sum of the production capacity of the production line in the workshop, that is ${\mathrm{PC}}_{\mathrm{sf}}=\mathrm{Min}(\underset{l=1}{\overset{L}{\mathrm{\Σ}}}{\mathrm{PC}}_{p1}^{l1},\underset{l=1}{\overset{L}{\mathrm{\Σ}}}{\mathrm{PC}}_{\mathrm{pl}}^{l2},...\underset{l=1}{\overset{L}{\mathrm{\Σ}}}{\mathrm{PC}}_{\mathrm{pl}}^{\mathrm{lO}});$

Step 4: Calculate the production capacity of the production plant based on the number of internal production workshops of the production plant;

If the production capacity of the workshop in the production plant is unknown, then the production capacity of the production plant is the ratio of the effective working time of the factory to the rated working time of the representative product, that is,

If the production capacity of the workshop is known, the production capacity of the production plant is the sum of the production capacity of the workshops that make up the production plant, that is ${\mathrm{PC}}_{\mathrm{fa}}=\mathrm{Min}(\underset{\mathrm{the\; s}=1}{\overset{S}{\mathrm{\Σ}}}{\mathrm{PC}}_{\mathrm{sf}}^{\mathrm{the\; s}1},\underset{\mathrm{the\; s}=1}{\overset{S}{\mathrm{\Σ}}}{\mathrm{PC}}_{\mathrm{sf}}^{\mathrm{the\; s}2},...\underset{\mathrm{the\; s}=1}{\overset{S}{\mathrm{\Σ}}}{\mathrm{PC}}_{\mathrm{sf}}^{\mathrm{sO}});$

Step 5: Calculate the production capacity of the enterprise according to the supply and demand relationship between the internal production plants and the number of production plants;

If the production capacity of each production plant in the enterprise is unknown, then the production capacity of the enterprise is

If the production capacity of the production plant is known, the production capacity of the enterprise is ${\mathrm{PC}}_{\mathrm{en}}=\mathrm{Min}(\underset{f=1}{\overset{f}{\mathrm{\Σ}}}{\mathrm{PC}}_{\mathrm{fa}}^{f1},\underset{f=1}{\overset{f}{\mathrm{\Σ}}}{\mathrm{PC}}_{\mathrm{fa}}^{f2},...\underset{f=1}{\overset{f}{\mathrm{\Σ}}}{\mathrm{PC}}_{\mathrm{fa}}^{\mathrm{fO}}).$

The following is a detailed description based on the production capacity calculation example of a semiconductor packaging and testing company. The company has three factories, which are the first packaging factory, the second packaging factory and the testing factory (there are three production methods for products, only assembly, only testing, and assembly testing. For the last production method, the first packaging factory and the second packaging factory produce Products can enter the testing factory for testing and processing). The first packaging factory is divided into seven process sections according to the production process, namely scribing, chip loading, bonding, plastic packaging, electroplating, printing and rib cutting. The second packaging factory divides the equipment into four virtual production lines according to the process route of the product variety, and adopts the flexible assembly line production method.

The requirements for the qualification and ability attributes of resources are different in different production stages. For example, the grinding stage in scribing is an important link. The operator must be a senior operator certified by the state to undertake it, and the abrasive tool operation only needs ordinary operators. Can. In the same bonding stage, the bonding machine only needs ordinary operators, while the vehicle body must be a senior operator.

The exact production capacity of each production organization is closely related to the organizational calendar. The enterprise adopts the natural year as the business year, and the calendar mode mainly includes administrative shifts and three shifts. The administrative class implements the national statutory holiday system. Taking 2012 as an example, excluding weekends and holidays, the company has approved 251 effective working days for the year, and 8 hours of effective working time per day; three shifts, three shifts in the morning, middle and evening , The effective working time of each shift is 8 hours.

As shown in Table 2, the third line is the UPH (Unit Per Hour) of the machines in each process of the semiconductor packaging and testing production line, and the last two lines are the various types of machines included in the workshops of the first semiconductor assembly plant and the second assembly plant quantity.

The detailed accounting steps are as follows:

Step 1. Personnel and equipment capacity accounting: this step is omitted;

Step 2. Workshop production capacity calculation:

可知，封装一厂的各个车间（由多种设备组并列组成）的生产能力为：(1) Since the production capacity of each machine in each workshop of the packaging factory is known, and the workshop does not contain multiple processes, the production capacity of each workshop is the sum of the production capacities of all machines in the workshop, and the working efficiency of the equipment is 1, all use the administrative class; according to

It can be seen that the production capacity of each workshop (composed of multiple equipment groups in parallel) in the first packaging factory is:

The production capacity of the dicing workshop of the first packaging factory is $\mathrm{PC}_{\mathrm{sf}-h}^1=\mathrm{PC}_{\mathrm{eq}-h}^1=\mathrm{PC}_{\mathrm{eq}-h}^{m11}{}_1+\mathrm{PC}_{\mathrm{eq}-h}^{m12}{}_1=342400\mathrm{unit};$

(b) Chip loading workshop of the first packaging factory:

The production capacity of the machine M21 in the first packaging factory is $\mathrm{PC}_{\mathrm{eq}-z}^{m\mathrm{twenty\; one}}{}_1=8\×1\×4400\×3=105600\mathrm{unit},$

The production capacity of the machine M22 in the first packaging factory is $\mathrm{PC}_{\mathrm{eq}-z}^{m\mathrm{twenty\; two}}{}_1=8\×1\×5200\×0=0,$

The production capacity of the machine M23 in the first packaging factory is $\mathrm{PC}_{\mathrm{eq}-z}^{m\mathrm{twenty\; three}}{}_1=8\×1\×4700\×6=225600\mathrm{unit},$

Step 3. Factory production capacity calculation:

可知，封装一厂的生产能力为：Because the production capacity of each workshop of the first assembly plant and the second assembly plant has been calculated, and the processes of each workshop in the factory are related to the previous and subsequent processes, and each workshop has no parallel workshops, so its production capacity is the production capacity of each workshop The least capable one; according to

It can be seen that the production capacity of the first packaging factory is:

$\mathrm{<span\; class="notranslate">\; PC</span>}_{\mathrm{<span\; class="notranslate">\; fa</span>}}^{\mathrm{<span\; class="notranslate">\; 1</span>}}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; Min</span>}<span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; PC</span>}_{\mathrm{<span\; class="notranslate">\; sf</span>}<span\; class="notranslate">\; -</span>\mathrm{<span\; class="notranslate">\; q</span>}}^{\mathrm{<span\; class="notranslate">\; 1</span>}}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; PC</span>}_{\mathrm{<span\; class="notranslate">\; sf</span>}<span\; class="notranslate">\; -</span>\mathrm{<span\; class="notranslate">\; z</span>}}^{\mathrm{<span\; class="notranslate">\; 1</span>}}<span\; class="notranslate">\; ,</span><span\; class="notranslate">\; .</span><span\; class="notranslate">\; .</span><span\; class="notranslate">\; .</span><span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; PC</span>}_{\mathrm{<span\; class="notranslate">\; sf</span>}<span\; class="notranslate">\; -</span>\mathrm{<span\; class="notranslate">\; q</span>}}^{\mathrm{<span\; class="notranslate">\; 1</span>}}<span\; class="notranslate">\; )</span><span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; PC</span>}_{\mathrm{<span\; class="notranslate">\; sf</span>}<span\; class="notranslate">\; -</span>\mathrm{<span\; class="notranslate">\; j</span>}}^{\mathrm{<span\; class="notranslate">\; 1</span>}}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; 326400</span>}\mathrm{<span\; class="notranslate">\; unit</span>}<span\; class="notranslate">\; ,</span>$

The production capacity of the Second Packaging Factory is:

$\mathrm{<span\; class="notranslate">\; PC</span>}_{\mathrm{<span\; class="notranslate">\; fa</span>}}^{\mathrm{<span\; class="notranslate">\; 2</span>}}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; Min</span>}<span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; PC</span>}_{\mathrm{<span\; class="notranslate">\; sf</span>}<span\; class="notranslate">\; -</span>\mathrm{<span\; class="notranslate">\; q</span>}}^{\mathrm{<span\; class="notranslate">\; 2</span>}}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; PC</span>}_{\mathrm{<span\; class="notranslate">\; sf</span>}<span\; class="notranslate">\; -</span>\mathrm{<span\; class="notranslate">\; z</span>}}^{\mathrm{<span\; class="notranslate">\; 2</span>}}<span\; class="notranslate">\; ,</span><span\; class="notranslate">\; .</span><span\; class="notranslate">\; .</span><span\; class="notranslate">\; .</span><span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; PC</span>}_{\mathrm{<span\; class="notranslate">\; sf</span>}<span\; class="notranslate">\; -</span>\mathrm{<span\; class="notranslate">\; q</span>}}^{\mathrm{<span\; class="notranslate">\; 2</span>}}<span\; class="notranslate">\; )</span><span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; PC</span>}_{\mathrm{<span\; class="notranslate">\; sf</span>}<span\; class="notranslate">\; -</span>\mathrm{<span\; class="notranslate">\; the\; s</span>}}^{\mathrm{<span\; class="notranslate">\; 2</span>}}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; 400000</span>}\mathrm{<span\; class="notranslate">\; unit</span>}<span\; class="notranslate">\; ;</span>$

Step 4. Enterprise production capacity calculation:

Since the theoretical bottleneck of semiconductor packaging and testing enterprises lies in the production capacity of packaging machines, the testing factory is manual production. Compared with the assembly factory, its production capacity can be flexibly adjusted by temporarily working overtime or recruiting new employees, so there is no need to consider the production capacity of the testing factory. , the production capacity of the enterprise is the sum of the production capacity of the first packaging factory and the second packaging factory; ${\mathrm{PC}}_{\mathrm{en}}=\mathrm{Min}(\underset{f=1}{\overset{f}{\mathrm{\&Sigma;}}}{\mathrm{PC}}_{\mathrm{fa}}^{f1},\underset{f=1}{\overset{f}{\mathrm{\&Sigma;}}}{\mathrm{PC}}_{\mathrm{fa}}^{f2},...\underset{f=1}{\overset{f}{\mathrm{\&Sigma;}}}{\mathrm{PC}}_{\mathrm{fa}}^{\mathrm{fO}})$ It can be seen that:

The production capacity of the enterprise is ${\mathrm{PC}}_{\mathrm{en}}=\mathrm{Min}\left(\underset{i=1}{\overset{2}{\mathrm{\&Sigma;}}}\mathrm{PC}_{\mathrm{fa}}^i\right)=\underset{i=1}{\overset{2}{\mathrm{\&Sigma;}}}\mathrm{PC}_{\mathrm{fa}}^i=726400\mathrm{unit}.$
