Description

Technical Field

[0001] The present invention relates to the field of industrial design, and in particular to a method and system for division of labor in structural design of a manufacturing equipment production line. Background Art

[0002] It has become a consensus that reasonable division of labor can improve production efficiency, and this is also true in the field of intelligent manufacturing equipment design. Based on the design knowledge points of the manufacturing equipment design project, the entire design project is divided into design sub-projects with relatively simple knowledge, so that the knowledge complexity involved in a single design sub-project is reduced, thereby improving the design efficiency, such as "A method, system and storage medium for generating an industrial design process" (patent number: CN116204939A). This method divides labor from the perspective of knowledge complexity, which reduces the complexity of a single design sub-project to a certain extent and improves design efficiency. However, when faced with the structural design project of the entire production line of manufacturing equipment, this method cannot be well applied. And only dividing labor from the perspective of knowledge complexity without considering the workload may lead to uncontrollable overall project progress. Summary of the invention

[0003] In view of the above problems existing in the prior art, the present invention provides a method and system for designing a production line structure of manufacturing equipment.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] The present invention provides a method for designing a production line structure of manufacturing equipment, the method comprising:

[0006] S1. Construct a tree structure of manufacturing equipment structure design content consisting of module types, modules, design points, and knowledge points;

[0007] S2. According to the design content tree structure, split the manufacturing equipment production line structure design content into the tree structure;

[0008] S3. Set the working time threshold of the project division task package, calculate the sum of the working hours of all modules of the same module type, and compare and judge:

[0009] If the sum of the working hours of all modules in the same module type is less than or equal to the threshold, all modules in the module type are divided into the same project division task package;

[0010] If the sum of the working hours of all modules of the same module type is greater than the threshold, the similarity between each module of the module type and the whole composed of the remaining modules is calculated, and the module with the smallest similarity value is eliminated. The sum of the working hours of all the remaining modules is calculated and compared with the threshold until the sum of the working hours of all the remaining modules is less than or equal to the threshold. In this case, all the remaining modules are currently a project division task package;

[0011] For all modules eliminated in the above steps, the sum of working hours is calculated again, the threshold is determined, the module with the smallest similarity is eliminated, and the project division task package is formed, until all modules in the current module type are assigned to the project division task package;

[0012] S4. Perform step 3 for other module types of manufacturing equipment in sequence until all modules in all module types are allocated to the project division task package;

[0013] S5. Output the overall division of labor plan for the new manufacturing equipment production line design in the form of a division of labor plan tree structure.

[0020] Furthermore, in step S3, the sum of the working hours of all modules of the same type is calculated, specifically:

[0021] First, calculate the single module working hours, which is calculated by multiplying the working hours of the module type to which the module belongs by the module difficulty coefficient, where the difficulty coefficient is a function related to the number of design points, the total number of knowledge points, and the number of knowledge point types contained in the module;

[0022] Then calculate the sum of all module working hours in the same type of modules, where the sum of module working hours is the accumulation of all single module working hours minus repeated working hours;

[0023] The repetitive working hours are the ratio of the number of identical knowledge points involved in all modules under the current module type to the total number of knowledge points multiplied by the sum of the working hours of all modules.

[0024] Furthermore, in step S3, a working time threshold of the project division task package is set, and the working time threshold of the project division task package is 1 to 50 hours, preferably 2 to 12 hours.

[0025] Furthermore, in step S3, the similarity between each module in the module type and the whole composed of the remaining modules is calculated, and the similarity is the ratio of the number of the same knowledge point types between the current module and the whole composed of the remaining modules multiplied by the number of the same knowledge points possessed by the whole composed of the remaining modules multiplied by the number of the knowledge point types contained in the whole composed of the remaining modules multiplied by the total number of knowledge points, that is:

[0026]

[0027] The number of the same knowledge points between the current module and the rest of the modules.

[0028] The number of knowledge point types included in the whole composed of other modules;

[0029] The number of common knowledge points between the current module and the rest of the modules;

[0030] The total number of knowledge points in the whole composed of other modules.

[0031] Furthermore, in the step S5, the overall division of labor plan for the new manufacturing equipment production line design is output in the form of a division of labor plan tree structure, and the division of labor plan tree structure includes module type, project division of labor task package, module, and design points, wherein the project division of labor task package includes the working hours of the division of labor task package and the module numbers contained therein.

[0032] The present invention also provides a manufacturing equipment production line structure design division system, including the above method, the system includes an input module, a storage module, a calculation module, a combination module and an output module;

[0033] The input module is used to input the structural design content of the manufacturing equipment production line, the man-hour threshold of the project division task package, and the man-hour corresponding to the module type;

[0034] The storage module is used to store the constructed manufacturing equipment production line structure design content tree structure, the input new manufacturing equipment production line structure design content, and the input project division task package working time threshold;

[0035] The calculation module is used to calculate the module working hours, execute the natural language processing algorithm model, the similarity value of the module of the same module type and the whole composed of the remaining modules, and the working hours of the whole composed of the remaining modules;

[0036] The combination module is used to combine modules of the same module type;
