A machining workshop layout design method and system based on a design structure matrix

Abstract

The invention discloses a machining workshop layout design method and system based on a design structure matrix. Firstly, the logistics relation between a welding production line and a material bufferarea is analyzed; then, according to the occupied area and the preliminary layout of the two types of regions; a layout pattern is provided. The method comprises the steps of calculating main equipment and labor quotas of an automobile welding workshop, discussing the composition of an auxiliary production area and the non-logistics relationship between the auxiliary production area and a weldingproduction line and a material buffer area, obtaining the comprehensive relationship of all the areas through weighted calculation in combination with the obtained logistics relationship, determiningan optimal scheme by adopting a comprehensive evaluation method, and giving a final layout diagram. According to the method, a design structure matrix and automobile workshop layout design are combined; meanwhile, all areas of the workshop and the logistics and non-logistics relation between the areas are considered, a design structure matrix is used for simply and vividly displaying components of the workshop, a designer can better understand the system structure, and clustering, sorting and other analysis methods are used for reasonably designing the layout of the workshop.

Description

technical field [0001] The invention relates to the technical field of automobile workshop layout, in particular to an automobile workshop layout design method and system based on a design structure matrix. Background technique [0002] The process flow of the automobile workshop is to combine the processing of various parts manufactured by other workshops into a whole. The processing quality of the car workshop determines the quality of the vehicle, which directly affects the acceptance of consumers and the final sales of the car. At present, the domestic workshop layout design research focuses on the improvement and optimization of various algorithms, such as genetic algorithm, ant colony algorithm, simulated annealing algorithm, etc. [0003] In terms of process planning and layout design of automobile workshops, the following situations exist: [0004] 1) In the process of workshop layout design, on the basis of the basic principles of the layout, the designers and pla...

AI Technical Summary

Problems solved by technology

[0004] 1) In the process of workshop layout design, on the basis of the basic principles of the layout, the designers and planners rely more on the previous layout experience and the work experience of engineers and other related personnel to design the layout qualitatively, which cannot be quantitatively calculated, welded The complexity of the workshop makes the qualitative design more difficult and less reliable;

[0005] 2) In the field of process planning and layout design of the production line, there is a lack of planning and layout ideas for flexible production lines, which makes it difficult to update new models after production, and the replacement of new models will also be difficult;

[0006] 3) The design structure matrix is ​​an analysis and management tool that can be applied to multiple disciplines and aspects. At present, there is almost no research on the application of the design structure matrix to the layout design of the workshop
