The Research On Manufacturing Engineering Layout Based On Discrete Event System Simulation Method

With the advance of science and technology and the growth of social economy, what customers want diversifies, and the life cycle of product is getting shorter and shorter, and the production model of manufacturing industry has undergoes significant change, which shifts from producing a great amount of limited product categories to small quantity of large varieties. This significant change in production model asks for brand new requirements to manufacturing engineering layout,however, the flexibility of lean manufacturing happens to meet these. But due to the complexity of the lean layout, the traditional mathematical modeling method has been difficult to meet the dynamic requirements of the lean layout, therefore, the introduction of application of discrete event system simulation in lean layout which is very important.This dissertation first discourses basic theories of lean production,manufacturing engineering layout and system simulation.Then it analyze the distinctions between traditional layout design and lean layout design,and aiming at the defects and shortages of the traditional layout,this dissertation proposes the research method of lean layout from the practical project.Along with the embodiment of Product-Quantity analysis, process analysis, logistic strength analysis, work station design, human resource and facility allocation, production line layout, system layout planning,simulation and optimizing concrete implementation method. Finally, it analyzes the implementation of lean layout project in D company. Study the manufacturing engineering layout project of D company by Lean concept, with the application of Flexsim simulation software to build up simulation model, output 3D workshop layout model, dynamic output of each period of the data, such as the quantity of WIP, the logistics amount, providing the basis for choosing the best solution by optimizing the parameters through simulation experiment design, achieved good results.The research results prove the validity and feasibility of applying discrete event system simulation in manufacturing engineering layout.
