Study Of Bottlenacks Diagnosis And Optimization Of Production Logistics System Of Manufacturing Business

At present with the development of the global economy and technology, customer demand becoming more diverse, the manufacturing mode more and more change which is varieties, medium and small batch production. This makes production logistics system bottlenecks massive existence. And the bottleneck of rare resources is the key to control the production logistics, decided the vast majority of resource utilization degree, as long as the bottleneck of good management of enterprise resources can optimize the systematic logistics and effective output. Therefore, the production logistics system bottlenecks diagnosis and optimizing research is the important means to improve production efficiency, reduce production cost, improve equipment utilization.Production logistics system is a highly complex randomness discrete event system, a traditional method analysis more difficult. Computer simulation is the imitation of the real system, can have large comprehensive correct description of the random factor exists for analysis of complex system. Generally which not easy to deal with uncertainty are particularly effective. There are many advantages for WITNESS as a simulation software compared with other similar software such as friendly interface, model unit rich, interactive object-oriented modeling, real-time animation display, input/output flexibly, model provides software flexibility between data interface, modular modeling, statistical performance parameter dynamic display, etc. Therefore, this article chooses the WITNESS simulation technology and TOC bottleneck constrain theory, one typical combined manufacturing enterprise Shandong Hongyu Machinery Co. processing workshops for example, came to the enterprise manufacturing logistics system, probes into the production logistics system bottlenecks diagnosis and optimization technique.This paper firstly introduces the background of economy and international studies of enterprise production, logistics, analyzes the importance of bottlenecks diagnosis and optimizing of production logistics system research. Secondly, on the basis of previous studies of production logistics system simulation, the WITNESS simulation software is introduced.There are many advantages with the functions and characteristics of the comparison with other simulation software.Thirdly, based on connotation and the characteristic of production logistics system bottlenecks discusses the causes of production logistics system bottlenecks, the approach system bottlenecks diagnosis, control and optimization with simulation technology and TOC technology.Finally, with multiple product small batch typical manufacturing enterprise shandong hongyu machinery Co., LTD as an example to verify the use of computer simulation and TOC production logistics system theory for diagnosis and optimize the bottleneck of the feasibility and advantage, so as to prove the validity and practicability of research results.
