Study On Large Facilities Layout Using Logistics Rationalization

Since the 1950s, China has established a number of large industrial and mining enterprises. In the choice of the locations of these factory and internal facility layout, they still used in the former Soviet Union design method, which is based on technology used for centuries in various industries factories accumulated experience, lessons data and information on the location of factories and workshops throughout the region for plant layout, layout of the main qualitative. In China's major design institutes the factory facilities layout still widely used traditional methods layout experience. However, as the develops of systems engineering, computer technology and other disciplines, because of the lack of quantitative analysis of the traditional design methods, it hardly combines with modern computer rapid design technology, the slow design process , heavy workload, lack of convincing and a series of programs gradually become an issue out. These issues are in question of design institute. In this issue, not only to affirm with the advantage of traditional method, but also to raise a method with the systematic quantitative analysis and the traditional design method. The purpose of this issue is not only to make factory facilities planning with quantitative analysis and optimization, but also make the project more practical workability, and can be used in design examples.This issue introduced the origin and development of logistics and factory logistics, and on this basis, analysis the research and characteristics of factory logistics, proposed the research goal of factory logistics is to rationalize the logistics, summed up the channels of factory logistics rationalization from the perspective of enterprises facilities planning.This issue takes factory facilities as research object and factory logistics rationalization as research aim, has established mathematical model separately about the major production facilities layout and auxiliary production facilities layout. The model is established from the start with the rationalization of logistics factory, with the specific shape and export location of production facilities and the type of auxiliary production facilities, detailed description of the process of factory facilities choice of location in theoretically.Meanwhile it has also made the analysis to the factory facilities qualitative planning, and has obtained the research methods of combining traditional method with systematic quantitative analysis method. This method can propose the facilities layout program quickly and efficiently while minimizing the logistics costs of the factory.As to factory materials transport planning, this issue takes factory material transportation materials as research object, and enterprise logistics rationalization as research aim, has established mathematical model of the factory materials transport mode choice and factory material transit route choice, which based on qualitative analysis of various transport modes. And based on the characteristics of the factory materials transport, it carries on the organization and optimization of factory production materials transport.Finally, sum up the relations between factory facilities layout and material transport, we can obtain the conclusions that in order to achieve factory logistics rationalization, the good facility layout and the reasonable materials transportation systems should unify.
