Research On The Facility Layout Of Workshop Based On Genetic Algorithms

Under the increasing global competition in the fields of manufacture, more and more engineering designer are aware of the importance of the facility layout of workshop in the manufacturing system. The layout design is one of significant factors in many aspects, for instance, it affect the smooth of workshop material flow, the manipulation and servicing of the facilities, the using ratio of workshop area, and it is one of the important factors which affect the production performance of the enterprise. Traditionally, facility layout depends mainly on the experience of the designer and it's qualitative on very big degree, lacking scientific and quantitative description and the measures to it, the cost is high and the cycle is long. This thesis is taking a machining workshop as the object, researching on the optimal model and arithmetic of facility layout, some researches have been made as follows:(1) Make detailed analysis and survey of the facility layout problem, expatiate the basal theory of facility layout.(2) Make detailed analysis on facility layout and production logistics of one machine center workshop, adjust it into hydraulic valve cell and discrete manufacture cell.(3) Divides the facility layout problem into two types, single line layout and lows layout, the optimized models are constructed respectively.(4) Resolve the facility layout model by genetic algorithms, based on single line layout, realize the rows layout of facility with the instruction of automatic newline technology and optimize layout in different dimensions.(5) According to the circs of one workshop, a workshop facility layout management system is developed based on the above workshop facility layout model using Java.The actual facility layout application indicates that the new hybrid solution is much better than traditional methods, it proves that the research has theoretic and practice significance, also the method provides the optimization and layout of the related manufacture workshop with a highly effective and efficient way.
