Assembly And Test Workshop Of Communication Equipment Facility Layout Research

Since the1980s, pushed by the global information technology revolution, communication equipment manufacturing industry has gradually become one of the most promising high and new technology industries, which has the biggest potential market and fastest growing speed. But with the continuous technology innovation, the initial high value-added fort slowly disappeared. Corporations must reduce operation costs in order to survive in the contemporary competitive economic circumstance. The cost of materials processing gradually emerged as the key factor which influenced the continuously cost reduction. The costs reduction of materials processing can be achieved through effective optimization of workshop layout, and effective design of equipments and facilities layout can do a good favor to it.This project mainly have done some research about the optimization of communication manufacturing equipment layout for assembly and test workshop. Technology innovated fast, enormous capital invested for production research and development, and product renewed fast in communication industry. Therefor the newly imported production often promoted the facilities layout. More than often, enterprises never relied on the layout optimization theory, nor on modeling optimization or simulation ability. Oppositely completed on related experience, which had serious blindness and limitations, failing to predict the effect after improving actions. Enterprise would have be apt to fall into a trap of which the improvement would take a long time and have poor effects. This paper aimed to provide a set of simple, feasible, and convenient and practical equipment layout method, for similar communication manufacturing enterprise.In this paper, the author have researched on the theory of systematic layout planning, the theory of particle swarm optimization and so on, combined with modern computer technology. Then analyzed plant equipment layout optimization problem. Then the author combined the actual situation of an enterprise workshop equipment layout to carry out application study. Analysed expected material handling quantity, compared various process comprehensive close degree based on systematic layout planning method. Then according to the various modifications views and practical restrictions, we can draw different facilities planning schemes. Then established the multiple columns layout model of unequal area facilities. Facilities planning scheme was substituted into the model as the initial value, combining with particle swarm optimization to solve the problem of continuous space facility layout optimization.This paper research key:first of all, used two dimension vector to express equipment continuous space position during modeling; Then introduced the scheme of systematic layout planning to Particle swarm optimization, and improved algorithm of optimal speed and accuracy on the bases of ensuring the the effectiveness of the initial particle swarm; Finally improved the PSO algorithm of optimal quality through setting the acceleration coefficient and inertia coefficient. Examples verified the effectiveness of the proposed method can effectively improve the optimization performance of PSO algorithm in continuous space layout problem.This paper combined PSO algorithm and the systematic layout planning which can realized layout optimization of the multispecies and small batch production mode workshop. This method is suitable for workshop equipment layout optimization of the communication equipment manufacturing enterprises, before the production of the new products.
