Abstract
ABSTRACTIn order to solve the problems associated with the organization of the dynamic facility layout in a manufacturing workshop, utilizing a chaotic generic algorithm with improved Tent mapping is proposed as a solution. The tent map is used to generate the initial population which is distributed throughout the solution space. Excellent individuals have the Genetic Algorithm optimization with elitist strategy applied to them. Partially matched crossover and mutation operations for single-period-layout encoding string are executed, and adaptive chaotic disturbance is increased to the superior individual. This method is an important innovation in the field of layout optimization by chaotic genetic algorithm. Finally, the paper compares several algorithms by analyzing sample outcomes of their respective implementations. It is also more convenient to verify the T-CGA method, which is better than the traditional method in solving the accuracy and the efficiency.
Highlights
The change in market demand has forced the enterprises to adopt a more flexible production mode in order to stay competitive
The traditional static facility layout, which does not consider the dynamic characteristics of the market, is more costly and can hardly satisfy the requirements of the enterprise
Hosseini-Nasab and Emami (2013) proposed the use of a hybrid particle swarm algorithm to solve the problem by coding and decoding method specially applied to DFLP
Summary
The change in market demand has forced the enterprises to adopt a more flexible production mode in order to stay competitive. This flexibility should be established across different varieties, large, many few varieties and small batches. In this case, new equipment acquisition, shop layout adjustment or reconstruction inevitably become more frequent. The traditional static facility layout, which does not consider the dynamic characteristics of the market, is more costly and can hardly satisfy the requirements of the enterprise. It is imperative to study the dynamic facility layout problem. The study of the problem has important theoretical significance and practical value in engineering
