Presents a new design methodology and an integrated approach for the design of manufacturing systems. The methodology discusses the steps leading to design of manufacturing systems; the integrated approach suggests ways of integrating the different stages of manufacturing system design using genetic algorithms. The methodology and approach has been used for an industrial case study and the result has shown that the approach is effective.
This paper presents a design methodology and a genetic algorithm-based approach for redesign of a manufacturing system for a small steel pre-fabricated building manufacturer. Through the application of celular manufacturing principles, we discuss the application of the design methodology that takes a topdown approach to determine system needs and a bottom-up integrated design approach to develop the con® gurations of the manufacturing system. The integrated design approach uses a genetic algorithm and an AutoCAD interface to minimize the inter and intra cell material movements during cell formation. A selected set of solutions obtained are further analysed using discrete event modelling and simulation. The ® nal results presented indicate a substantial improvement in overall performance compared to the original layout. The company has implemented a modi® ed version of the ® nal solution and has achieved the signi® cant improvements in material handling and overall productivity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
