We consider a real-world machine grouping and layout problem in which the objective is not onJy to identify machine cells and corresponding part families' but also to determine a near-optimal layout of machines within each cell and the cells themselves. The three-stage approach developed incorporates materials flow considerations while determining machine groups, considers alternative process plans, exploits part routing information and allows the user to perform sensitivity analysis. The menu-driven, interactive program has been applied to four test problems and an industrial problem. OUf experience with applying the approach to the industrial problem is also reported.
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.
