A group layout design model of a dynamic cellular manufacturing system

This paper presents a novel mixed-integer nonlinear programming model for the group layout (GL) design of a dynamic cellular manufacturing system (DCMS). A novel aspect of this model is concurrently making the cell formation (CF) and GL decisions in a dynamic environment. Another compromising aspect of this model is the utilization of multi-rows layout to locate machines in the cells configured with flexible shapes. The proposed model incorporates several design features including alternate process routings, operation sequence, processing time, production volume of parts, purchasing machine, duplicate machines, machine capacity, lot splitting, group layout, multi-rows layout of equal area facilities, and flexible reconfiguration. A numerical example taken from the literature is solved by the Lingo software to illustrate the performance of this model.
