A concurrent approach to cell formation and assignment of identical machines in group technology

A simulation-based evolutionary multiobjective approach to manufacturing cell formation

“…The solution fitness evaluations were performed via a simulation of Table 6 Operation processing times (min). Adapted from Wu (1998).…”

“…Fig. 17 exhibits the solution obtained by Wu (1998) for this problem instance and solution 5 from Table 9. They are represented in the design space.…”

“…This example is an adaptation of a problem instance presented by Wu (1998). It is composed of 13 machine types and 13 part types.…”

“…They considered explicitly the existence of multiple copies of machines and alternate routings. Wu (1998) proposed a graph-theoretic approach which is capable of representing replicate machines. Appropriate solutions were generated with the assignment of replicate machines to different cells, with the objective of minimizing intercell flows.…”

Comprehensive grouping efficacy: A new measure for evaluating block-diagonal forms in group technology

“…The main idea of GT is to capitalize on similar manufacturing processes and features where similar parts are grouped into a part family and manufactured by a cluster of dissimilar machines (Wu, 1998). The input to the GT problem is a zero-one matrix A where aij = 1 indicates the visit of component j to machine i, and aij = 0 otherwise.…”
