RESUMO

Group tecnology techniques are now widely used in many manufacturing systems. Severla algorithms have been proposed for the optimal design of efficient manufacturing cells. The cell formation problem must take into account several objectives: the number of bottleneck operations, the number of bottleneck machines and/or parts, the intercell flow, the intracell workload balancing, the subcontracting cost, the machine duplication costs, and the workload of the busiest machine and/or cell, among athers. In this work, we propose a multi-criteria methodology for solving the cell formation problem with multiple objectives. This approach is based on the use of the tabu search meta-heuristic for solving a sequence of single-objective, multi-contrained problems, in wich each objective is taken and optimized in turn, following their order of relative importance. Computational results concerning an application to a bi-criteria problem are reported for instances with up 100 machines and 1000 parts.
