Abstract:

This study investigates the performance of order-input sequencing heuristics in a cellular flexible assembly system (CFAS) by computer simulation. The CFAS produces low-volume, large products in an assemble-to-order environment. This study examines two types of heuristic: two-stage (group scheduling) heuristics and single-stage heuristics. Two-stage heuristics attempt to serially process similar orders and eliminate major setups required between subfamilies. The results of the paired t-test analysis show that the two-stage heuristics outperform the single-stage heuristics under each experimental condition for various measures. The superior performance of the two-stage heuristics is due to the reduction in major setup times. The simulation results can provide guidance for schedulers in the selection of preferable heuristics for relevant CFASs.
