In general, the scheduling criterion on makespan minimization can effectively shorten the throughput time while the scheduling criterion on total flow time minimization can effectively reduce the WIP. This study attempts to minimize the weighted sum of the abovetwo scheduling criteria in a flowshop environment. Three sub-problems : (1)static scheduling with bicriteria problem in a two-machine flowshop, (2)dynamic scheduling with bicriteria problem in a two-machine flowshop, (3)dynamic scheduling with bicriteria problem in a multi-machine flowshop are tackled in this study. A frozen-event procedure is proposed to transformdynamic scheduling problems into static ones. For each sub- problem, the corresponding heuristic scheduling algorithm is developed. Integer programmingmodels are formulated to validate the performance of those heuristic schedulingalgorithms. Results demonstrate that the proposed algorithms can efficiently solve the flowshop scheduling with bicriteria problems.
