Abstract This research aims to develop a new practical finite capacity material requirement planning (FCMRP) system including a rescheduling method that considers finite capacity of work centers and constraints of suppliers and customers. The five-step algorithm of the system is applied as follows. First, the production and purchasing plans are generated by the variable lead-time MRP system. Second, dispatching rules are applied to prioritize the sequence of jobs and operations. There are two types of dispatching rules, namely, job-based and operation-based rules. Third, all operations are allocated to their first priority work centers by using a sequence from Step 2 with a forward scheduling technique. Fourth, if possible, the tardy operations from Step 3 are moved to their second priority work centers in order to reduce capacity problems on the first priority work centers. This step presents two allocating methods and three shifting options. Last, linear programming is applied to determine the optimal start time of each operation in order to optimize the total cost of the system. The results indicate that all scheduling mechanisms have significant effect on the overall performance index (i.e., total cost of tardiness, inventory holding, work-in-process holding cost) and the proposed FCMRP system can generate a more realistic schedule than the system without supplier and/or customer constraints. The rescheduling function can effectively regenerate new schedules.
