When multiple orders are to be processed in a make-to-order environment, scheduling them properly is of paramount importance. Further, it is also important to foresee whether or not the product can be completed in the stipulated time period. In this present work, FlexSim is used to simulate and determine job processing time, waiting time, machine working time, ideal time, etc. Job and machine status reports are then made from the obtained results, and it gives the shopkeeper ample results regarding the job. The simulation results further help in identifying the optimal sequence and in determining the capacity required in all the machining centers for the jobs to meet their respective due dates. If the time required for the job exceeds due date, then capacity is increased and the job is rescheduled again. Even then if it fails to complete in due date, then it is rejected, else accepted.
