MODEL MULTIOBJECTIVE FLEXIBLE JOB SHOP SCHEDULING WITH BATCH PROCESS

To compete in business competition, each manufacture must be able to fulfill the consument demand precisely, While considering its lack of resource in terms of the amount of machine and the capacity of machine in processing each job. Scheduling is needed to assure the efficiency of the resource. Flexible job shop is a branch of scheduling which is the extension of Job Shop, it allows an operation to be processed by a set of machine instead of one machine. This research will develop the model of Flexible Job Shop Scheduling with multiple objective function, that is makespan and tardiness. This research is also considering the batch process, which allow some machine to have multiple capacity so it can process more than one job simultaneously.
