مقاله A Discrete Particle Swarm Optimization to Minimize MaximumTardiness with Batch Delivery and Job Release Times
چکیده مقاله:
Due to high delivery costs, manufactures are usually required to dispatch their jobs as batches. This, however, causes some crucial problems in scheduling-related objective functions such as minimizing maximum tardiness. The current paper addresses scheduling a set of jobs with specified release times that are to be processed in a single machine and dispatched to customers or other machines in a batched delivery system. Each batch has a particular delivery cost. The aim is to minimize maximum tardiness plus delivery costs. This is an NP-hard problem. A mathematical model is proposed and solved by a commercial solver. However, such model shows low efficiency in large size problems, so a discrete particle swarm optimization (DPSO) algorithm is developed. Finally, computational results obtained from observations of the DPSO algorithm is provided for some randomly-generated problems.
