Emergencies such as machine breakdowns and rush orders greatly affect the production activities of manufacturing enterprises. How to deal with rescheduling problem after emergencies have high practical value. Meanwhile, under background intelligent manufacturing, automatic guided vehicles are gradually emerging in To disturbances flexible job shop scheduling vehicle transportation, a mixed-inte...

In this paper a new neuro-genetic architecture is presented that solves a profit oriented dynamic job shop problem. In the job shop order acceptance and scheduling problem new jobs arrive continuously and because of insufficient job shop capacity, a selection has to be made among the offered jobs. The goal is to find an order acceptance policy, which is supported by a scheduling policy, that ma...

For the purpose of solving the flexible job-shop scheduling problem (FJSP), an improved quantum genetic algorithm based on earliness/tardiness penalty coefficient is proposed in this paper. For minimizing the completion time and the job-shop cost, a simulation model was established firstly. Next, according to the characteristics of the due in production, a double penalty coefficient was designe...

proper scheduling of tasks leads to optimum using of time and resources, inorder to obtaining best result. one of the most important and complicatedscheduling problems is open shop scheduling problem. there are n jobs in openshop scheduling problem which should be processed by m machines. purpose ofscheduling open shop problem is attaining to a suitable order of processing jobs byspecified mach...

To improve the management of collaborative manufacturing tasks in MES and promote digital transformation discrete enterprises, based on has been studied. First, business flow an was analyzed systematically. Second, algorithm detailed scheduling for studied, a model external resources designed. Then, solution presented hybrid genetic algorithm. Finally, execution process promoted integration ERP...

The Flexible Job Shop problem is a generalization of the classical job shop scheduling problem in which for every operation there is a group of machines that can process it. The problem is to assign operations to machines and to order the operations on the machines so that the operations can be processed in the smallest amount of time. This models a wide variety of problems encountered in real ...
