In order to reduce logistic costs, the scheduling of logistic tasks and resources for fourth party logistics (4PL) is studied. Current scheduling models only consider costs and finish times of each logistic resource or task. Not generally considered are the joint cost and time between two adjacent activities for a resource to process and two sequential activities of a task for two different resources...
The current flow path design models might lead to complicated scheduling and unbalanced bottleneck resources in some cells. A bottleneck resources focused flow path model is proposed in this paper. The number of the ultimate cells and the average load of the bottleneck resources are considered in the model. The proposed model can dynamically form high efficient virtual production cells, balance the...
The flexible job-shop scheduling problem (FJSP) is an extension of the classical job-shop scheduling problem (JSP). This paper presents a hybrid genetic algorithm which incorporates the principle of ldquothe survival of the fittestrdquo from genetic algorithm (GA) into tabu search (TS) to solve the FJSP. According to the characteristics of the FJSP, an extended operation-based representation which...
