Resource Reallocation Based on Production Scheduling (1st report)-Adoption of Schedule as Index for Resource Allocation-

Abstract

This paper describes a method to improve allocation and re-allocation of resources in manufacturing systems, such as machine tools and robots that are linked by carriers such as AGVs. The proposed method uses the result of scheduling as an index of suitability of the resource allocation. The behaviors of AGV are analyzed and included in the production scheduling problem. The production scheduling problem is solved by employing some well-known dispatching rules. The search for the best scheduling is executed for different assignment of resource allocation, and the suitability of the resource allocation is evaluated based on the schedule obtained. The procedure is repeated to improve the allocation of the resources by applying simulated annealing method. The validity of the proposed method is verified by computational simulations for typical production scheduling problems.
