JOB SCHEDULE IN FLEXIBLE MANUFACTURING SYSTEMS USING AGGREGATED MODELS

Effective schedule of production operations that conducts to optimized solutions that are realistic and feasible is a complex task that has been intensively studied due to its economic importance. Starting from the graph of the detailed problem, a method of optimization the task schedule is emphasized. In order to obtain a minimum time for the project execution together the fulfilment of resource constraints, the detailed model is aggregated, optimized from the point of view of the graph height and cardinality and finally the solution is disaggregated. The method is applied in the case study of a Flexible Manufacturing System for an assembly project that is used for educational purposes, emphasizing the results.
