Robust Approach for Centralized Job Shop Scheduling : Sequential Flexibility
Year: 2015
Type: article
Abstract: This paper focuses on robust job shop scheduling problems in an evolutionary environment. The schedule is adapted in a reactive manner all along the production process by allowing a sequential flexibility. The adaptations are made in a centralized manner according to a coordination between the decisions taken for all the resources. In the proposed approach, it is assumed that each resource has a flexible local schedule, allowing to handle against unexpected events that occur during the execution. The flexibility arises from the fact that several alternative job sequences are allowed. The global schedule is defined by defining an interval finishing time for each job so as to ensure a consistency between all the local decisions and to keep, if possible, a given level of flexibility. Computational results are reported to show the effectiveness of the proposed approach.
