Titre: Identical Parallel Machine Scheduling with the Promise of Maximum Waiting Time for an Emergency Job

Résumé:

Currently, customer satisfaction plays a more and more vital role in both manufacturing and service industry. Promise of an acceptable waiting time for customers has been considered as an effective approach to improve the customer satisfaction. In this study, an identical parallel machine scheduling problem with the promise of maximum waiting time for an emergency job is investigated. A mixed integer programming enhanced with symmetry-breaking constraints is formulated. Two objectives, makespan and total completion time, are considered separately. For the case of makespan, the worst-case approximation ratios of classical heuristic rules are deduced. For the case of total completion time, efficient bounds are provided and the NP-hardness of the problem is proved. Heuristic methods based on the classical dispatch rules are developed for both cases. Extensive computational experiments are conducted, through which the performance of the formulation and heuristics are compared, the relationship between objective values and the promised maximum waiting time for an emergency job are explored, and some observations and managerial insights are obtained.
