Abstract

This study first investigated the problem of scheduling the wagons in facilities for maintenance with the objective of minimising the time required to remanufacture the train. Accordingly, a mixed integer linear programming (MILP) formulation was implemented with the Makespan as an objective. The MILP model can only be applied to industrial cases that involve few operations. Therefore, to cope with these cases, we show that the problem is an extension of a flexible job shop (system) scheduling problem and propose a heuristic method based on job insertion and Johnson rules to solve a large set of instances. This study then determines the optimal quantity of resources to be dedicated to each facility as a function of the Makespan threshold value. Thus, an optimisation method based on an evolutionary algorithm is designed. This metaheuristic provides the minimum quantity of resources to be dedicated to each facility as a function of the Makespan threshold value. [Submitted: 29 January 2024; Accepted: 4 September 2024]
