Study on disruption management scheduling problem of flow shop under supply chain environment

Abstract

Abstract. This paper presents a disruption scheduling model for an environment of proportional two-machine no-wait flow shop. To achieve the objects of minimization of weighted sum of makespan and minimization of weighted sum of tardiness, we introduce a revised PSO algorithm which is designed with a neighborhood search structure. According to the experiment, the effectivity of the method proposed is proven.

Disruption management-based coordinated scheduling for vessels and ship loaders in bulk ports

“…To reflect the rationality of the new scheme and the difference between the new scheme and the initial scheme comprehensively, [33][34][35][36][37] are referred to use the generalized cost as the objective function, including the cost of implementing the new scheme and the penalty cost of adjusting the initial scheme. In addition, the hard constraints in the model have to be satisfied, while the soft constraints will be satisfied to the greatest possible extent.…”
