Hierarchical production planning model in flexible job shop including a preemption and sequence-dependent setup times

Abstract

Production planning and control are complex problems for manufacturing organisations. Hierarchical production planning and control is one way to address the problem as it can reduce its complexity and reach good solutions in reasonable computational time. This paper presents a hierarchical approach to resolving production programming in a flexible job shop configuration; this problem includes pre-emption and sequence-dependent setup times. Although non-optimal (as expected), good solutions were obtained as shown in the validation of the method.
