A Model of Makespan Flow-Shop Scheduling Under Ergonomic Requirements
This paper address the recent growing interest the industrial environment has put over the healthy work. The ergonomics studies worker’s fatigue and muscular stress risks. It shows the need to measure and evaluate risks to improve the efficiency and reduce the costs. Based on a literature review from the scheduling and ergonomics point of view implications are highlighted. The paper presents a MILP mathematical model to minimize makespan in an n-job flow shop problem with sequence dependent setup times considering recovery times.
