Heuristic methods to consider rest allowance into assembly balancing problem

Abstract

This study incorporates human energy expenditure and the related rest allowance into a SALBP-2. During last years, the impact of human factors on the assembly line design has grown up and ergonomic restrictions, worker skills, physical and psychological conditions have been considered in the assembly balancing. In this work, the human energy expenditure is applied. For this purpose, three heuristic methods are here proposed and compared in order to underline the effect of rest allowance in the balancing problem. A numerical example is used to show and discuss the differences between the three methods.
