Abstract

Operator allocation is one of the most important decisions that can achieve productivity gains in a labor-intensive manufacturing system. Literature focusing on the operator allocation problem does not consider the difference in operation skill requirement, which is often a constraint for practical applications. This research considered the mixed-skill multi-line operator allocation problem as a mixed integer programming formulation. A case study from Thin Film Transistor Liquid Crystal Display inspection and packaging process is adopted for empirical investigation. The results for the methodology showed promise in solving practical applications.
