Abstract: The resources scheduled affect the profit of MRO (maintenance,refair and overhaul) service companies directly. From the perspectives of MRO service provider, an optimization scheduling problem of multi-skilled workforce working was studied for customers distributed in different locations. Considering workforce travel cost and time cost, a multi-skilled workforce scheduling optimization model was established to get the minimum total workforce cost, which is an integer nonlinear programming model. According to the characteristics of integer variables, the model was linearized, and solved by means of ILOG CPLEX. Through a large number of simulation experiments with different parameters, the validity of the model was verified.

Key words: MRO (maintenance, refair and overhaul), service center, multi-skilled workforce, scheduling, nonlinear integer programming
