Abstract: To balance the workload on a mixed-model assembly line, a novel sequencing model to minimize the number of utility workers was established，the relationship between the space constraints and capacity constraints was analyzed. The space constraints were proved to be a sufficient condition for the capacity constraints. Based on these analyses, the space constraint inequalities with utility workers were presented. To conveniently solve the model, some nonlinear constraints were transformed into linear constraints. Simulation results confirmed the feasibility and validity of this proposed method.
