GUPMSP is characterized by the following characteristics: unrelated parallel machine environment, dynamic job arrival, non-preemption, inseparable sequence-dependent setup time, multiple resources requirement, general precedence constraint, and job re-circulation. We proposed the optimization-based schedule generator (OptSG) for the approximation of GUPMSP. Separation of model structure and model configuration in OptSG contributes to the structural independence, which makes OptSG robust and convenient in analysis and problem solving of GUPMSP in real settings with changing properties. Meanwhile, we proposed a mixed-integer-linear-programming (MILP) model for the optimization of GUPMSP. This MILP model was developed as a benchmark to estimate the validity of OptSG. Inseparable sequence-dependent setup time and multiple resources requirement that have not been addressed simultaneously in the literature were considered in the MILP model. Finally, we conducted several experiments to compare the solutions of MILP model, OptSG, and dispatching rule-based heuristics (DRBH). The results validated the practical viability of this study.
