Abstract: The Job shop scheduling problems with stochastic processing times under machine-worker dual resource constraints is studied. Considering the difference in worker proficiency and the insufficient number of workers, a robust scheduling approach is adopted, and then the machine-worker dual-resource constrained robust Job shop scheduling problems model (DR-RJSSP) is formulated. Because of the requirements of DR-RJSSP for workers' rational assignment and bi-objective optimization, a heuristic based on a two-stage assignment strategy is proposed, which can minimize the random disturbances of the processing times as well as its impact on scheduling efficiency. Thereafter, a multi-objective hybrid estimation of distribution algorithm is employed to solve the DR-RJSSP. Thereby, the solution set considers both the performance and the robustness of the schedule can be obtained. At last, the proposed two-stage assignment strategy(TSAS) is compared with the proficiency-based assignment strategy as well as the machine-worker randomly assigned strategy through simulation experiments. Finally, eight standard instances and a problem instance obtained from a manufacturing company are employed. According to the simulation results, the Pareto optimization performance of the proposed TSAS and its effectiveness to solve the Job shop scheduling problem of the actual manufacturing system are verified.
