Abstract: It is difficult to control the mould workshop production effectively. To deal with this problem, a multi-level job release control model was proposed. Firstly, considering the uncertainties of the task durations and resource requirements, release strategies were analyzed. And the calculation approach of the direct and indirect workload of load centers was established. Then, from the perspective of the overload problems in the load centers, capacity adjustment strategies were analyzed. Furthermore, optimization model was constructed for selecting the subcontracting jobs. And hybrid optimization algorithm was designed to solve the optimization problem. Finally, an application example demonstrated the practicability of the approach.
