Expected value model of production schedule by considering robustness constraints
考虑鲁棒性的生产调度期望值模型

Stochastic phenomenon is prevalent in production processes, but expected value model cannot ensure the robustness. Based on the chance constraints programming, the sufficient conditions according to two different kind of probability distribution of the stochastic parameters are proposed and proved in this paper, under which the feasible solutions can satisfy the robust index. The robustness constraints are then constructed to contract the feasible region and improve the robustness of expected value model. Finally, the simulation results illustrate the validity of the improved model.
