Research on Robustness Scheduling of Prefabricated Components under Uncertain Environment
Based on determining manufacturing technique of prefabricated components and resource constraint,the influence of production scheduling plan of prefabricated components on the robustness value was studied.On the basis of the key chain technology,a centralized buffer schedule considering secondary resource conflicts was constructed,and a two-layer programming model with the shortest production completion time and maximum robustness value as the objective function was established.A nested genetic algorithm is designed to solve the model.Empirical results show that the obtained scheduling plan on the basis of this model has the largest robustness value and is more stable in the face of uncertain environment.
