摘要: 针对有资源约束的项目调度问题模型的不足,调研了企业需求,提出了带有预约时间窗口约束的项目调度模型,并针对该类模型的特点分析了原有算法存在的问题,将分枝定界算法与启发式算法相结合,提出了一种解决该类问题的混合智能算法。仿真结果表明,该算法的优化效果明显优于其他算法。

Abstract: To deal with deficiency of Resource Constrained Project Scheduling Problem (RCPSP) model, a project scheduling model with engaged time windows constraint was proposed after surveying enterprises demands. After analyzing the characteristics of the proposed model and the shortcomings of existing algorithms for model, a hybrid algorithm which combined branch-and-bound procedure and heuristic algorithms was presented. The simulation results demonstrated that the optimization effect of the proposed algorithm was better than other algorithms.

Key words: project scheduling, engaged time window constraint, branch-and-bound algorithm, heuristic algorithm
