摘要
工期、成本、质量是工程建设项目的三大控制目标。当前工程管理人员对三大目标的控制相对独立,不能高效地对三大目标进行综合控制。为了更好地解决三大目标之间的协调问题,结合系统可靠性原理,利用二元决策图(Binary Decision Diagram,BDD)对工程项目的整体质量水平进行评价。同时,考虑工程实际的奖罚制度,构建工期-成本-质量综合优化模型并运用非支配近邻免疫算法(Non-dominated Neighbor Immune Algorithm,NNIA)进行求解。运算结果得到了一系列Pareto最优解,验证了所构建模型的可行性及NNIA对求解该模型的有效性。
Project duration,cost and quality are three main objectives of engineering projects. The current controls of the three aspects are relatively independent,which produce the effect in practice is limited. In order to address the issue of coordination among the three objectives better and provide effective decision support for managers,a time- cost- quality trade- off model has been built. In addition the Non- dominated Neighbor Immune Algorithm（ NNIA） has been used to solve the model. The computational result obtained a series of Pareto optimal solution,verifying the feasibility of the model and the effectiveness of NNIA to solve the model.
