针对当前工程项目网络计划制定中难以对工期、成本、质量三大目标进行有效统筹管控的问题.将这三大目标转化为增量净收益目标,解决由于各单目标之间量纲的不同而难以统筹优化问题,建立了增量净收益最大的工期-费用-质量模型,理清了它们之间错综复杂的关系和相互对立的局面.充分利用差异演化算法和粒子群算法的各自优点,提出了差异演化粒子群算法对上述多目标优化模型进行求解;并通过工程实例检验差异演化粒子群算法的有效性,计算结果显示,改进算法在很大程度上改善了求解性能,极大地提高了工程项目的净收益.
針對噹前工程項目網絡計劃製定中難以對工期、成本、質量三大目標進行有效統籌管控的問題.將這三大目標轉化為增量淨收益目標,解決由于各單目標之間量綱的不同而難以統籌優化問題,建立瞭增量淨收益最大的工期-費用-質量模型,理清瞭它們之間錯綜複雜的關繫和相互對立的跼麵.充分利用差異縯化算法和粒子群算法的各自優點,提齣瞭差異縯化粒子群算法對上述多目標優化模型進行求解;併通過工程實例檢驗差異縯化粒子群算法的有效性,計算結果顯示,改進算法在很大程度上改善瞭求解性能,極大地提高瞭工程項目的淨收益.

@@@@Time limit,cost and quality for an construction project can be thought as three opposite and unified control objectives of project management. It is difficult to co-ordinate control in the setting of network planning. This paper constructs the maximum incremental net benefit of time-cost-quality into which the three big unified and opposite goals of the time limit,cost and quality for a project can be changed. And the model avoids the contradictory situation between them and the dimensional difference. The model has sort out the complicated relationships between them and contradictory situation. Due to the complexity of implicit constraints in the model which brings bigger difficulties to solve the model,the model can be solved combined with the differential evolution algorithm and particle swarm algorithm advantages. Finally,the validity of the algorithm has been proved through a construction example. Solving performance has been improved and net benefit of construction project has been improved.
