摘 要:在研究由业主和建筑商组成的两级建筑供应链的工期协调优化问题时,首先建立了基于网络图的具有资源约束的传统工期费用交换问题的优化模型。针对传统工期优化模型的缺陷,建立了具有固定资源约束的考虑资金时间价值的工期优化模型。然后从供应链角度,考虑供应链成员决策的相互影响,建立了具有柔性资源约束的基于工期奖惩机制的工期协调优化模型。给出了模型的求解算法。最后结合算例对比了不同工期优化下的结果。结果显示,传统工期优化模型的优化结果很难在考虑资金时间价值的模型中实现,但通过奖惩激励可以实现甚至更进一步改进工期优化结果,同时实现项目工期控制目标协调优化和供应链的帕累托改善。In order to study the coordination and optimization of project duration in the two-level construction supply chain, which is constituted by the owner and the contractor, the optimization model of traditional time-cost trade-off is built based on Activity-on-Arc network firstly. Aiming to the defects of traditional project duration optimization model, the dynamic project duration optimization model with fixed-resource-constrained is formed by considering the time value of capital. The mathematic model of project duration coordination and optimization in construction supply chain, is further proposed by considering the decision interaction between the owner and the contractor in the viewpoint of the whole supply chain, which is based on flexible-resource-constrained and bonus-penalty mechanism, considering the time value of capital. In addition, the solution algorithm of each model is given. Finally, the models are illustrated by an example. The results show that the outcomes of the traditional project duration optimization model are hard to be achieved in dynamic project duration optimization model, while it can be improved in the proposed model with bonus-penalty incentive. The proposed model can actualize the optimization of project duration coordination and Pareto improvement of construction supply chain as well.
