考虑支付进度的动态工期优化
发布时间：2019-04-10 08:51
【摘要】：建立了基于网络图的传统工期费用交换问题的优化模型。针对传统优化模型的缺陷,考虑资金的时间价值,以净现值最大化为优化目标,建立了基于工程款支付进度的动态工期优化模型,目标函数包括了项目实施中的各项现金流入和流出:业主支付、活动直接费用、项目间接费用。同时给出了两个模型的求解算法。最后结合一个算例对比了不同工期优化下的结果。结果表明,与传统优化模型相比,虽然本文提出的优化模型工期增加了,但建筑商的净现值收益提高了。从反映建筑商真实收益的净现值角度看,所提的模型更优。
[Abstract]:The optimization model of traditional project cost exchange problem based on network diagram is established. Aiming at the defects of the traditional optimization model, considering the time value of the funds and taking the maximization of the net present value as the optimization goal, a dynamic time limit optimization model based on the payment schedule of the project is established. Objective function includes cash inflow and outflow in project implementation: owner's payment, activity direct cost, project indirect cost. At the same time, the algorithm of solving the two models is given. Finally, a numerical example is used to compare the results under different time limit optimization. The results show that compared with the traditional optimization model, the time limit of the optimization model proposed in this paper increases, but the net present value income of the builders increases. From the point of view of the net present value which reflects the real income of the builder, the proposed model is better.
