| 摘 要： | 对经典的离散时间成本平衡问题(DTCTP)模型进行扩展,提出一种多模式资源受限的离散时间成本平衡问题模型.该模型在DTCTP中加入可更新资源约束,通过设定资源价格,将可更新资源与成本对应.为每个项目活动引入压缩执行方式以缩短项目工期.最后提出一种求解该模型的分支定界算法.通过工期底线计算,绘制了一个完整的时间成本曲线,并基于该计算结果讨论了模型的优越性.

| Abstract: | Extending a conventional DTCTP (discrete time-cost trade-off problem) model by introducing the constraint on renewable resources, a new multi-mode resource-constrained DTCTP or MRC-DTCTP model is presented, where the renewable resources are corresponding to project costs by presetting proper resource price and all activities can be executed in a crash mode so as to shorten the time limit originally planned for the project. A branch and bound (B&;B) algorithm for solving MRC-DTCTP model is developed and applied to computing the deadline for the project. According to the computation results, an entire time-cost trade-off curve is plotted and the advantages of the MRC-DTCTP model are discussed. |
