摘要在项目持续时间的较小变化可能会影响该曲线的几个程序他们假设对活动的成本时间关系进行非现实的简单形式，因此，项目曲线不准确，很少使用，或者它们采用了复杂而不切实际的分析技术。算法的时间成本曲线，因此，算法以平均用户可以理解的步骤进行，并根据减少手动计算和计算机解决方案的范围。该算法的活动持续时间可接受的值可根据需要在不同的项目持续时间内产生最佳或成本危险计划。
AbstractThe development and use of the time-cost trade-off curve for a project is an essential part of a CPM analysis, since small variations in project duration could heavily affect the project’s cash flow. Several procedures exist for developing this curve. However, either they assume un-realistically simplified forms for the cost-time relations of the activities, whereupon the project curve is inaccurate and of little use, or they employ complex and impractical analytical techniques. This paper suggests a simple and efficient computational algorithm for developing the project time-cost curve for arbitrary, and thus realistic, cost-time relations for the activities. The algorithm proceeds in steps understandable by the average user and it is suitable for both hand calculations and computer solutions. Based on a scheme for reducing the ranges of acceptable values for activities durations, the algorithm produces either optimal or cost-satisficing plans, as desired, for different project durations.
