USING A LATE‐START RESOURCE‐CONSTRAINED PROJECT SCHEDULE TO IMPROVE PROJECT NET PRESENT VALUE*
提出一种基于关键路径法和物料需求规划的晚开始资源受限项目调度方法，通过大量问题测试发现该方法比早开始启发式调度能获得更高净现值和更短工期。
ABSTRACT Although literature on the achievement of monetary objectives in a resource‐constrained project environment is limited, the maximization of project net present value (NPV) is an important criterion of project success. This paper presents a procedure for developing a late‐start resource‐constrained project schedule using the critical path method‐material requirements planning. Using an extensive set of problems from the literature, we show that this procedure yields a higher NPV and lower average duration than schedules derived with heuristics that schedule each activity as early as possible. In addition, while the late‐start schedule on average was significantly longer than the optimal‐duration resource‐constrained schedule, no significant difference occurred in the average NPVs of the two scheduling methods.
