不确定收益下关键链项目缓冲前置分配模型

在关键链项目管理技术中,缓冲的设置和监控是决定项目计划稳定性和有效性的关键一环.但现有的理论对项目缓冲的分配却没有一个清晰的界定.由于工序在执行时具备可延迟的特性,我们把实物期权的思想引入项目缓冲的分配过程中,通过将缓冲区前置,设计不确定性的概率分布来建立一个基于实物期权的0-1整数规划模型.将关键链管理思想和最迟开工规则有机结合,使得时间缓冲能够在各个关键工序中的灵活分配,实现关键链项目管理期权价值最大化.

The Study of Project Buffer Prepositive Allocation for Uncertain Incom in Critical Chain Management

The management of project buffer in critical chain is the key factor to achieve the satisfying condition for project schedule.But there is not a legible and reasonable method to distribute the project buffer.This paper incorporates real options concepts to construct an option-based 0-1 integer programming model considering the probability distribution of uncertainty to allocate the prepositive project buffer among critical activities.Using the model,we such activities with time flexibility can be executed a...
