考虑多因素的可打断项目组合选择模型研究

摘要

Based on the existing research on divisible project portfolio selection problem, in this paper we tahe interdependency,divisibility and resource constraints into account,with the objective of maximizing the net pres-ent value of the selected project portfolio,and the divisible project portfolio selection model considering multiple factors is built for the first time.Meanwhile, according to whether consider divisibility, interdependency and resource constraints,three project portfolio selection models are constructed.All the models are solved by GAMSBARON,and the results show:1)resource constraints are the hey factors in the project portfolio selection prob-lem with divisibility to determine the success or failure of the project portfolio selection;2)unlihe the research of the past,project divisibility can increase the income of the enterprise under the resource constraints;3)when the interdependency among the projects is considered,reasonable project portfolio selection can mahe the enterprise get,when collaborative benefits outweigh the loss of competition.%本文在已有可打断项目组合选择模型研究的基础上,同时考虑了资源约束,项目间的相互依赖关系以及项目的可打断性这三种因素,以净现值最大化为目标,首次构建了考虑多因素的可打断项目组合选择模型.此外,根据是否考虑资源约束、项目间的相互依赖关系以及项目的可打断性,分别构建了不同情形下的三个模型.最后给出算例,并运用GAMSBARON求解,结果表明:1)资源约束是可打断项目组合选择的关键因素,关系着项目组合选择的成败;2)资源约束下,通过项目打断执行可以增加收益,这有别于已有的研究;3)考虑相互依赖关系时,合理进行项目组合选择使协同利益大于竞争损失,能使企业获利更多.
