基于战略导向的项目组合选择优化研究

摘要

The paper studies how to maximize the organizational strategic goal through project portfolio selection . We firstly separate the strategic goal to the objective of outcome ,cost and risk, and then integrate the strategic goal to a single trade-off goal with principles of fuzzy cut set and the global criteria methods .This paper develops a project portfolio selection model based on the organizational strategic goal in which trapezoidal fuzzy numbers represent uncertain project parameters and project interactions are taken into account .The model can help organ-ization achieve the consistency of the project portfolio selection and strategic goal .Finally genetic algorithm is presented to solve the model and a case study is provided to illustrate the proposed method .%本文研究了以项目组合的选择实现组织战略目标最大化的问题，将战略目标分解为收益、成本和风险目标，运用模糊集截集原理和目标标准法则把战略目标整合为单个的权衡目标。用梯形模糊数表示项目的不确定参数，并考虑项目间的相互影响关系，建立了基于战略目标的项目组合选择模型，来实现项目组合选择与战略目标的一致。并针对模型提出了遗传算法进行求解，用示例验证了方法的有效性。
