财务约束条件下项目投资组合决策研究--基于可信性理论的投资组合决策解决方案

Stduy on Decision-making Plan of Project Portfolio under the Capital Restriction:A Solution for Portfolio Decision Making Based on Credibility Theory

近年来,基础设施投资项目的资金约束明显收紧,尤其是项目资本金成为项目投资的刚性约束。企业在面对众多可选项目时,如何优化项目组合的结构,做出项目组合收益最大的决策,已成为基础设施项目投资企业的重大课题。考虑投资项目组合的财务约束条件,优化既有投资组合模型,构建能够满足企业实际需要的投资组合模型,应用遗传算法对模型求解,为企业项目投资决策提供解决方案,并对模型进行实证分析。

In recent years,the capital restriction of infrastructure project is obviously tightened,especially the project capital becomes the rigid restriction of project investment.In the new conditions,it becomes a problem that how to select the optimal projects to optimize the structure of the project portfolio,and improve the overall income level.This paper improves the existed portfolio model and constructs a new portfolio model that can meet the needs to solve this problem,then uses genetic algorithm to solve the model and makes an empirical study on this model.
