本文采用0—1线性规划数学模型,以投资系统的净效益现值作为目标函数,考虑社会需求和资源供应的约束条件,提出了投资项目选择的系统论证方法,并编制了电算程序。通过山西省水利投资项目选择的计算分析,说明该方法和程序比较接近实际,是有效的。
In this paper, 0-1 linear programming mathematical model is used to present the present value of the net benefits of investment system as an objective function. Considering the constraints of social needs and resource supply, a systematic demonstration method of investment project selection is proposed and a computer program is compiled. Through the calculation and analysis of Shanxi Province water conservancy investment project selection, it shows that the method and procedure are more realistic and effective.
