对“资本限量决策”方法的改进

Improving on the Method of Capital Rationing Decision

企业面临的一类投资决策是所谓的资本限量决策,文献1给出两种解法:获利指数法和净现值法。究其实质,净现值法是一种枚举法或互斥化法,该方法可以获得最优解,但当项目个数较多时,互斥化的组合方案数很大,难以实用;计算加权获利指数工作量又很大。本文提出用差量效率指标排序法予以改进。

Capital rationing decision is a common problem enterprises confront. This article, which dissects profits index method and NPV method in 1^st conference, considers that NPV method, actually as an enumerating method or mutually excluding method, can find optimal solution, but it is difficult to apply to plenty of mutually exclusive combination, and that it is eomplicated to calculate profits index, it offers an appropriate method that is ordering of efficiency minus index method to improve it.
