电力企业投资决策模型的密切值法

Close Value Method for Electric Power Enterprise Investment Decision Model

针对电力企业投资决策问题,提出了一种基于灰靶决策的密切值法,克服了传统的灰靶决策模型只考虑正靶心距对方案进行排序不考虑负靶心距对决策的影响。并采用变异系数法客观地确定指标权重,避免了以往主观权重确定法的随意性。最后,通过某电力企业投资方案选择问题作为实例说明本文所提出的方法的实用性和有效性。

Aiming at the electric power enterprise investment decision problem,a new decision method is proposed based on the grey target decision, named close value method, which can reflect the alternative plan is close to the bulrs-eye and away from the close value minus the bull ＇s-eye, overcomes the traditional grey target decision model of sorting scheme only consider is distance to target＇s influence on the decisions without considering the negative distance to target. And the variation coefficient method is used to objectively determine the index weight, avoid the arbitrariness of previous subjective weight determination. Finally, the electric power enterprise investment selection problem is given to illustrate the practicability and effectiveness of the decision making process.
