效用理论与期望损益值理论在项目风险决策中的比较

Comparison Between Utility Theory and Expected Profit and Loss Theory in the Decision of Project Risk

期望损益值理论是风险决策常用的理论,其决策准则是期望损益值最大;效用理论是在期望损益值理论基础上发展起来的新的决策理论,其决策准则是效用值最大;两者最大的不同是前者不考虑决策者对待风险的态度,而后者则充分考虑决策者对待风险的态度。

Expected profit and loss theory is often used in the decision of project risk. Its criterion is to maximize the expected profit and loss value. Utility theory is a new decision theory, which grows up on the basis of expected profit and loss value theory. Its criterion is to maximize the effectiveness value. The most distinctive difference between the two theories is that the former doesn＇ t consider the policymakers＇ attitude towards risk, and the latter fully considers the policymakers＇ attitude towards risk.
