摘要
逆向思维是决策中常用的一种思维方法,但目前的反馈外延决策方法(Decision-making of Feedback Extension,DFE)均未考虑这一点。为此,在因素空间理论基础上,从对立概念角度出发构造了一种概念的外延逼近即反馈外延外包络,在此基础上提出了基于反馈外延外包络的DFE决策方法。通过土壤肥力评级的实例验证了该方法的有效性和可行性。
Reverse thinking is a method widely used in the decision-making, but it is not considered in the existing Decisionmaking of Feedback Extension（DFE）. Therefore, based on the factor space theory, a new extension＇s approximation of concept（outer-enveloping of feedback extension）is constructed in the sight of reverse concept. The DFE decision-making method based on the outer-enveloping is proposed. The method is applied into the evaluation problem of the soil＇s fertile level. The result verifies that this approach is effective and feasible.
