基于因素空间反馈外延外包络的DFE决策

摘要

Reverse thinking is a method widely used in the decision-making, but it is not considered in the existing Decision-making 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.%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 Exten-sion，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。
