机械设计专家系统中的不精确推理模型

The Model of Inexact Reasoning of Expert System in Mechanical Design

摘要: 在机械设计决策中,不确定性与模糊性往往是同时存在的。本文将D-S 证据理论推广到模糊集合,并基于此提出一种不精确推理模型用于机械设计的决策之中.

Abstract: In the process of making decision in mechanical design,uncertainty and fuzziness usually exist in common.This paper generalizes Dempster-Shafer theory to fuzzy sets,and based on this generalization,implements a model of inexact reasoning to make decision in mechanical design.
