在多个ES协作系统中不一致性问题的处理

THE PROCESSING OF INCONSISTENCY PROBLEM IN MULTIPLE ESs COOPERATIVE SYSTEMS

在由多个领域相关的ES组成的协作系统中,通常把能独立求解同一个领域难题A的所有ES组成一个协作组。有时组中诸ES对A都给出了相同的断言,但是它们却给出了不同的断言信度值。本文为处理这种不一致性问题,改进了文[1]中的向最高信度值看齐策略和相邻影响策略,提出了向最高权威看齐策略和相互影响策略,并给出了基于模糊 熵、范数和均差值的协作组统一信度值最大偏差的三种计算方法。这些计算方法都是以组中诸信度值不一致性程度的度量为基础的。

In the cooperative systems composed of multiple domain related ESs, ESs which can solve the same one problem A independently, are often organized as a cooperative group. Sometimes, each ES in the group all gives the same assertion to problem A, whereas the CF (Confidence Value) for the assertion is different. In this paper, in order to process this kind of inconsistency problem, we improve the strategies of approaching to the highest CF and adjacent influence, propose the strategies of approaching to the highest authority and interactive influence. Moreover, we also propose three computational methods about the maximum deviation of the united CF of the cooperative group which are the method based on fuzzy entropy, the method based on norm and the method based on mean deviation value. These computational methods are based on the measure about the degree of inconsistency of all CFs in the group.
