基于动态描述逻辑的网构软件系统故障诊断

Failure Diagnosis of Internetware Systems Using Dynamic Description Logic

提出了一种应用动态描述逻辑对被诊断系统进行分析的方法.动态描述逻辑的语法和语义非常适宜刻画系统的正常行为和异常行为.给出了算法使用动态描述逻辑的可满足性检测来测试离散事件系统的可诊断性.同时,给出了故障诊断器的构造算法.该故障诊断器通过实时地观察系统的行为完成故障诊断.以例子对算法进行了说明.

This paper proposes a way to analyze diagnosed systems using dynamic description logic. Syntax and semantics of dynamic description logic are suitable to describe both the normal and the failed behavior of the system. Then, it gives algorithms to test diagnosability of discrete-event systems by using dynamic description logic satisfiability-checking and for the construction of a diagnoser, which performs diagnostics using on-line observations of the system behavior. Throughout the paper, examples are given for illustration.
