扩展模糊时间Petri网的定义和性质

Extended Fuzzy Timed Petri Net Definitions and Properties

随着装备的复杂程度不断地提高,对装备的故障诊断难度也不断加大,容易出现故障原因漏判的现象。为解决此问题,文章在模糊时间Petri网的基础上,通过在库所和变迁中引入模糊时间戳对其进行扩展,建立扩展模糊时间Petri网模型,并给出相关计算和运行实例。

The fault diagnosis of equipment becomes more and more difficult while the equipment become more and more complicated. So it happens easily that some causes are missed during fault diagnosis which is called cause-missed problem in this paper. To resolve this problem, some tasks were done in this paper. A model was defined in this paper, which called Extended Fuzzy Timed Petri Nets （EFTPN） and extended the model which called Fuzzy Timed Petri Nets （FTPN） by adding a fuzzy timed factor to place and translation. An example and some calculations are given in this paper also.
