Edge Device Fault Probability Based Intelligent Calculations for Fault Probability of Smart Systems

Tsinghua Science and Technology 2024年第4期29卷 1023-1036页

作者： Shasha Li Tiejun {1. Wattana Viriyasitavat School of Environmental and Chemical Engineering Shenyang Ligong UniversityShenyang 110159China Chulalongkorn Business School Faculty of Commerce and AccountancyChulalongkorn UniversityBangkok 10900Thailand

In a smart system, the faults of edge devices directly impact the system’s overall fault. Further, complexity arises when different edge devices provide varying fault data. To study the Smart System Fault Evolution Process (SSFEP) under different fault data conditions, an intelligent method for determining the Smart System Fault Probability (SSFP) is proposed. The data types provided by edge devices include the following: (1. only known edge device fault probability;(2) known Edge Device Fault Probability Distribution (EDFPD);(3) known edge device fault number and EDFPD;(4) known factor state of the edge device fault and EDFPD. Moreover, decision methods are proposed for each data case. Transfer Probability (TP) is divided into Continuity Transfer Probability (CTP) and Filterability Transfer Probability (FTP). CTP asserts that a Cause Event (CE) must lead to a Result Event (RE), while FTP requires CF probability to exceed a threshold before RF occurs. These probabilities are used to calculate SSFP. This paper introduces a decision method using the information diffusion principle for low-data SSFP determination, along with an improved method. The method is based on space fault network theory, abstracting SSFEP into a System Fault Evolution Process (SFEP) for research purposes.
