چکیده
Failure propagation analysis is the cornerstone to assure safe operation, predicative maintenance for equipment integrated system. Study the failure propagation mechanism of complex system on the basis system directed network constructed. The grade diffusing process widely used is described with the fault propagation probability and constrains. According to the fault information of nodes and edges of network, combined with the probability theory to provide the state transition model with four logic operators are defined to search out all failure propagation paths, the probability of paths are triggered and the most likely failure probability of nodes in different conditions. Finally, compared the results with function space iteration algorithm and show that the method is effectively and rationality in equipment integrated system. Keywords—Equipment integrated system; Fault propagation; Network; State transition equation; Function space iteration

PVT Properties of Pure Lubricants Using Equations of State and Artificial Intelligence
Statistical mechanical and artificial intelligence models are developed to predict the volumetric properties of lubricants under different conditions. It is shown that the knowledge of just liquid density at room temperature is satisfactory to approximate the PVT properties of pure lubricants in various conditions. As well, the performance of an artificial neural network (ANN) based on back pro...
متن کاملAn LPV Approach to Sensor Fault Diagnosis of Robotic Arm
One of the major challenges in robotic arms is to diagnosis sensor fault. To address this challenge, this paper presents an LPV approach. Initially, the dynamics of a two-link manipulator is modelled with a polytopic linear parameter varying structure and then by using a descriptor system approach and a robust design of a suitable unknown input observer by means of pole placement method along w...
متن کاملFault Identification using end-to-end data by imperialist competitive algorithm
Faults in computer networks may result in millions of dollars in cost. Faults in a network need to be localized and repaired to keep the health of the network. Fault management systems are used to keep today’s complex networks running without significant cost, either by using active techniques or passive techniques. In this paper, we propose a novel approach based on imperialist competitive alg...

متن کاملReliability and Performance Evaluation of Fault-aware Routing Methods for Network-on-Chip Architectures (RESEARCH NOTE)
Nowadays, faults and failures are increasing especially in complex systems such as Network-on-Chip (NoC) based Systems-on-a-Chip due to the increasing susceptibility and decreasing feature sizes. On the other hand, fault-tolerant routing algorithms have an evident effect on tolerating permanent faults and improving the reliability of a Network-on-Chip based system. This paper presents reliabili...
