Fault Propagation Using Fuzzy Cognitive Maps
نویسنده
چکیده
An algorithm is presented for propagating the effect of single or multiple faults in a system modeled by a cognitive map. The cognitive map is a directed causal graphs that can be used to model complex dynamic system. Also shown is the propagation of variance estimates of uncertainty associated with the presence of a fault and with the arcs, representing strength of causality, in the cognitive map. The proposed approach can provide insights into the dynamic character of the system, and help, explain away intermittent fault behavior.

Using Fuzzy Cognitive Maps for Prediction of Knowledge Worker Productivity Based on Real Coded Genetic Algorithm
Improving knowledge worker productivity has been one of the most important tasks of the century. However, we have few measures or management interventions to make such improvement possible, and it is difficult to identify patterns that should be followed by knowledge workers because systems and processes in an organization are often regarded as a death blow to creativity. In this paper, we se...

Usually, in real-world engineering problems, there are different types of uncertainties about the studied variables, which can be due to the specific variables under investigation or interaction between them. Fuzzy cognitive maps, which addresses the cause-effect relation between variables, is one of the most common models for better understanding of the problems, especially when the quantitati...

In this paper, a new control strategy for energy management in Plug-in Hybrid Electric Vehicles (PHEVs) using Fuzzy Cognitive Map (FCM) is presented. In this strategy, FCM is used as a supervisory control such that the State of Charge (SoC) of the battery is kept in the acceptable range and fuel consumption per kilometer is reduced, in addition to providing the request power. Since this method ...
متن کاملDeveloping Initial State Fuzzy Cognitive Maps with Self-Organizing Maps
Using soft computing methods, the authors collect and process relevant user-generated information from the web. Through the use of self-organizing maps, fuzzy cognitive maps are constructed. The fuzzy cognitive map is a generated representation of the emergent web semantics of the dataset. In the next step, the fuzzy cognitive maps are enriched with related lexical content and stored in a graph...
