Fuzzy logic expert system : a new approach to diagnosis in telecommunication

This thesis presents a new approach to fault diagnosis in telecommunications. The principles of fuzzy theory and fuzzy expert systems will develop a framework for the diagnosis and analysis of results produced by the circuit measurement instruments of the telephone lines. The thesis is a case study in which a fault is isolated and then, membership functions are empirically produced to represent fault parameter behavior. Fuzzy system rules are then constructed and the whole module system is tuned and put to testing. The results of the tests are thoroughly discussed, concluding with recommendations for extending the case module study in for the purpose of constructing a complete fuzzy diagnostic system
