Diagnostics methodology of faults in television receivers on the base of hyerid expert systems

Abstract

The diagnostics of faults in television receivers of the fourth generation is investigated in the paper aiming at the diagnostics methodology development of faults in television receivers and the creation of the hybrid expert system on its base. As a result the methodology of the fault diagnostics has been suggested and developed. The quasirelation model of the knowledge storage has been suggested and realized. The modified mathematical model of the knowledge base has been suggested. The model of the fault search process has been constructed. Methodological recommendations for the practical use of the suggested approach to the diagnostics have been developed, the software of the diagnostics procedures has been created. The diagnostic expert system developed has been introduced into operation on two enterprises. The application of the diagnostic expert system makes it possible to reduce essentially the time of the service technical specialist trainingAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
