Proposal for a prototype of an expert system for the mechanical and electrical diagnosis of automobiles

Abstract

The vehicle is an indispensable resource in today's society to carry out work, social, leisure, emergency activities, etc., where its maintenance is essential for its correct operation. However, in many situations we find unforeseen events with the car that can be avoided if anomalies can be detected in time, or in any case have a preliminary diagnosis of the car problem, before resorting to a specialist and avoiding large repair costs. This article presents the proposal for a prototype of an expert system to diagnose common mechanical or electrical faults in a car. This prototype is intended for users who generally do not know about the operation or maintenance that their car needs. The work was based on a descriptive investigation identifying a problem and proposing a solution to the identified problem. For the construction of the prototype, different tools that fit the problem were evaluated, in that sense the VisiRule tool was selected. VisiRule has advantages over other tools such as its ease of representing the problem and its accelerated strategy for prototyping. In this first stage of the project, a first prototype of the expert system was generated that covers general and common problems about electromechanical failures in a car. In this work, the construction of the prototype, the applied methodology, the results and the conclusions obtained are described in detail.
