An Implementation Tool for the Expertise Model using CommonKADS Methodology

Abstract — Our work is a part of the manufacturing monitoring systems, using the model of knowledge creation for the realization of industrial diagnosis dependability aspects. Knowledge capital has an important role in organizations, particularly in the industrial sector based on knowledge. The aim of this work consists in outsourcing tacit knowledge into explicit knowledge at the thermal power plant of Jijel city in Algeria. For our analysis, we used the methodology ''CommonKADS' ' of knowledge acquisition, which is standard for the development of knowledge-based systems in Europe; but, the weak points are (i) the lack of an implementation tool for this method, (ii) weak modeling language CML (Conceptual Modeling Language), because it is a semi-formal language, and (iii) lack of inference (the role of knowledge-based). Therefore, we proposed the expert system generator G2 as a computerized model of expertise for this methodology; it is a highly efficient development assistant of knowledge-based systems. This comes from the fact that it contains a natural and formal language. It is structured and allows the definition of all the elements of the methodology CommonKADS, it offers possibilities more than an inference engine. The studied thermal power plant is using an online monitoring system; it makes the detection of signs that show abnormalities using alarms. We have proposed a knowledge-based system that follows the detection to diagnose in real-time the process that ensures good continuity of production and availability of inputs, and results in quality of monitoring equipment and rapid diagnosis. Saved expertise should allow a better fit of interventions. Our contribution is in the conduct and support the diagnosis of a production system. The proposal is a tool for implementing CommonKADS, based on improvement of its weaknesses.
