Uma contribuição ao desenvolvimento e avaliação da qualidade de sistemas de supervisão industrial à luz das normas ISO/IEC 9126 e 14598

Abstract

The supervisory systems are increasingly present in everyday industry, because the guarantee of having information about production processes in diverse locations simultaneously is essential to good monitoring and control. However, developers these tools do not utilize development models, nor methods for assessing software quality, making projects more expensive, due to rework, and causing client dissatisfaction for not meeting fundamental requirements. Therefore, there is a need to organize the process of development and evaluation for supervision softwares. ISO / IEC 9126 and 14598 are used in methodology, as they provide good support to identify essential characteristics of supervisory software, to create quality standard and to development of evaluation methodology. This research proposes model for development of supervisory software, accompanied by method of quality assessment based on fuzzy logic to analyze subjective opinions of specialists about supervisory requirements. The efficiency to use model was verified in educational field through a project realized by students. The assessment revealed quality of each requirement and showed that the complete software attended 69% of the standard of quality. The attributes that were with or without failures were identified, and the evaluation shows errors that need to be solved for software can be delivered for client.
