A Methodology for the Valuation of Quality Management System in a Fuzzy Environment

The needs and demands of the present markets have favoured the development of Quality Management. Among the different strategies related to quality management that an organisation can develop, the establishment of quality systems in accordance with the requirements established in ISO 9000 standards has acquired a special importance. The worldwide implementation and certification of ISO 9001 quality management systems have increased significantly during the lasts years. However, the contribution of ISO 9000 certification is a controversial issue. While firms continue to seek certification and some researchers support its value, other studies suggest that it has little value to companies. This work provides a tool that facilitates the valuation of the ISO 9001 quality system in large and small companies. To make it, given the uncertainty this process involves, the use of fuzzy math is very useful.
