Fuzzy mathematics method plays a positive role in building enterprise management system. By evaluating production quota of an enterprise, it can make a scientific comparison in management level between different corporations. The evaluation model, as the result of applying fuzzy mathematics method, can reflect the fuzzy relations between production quotas clearly through relation matrix, making evaluation index analysis more comprehensive. This is the basis of comparing enterprise management systems and the complete reflection of fuzzy mathematics method’s evaluating role in building enterprise management system. The application of fuzzy mathematics method not only provides support in data and theory for enterprise’s sustainable development but reflects the application of mathematics model to enterprise’s sustainable development in production.
