So as to form a three-dimensional cross the circulation of the economic construction model. Construct the index system of coal enterprise circular economy. Using analytic hierarchy process to an index system weight assignment. Application multilevel fuzzy synthesis evaluation of the circular economy development level of the measure, is able to overcome the fuzziness of attribute index, identify the coal enterprise circular economy development present situation and limiting factors, and get more objective of comprehensive evaluation results.
