Fuzzy Relational Degree Evaluation Model of Recycling Economy for Coal Enterprises

On base of analyzing the situation of recycling economy of coal enterprises and establishing the principle of indication system, an evaluation-index system was established, which included four levels structure (economy development, resource utilization, social development and recycling system) and twenty-two indications. According to comparing all kinds of methods of recycling economy, and considering the advantage of methods and character of coal enterprises, a evaluation model of recycling economy in coal enterprises is build based on fuzzy relational degree analysis.
