Energy efficiency combination evaluation method of machine tool product manufacture system

Abstract

The invention discloses an energy efficiency combination evaluation method of a machine tool product manufacture system. The method comprises the following steps: firstly, establishing a three-layer energy efficiency management evaluation index system of the comprehensive evaluation of machine tool product manufacture from an energy resource angle; then, establishing a mathematical model of the dynamic evaluation of the energy efficiency of the machine tool product manufacture; and finally, combining an analytic hierarchy process, a grey correlation method and a fuzzy comprehensive evaluation method to evaluate the manufacture energy efficiency by aiming at the mathematical model. On the basis of the statistical data of energy utilization and historical and current production data, the energy consumption of each hierarchy of the manufacture system is comprehensively considered mainly by aiming at the collection of a wireless sensor technology, a network technology and the like, qualitative analysis and quantitative analysis are effectively combined, subjectivity and uncertainty in an enterprise energy efficiency evaluation process are favorably avoided, and the systematicness and the reasonability of an evaluation result are effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of energy efficiency optimization control of manufacturing systems in the machine tool product manufacturing industry, in particular to an energy efficiency combination evaluation method for machine tool product manufacturing systems. Background technique [0002] As a pillar industry of the national economy, the manufacturing industry not only creates huge economic wealth, but also consumes a lot of manufacturing resources, especially energy, and has a serious impact on the environment. Especially in developing countries like China, the energy consumption of the manufacturing industry is huge, and the energy utilization rate is lower. For example, as the main component of the discrete processing and manufacturing system, the number of machine tools in my country ranks first in the world, and the total rated power of machine tool equipment is equivalent to about three times the total installed capacity of th...
