Problems solved by technology
[0006] The present invention is in order to make up for the following three deficiencies in the production optimization method of green air-conditioning products in the prior art: 1. The prior art mainly uses exact values or trapezoidal fuzzy sets to describe the evaluation information of the production mode of green air-conditioning products, and the subordinate of trapezoidal fuzzy sets The degree is an accurate value, which cannot fully describe the high uncertainty of the evaluation information of green air conditioners, and cannot guarantee the accuracy and reliability of the information representation results; 2. The existing technology mainly uses the evaluation matrix of the production mode of green air conditioners to determine the optimal production 3. The existing technology mainly uses the ideal point method or case analysis method to determine the optimal production plan of green air-conditioning products, and only considers the two options of acceptance and rejection , used to deal with the two-way decision-making problem, which cannot meet the requirements of complex air-conditioning production decision-making situation and uncertainty information processing

specific Embodiment
[0060] figure 1 It is a specific embodiment of the present invention, and this embodiment is an air-conditioning production optimization method based on an interval-type fuzzy decision-making rough set model. In order to determine the optimal production mode of green air-conditioning products, first define an interval-type fuzzy information system. Interval type two fuzzy information system is a quaternion IS=(U, AT, V, f), wherein, U is a non-empty finite set of objects, which is called domain; AT is a non-empty finite set of attributes; V=∪ c∈AT V c and V c is the value range of attribute c; f:U×AT→V is a function, for any c∈AT, z∈U has f(z,c)∈V c , where f(z,c) is an interval type II fuzzy number. Suppose U={z 1 ,z 2 ,…,z m} is a discrete set with m feasible production methods of green air-conditioning products, AT={c 1 ,c 2 ,...,c n} is the index set of interval type II fuzzy information system, mainly including control system, cooling power, heating power, mater...

Description
technical field [0001] The invention relates to the technical field of production optimization of air-conditioning products, in particular to an optimization method for production of air-conditioning based on an interval type-two fuzzy decision-making rough set model. Background technique [0002] my country is the world's largest air-conditioner manufacturing base, with output accounting for more than 70% of the world's total. In the traditional production process of air-conditioners, various environmental wastes such as noise, waste gas, waste water, waste oil, and waste residues will be generated, which will affect the ecological environment and human beings. Threats to survival and development. In recent years, the government has increasingly emphasized that air-conditioning products should meet the indicators of "green, environmental protection, and health", and consumers have also paid more and more attention to the green characteristics of air-conditioning products. T...
