Problems solved by technology

However, the evaluation of sustainable chemical projects obviously increases the complexity of the evaluation compared with the evaluation of traditional chemical projects because of the comprehensive consideration of the three major factors of economy, society and environment
Although literature [1] takes into account the conflict factors of sustainable chemical project evaluation, it ignores its complexity, so there are still some defects in the evaluation of complex sustainable chemical project

Embodiment Construction

[0054] The present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0055] The mixed-conflict sustainable chemical evaluation method of this application specifically includes three steps, which are:

[0056] Step 1) Carry out mathematical modeling, use the bipolar language fuzzy set operator to evaluate the options u for all experts i About Criterion c j The bipolar language fuzzy evaluation values ​​are assembled to obtain the candidate scheme u i About Criterion c j Bipolar language fuzzy comprehensive evaluation value set w represents the weight vector of the expert, which is defined later, The superscript indicates the evaluation value given by the o-th expert.

[0057] Step 2) Update the criterion weights according to the cognitive map of bipolar language fuzzy.

[0058] Step 3) Sort the schemes according to bipolar linguistic fuzzy VIKOR method, and select the most suitable project for...

Abstract

The invention discloses a hybrid conflict type sustainable chemical engineering evaluation method. The hybrid conflict type sustainable chemical engineering evaluation method includes the specific steps of 1, conducting mathematical modeling and aggregating bipolar language fuzziness evaluation values of to-be-selected schemes ui of all experts with respect to criteria cj by bipolar language fuzziness aggregation operators so as to obtain a comprehensive bipolar language fuzziness evaluation value set (shown in the description) of the to-be-selected schemes ui with respect to the criteria cj;2, updating the criterion weight according to bipolar language fuzziness cognitive maps; 3, ordering the schemes according to a bipolar language fuzziness VIKOR method and selecting an optimal investment project. The hybrid conflict type sustainable chemical engineering evaluation method has the advantages that the hybrid conflict type sustainable chemical engineering evaluation method, namely a comprehensive bipolar language fuzziness evaluation method, takes multiple criteria, multiple experts and relevance among the criteria comprehensively and is of great help to chemical engineering enterprises in making decisions suitable for chemical engineering development goals so as to protect the environment and energy resources.

Description

technical field [0001] The invention belongs to the field of comprehensive intelligent decision-making evaluation, and in particular relates to an evaluation method of a mixed conflict type sustainable chemical project. Background technique [0002] Sustainable development provides a new way out for the traditional chemical industry, which emphasizes the comprehensive consideration of the three major factors of economy, society and environment. However, most of the traditional chemical evaluation methods are economically oriented, ignoring environmental and social factors; or even considering environmental and social factors, but not considering the contradictory characteristics between the three. It is noticed that bipolar fuzzy set compares with other fuzzy sets, and it is a good description of this contradiction. Literature [1] (Y.Han, Q.Luo, and S.Chen, Hesitant bipolar fuzzy set and its application in decision making[C]. Frontiers in Artificial Intelligence and Applica...
