Problems solved by technology

However, the papers on the evaluation system of digital twin workshops are extremely scarce, and the evaluation methods and evaluation index construction need to be further improved.
In the evaluation process of the digital twin workshop, there are many evaluation indicators involved, and the evaluation indicators cannot be absolutely quantified, and the evaluation habits of the evaluation subjects are also different, resulting in strong ambiguity in the evaluation

Abstract

The invention relates to a hesitant fuzzy language-based digital twinning workshop quality evaluation method, which effectively avoids the loss of evaluation information, enables the evaluation to better conform to the intention of a decision maker, and improves the precision of an evaluation result. According to the technical scheme, the method comprises the following steps: constructing an evaluation index system; determining the weight of the evaluation index by using an OWA operator weighting method; adopting an OWA operator based on an arithmetic progression to carry out weight calculation on the evaluation index of the digital twin plant, and obtaining a weight vector of each index layer in a digital twin plant quality evaluation system through collection of decision data, determination of a position weight vector, calculation of an absolute weight and normalization processing of the absolute weight; determining an operation rule of the hesitant fuzzy language; collecting a decision comment set of the index layer; determining an evaluation result of the first-level index layer; gathering the evaluation results of the first-level index layer, and gathering the evaluation results in stages. The accuracy of the evaluation result is improved.

Description

technical field [0001] The invention relates to the technical field of workshop quality evaluation methods, in particular to a digital twin workshop quality evaluation method based on hesitant fuzzy language. Background technique [0002] The manufacturing industry is the main body of the national economy, and the new round of industrial revolution and the development of information technology have made intelligent manufacturing a key field for the development of countries all over the world. As a key enabling technology for the development of intelligent manufacturing, digital twinning originated in the military field, but it has quickly won the favor of industrial enterprises and has become a research hotspot in the field of manufacturing. The world-renowned consulting firm Gartner has listed digital twins as one of the top ten strategic technology trends for two consecutive years (2017 and 2018). [0003] At present, most of the research on digital twin technology focuse...
