Abstract

The invention discloses an equipment design / maintenance scheme intelligent decision-making method based on digital twinning, and belongs to the technical field of advanced manufacturing and automation. The method comprises the following steps: 1, carrying out structure analysis and function analysis on key equipment, and carrying out mechanism model construction and data model construction to obtain a digital twin modeling module of the key equipment; 2, carding data and information required by design / maintenance service according to the digital twin modeling module of the key equipment obtained in the step 1, formulating an evaluation criterion of a design / maintenance optimal scheme, and obtaining a decision scheme alternative set; 3, according to the decision scheme alternative set obtained in the step 2, performing multi-attribute multi-scheme decision of a complex group to obtain an alternative scheme sequence under a design / maintenance service task; and 4, when the alternative schemes are reasonably ranked, outputting the alternative schemes as optimal schemes. According to the method, the problem that the intelligent level of industry design, production, management and service is still low at present is solved.

Description

technical field [0001] The invention belongs to the technical field of advanced manufacturing and automation, and relates to an intelligent decision-making method for equipment design / maintenance schemes based on digital twins. Background technique [0002] The key equipment in the nuclear power industry, such as nuclear power units, is a typical high-end equipment, which has the characteristics of complex system composition, customized design, high equipment value and long construction process. Its full life cycle management covers R&D, design, procurement, construction, Installation, commissioning, operation, maintenance and other links. Usually the on-site commissioning and operation and maintenance departments need to feed back the relevant fault information to the design department and equipment manufacturer in the form of TCR sheets or letters, asking them to assist in providing solutions, and the design department will provide services according to the equipment condi...
