Waste component remanufacturing process decision-making method based on secondary case-based reasoning

Abstract

The invention belongs to the field of machine tool remanufacturing, and particularly relates to a waste component remanufacturing process decision-making method based on secondary case-based reasoning. The method mainly comprises the steps of (1) analyzing a failure mode of a waste component, and describing the failure mode in an OWL (Web Ontology Language); (2) introducing a Pearson correlation coefficient, and establishing a similarity calculation method for similar remanufacturing process cases; and (3) performing primary remanufacturing process case-based reasoning and secondary remanufacturing process parameter reasoning so as to acquire candidate remanufacturing processes and parameters thereof, and deciding an optimal remanufacturing process. According to the invention, an optimal process scheme meeting remanufacturing requirements can be acquired, scientific decision-making for the remanufacturing process is realized, and effective decision-making support is provided for formulation of a remanufacturing process scheme.

Description

technical field [0001] The invention belongs to the field of machine tool remanufacturing, and in particular relates to a decision-making method for remanufacturing process of waste parts and components based on secondary instance reasoning. [0002] technical background [0003] Europe and the United States, where the remanufacturing industry is relatively developed, have a high degree of remanufacturing process. From the pre-inspection, dismantling, cleaning, etc. of waste machine tools to the final remanufacturing assembly process, there are process specification documents as its support, and its batch remanufacturing process The manufacturing production method also fully guarantees the quality of remanufactured machine tools. However, my country's remanufacturing industry started relatively late, and currently does not have a large-scale production method. Due to the underdeveloped recycling logistics system of waste machine tools in my country, most of the waste machine...

Problems solved by technology

At present, there are the following problems in the decision-making process of the remanufacturing process of waste machine tools: (1) manual decision-making is mainly based on experience, and the efficiency of remanufacturing and repairing is low; (2) the remanufacturing and repairing process is too complicated, and the degree of repair quality fluctuation is too large; (3) Improper choice of remanufacturing repair process, resulting in waste of resources; (4) Lack of testing process, imperfect quality testing of waste parts and remanufactured parts
