Abstract:

Remanufacturing is an effective way to develop the circular economy, which is also an important tool to deal with the resource shortage and environmental pollution. There are a lot of waste coal machines in China. It is very important to do the related research of remanufacture these machines both in theory and practice. This paper is an attempt to identify the evaluation criteria of remanufacturability for coal machinery and establish the assessment model of remanufacturability for coal machine based on the expert scoring method and analytic hierarchy process. The empirical study is then carried out based on the data collected from the enterprises. The results of the empirical analysis are highly agreed with the situations of the enterprise, implying that the assessment system and model of remanufacturability for coal machinery established in this paper could be applied to the coal industry.

Key words: Coal machine, Assessment of remanufacturability, Analytic hierarchy process
