Abstract
Remanufacturing has emerged as a competitive strategy for manufacturers to tackle environmental and economic challenges. In this paper, an integrated fuzzy approach is developed for the evaluation of remanufacturing alternatives. Then, importance weights of main remanufacturing processes and evaluation criteria are obtained through fuzzy extent analysis. Fuzzy hierarchical TOPSIS is then applied to evaluate the alternatives. A case study is presented to demonstrate the applicability of the proposed approach. The analysis results show that it is a viable approach and can be used as an effective tool for design evaluation from the remanufacturing point of view. Finally, conclusions are discussed and future research directions are suggested.
Highlights
Automotive remanufacturing companies are nowadays facing a wide range of challenges
The main fields of challenges analysed in this paper are: the vagueness in respect of fiscal value, environmental regulations and taxation of core parts, the important need for a continuing qualification of staff and engineers, an efficient core management, the adaption of pricing models and the competence to handle the growing variety and complexity
Automotive remanufacturing is of growing importance within the automobile industry
Summary
Automotive remanufacturing is of growing importance within the automobile industry. Nowadays every OEM has programs with remanufactured parts and their market volume is growing [12]. Targeting for an earlier end of production (EOP) of new spare parts, OEMs establish more and more remanufacturing systems. Reasons for this are rising production costs per produced part as an effect of decreasing production output. In many cases production lines and the resources (e.g. staff, machines) are needed for newer production lines [9]. Like all other branches the remanufacturing companies have to address challenges to stay competitive. In this paper today’s most important challenges are highlighted. The aim of this paper is to put important remanufacturing-specific challenges together and create awareness of all responsible
