Abstract
China's recycling roadmap and technology scheme for used automotive electronic control components are investigated. The mathematical analysis model of the remanufacturing process is established on the basis of stochastic network technology, as well as on the graphical evaluation and review technique (GERT). In addition, the calculation method used for estimating single-product remanufacturing time is examined. The objective of this study is to determine the probability of success for the remanufacturing of used automotive electronic control components and remanufacturing time. On the basis of experimental parameters, we simulate the remanufacturing process using the Monte Carlo simulation in Crystal Ball. Compared with the result of the GERT model (8.5114 h), the simulation error rate is 0.225%. This consistency in results indicates that both the stochastic network model and Crystal Ball can accurately simulate the remanufacturing process of used automotive electronic control components, making these techniques feasible approaches for such processes. Aside from numerical experiments on and sensitivity analyses of key processes, the relationship between total remanufacturing time and five influencing factors is identified. Total remanufacturing time can be significantly reduced by optimizing the key processes. The optimization methods are also investigated.
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
