The Application and the Prospect of Remanufacturing Technologies in the Metallurgical Industry

Advanced surface engineering technologies and resistant coatings on the damaged surface can improve surface properties, extend service lives, reduce maintenance costs and improve product quality in the metallurgical industry.

A corrective maintenance scheme for engineering equipment

Corrective maintenance is a maintenance task performed to identify and rectify the cause failures for a failed system. The engineering equipment gets many components and failure modes, and its failure mechanism is very complicated. Failure of system-level might occur due to failure(s) of any subsystem/component. Thus, the symptom failure of equipment may be caused by multilevel causality of latent failures.This paper proposes a complete corrective maintenance scheme for engineering equipment. Firstly, the FMECA is extended to organize the numerous failure modes. Secondly, the failure propagation model (FPM) is presented to depict the cause-effect relationship between failures. Multiple FPMs will make up the failure propagation graph (FPG). For a specific symptom failure, the FPG is built by iteratively searching the cause failures with FPM. Moreover, when some failure in the FPG is newly ascertained to occur (or not), the FPG needs to be adjusted. The FPG updating process is proposed to accomplish the adjustment of FPG under newly ascertained failure. Then, the probability of the cause failures is calculated by the fault diagnosis process. Thirdly, the conventional corrective maintenance recommends that the failure with the largest probability should be ascertained firstly. However, the proposed approach considers not only the probability but also the failure detectability and severity. The term REN is introduced to measure the risk of the failure. Then, a binary decision tree is trained based on REN reduction to determine the failure ascertainment order. Finally, a case is presented to implement the proposed approach on the ram feed subsystem of a boring machine tool. The result proves the validity and practicability of the proposed method for corrective maintenance of engineering equipment.     

新产品质量对闭环供应链再制造模式选择的影响

研究了新产品质量对闭环供应链回收再制造模式选择的影响。借助博弈论,建立了原制造商外包再制造和授权再制造的Stackelberg博弈模型,利用逆向归纳法解得两个模型的均衡解和供应链利润,并对均衡结果进行了比较分析。研究发现：外包再制造模式的供应链利润、消费者剩余、社会福利均优于授权再制造模式。原制造商选择外包再制造模式的利润要高于授权再制造模式,而第三方制造商最优策略受再制品价值折扣与新产品质量的影响。当再制品价值折扣系数与回收规模满足一定条件,而且新产品质量较高时,原制造商采取外包模式对环境更加友好。     

The impact of information transparency on the dynamic behaviour of a hybrid manufacturing/remanufacturing system

A combined manufacturing/remanufacturing system is modelled and its dynamic behaviour is investigated using a control engineering approach. The model is an extension of the automated pipeline, inventory and order based production control system (APIOBPCS), which is well understood from a dynamic perspective. It is assumed that the remanufacturing process is based on a PUSH policy. Utilising different levels of information transparency from the remanufacturing process, three system types are developed and compared. Mathematical and simulation analyses of the system types were undertaken and their robustness to remanufacturing process uncertainties were tested. Our analysis indicates that the greater the degree of information transparency, the greater the robustness of the hybrid system.     

Proactive remanufacturing timing determination method based on residual strength

Nowadays, since the resources of remanufacturing are the ‘cores’, the uncertainty in quantity and quality of the ‘cores’ is an obstacle in remanufacturing engineering. To solve this problem, production management and design for remanufacturing have been discussed in the former studies. However, the current remanufacturing mode, which is carried out in the end of life cycle, is reactive. To delimit the uncertainty of ‘cores’, the concept of proactive remanufacturing is presented in this paper. And one issue is to identify the proactive remanufacturing timing. In the beginning, the reactive remanufacturing timing and proactive remanufacturing timing are introduced. Then, to characterise the remanufacturability of components, the concept of residual strength is proposed. To identify the proactive remanufacturing timing, the mathematical model is established based on the residual strength, remanufacturing value and technical feasibility. Based on this model, the timing determination method in proactive remanufacturing is presented and expanded. Finally, to validate this method, the proactive remanufacturing timing of engines is determined by analysing the crankshaft. As a consequence, in the proactive remanufacturing mode, the remanufacturing rate of product might be increased. Thus, the proactive remanufacturing could provide a new perspective in future remanufacturing engineering.     

Joint hybrid repair and remanufacturing systems and supply control

The control of a stochastic manufacturing system that executes capital asset repairs and remanufacturing in an integrated system is examined. The remanufacturing resources respond to planned returns of worn-out equipment at the end of their expected life and unplanned returns triggered by major equipment failures. Remanufacturing operations for planned demand can be executed at different rates and costs corresponding to different replacement and repair modes. The replacement components inventory is provided by an upstream supply with random lead times. The objective is to determine a control policy for both the supply and remanufacturing activities that minimises the average repair/replacement, acquisition and inventory/shortage total cost over an infinite horizon. We propose a suboptimal joint remanufacturing and supply control policy, composed of a multi-hedging point policy (MHPP) for the remanufacturing stage and an (s, Q) policy for the replacement parts supply. The MHPP is based on two inventory thresholds that trigger the use of predefined remanufacturing modes. Control policy parameters are obtained combining analytical modelling, simulation experiments and response surface methodology. The effects of the distribution, mean and variability of the lead time are tested and a sensitivity analysis of cost parameters is conducted to validate the proposed control policy. We also show that our policy leads to a significant cost reduction as compared to a combination of a hedging point policy (HPP) and an (s, Q) policy.     

Implications of product upgrading confronting supplier remanufacturing

It is generally believed that new products upgrading is an effective strategy to deal with the cannibalisation problem from remanufacturing, however, it is not clear how the new product upgrading strategy affect the decision-making of the downstream manufacturer and the upstream supplier. By examining the relationship between supplier remanufacturing profits and product cannibalisation, we develop two models to investigate the implications of the manufacturer's product upgrading confronting supplier remanufacturing. The results show that an product upgrading strategy can effectively enhance the manufacturer's profits if the investment cost is relatively low. Although the product upgrading strategy may hinder the remanufacturing operations, it will always be beneficial for the wholesaling of the supplier's new products. Therefore, the upgrading strategy can mitigate cannibalisation problems and create an optimal pareto improvement for both parties. Finally, we conduct a data analysis to provide additional managerial insights regarding the supply chain.
