为研究政府分别实施再制造补贴和回收补贴下不同回收渠道对再制造闭环供应链的决策影响,建立以制造商为领导者,零售商和回收商为跟随者的闭环供应链的Stackelberg主从博弈模型,对比分析两种补贴方式下不同回收渠道的最优定价和回收策略。结果表明,补贴金额的多少会降低产品价格和批发价,刺激消费,提高回收率,增加闭环供应链上所有参与方的利润,而与补贴类别无关;当存在双回收渠道时,回收商与零售商之间回收的竞争强度影响产品售价、回收率和制造商的利润,而回收转移价格仅与补贴类型有关。最后,通过实例分析探讨不同补贴与不同回收渠道对闭环供应链的影响。 相似文献

It is widely agreed that the entry of third-party remanufacturers (TPRs) hurts original equipment manufacturers (OEMs) because remanufacturing cannibalises the new product sales. In this paper, motivated by the practice of mobile phone remanufacturing, we develop a game theoretical model to revisit the impact of third-party remanufacturing on a forward supply chain in which one OEM purchases critical components from one dominant supplier. The OEM may operate the remanufacturing business as cost-efficient as the TPR. Our analytical results show that regardless of the OEM’s remanufacturing capability, third-party remanufacturing could be beneficial to the OEM in that the supplier would lower the wholesale price as a response to the entry of the TPR; in addition, compared with the case without remanufacturing, third-party remanufacturing is always detrimental to the supplier, but the supplier should not always attempt to deter the entry of the TPR because third-party remanufacturing could be less detrimental than the OEM’s in-house remanufacturing. Under certain conditions, the two players in the forward supply chain both prefer third-party remanufacturing over in-house remanufacturing. The key intuition driving this finding is that third-party remanufacturing makes the OEM and the supplier allied; while in-house remanufacturing makes them against each other. 相似文献

This paper investigates a reward-driven policy, employed in a closed-loop supply chain (CLSC), for acquiring used products earmarked for remanufacture. Under the examined model, a single manufacturer sells products through a retailer as well as directly to end users in a forward supply chain. In the reverse supply chain, three different modes of collection are employed to capture used products for remanufacture: they are through a third party, directly by the manufacturer and from the retailer. Mathematical models for both non-cooperative and centralised scenarios are developed to characterise the pricing decisions and remanufacturing strategies that indicate individual and overall supply chain performance. Optimality of all the proposed models is examined with theory. To coordinate and achieve a win–win outcome for channel members, we proposed a three-way discount mechanism for the manufacturer. Extended numerical investigation provides insights on ways to manage an efficient reward-driven CLSC in a dual-channel environment. 相似文献

研究品牌优势对回收商生产模式选择的影响机制,并基于三方博弈模型,运用KKT条件等方法分析不同品牌优势下,回收商选择再制造或翻新的决策条件和利益分配结果。结果表明,在品牌优势较低的情况下,回收商的生产模式选择会依赖回收成本。当回收成本较低时,全部翻新是回收商最优策略,但这会损害品牌制造商和品牌零售商的利益;当回收成本适中时,回收商倾向于部分翻新,此时品牌零售商可以从中获益,但品牌制造商会受到冲击;当回收成本较高时,回收商翻新威胁小,品牌制造商和品牌零售商都会默认接受这一结果。在品牌优势较高的情况下,回收商和品牌制造商有动机达成再制造协议,实现双方的共赢,但品牌零售商会极力反对这一协议。此外,合作再制造模式并不一定能带来更高的消费者剩余,在一定条件下,翻新竞争模式下消费者剩余可能会超过合作再制造模式下的水平。

In this paper, we investigate how buyers’ and suppliers’ distinct perceptions of technology uncertainty affect the relationship between communication frequency and supplier performance. Information processing theory suggests that a fit is desirable between perceived environmental uncertainty and the communication processes between organisations. However, if partners in a buyer-supplier relationship do not concur on the high level of technology uncertainty, it is highly questionable whether increased communication will be effective in increasing supplier performance. Using dyadic data from 86 buyer-supplier relationships, involving 388 respondents, we found that communication frequency was positively related to supplier performance only when both suppliers and buyers perceived high levels of technology uncertainty. When buyers perceived greater technology uncertainty than their suppliers, communication frequency was negatively related to supplier performance. The findings in this study show that it is important to take the distinct perceptions of buyers and suppliers of technology uncertainty into account when assessing the effects of communication frequency. It appears that increased communication is only effective when both parties acknowledge the need to communicate, and can be unfavourable when only one party sees the benefits of it. 相似文献

We address a problem that arises for an original equipment manufacturer (OEM) who produces a product both in new and remanufactured forms. A remanufactured product is produced using the parts harvested from recovered products (cores) upon their disassembly, and it may contain some new parts while the excess good parts from cores are salvaged for profit. Other options are available to the OEM for handling cores that do not require disassembly. It follows that the per-unit remanufacturing cost is not constant and it may change depending on the number of recovered cores, good-part reclamation yields, and sales of remanufactured products. We present analytical results for determining an optimal solution with regard to: (i) quantity of cores to collect, (ii) end-of-life (EOL) options for the cores and (iii) product pricing of new and remanufactured products. Our analysis reveals existence of a ‘limiting part’ that dictates the number of cores to collect and a ‘key part’ that determines the number of remanufactured products to make as well as the fact that the availability of cores does not impact the EOL policy type for a product. Our analysis also enables mapping of product characteristics onto corresponding EOL policy types. 相似文献

Most shops currently maintain a single process plan for each part type manufactured by the shop even when multiple process plans are feasible to produce the part. The use of a static process plan for a part regardless of the product mix and volume robs the shop of production flexibility and efficiency. In this paper, given that multiple process plans for a part exist, a method to determine the best process plan to implement for a part type in a given production scenario defined by a known product mix and volume is addressed. The method selects a set of process plans to implement based on minimizing total material handling and machining time for the part mix and volume. The problem is modelled mathematically and solved using a heuristic algorithm. Experimental results to describe the performance of the algorithm are presented for different production scenarios, problem sizes, and solution strategies. 相似文献

将供应链成员双重行为偏好特征考虑到政府奖惩干预下的闭环供应链决策模型中,采用均值-标准差风险度量准则探讨了决策者行为偏好对闭环供应链最优决策和协调性的影响。结论表明：公平关切行为只是闭环供应链系统内部利润分配的一种手段,零售商和回收商公平关切行为会促使制造商出让部分利润,从而有利于自身利润的提高;回收商风险偏好行为影响回收转移价和回收价,当供应链成员以效用最大化为决策目标时,回收商越喜好风险,对制造商越不利,越厌恶风险,对零售商越不利;有效协调区域受到双重行为偏好特征的影响,供应链成员过度公平关切以及过度喜好风险或过度规避风险都将使收益共享-费用分担契约难以实现供应链协调,当供应链成员的行为偏好在各成员可接受的合理范围内,收益共享-费用分担契约能够实现闭环供应链Pareto改善。 相似文献

Rapid growth in end-of-use and end-of-life products and their current unsustainable disposal methods are the cause of worries among the researchers and academicians across the globe. For that, remanufacturing is emerging as a viable option for sustainable production. Moreover, acceptance of remanufactured products by the consumers is highly essential for the success of the circular economy. Therefore, a study of the purchase intention of the consumers towards remanufactured products becomes inevitable. Here, our research uses meta-analysis to statistically synthesise and analyze the factors relevant to the purchase intention of the remanufactured products. Based on the published literature a total of ten studies are found suitable for the meta-analysis. The result shows that purchase intention of consumers is positively and strongly influenced by attitude and subjective norm, whereas it is moderately influenced by perceived green benefits and perceived behaviour control. In addition, meta-analysis supports the negative relationship between perceived risk and purchase intention. The findings also suggest that consumers who purchase remanufactured electrical and electronics products are less environmentally conscious than consumers who purchase remanufactured automotive products. Further, authors have discussed the managerial implications of the factors which influence the purchase intention of the consumers towards remanufactured products. 相似文献

We conduct an analytical study on remanufacturing channel design and after-sales service pricing, which jointly affect the sustainability and profitability of the supply chain. We model a supply chain with one manufacturer and one independent retailer. The manufacturer, as the Stackelberg game leader, engages in remanufacturing to take advantage of production cost savings. The collection of the used products can be carried out by either the manufacturer or the retailer. After-sales service, for example, extended warranty, is offered with the product and is sold separately. The service provider can be either the manufacturer or the retailer. We use game theoretic models to answer an important research question: How do remanufacturing and after-sales service jointly affect channel selection decisions? We explore the benefits of joint decision making in terms of remanufacturing efficiency and after-sales service performance. We find that it is most efficient for the retailer to collect the used product for remanufacturing and to offer after-sales service, because the retailer simultaneously makes decisions regarding remanufacturing and after-sales service and thus reduces double marginalisation in the supply chain. We also demonstrate numerically how the costs of collecting used products and providing after-sales service impact channel selection decisions. 相似文献

This research studies the configuration problem of a remanufacturing production network together with the decision for return quality thresholds, in which, the manufacturer has multiple remanufacturing facilities to satisfy different market demands. Quality of returns is stochastic, while demand for remanufactured products is either stochastic or deterministic. The problem we considered is to determine facilities to operate, minimum quality to accept into each operating facility, return quantity and demand allocation simultaneously so that the system’s profit is maximised. The problem is formulated as a mixed integer non-linear programming model. Through the use of a numerical example, the impact of quantity of returns, total spending, quality uncertainty, demand uncertainty and transportation cost on the remanufacturing system is analysed. 相似文献
