研究由TPL、生鲜电商、生鲜产品供应商组成的三级供应链系统,其中生鲜农产品的市场需求受网上零售价格、安全追溯系统可用性、新鲜度的影响。在TPL主导下,运用Stackelberg博弈模型,分析生鲜电商、生鲜产品供应商不同领导权下的最优决策和最大利润,得出以下结论:生鲜产品供应商作为第二领导下的TPL利润、安全追溯系统可用性、保鲜水平、市场需求均大于其作为第三领导时的情形;不同领导权对供应链企业的利润也会产生影响,利润偏向于领导权大的一方。然而不管哪种决策模型,其供应链利润均小于集中决策下的情形。 相似文献

在我国当前生鲜农产品易受自然风险影响以及成员合作关系不稳定的现实下,本文通过构建自然风险和农业保险两种模式下的供应链利润模型,首先研究了两部收费制对供应链系统的协调作用及对成员合作关系的影响;然后探讨了农业保险的设定和理赔机制,对比分析了农业保险对供应链利润及成员合作关系稳定性的影响,最后通过算例验证模型的结果,并给出决策意见。研究表明:自然风险下两部收费制能协调生鲜农产品供应链,但供应链合作关系不稳定;引入农业保险不仅可以有效管理自然风险,还能增加供应链整体及各级成员的收益;随着自然灾害系数的上升,农业保险下生鲜农产品供应链合作关系稳定性也会下降,但相比较于自然风险下的供应链系统,其稳定性更好。 相似文献

针对由生鲜产品供应商和“前置仓模式”下的生鲜电商组成的二级供应链保鲜努力水平和“最后一公里服务”努力水平偏低的问题,从公平关切视角探究其原因。运用博弈论方法,通过建立Nash讨价还价模型,分析与比较不同公平关切情形下供应链主体的最优决策以及与之对应的收益和效用。结果表明,供应商的公平关切会降低生鲜电商保鲜努力水平和“最后一公里服务”努力水平,而且供应链成员的公平关切总是伴随着各自渠道收益比的提升和供应链总效用的损失。最后,通过设计“收益共享+成本分担”混合契约,提高电商保鲜努力水平和“最后一公里服务”努力水平,使供应链总效用达到最优。数值分析验证了相关结论。 相似文献

为提高生鲜农产品流通效率,增加农户收入,对“互联网+”背景下生鲜农产品供应链的全渠道零售模式进行系统分析。以合作社和超市组成的“农超对接”式供应链为研究对象,基于消费者效用理论获得渠道需求,探讨由超市自营电商平台和超市提供平台服务并与合作社分成两种渠道运营模式下各决策变量,以及合作社、超市和系统总体收益的变化,借助数值分析进行研究。结果表明,合作社通过超市实体和超市的电商平台销售生鲜农产品,超市分享一定比例的合作社在平台获得的收益。这种渠道模式对合作社、超市和供应链系统而言都是较优的选择。 相似文献

针对如何有机结合评论激励和质量激励以实现更优的供应链协调效果,以电商平台、商家和消费者组成的三级网购供应链为研究对象,运用博弈论方法构建考虑消费者评论影响的网购供应链协调模型。通过对模型最优决策的求解分析和数值模拟,讨论单独实施评论激励或质量激励和同时实施两种激励,以及不同质量影响系数、不同消费者评论影响系数、不同消费者评论成本下的协调情况。结果显示,电商平台通过采用适当的评论激励和质量激励,能够在提升商品质量和消费者评论意愿的同时实现网购供应链的协调。为此,电商平台应对不同价值商品设置不同程度的激励水平,且两种激励的实施要相互配合以达到最优的协调效果。 相似文献

为研究不同主导权下农产品电商供应链收益分配问题,构建Stackberg博弈模型,对农产品生产商、第三方物流企业、电商企业构成的三级农产品供应链的集中决策模式和3种分散决策模式下成员最优决策行为进行分析,研究主导权对供应链最优决策的影响。结果表明,主导权对供应链成员的最优决策有显著影响,供应链成员拥有主导权时比其处于跟随地位时收益要高;在同一主导权下,拥有主导权的成员的收益要高于其他跟随地位的成员,但第三方企业除外;3种不同主导权分散决策模式下的供应链的总体利润均小于集中决策下的总利润。 相似文献

Complex Advanced Driving Assistance Systems (ADAS) and Autonomous Vehicle (AV) technology are increasing the number of vehicle recalls. At the same time, financial risks resulting from extensive product recall events can severely affect vehicle manufacturers and their suppliers, exposing the automotive supply chain to business continuity, legal and reputational risk. However, these risk implications are under-appreciated by large segments of the supply chain. This study shows that product recall events are increasing in general but recall events associated with ADAS/AV technology form an increasingly large percentage of these recall events. Based on this analysis, we describe ADAS/AV-specific aspects of risk mitigation and present a multidimensional approach, combining production-centric risk mitigation avenues in the automotive supply chain with the transfer of residual financial risks via insurance. We find that this comprehensive risk mitigation approach benefits in higher transparency of total production costs and increased resilience of the automotive supply chain. Against the background of an increasing product recall risk resulting from the increasing automation and interconnectedness of modern vehicles, we therefore suggest a closer, more strategic cooperation between insurance companies, car manufacturers and automotive suppliers for the benefit of all parties. 相似文献

The increasing demands for environmental resource protection and sustainable development have been forcing enterprises to put sustainable supply chain management on their agendas in recent years. At the same time, intense global competition requires organisations to adopt practices that enable them to provide high-quality products and services. In this paper, we consider the problem of comprehensively evaluating the production system in closed-loop supply chains. We first propose an evaluation framework that consists of economic evaluation, product quality evaluation and ecological evaluation modules. Based on mathematical probability theory and the dynamic characteristics of reverse supply chain logistics, we then focus on the evolution dynamics in the quality evaluation dimension, where the concept of product quality, which builds on the reliability and the time-utility value of a product, is proposed. The basic production evaluation model is then extended to incorporate different sustainable procurement strategies, which take into consideration the trade-offs among cost, environment and quality. An outline and corresponding flow chart of corporate procurement strategy optimisation are provided which allow the proposed evaluation model to be implemented in computer-aided decision-making, further providing decision support for production system and supply chain management. Simulation and case studies are presented to promote a better understanding of the model approach and its managerial implications. Results also suggest that quality characteristics of components and sustainable procurement strategies are two important factors that determine the final production performance and should be paid special attention in closed-loop supply chain practice. 相似文献

Assembly process is a critical stage in the formation of product quality and reliability, but related consideration of the produced product reliability and accident risk has not attracted deserved attention in the most assembly quality analysis frameworks. To this end, this paper enhances risk analysis in assembly process quality control, which is advocated by ISO 9001:2015, and presents a risk-oriented assembly quality analysis approach considering the effects of assembly variations on the produced product reliability degradation and accident risk. First, a conceptual QRR chain is presented to illustrate the relationship among assembly process quality (Q), product reliability (R), and failure accident risk (R). Second, a risk-oriented and bidirectional framework for the analysis of assembly process quality is established based on the presented QRR chain aiming to quantitatively identify the risk sources in the assembly process and reduce the risk of failure accidents. Third, an assembly process quality risk model with key function reliability as its core is presented to establish the quantitative relationship between assembly variation and product failure accident risk. Finally, the presented approach is verified through a case study of an assembling quality risk analysing for acid-resistant grinder. 相似文献
