【摘要】：在竞争日益激烈的商品市场中,供应链作为一个情况复杂的动态系统,既有上游的供应商、制造商等,还有下游的销售商、零售商等。而供应链成员大多都只追求各自利益的最优,进而使供应链容易出现“双边际化效应”,即供应链各成员单方面收益最优,而系统整体可能没有达到最优的现象。所以正确的战略决策来优化供应链,使应链上各成员利益双赢显得尤为重要。因此,研究供应链协调问题已经变得尤为重要。首先,文章在绪论部分主要描述了供应链协调问题以及闭环供应链的研究背景和意义,指出了供应链协调中存在的诸多问题和相应地协调方式方法。在实际生活中,消费者对商品的需求受到许多因素的影响,例如广告宣传、质量监控、售后服务等,文中考虑需求受到销售努力和质保服务等因素对供应链的影响。其次,文中以单一制造商和单一零售商组成的两级供应链为对象,考虑了随机需求下商品需求同时受到销售努力和质保期长度影响,研究了由零售商提高销售努力因素及制造商提供质保服务情形下的供应链模型,并提出了共同分摊销售努力和质保成本及收益共享契约下的供应链协调策略。通过数据模拟得到一些相关的灵敏度分析和管理启示。最后,文章以随机产出为研究背景,针对销售努力影响需求的闭环供应链模型,考虑了集中决策和分散决策下闭环供应链系统的期望利润,并给出了在两种决策下生产商的最优生产,零售商最优销售努力和销售初期最优的订购量。此外,通过证明得出了分散决策下闭环供应链期望利润低于集中决策下闭环供应链的期望利润,并利用改进的合作利润分配机制使得闭环供应链系统达到协调。
[Abstract]:In the increasingly competitive commodity market, supply chain is a complex dynamic system, including upstream suppliers, manufacturers, and downstream retailers, retailers, etc. Most of the members of supply chain only pursue their best interests, which makes the supply chain prone to "bilateral effect", that is, the single income of the members of the supply chain is optimal, and the whole system may not achieve the optimal phenomenon. So the correct strategic decision to optimize the supply chain, so that the interests of each member on the chain is particularly important. Therefore, the study of supply chain coordination has become particularly important. First, the article describes the supply chain coordination and the research background and significance of closed loop supply chain in the introduction part, and points out the problems and corresponding ways of coordination in supply chain coordination. In real life, consumers' demand for commodities is influenced by many factors, such as advertising, quality control, after-sales service, etc., considering the demand, the impact of sales effort and quality assurance services on the supply chain. Secondly, the two level supply chain with a single manufacturer and a single retailer as the object, considering the demand for goods under stochastic demand is also affected by the length of the sales effort and the warranty period, the supply chain model and manufacturers to increase sales efforts factors by retailers to provide warranty service conditions, and put forward to share sales efforts and the warranty cost and revenue sharing contract of supply chain coordination strategy. Through the data simulation, some related sensitivity analysis and management inspiration are obtained. Finally, based on the stochastic output as the research background, according to the sales efforts of the closed-loop supply chain model of demand, considering the centralized and decentralized decision-making of closed-loop supply chain system expected profit, and gives the optimal production of producers in the two decision of the retailer's optimal sales effort and the initial optimal order quantity. In addition, we prove that the expected profit of closed loop supply chain under decentralized decision is lower than that of centralized supply chain under the decentralized decision making, and we can use the improved cooperative profit allocation mechanism to make the closed-loop supply chain system achieve coordination.
