【摘要】：当今,供应链的完善在市场竞争中起着越来越突出的作用。因此,供应链网络结构的优化是价值创造的重点。供应链的在优化过程中,网络结构的构建战略起着至关重要的作用。通过查阅文献发现,传统的供应链设计方法是使用离散时间点严格地预定义供应链的网络超级结构,其优化过程只是决定供应链网络中每个层次成员的数目及其连通性,该方法可能会限制商业增值的可能性。另一方面,在供应链的设计领域,更激烈的挑战在于市场不断地和不可预测性的变化(Brownand Eisenhardt,1998)。为了在市场竞争中获得成功,供应链的各个成员需要清楚的明白市场需求及市场约束,制定合理的生产策略,提高满足不同客户的特定需求的能力,即构建灵活供应链。所谓灵活是指具有较强的鲁棒性和响应能力。然而,对于已经存在的供应链网络,在运行过程中,一旦发生网络故障(如设备故障、需求大幅增加,运输延迟等),即使是灵活供应链,也很难快速响应变化,造成供应链网络效率的迅速下降,甚至是网络瘫痪。为了解决上述困难,首先,本文在第二章中利用数学规划原理,建立了供应链网络的灵活设计-计划模型,该模型不需要预定义供应链的网络超级结构,所有网络节点均在优化过程中由模型决定,该方法可以深入挖掘网络的灵活性,得出具有很强鲁棒性和响应能力的供应链网络结构。然后,本文在第三章中通过对供应链网络的灵活设计-计划模型进行修改和完善,得到重构模型。该模型能在供应链网络发生故障时,根据市场容忍时间,快速进行供应链网络的重构,在指定时间内响应变化,提高供应链网络的效率。同时,本文在第二章和第三章中,分别通过算例分析与对比,对供应链的灵活设计-计划模型和重构模型进行了验证。
[Abstract]:Nowadays, the perfection of supply chain plays a more and more important role in market competition. Therefore, the optimization of supply chain network structure is the focus of value creation. The strategy of constructing network structure plays an important role. Through literature review, it is found that the traditional supply chain design method is to predefine the network superstructure of supply chain strictly using discrete time points. The optimization process only determines the number of members and their connectivity at each level in the supply chain network. This method may limit the possibility of commercial value-added. On the other hand, in the area of supply chain design, the more intense challenge is the constant and unpredictable changes in the market, Brown and Eisenhardt. In order to succeed in market competition, each member of the supply chain needs to understand clearly the market demand and market constraints and formulate a reasonable production strategy. To improve the ability to meet the specific needs of different customers is to build a flexible supply chain, which refers to having strong robustness and responsiveness. However, for the existing supply chain network, once the network failure (such as equipment failure, demand increase, transportation delay, etc., even flexible supply chain, etc.) occurs during the operation process. It is also very difficult to respond quickly to changes, resulting in a rapid decline in supply chain network efficiency, or even network paralysis. In order to solve the above problems, in the second chapter, the flexible design-plan model of supply chain network is established by using the principle of mathematical programming. The model does not need to predefine the network super structure of supply chain. All the network nodes are determined by the model in the process of optimization. This method can excavate the flexibility of the network and obtain the supply chain network structure with strong robustness and response ability. Then, in the third chapter, by modifying and perfecting the flexible design-plan model of supply chain network, we get the reconfiguration model, which can tolerate the time according to the market when the supply chain network fails. In order to improve the efficiency of the supply chain network, the supply chain network can be reconfigured quickly to respond to the change within a specified time. At the same time, in the second and third chapters, the flexible design-plan model and the reconfiguration model of the supply chain are verified by the example analysis and comparison, respectively.
