【摘要】：随着市场经济的不断发展,如何提高竞争优势已成为各供应链共同努力的方向。根据供应链概念的来源可以知道,价值是供应链竞争能力最根本的表现形式。供应链价值与供应链的长期发展相关,寻求供应链价值的实现实际上是在寻求一种长期效益,能够均衡地实现供应链中各参与企业以及终端消费者的利益,符合可持续发展的理念,能从根本上提升供应链的竞争能力。供应链中任何环节的优化都是为了最终实现供应链价值,而在供应链的所有环节中,运输占据了桥梁的位置,对供应链价值的实现起到了关键性的推动作用。因此本文选取了比较具有代表性的煤炭运输,围绕供应链价值对其进行优化。本文采用了定性与定量相结合、系统分析和系统仿真等方法,首先在理论部分,详细分析了供应链价值的涵义以及运输价值与供应链价值的关系,提出运输优化应该遵循供应链价值的核心理念,以顾客价值的满足和成本优化为双重目标对运输问题的优化提出了建议,其中特别强调了顾客价值的重要性。其次,介绍了为了促进煤炭供应链价值的实现,煤炭联合运输在选择运输方式以及协同运输时需要遵循相应的原则,为后面模型的建立奠定理论基础。文章最后部分构建了以时间价值最大化和成本最小化为目标函数的优化模型来解决实际运输中的路径选择问题。同时对该模型进行了仿真实验,利用优化算法进行编程求解,得到可行的方案,并验证了在供应链价值理念中,时空价值的满足与运输成本最小化并不是完全冲突的关系,借助此方法解决了基于供应链价值的多节点以及多运输方式的运输优化问题。
[Abstract]:With the continuous development of market economy, how to improve the competitive advantage has become the direction of each supply chain to work together, according to the source of supply chain concept can be known. Value is the most fundamental form of expression of supply chain competitiveness. Supply chain value is related to the long-term development of supply chain. In fact, seeking the realization of supply chain value is looking for a long-term benefit. It is in line with the concept of sustainable development that the interests of the participating enterprises and the end-consumers in the supply chain can be realized in a balanced manner. Can fundamentally enhance the competitiveness of the supply chain. The optimization of any link in the supply chain is to achieve the ultimate value of the supply chain, and in all aspects of the supply chain, transport occupies a bridge position. It plays a key role in the realization of supply chain value. Therefore, this paper selects the more representative coal transportation, and optimizes it around the supply chain value. This paper adopts the combination of qualitative and quantitative. System analysis and system simulation methods, first in the theoretical part, detailed analysis of the meaning of supply chain value and the relationship between transport value and supply chain value. It is proposed that transportation optimization should follow the core concept of supply chain value, and the optimization of transportation problems should be based on the dual objectives of customer value satisfaction and cost optimization. In particular, the importance of customer value is emphasized. Secondly, in order to promote the realization of the value of coal supply chain, coal combined transportation should follow the corresponding principles when choosing transportation mode and cooperative transportation. In the last part of the paper, an optimization model based on maximization of time value and minimization of cost is constructed to solve the problem of route selection in actual transportation. The simulation experiment is carried out. The optimization algorithm is used to solve the problem, and the feasible solution is obtained. It is verified that in the supply chain value concept, the relationship between space-time value satisfaction and transportation cost minimization is not completely conflicting. With this method, the problem of multi-node and multi-mode transportation optimization based on supply chain value is solved.
