【摘要】：随着经济全球化的步伐不断加快、科技进步和管理技术创新,物流业已经进入到供应链时代。港口之间的竞争已经演变为港口所在的供应链之间的竞争,因此,港口必须构建一个健全、高效的港口供应链网络体系,通过港口供应链的发展来应对不断变化的市场,扬长避短,维持自身竞争优势。为促进港口供应链的构建和实现港口供应链的优化,本文进行基于多Agent系统港口动态供应链优化研究,以期为港口及相关物流企业发展提供参考。根据供应链管理思想、港口在港口供应链中的功能和作用以及港口供应链的特征,本文明确了港口动态供应链的概念。同时分析了港口动态供应链不同于制造型供应链的特征,并论证了应用多Agent系统进行供应链优化的可行性及有效性。在明确了使用多Agent系统进行供应链优化的可行性后,本文从两个方面着手进行港口动态供应链优化研究,即港口动态供应链伙伴选择和港口动态供应链协同。首先,采用改进的合同网协议进行港口动态供应链伙伴选择。针对传统合同网协议的不足,本文提出了基于信任度评价的招标策略、基于能力可用度的投标策略以及基于DCOP的评标策略等改进方法,并应用于港口动态供应链伙伴选择。其次,本文分析港口动态供应链协同形成机理,并设计了包括信用机制、信息共享机制、利益分配机制、风险防范机制以及反馈机制的协同实现机制,保障港口动态供应链协同的顺畅运行。最后,本文以深圳港为例进行案例分析。通过对实际案例的分析,详细剖析了港口动态供应链优化的过程及方法。实例优化结果说明本文提出的方案是可行、有效的。
[Abstract]:With the accelerating pace of economic globalization, scientific and technological progress and management technology innovation, the logistics industry has entered the era of supply chain. The competition between ports has evolved into the competition among the supply chains in which the ports are located. Therefore, the port must construct a sound and efficient network system of the port supply chain to cope with the changing market through the development of the port supply chain. Develop strengths and circumvent weaknesses and maintain their own competitive advantages. In order to promote the construction of port supply chain and realize the optimization of port supply chain, this paper studies port dynamic supply chain optimization based on multi-Agent system, in order to provide reference for port and related logistics enterprises. According to the idea of supply chain management, the function and function of port in port supply chain and the characteristics of port supply chain, this paper defines the concept of port dynamic supply chain. At the same time, this paper analyzes the characteristics of port dynamic supply chain different from manufacturing supply chain, and demonstrates the feasibility and effectiveness of applying multi-Agent system to supply chain optimization. After making clear the feasibility of using multi-Agent system to optimize supply chain, this paper studies port dynamic supply chain optimization from two aspects, namely, port dynamic supply chain partner selection and port dynamic supply chain cooperation. Firstly, the improved contract net protocol is used to select port dynamic supply chain partners. In view of the shortcomings of traditional contract network protocols, this paper puts forward some improved methods, such as bidding strategy based on trust evaluation, bidding strategy based on capability availability and bidding evaluation strategy based on DCOP, which is applied to the selection of port dynamic supply chain partners. Secondly, this paper analyzes the cooperative formation mechanism of port dynamic supply chain, and designs the cooperative realization mechanism including credit mechanism, information sharing mechanism, benefit distribution mechanism, risk prevention mechanism and feedback mechanism. Ensure the smooth operation of port dynamic supply chain coordination. Finally, this paper takes Shenzhen Port as an example to carry on the case analysis. Through the analysis of practical cases, the process and method of port dynamic supply chain optimization are analyzed in detail. The optimization results show that the proposed scheme is feasible and effective.
