With reference to the experience of specific practice on strategic alliance in typical domestic and overseas port like New Jersey Port in New York, port of Kaohsiung, Keelung and Taizhong, major ports in Yangtze River Delta, the possible modes of Rizhao Port strategic alliance were proposed. Based on the previous analysis, specific design on the supply chain management system of Rizhao Port viewing from strategic alliance was given in this dissertation, which mainly covered two aspects. On the one hand, based on the overall review of common design process, structure design and selection of partnership of supply chain management, and with consideration of the development trend of Rizhao Port, the double-sector style supply chain structure mode of Rizhao Port was put forward based on strategic alliance. On the other hand, in order to make it more clear on the specific process and contents of this kind of supply chain structure, the specific implementation of five supply chain for Rizhao Port in which capital was taken as the hub were proposed, named as, the coal supply chain based on norm regular ship transport mode, the ironstone supply chain based on cost optimization, the crude oil transport supply chain with the aim of extending petrifaction industrial chain, the timber transport supply chain based on circulating economy concept, and the farming transport supply chain based on futures theory.

在前文分析的基础上，论文重点论述了基于战略战略联盟的日照港口供应链管理的总体框架构建和具体规划设计两方面：一方面，在对供应链管理一般构建流程、结构设计、供需均衡及合作伙伴选择等方面进行全面总结基础上，并结合日照港口的发展趋势，推出了基于纵向战略联盟的日照港口集团式双扇形供应链结构模型；另一方面，为进一步理清日照港口双扇形供应链结构中相关供应链的具体流程及内容，特提出了以资本为纽带日照港口五大供应链的具体设计，即基于准班轮运输模式的日照港煤炭供应链，基于成本最优化日照港口铁矿石供应链，以延伸石化产业链为目标的日照港原油运输供应链，基于循环经济理念的日照港木材运输供应链，基于期货理论的农业定单式日照港农业运输供应链。
