The changing role of ports in supply-chain management: an empirical analysis

As integrated supply-chain management (SCM) is now at the epicentre of business transformation, firms are breaking down boundaries between internal functions, as well as between the enterprise itself and key partners in the value chain (e.g. customers, distributors, suppliers and carriers). One of the main goals of such new management approach is to get everyone in the supply chain into a common platform of logistics transactions and information systems.

Against such background, the aim of this work is to analyse how and if port operators can face the challenge of higher integration, on the assumption that the higher the integration between the actors the higher the competitiveness of the whole supply chain.

Accordingly, we adopted an SCM approach in the analysis of the port of Le Havre in Renault's supply chain. More specifically, we referred to the Lambert tri-dimensional model based on supply chain's structure (actors), key business processes and links between actors. The field work—which mainly consisted of semi-structured interviews to Renault, logistics and port operators, and, finally, to the Le Havre Port Authority—was crucial to gather the needed information.

旁靠系泊油船水动力相互作用分析

为了研究多浮体水动力相互作用下的波浪载荷和船体响应,针对旁靠系泊的穿梭油船与FPSO进行模拟计算。其中二阶波浪力采用近场方法求解。计算分析发现,由于屏蔽效应的影响,穿梭油船上的波浪绕射力受水动力相互作用的影响较大,平均二阶波浪漂移力在波频的高频段受水动力相互作用影响显著,在低频段几乎不受影响,而附加质量和辐射阻尼以及船体响应的RAO受影响则较小。另外,随着穿梭油船与FPSO相对距离的小范围变化,水动力相互作用的影响并没有太大的差别。
