基于“前港后厂”模式的进口铁矿石采购物流成本优化

作为钢铁产量大国，国内铁矿石资源品位低、开采难度大、选矿成本高，需要大量进口国外优质铁矿石，导致钢铁企业采购物流成本居高不下；长期大批量远距离的铁矿石海运历史，促使了我国"港-钢"企业的发展紧密相连。因此，本文基于"前港后厂"模式，构建了以船型、供应商和接卸港的选择为变量，以最小化铁矿石采购物流成本为目标的组合优化模型。运用免疫遗传算法和MATLAB进行求解与仿真验证，结果表明"前港后厂"模式较传统模式在优化采购物流系统上更优，为推行"前港后厂"模式提供了理论依据。

刘弘功业试论

明末清初之际的大思想家王夫之在其著名的史论著作《读通鉴论》中谈到"晋保江东以存中国之统,刘弘之力也。……微弘,则琅琊南迁,王导亦无资以立国。"刘弘作为西晋末年的重臣,不溺陷于八王之乱的纷争厮杀之中,而是端持正道,保境安民,尤其是平治荆州、江南地区的战乱,并选贤任能,协调南北,为后来琅琊王司马睿的南迁奠定了基础,不愧为社稷之臣。     

港口竞争中连云港港口发展格局研究

统计分析1999年至2008年连云港港口发展与临港城市经济,与日照港口发展与临港城市经济的地区差异,研究发现,临港城市经济与港口发展具有相同的变化趋势,近些年,日照的港口发展与港城经济都要快于连云港的港口发展与港城经济。在港口竞争中,连云港港口发展面临着巨大的压力。文章提出了一些提升连云港港口竞争力的政策与建议。     

Maritime Transportation Risk Assessment of Tianjin Port with Bayesian Belief Networks

This article develops a Bayesian belief network model for the prediction of accident consequences in the Tianjin port. The study starts with a statistical analysis of historical accident data of six years from 2008 to 2013. Then a Bayesian belief network is constructed to express the dependencies between the indicator variables and accident consequences. The statistics and expert knowledge are synthesized in the Bayesian belief network model to obtain the probability distribution of the consequences. By a sensitivity analysis, several indicator variables that have influence on the consequences are identified, including navigational area, ship type and time of the day. The results indicate that the consequences are most sensitive to the position where the accidents occurred, followed by time of day and ship length. The results also reflect that the navigational risk of the Tianjin port is at the acceptable level, despite that there is more room of improvement. These results can be used by the Maritime Safety Administration to take effective measures to enhance maritime safety in the Tianjin port.     

Supply Chain Vulnerability Analysis Using Scenario‐Based Input‐Output Modeling: Application to Port Operations

Disruptive events such as natural disasters, loss or reduction of resources, work stoppages, and emergent conditions have potential to propagate economic losses across trade networks. In particular, disruptions to the operation of container port activity can be detrimental for international trade and commerce. Risk assessment should anticipate the impact of port operation disruptions with consideration of how priorities change due to uncertain scenarios and guide investments that are effective and feasible for implementation. Priorities for protective measures and continuity of operations planning must consider the economic impact of such disruptions across a variety of scenarios. This article introduces new performance metrics to characterize resiliency in interdependency modeling and also integrates scenario‐based methods to measure economic sensitivity to sudden‐onset disruptions. The methods will be demonstrated on a U.S. port responsible for handling $36.1 billion of cargo annually. The methods will be useful to port management, private industry supply chain planning, and transportation infrastructure management.
