鲜活农产品物流管理与运作分析

由于鲜活农产品的时效性、分散性,目前国内很少对这类产品物流进行系统研究;鲜活农产品物流的合理发展不仅促进农民经济收入,而且有效引导农村剩余劳动力转移。以寿光市蔬菜物流中心为例,分析了鲜活农产品物流现状和特点,提出了鲜活农产品物流运作模式,同时也为山东省发展农产品物流运作模式提出了建议。

利用地下空间助力发展绿色建筑与绿色城市

当今世界,绿色发展已经成为一个重要趋势,绿色发展理念更是指导我国“十三五”规划的重要理念之一。建设城市地下空间是转变城市发展方式、治理“城市病”并建设绿色城市的主要着力点。首先,说明绿色建筑与绿色城市的概念,以及二者的关系。重点从节约土地、利用地热能、节水、绿色城市基础设施（包括绿色客运城市交通和城际交通,未来城市货运交通,绿色城市污水、雨洪蓄排系统,绿色城市垃圾集运和处理系统,智慧地下综合管廊,城市智慧行车系统）等方面,并结合国内外典型案例分析说明利用地下空间发展绿色建筑和绿色城市的理念、方法、构想。最后,结合实例强调地下空间开发规划的重要性、规划科学的重要性、开发与规划中的问题及规划的具体要求。     

Effects of the ‘Belt and Road’ initiative on the wine import logistics of China

China’s Belt and Road (BR) initiative is expected to facilitate international trade between the countries involved. In this study, we review the special requirements of wine logistics and the market growth potential of wine consumption in China. A model minimizing generalized logistical costs is developed and applied to wine imports in China, so that the best candidate cities in which to locate transport gateways and distribution centers can be identified. Our analysis suggests that the most preferred gateways are Shanghai, Tianjin, Guangzhou, and Hong Kong, which all have similar delivery costs. In comparison, Beijing and Chongqing have much higher delivery costs, mainly because they do not have good access to marine transport and/or efficient domestic distribution networks. For long-distance intercontinental transport of large volumes of wine, marine shipping remains the only viable delivery mode. However, wine distribution within China extensively uses air, road, and water transport. Therefore, cities with excellent multi-modal transport services are better positioned to become wine logistics gateways. Our study also highlights the importance of value-added services and good government support, which are important factors that influence distribution costs and quality.     

Methodology for ro-ro ship and fleet sizing with application to short sea shipping

A novel methodology is developed for determining the characteristics of a cargo roll-on/roll-off (ro-ro) ship and the fleet size required for a given short sea shipping route. The ship and required fleet size to satisfy the transportation demand (for each pair of speed and freight rate) are determined using a database of existing cargo ro-ro ships to obtain the main technical characteristics of the most suitable ship. The time charter, voyage costs and revenue are then calculated considering the technical characteristics of each ship. Fuel costs are corrected for the actual ship speed and loading condition. A number of restrictions in the transportation problem are considered leading to the exclusion of unfeasible solutions. The maximum profit over the period of a year is identified among the feasible pairs of speed and freight rate. This general methodology is applied in a case study that considers the route between Leixões (Portugal) and Rotterdam (Netherlands). The study allows the identification of the most suitable ship and fleet sizes for different market penetration levels and quantifies the impact on shipping company profit of changes in parameters such as fuel costs, time charter costs, emission control area, installed propulsion power and stacking factor.
