2007-2017年西安市机动车排放特征研究

西安市机动车保有量的大量增长带来了交通尾气污染物和CO2的高强度、集中性排放,严重影响空气质量以及碳排放治理工作。因此,详细的机动车排放特征研究可以为减排措施的设定提供依据。本文研究了2007-2017年西安市不同车型、不同排放标准的车辆排放特征。研究发现:各种污染物中,CO2排放量增长最快,年均增长率为15.1%。大型客车和大型货车是NOx、PM2.5的主要来源,小型客车和大型货车是CO2的主要来源。随着排放标准的不断提高,2017年国0排放标准的车型对VOCS和CO的贡献率仅为2.7%和1.9%。对各种污染物进行归一化处理后发现,CO和NOx在机动车污染物中占比最高。     

多资源约束下船闸施工网络计划的仿真与优化

船闸施工量庞大、涉及资源多、各工序交错复杂,仅凭人脑经验很难站在全局的角度制定科学、精确的施工计划。在多资源约束下,对船闸施工网络计划仿真建模和资源均衡优化方法进行研究。在分析典型船闸施工流程设计和施工空间划分的基础上,建立典型船闸工程施工网络计划仿真模型和多资源约束下船闸施工网络计划"工期固定-资源均衡优化"的数学模型,设计相应的遗传算法,并通过实际工程进行验证。结果表明,此模型和算法可行、有效,解决了多资源限制下的船闸施工网络计划资源均衡优化问题,为船闸施工进度、资源以及成本管理提供科学有力的依据。     

Evaluating economic and environmental value of liner vessel sharing along the maritime silk road

The Belt and Road initiative is a novel exploration of China towards strategic collaboration with Eurasia countries to an extent of a larger scale with higher and deeper level of cooperation. To meet the growing global demand of transportation, increasing numbers of liner shipping companies collaborate and form alliances to share vessel capacity and reduce capital costs. Effective liner shipping vessel sharing is essential for the Belt and Road initiative in terms of building efficient maritime transport networks. In promoting environmental development, shipping companies are required to attain higher environmental standards. However, limited literature relates vessel sharing to environmental performance. This paper studies the impacts of liner vessel sharing from the economic and environmental perspectives. Two container allocation models are developed for the two scenarios: with and without vessel sharing. The carbon emissions in transportation are calculated under both scenarios. Numerical studies are carried out using services along the China-Indochina Peninsula Economic (CIPE) Corridor. Liner shipping companies could benefit from vessel sharing in terms of significant profit improvement. Vessel sharing could also benefit the environment by reducing the CO₂ emissions dramatically.     

Development of port service network in OBOR via capacity sharing: an idea from Zhejiang province in China

The ‘Silk Road Economic Belt and the 21st-Century Maritime Silk Road’ (One Belt One Road, OBOR) strategy initiated by the Chinese government has a significant impact on the business and logistics modes which involves Asia, Europe, Africa, and their adjacent seas. Many countries and ports are developing new strategies that are suitable for this economic environment. Compared with many ports in the world, the ports in Zhejiang province of China have a novel property. In addition to Ningbo-Zhoushan port, there are several other sea ports and river ports in that province. In this paper, we propose a concept of port service network that consists of a huge hub and multiple ports. Ports of small and medium sizes can share their capacities of different types of port service with the hub when the service capacities are integrated into the network. We develop a mixed integer nonlinear programming model to determine the optimal decisions in such a network with constraints on the budget to conduct integration. An optimization algorithm incorporated with a genetic algorithm is developed to solve large size problems. We provide managerial insights on the policies of government, including expanding port capacity, reducing fixed integration cost, and providing better financial condition.
