焦作市农地流转中的土地发展权配置研究

农地流转是优化土地资源配置,实现农业规模化经营发展,转移农村劳动力的主要途径,同时也是促进农村经济发展的主要手段。文章主要针对河南省焦作市现阶段农地流转中土地发展权合理配置进行简要实证分析,在阐述农地流转发展现状的基础上探讨焦作市农地流转中土地发展权配置问题及主要流转形式,通过调查等方式发现目前焦作市农地流转中土地发展权配置存在较大问题,如土地发展权主体不明确,缺乏法律体系保护、土地流转行为操作不规范、土地使用权主体间产权关系不清楚、缺乏土地产权价格体系等,并针对焦作市农地流转中的土地发展权配置问题提出完善法律制度,明确流转土地发展权收益;健全土地流转管理机制,保障农民土地发展权;以总量、结构、区域、时序配置实现土地发展权配置公平性等建议,以促进焦作市农地流转公平、公正地开展,为今后焦作市农地发展提供理论参考。     

Road accidents involving bicycles: configurations and injuries

This study analyzed the most common types of accident involving bicycles and compared the frequency of injuries. The data source was the database of German In-Depth Accident Study (GIDAS). Cases consist of bicycles and their riders involved in accidents between 2000 and 2010. In most collisions, the bicycle impacted with a car. The percentage of injured bicyclists was higher in collisions with a heavy vehicle and decreased when the bicycle impacted with lighter vehicles. A high percentage of injured bicyclists in single accidents was observed; the most severe injury was more frequently to head and extremities. Accidents involving a car and a bicycle with the right of way in a bicycle path represented about 20% of involved and injured bicyclists. The ten most frequent configurations represented about 60% of involved and injured bicyclists. These results contribute to understand the dangerous scenarios for bicyclists and to suggest preventive actions.     

Concurrent design of product family and supply chain network considering quality and price

We study the problem of concurrent design of a product family and its supply chain (SC) network. Inspired by a real-life case in computer industry, the impact of quality and price in SC demand is investigated. Two different models are proposed, the former maximizes the company’s profit with respect to customers’ priorities on quality and price; the latter is a bi-objective programming, which consider two extreme customer groups: for one group quality has the highest priority and for the other price; the intermediate groups falls between these two. The performance of the models is analyzed through a case problem.

Multi-criteria decision-making for complex bundling configurations in surface transportation of air freight

Airlines typically carry out freight transportation in a hub and spoke structure, where the movements between the outstations and the hub are served by trucks. To transport freight efficiently, air carriers must consider bundling options for shipments that are delivered at outstations and have to be moved to the hub. There are three options when it comes to bundling freight: on ‘through unit load devices’ (T-ULD) (all freight for the same flight at the hub), on ‘mixed unit load devices’ (M-ULD) (freight for different flights at the hub) and loose freight in trucks. The optimal freight bundling configuration for carriers, taking into account their main KPIs (key performance indicators), is unknown. This research formulates the problem as a multi-criteria decision-making (MCDM) problem, allowing carriers to decide which configuration is optimal for a given outstation. The selected KPIs (cost, (un)loading time, and quality) are formulated as mathematical functions. A new MCDM, called best worst method (BWM), is then used to identify the best configuration with respect to the three KPIs. The proposed methodology is applied to KLM Cargo to identify the best configuration for the selected outstations that supply freight to the KLM hub at Schiphol Airport. This case study shows that there are different optimal freight bundling configurations for different outstations and that trucking costs and freight handling tariffs are among the key factors in deciding which configuration is optimal.     

人才资源的行政配置与市场调节

通过思辨方法研究表明,人才生产力提高需要发挥市场机制和党政机制的共同作用.市场与政府在人才资源配置中具有明确的职责边界.人才的开发、配置和使用需要在市场机制基础性作用下,发挥党和政府在人才战略规划、发展方向、政策激励、环境建设和法律保障等方面发挥主导作用.     

开发流程优化模型实行科学量化决策--全面提升股份公司战略研究、资源配置水平和公司价值

石油石化行业是一个需求和价格的波动幅度都比较大且比较频繁的行业，传统的局部测算工具已经无法适应大型炼化一体化石油公司的整体业务链运营。重组后的中国石油实现了上下游、产供销、内外贸一体化的运营格局，迫切需要科学、量化的决策辅助工具来合理解决资源配置、炼化生产与市场布局的优化问题。大型线性流程优化模型系统立足中国石油总部层面，涵盖了141种原油、69个炼厂、31个成品油销售市场，可对进口原油油种、国内资源配置、成品油流向等进行优化设置。优化模型系统经过进一步的功能拓展还可实现影子价格分析、瓶颈因素分析，能为大型投资项目、战略规划等提供量化的辅助决策依据。     

A Fourth Desideratum: The CES Cost Function and the Sustainable Configuration of Multiproduct Firms

For many parameter vectors, the sustainable configuration of an industry where multiproduct firms have CES cost functions fails to imply the existence of a multiplicity of multiproduct firms.
