Intelligent scheduling model and algorithm for manufacturing

This paper puts forward an intelligent scheduling model based on Hopfield neural network and a unified algorithm for manufacturing. The energy computation function and its dynamic state equation are derived and discussed in detail about their coefficients (parameters) and steps (Delta t) in iteration towards convergence. The unified model is focused on the structure of the above function and equation, in which the goal and penalty items must be involved and meet different schedule models. The applications to different schedule mode including jobshop static scheduling, scheduling with due-date constraint or priority constraint, dynamic scheduling, and JIT (just in time) scheduling are discussed, and a series of examples with Gantt charts are illustrated.

新能源时代中国应对美国“301调查”策略研究

美国针对中国新能源产业的“301调查”,实质是在旧有国际经济秩序暂难破除、国际新能源秩序尚未形成和多边体制威力衰落的共同影响之下,“南北矛盾”在新能源产业上的新表现。中国应“内外兼修,长短兼顾”,对外坚持构建国际经济新秩序的努力,发挥在国际新能源秩序建立过程中的主导作用,维护和推动多边体制的有效运转;对内通过完善产业发展制度,调整新能源结构,制定竞争性补贴政策,加强新能源产业行业协会建设等作以策应。     

日本《低碳投资促进法》述评

日本参议院于5月18日通过了《低碳投资促进法》,该法是日本建设低碳社会的最新立法,规定了对从事适合能源环境的制品开发与制造的特定事业者提供筹资支持,需求开拓支援法人承保租赁合同等措施,对我国的相关立法有一定的借鉴意义。     

生命力的赞歌——论劳伦斯变异的人文主义在《查泰莱夫人的情人》中的表现

D.H.劳伦斯希望通过恢复男女两性关系的自然性来拯救危机四伏的西方社会,在他的作品里充满了对生命力的赞美。他这一思想与西方传统的“人文主义”思想很相似,却并非完全相同,这一思想可称为变异的“人文主义”思想,他的这种思想集中表现在《查泰莱夫人的情人》中。     

中国国际能源合作若干问题论析

改革开放以来,我国对外能源战略实施历经着重引进西方资金技术的"引进来"开放、开拓海外能源市场的"走出去"国际化经营以及新能源安全观指导下全面多元的国际能源合作三阶段.当今中国的国际能源合作呈现出令人注目的新特征,包括能源合作对象与方式的多元化、合作渠道和路径的长期化和机制化,以及平等互利、共同受益的合作原则和价值取向;但同时面临西方国际竞争的压力、"中国威胁论"的危害、资源国合作环境的不利和周边国家的同构竞争与领土资源争议等一系列现实与潜在的严峻挑战和障碍.经济全球化的推进、全球金融危机的冲击也为我国互惠共赢的对外能源合作带来新机遇.     

中俄两国合作开发西伯利亚与远东地区的重要意义

能源项目作为现代工业和新经济发展的基础和动力,业已提到中俄两国经贸合作务实启动的日程上来,中俄两国合作开发西伯利亚与远东地区能源项目不仅对于双方是互惠互利的,而且是有利于提高双方合作水平,推动两国实现经贸合作的战略升级目标,促进两国在政治上战略协作伙伴关系的有效途径。     

The energy and mass balance of Los Angeles County

We conducted an urban “metabolic” study of inputs and outputs of food, water, energy, and pollutants from Los Angeles County, USA. This region has been the subject of recent debate about the nature of population density and distribution as it relates to urban form and associated environmental impacts. We found that with the exception of food imports and wastewater outputs, inputs of resources and outputs of pollutants generally declined on a per capita basis from 1990 to 2000. Reductions likely reflected a combination of changes in public policy, improvements in technology and public infrastructure, and impacts of increases in population density. However, in comparison to other municipalities and urban regions, resource consumption per capita was still relatively high in some categories, particularly inputs of water and transportation energy. Per capita greenhouse gas emissions were lower in Los Angeles County than for the average of the USA as a whole but higher than previous analyses of urban areas internationally, largely due to comparatively high emissions from the transportation sector. Wastewater discharge accounted for less than 40% of water inputs excluding precipitation; however the partitioning of water outputs through other potential losses, specifically evapotranspiration, runoff, and groundwater recharge, remains highly uncertain. We suggest that more detailed information about water losses will greatly improve future mass and energy accounting for analyses of urban environmental sustainability in this semi-arid region.     

中俄能源合作中的问题及对中国的影响

因“安大线”方案搁浅中俄能源合作面临了严峻挑战,两国对地区能源合作的利益诉求是决定双方合作的动机和关键因素。但在中俄能源合作中,日本扮演了第三方竞争角色,中俄日能源三角关系中将呈现出不同的合作模式,但其经济依存关系将导致三方既合作又竞争。俄大打石油王牌旨在提升其国际地位与作用,其奉行的外交策略将会导致中日之间对俄罗斯能源的竞争趋势。中俄能源合作中依然存在着一系列不确定因素,对双方的合作前景将产生影响。西方大国势力对俄罗斯石油资源的觊觎和争夺将加剧中俄能源合作面临的挑战。为此,中方应该充分发挥两国关系中的合作优势潜力,采取有效措施,协调与俄罗斯的利益差异,理顺双方经贸合作关系。
