Parameter Simulation on the Control Strategy for a Parallel Hybrid Electric Vehicle by CRUISE

The purpose of a parallel hybrid electric vehicle(PHEV) is for the best energy distribution between internal-combustion engine(ICE) and electric motor though the appropriate control strategy.It can not only keep the advantage of the ultra-low emission of electric vehicles(EV),but also take advantages of the hyperbaric energy of ICE.Simulation model for PHEV is built based on CRUISE,an auxiliary control strategy is designed,and then parameter simulation study on the control strategy is performed.The simulation results show that according to the different control requirements,the vehicle performance can be improved by adjusting!the corresponding control parameters.     

Model of Survivable Architecture

Critical information system in Interact is in face of increasingly security problems. More attention has been focused on the survivability of information system, which is the capability of system to continue its mission even in the presence of damage to the system. The authors first introduce the definition of survivability. According to four function properties of survivability, which are Resistance, Recognition, Recovery, and Adaption, the authors design a model of survivable system structure and then explain survivability requirement, survivability strategy in this model. Additionally, they provide possible technical solutions for the survivability of systems, categorized by different aspects of our survivability strategy.     

Exploration of Implementation Strategieson Housing Building Technology

Due to the sharp contradiction between rapidly developing housing construction in small-size town and quite low technological level, in this paper, the significance of setting up integrally technological system is emphasized and the suggestion that the technology should be integrated with the sustainable development, regional context and industrialization is put forward.     

Appropriate Technology and Corresponding Design Strategies for the Steel Construction Congregated Apartments

In this paper,notions on appropriate technology for the Steel Construction Congregated Apartments are proposed in order to deal with the technical impediment that arises from applying steel structural techniques to the congregated apartments.The appropriate technology for the steel construction congregated apartments is defined as systematic technologies that are in harmony with the status quo of Chinese productive force level,social culture and building technology,and as the strategies of choosing or balancing technology according to sustainable development principle.The principal design and constructing strategies of appropriate technology are as follows:(1) organization of residential space combined with steel construction techniques,(2) suitable structural system,(3) a new idea of fire resistance,and(4) kit building technique etc.A technological concept analysis about an ideal model of a steel construction system congregated apartment combined with the appropriate technology is also presented.     

制动状态下的AMT换挡策略

根据车辆动力学及发动机辅助制动特性研究了制动状态下AMT自动换挡策略。研究了高强度制动状况下在挡辅助制动对前、后轴利用附着系数的影响，获得了符合相关国家标准的换入空挡的临界车速。中强度持续制动可以识别为下长坡的运行工况，定义了辅助制动的等效制动强度，在分析试验数据的基础上给出了根据制动强度和车速2个参数的主动降挡辅助制动换挡规律。     

A model of decision-making and information flows for information-intensive agriculture

This paper describes the development of a systems based model to characterise farmers’ decision-making process in information-intensive practices, and its evaluation in the context of Precision Agriculture (PA). A participative methodology was developed in which farm managers decomposed their process of decision-making into brief decision statements along with associated information requirements. The methodology was first developed on a university research farm in Denmark and further revised during testing on a number of research and commercial farms in Indiana, USA. Twenty-one decision-analysis factors were identified to characterise a farm manager’s decision-making process. Then, a general data flow diagram (DFD) was constructed that describes the information flows “from data to decision”. Illustrative examples of the model in the form of DFDs are presented for a strategic, a tactical and an operational decision. The model was validated for a range of decisions related to operations by three university farm managers and by five commercial farmers practicing PA for cereal, corn and soybean production in Denmark and in Indiana, USA.

山东农机制造业集群化发展战略研究

山东省是农业大省,也是农机大省,无论是农业机械化水平,还是农机制造业水平都位具全国首位,在全省乃至全国制造业中扮演着重要角色。本文从企业集群化发展战略管理理论的分析入手,对山东省农机制造业企业的现状进行了研究,总结了国内外企业集群发展的成功经验,理论与实践相结合,提出了可供借鉴的集群发展模式和相应的对策建议。     

基于投入产出模型的MICK-4FI模式研究

波特竞争战略侧重从外部行业环境角度解释企业运营问题,但是实证分析结果证明资源对企业发展影响重大。针对目前尚无具体模式研究企业如何立足现有资源进行发展问题,本文基于资源基础论,将企业资源具体分为物质、信息、资金和知识资源(MICK),提出了MICK-4FI(四流集成)资源运营模式,借助投入产出模型构建MICK-4FI模式分析框架。文中利用聚焦和杠杆作用定性地解释了企业培育或者集成资源,即企业获取资源形成竞争优势的机理。本模式将资源基础论应用到企业实践层次,解决了企业通过集成运营内外部资源以求快速发展的路径依赖问题。资源运营理论从微观资源角度分析企业经营,与波特从宏观行业分析的理论共同构成一套系统的企业运营理论体系。
