Ur-banization strategic environmental assessment integration technology system (SEA-ITS) is composed of "3S" (RS, GIS and GPS), environmental expert system and environmental model system, coupling with appropriate SEA working process closely. In this paper, the structure and components of SEA-ITS are analyzed based on Chinese characteristics, meanwhile methods to fulfill the following system functions are discussed: urbanization SEA in-quiring, analysis, discrimination, assessment, prediction, decision-making and output. Moreover, methods and tech-nologies employed in different urbanization SEA hierarchies are summarized. As a case study, urbanization SEA-ITS is applied in Changchun City to solving complex real problems. Methods such as system dynamics and grey cluster are adopted to achieve the environmental impact assessment on the eco-industrial system planning. It is revealed that the system designed is capable of reflecting the dynamic behavior of eco-industrial system under different sce-narios, meanwhile accomplishing strategy optimization and supplying scientific reference. The 4th strategy, namely concerning on economy increase and its interaction with science, technology and environment progress, would have the best efficiency. Further, more attention should be paid to the secondary development of integration techniques and function modification system of urbanization SEA-ITS.展开更多

A new enterprise coming from merger is different from the one that come into existence. The strategy of new enterprise formed from merger is constituted through the integration of the strategy for each side. Strategy integration is the guide for the integration of other elements after merger, the way for enterprises to adapt the change of environment and the warranty for the enterprises to achieve strategy synergistic effect. Strategy integration of the merging-enterprises can be realized through several steps： preparation for strategy integration, readjustment to strategy, reorientation of the enterprise and effective communication with target enterprise in the course of carrying out the strategy.展开更多

For sustainable and dependable infrastructure management, it is important to assess railway capacity limitation from the point of view of infrastructure performance. However, the existence of numerous performance indicators often leads to diffused information that is not in a format suitable to support decision making. In this paper, we demonstrated the use of fuzzy inference system for aggregating selected railway infrastructure performance indicators to relate maintenance function to capacity situation. The selected indicators consider the safety, comfort, punctuality and reliability aspects of railway infrastructure performance. The resulting composite indicator gives a reliable quanti fication of the health condition or integrity of railway lines. A case study of the assessment of overall infrastructure performance which is an indication of capacity limitation is presented using indicator data between 2010 and 2012 for five lines on the network of Trafikverket （Swedish Trans port Administration）. The results are presented using cus tomised performance dashboard for enhanced visualisation,quick understanding and relevant comparison structure conditions for strategic management. This gives additional information on capacity status and limitation from maintenance management perspective.展开更多
