Taking Fengyang Town of Fenxi County, Jiangxi Province for example, this paper applied Arc GIS to analyze natural facors, social economy, and construction factors quantitatively by evaluating development and construction conditions of each village comprehensively from the perspective of urban-rural integration. Classifying the villages into 4 types, namely urban reform type, concentrated development type, controlled construction type and relocation type, this paper tried to guide the scattered rural settlements to the intensive development.展开更多

Traditional layout methods can not fully solve this complex spatial layout problem. Virtual reality (VR) is a new form of human\|computer interaction, which has the potential to support a range of engineering applications. This paper discusses the reasons why manufacturing facility layout design is considered to be an appropriate new area of VR utilization. A VR\|based layout design framework is proposed. The virtual environment construction issues are discussed. An example of the immersive VR application of facility layout is examined.展开更多

This happens mainly because of a gap that exists between engineering and psychology fields, with the first developing planning tools for production but with little concern for creativity and the other developing spaces for creativity, but with a lack of tools. Both try to solve the same issue： fostering productivity in the workplace, but they need to be linked first, in order to accomplish it. How to close this gap？ Can a project manager plan the facilities for a creative organizational in the best way possible？ In this paper, a new approach is used for studying the design of physical environments that foster organizational creativity, combining the results of psychological studies on the impact of physical environment on creativity with the facilities planning body of knowledge applied by industrial engineers. In order to test the results, a single case study is developed in a small IT consulting firm. By using the systematic layout planning （SLP） step by step process, it is shown that by acting on the work environment of the company, the developers creative processes can be boosted and facilitated. It is also shown that both industrial engineering and creativity research have much to contribute to each other and future research topics in the field are presented.展开更多

By analyzing three cases of industry layout planning of Shenzhen, in particular the evolution of planning thoughts and the implementation effect of the plans, this paper argues that an effective industry layout planning should focus on studying the spatial requirements of industries and creating the suitable physical environment for industrial development instead of directly arranging the layout of various industries. Moreover, the implementation of the latest planning policy in Shenzhen proves that the industry space policies issued by the local government should be problem-oriented and be aimed to solve the practical difficulties in the innovative development.展开更多

The proposed approach binds a multi-agent topology finding system and an evolutionary optimization process. The former generates topology satisfied layouts for further optimization, while the latter focuses on refining the layouts to achieve predefined architectural criteria. The topology finding process narrows the search space and increases the performance in subsequent optimization. Results imply that the spatial layout modeling and the muLti-floor topology are handled.展开更多

Disassembly is one of the most important processes performed during the recovery of WEEE. The overall goal of disassembly is to maximize the retrieval of various metals and plastics contained in WEEE in order to reduce their negative effects on human health and environmental sustainability and to increase economic gains. This study aims to evaluate alternative layout configurations for WEEE disassembly systems （WDS）. In this context, various configurations were compared in terms of pre-defined performance criteria, such as the total number of disassembled WEEE and the total revenue from sales, using simulation models. The results of this study show that the perfomaance of a WDS was significantly affected by output transfer systems along with the specialization of operators on certain types of WEEE.展开更多
