Methodologically, the geographic information system (GIS) is used to determine the optimum site for a solar power plant. It is intended to integrate the qualitative and quantitative variables based upon the adoption of the Fuzzy Analytic Hierarchy Process (Fuzzy AHP) and the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) model. These methods are employed to unite the environmental aspects and social needs for electrical power systematically. Regarding a case study of the choice of a solar power plant site in Thailand, it demonstrates that the quantitative and qualitative criteria should be realized prior to analysis in the Fuzzy AHP-TOPSIS model. The fuzzy AHP is employed to determine the weights of qualitative and quantitative criteria that can affect the selection process. The adoption of the fuzzy AHP is aimed to model the linguistic unclear, ambiguous, and incomplete knowledge. Additionally, TOPSIS, which is a ranking multi-criteria decision making method, is employed to rank the alternative sites based upon overall efficiency. The contribution of this paper lies in the evolution of a new approach that is flexible and practical to the decision maker, in providing the guidelines for the solar power plant site choices under stakeholder needs: at the same time, the desirable functions are achieved, in avoiding flood, reducing cost, time and causing less environmental impact. The new approach is assessed in the empirical study during major flooding in Thailand during the fourth quarter of 2011 to 2012. The result analysis and sensitivity analysis are also presented.展开更多

The 4,500-year old Egyptian pyramids at Giza are buildings to learn from. This paper tries to pin down the reasons for the survival of the Giza pyramids in order to reach a criterion for choosing sites for important buildings. It argues that the site selection and the geological properties of the area, being away from seismic effects,, floods and groundwater levels, the stability of the geometric form of the pyramid, the solidity of the structural engineering and precision of execution arguably are the reasons why the Great Pyramids of Giza are the only survivors of the seven wonders of the ancient world.展开更多

However, expansion of hydropower resources islimited, and with growing population and demand for electricity, the government of Uganda is considering integration of nuclearpower into its energy mix. With the current and projected grid capacity, SMR （small modular reactor） technology is attractive sincecapacity can be added incrementally. This paper therefore presents results for SMR site selection in Uganda. Starting with twentyregional areas established by the Ugandan government, a site selection process is outlined which uses four levels of screening andranking. First, exclusion criteria including seismicity, volcanic activity, water resources, and transportation distances were applied.This reduced the potential regional areas down to eight. Next, MAUT （multi-attribute utility theory） weighting was assigned to theseeight areas for： （1） distance to large population centers, （2） ease of transportation, and （3） distance to seismically or volcanically activeareas. From this ranking, four regional areas stood out and were then selected. These regions were then compared using variousattributes including access to water and integration with the developing national grid. In the final step, the lead candidate region wassubdivided into subzones to further refine the selection process.展开更多

Excellent operating indexes of the existing nuclear power plants and the capability of independent design, manufacture, construction and operation are briefly enumerated. There are over thirty nuclear power plant sites in the coastal and inland areas, which have been checked or preevaluated. This proves that a solid foundation for large-scaled development of nuclear power industry has been laid and nuclear power will certainly play an important role in power supply and environment protection of China.展开更多
