Hierarchy Process

The construction of more nursing homes has become one of the most needed pension services in China, and the issue of site selection is one of the most important steps in their construction. The problem of site selection for nursing homes is a complex system engineering problem that involves not only economic interests but also social interests. Due to the limitations of human thinking in the evaluation process, the evaluation value of a nursing home site might be an interval grey number. Moreover, the evaluation indicator system for nursing home locations is a two-layer system that has been neglected in the literature. Therefore, the fuzzy analytical hierarchy process is extended to a new grey approach, i.e., the grey analytic hierarchy process, which can solve the evaluation problems for a two-layer indicator system under an interval grey environment. By constructing a three-point interval grey number, grey evaluation criteria are given to obtain a judgment matrix for interval grey numbers. Definitions of the initial weights, nongreyness weights and integrated weights are proposed to find the best evaluation object. Finally, the effectiveness of the method proposed by this paper is verified by comparative analyses of other grey methods.

Hierarchy Process

The window glazing system provides comfortable living environment for residents and also exhibits the esthetics of architectural design. Its quality is dependent upon glass material selection; there are many factors determining glazing material selection, which might further affects the building safety and energy savings. An analytic hierarchy process (AHP) is used to analyze the trade-off of these impact factors. In the survey, both positive and negative impact factors on the glazing material selection are considered. The results, based on 40 expertise questionnaires, indicated that “performance”, in overall, was perceived to be most important core selection criterion for the green glazing material, but among all assessed items, “hazardous substance release” was concerned the most. The “appearance” was regarded as a minor factor in this analysis. In addition, BIPV alternative was also ranked in the first position regardless of criteria weight variations. The results provide valuable information for building material manufacturers, architects and interior designers in selecting glass material in their the glazing system.
