Constructing a synthetic evaluation system of hospital out-door environment based on analytic hierarchy process and fuzzy synthetic evaluation

Abstract

The landscape has a supporting role to the medical effect. A synthetic evaluation system on out-door environment should be constructed through scientific and quantitative methods to build hospital outdoor environment which helps patients recover. Taking 5 first-class general hospitals in Nanjing as research subjects, the research used the methods of Analytic Hierarchy Process and the Fuzzy Synthetic Evaluation to construct synthetic evaluation system of hospital out-door environment. The results indicated that functional indicators were the most important, among which the environmental safety indicator had the highest weight value of 0.456 6. Among the suitability indicators, 'soft' elements such as acoustical environment, wind environment and luminous environment had high weight values which were 0.365 0, 0.255 3 and 0.182 9 respectively. In ornamental indicators, green looking ratio had the highest weight value of 0.532 7, much higher than other indicators. Based on the above synthetic evaluation system of outdoor environment, the research obtained grade levels of outdoor environment quality of the sample hospitals, which showed that outdoor environmental quality of the general hospitals in Nanjing was relatively low. The research showed that quantitative and synthetic evaluation system was more scientific and objective in out-door environment evaluation, and therefore provided a significant reference for the construction of hospital outdoor environment.
