Identification of suitable areas for the presence of the elderly in urban areas using the AHP-Fuzzy model with emphasis on the environment-oriented psychology (Sample of Shiraz District 8)

Forecasts for the next 40 years predict an increase in the elderly population more than other age groups. Thus, the number of people aged 60 and over as a proportion of the world's population is projected to more than double, from 880 million in 2012 to 2 billion by 2050. The largest increase is projected in the 80-year-old class and above. The number of centenarians is growing even faster and is projected to increase tenfold, from approximately 343,000 in 2012 to 3.2 million by 2050. One of the groups that need further study in urban areas is the elderly group. In fact, moving towards urban adaptation for the elderly is a kind of movement towards urban sustainability. Accordingly, in this study, suitable spaces for the presence of the elderly with the approach of geriatric psychology using the AHP-Fuzzy model in the 8th district of Shiraz have been identified. Research method in this research in terms of results and consequences of research of a fundamental-strategic type and in terms of implementation process; Quantitatively and logically, reasoning is of the type of deductive research, and also in terms of time is part of cross-sectional research and in terms of purpose is analytical research. The statistical population includes the elderly of District 8, which is equal to 2477 people, and the sample size according to Cochran's formula is 285 people. The data used were collected using a questionnaire and connected to the fishnet network, and the AHP model was used for weighting, which had the highest weight in terms of physical environment and personal and social characteristics. After applying the obtained weight on the fuzzy maps, the layers were superimposed using the five fuzzy functions, which was selected as the final map according to the evaluation of the gamma function model to identify suitable places for the presence of the elderly.
