A location-allocation model for senior citizens communities planning

This study aimed at developing a location-allocation model for senior citizens communities planning. The developed model was applied to the case study of Wanhua District, Taipei City, to verify the applicability and reasonableness of model. The planning results of case study offer concrete recommendations to Taipei City Government. This study employed land-use suitability analysis and mathematical programming approach to design the model as a multi-objective mixed integer programming problem. The model considers three objectives for different stakeholders: maximizing environmental suitability, maximizing developed dwelling units and minimizing development costs, with the following constraints: upper and lower bounds of development scale for each site, dwelling unit demands and value ranges of decision variables. According to the model characteristics, this study applied ε-constraint method to solve the developed model.
