The work aims to analyze the future development direction of elderly-oriented design of community fitness center by the Soft Systems Methodology (SSM) of Peter Checkland, so as to provide important design strategies for communities to cope with dynamic aging. First of all, the concept of SSM was analyzed and the analysis process of its application in the elderly-oriented design of community fitness center was summarized. Secondly, based on the connotation of the elderly-oriented design of community fitness center, SSM was adopted to carry out problem situation perception expression and root element definition and classify the demands at the same time and discuss the conceptual model. By comparing the conceptual model with the real world, quantitative scoring was conducted to obtain the four-stage strategic goals based on equipment, spatial layout, intelligent interaction and emotional experience and the rational and universal conceptual model. Since SSM and elderly-oriented design share a common unstructured feature centered on human activities, it is of practical significance to use SSM to study the design problems with strong social characteristics such as the elderly-oriented design.
