At present, it is difficult to fully cover the actual needs of use in the actual renovation planning of old residential areas, which affects the implementation of the renovation. In order to improve the quality of renovation planning for old residential areas, a method based on the demand priority model was studied and designed. The process of establishing a model includes two aspectscontent system and requirement priority decision-making method system. A specific list of transformation contents was constructed, expert interviews were conducted to improve the rationality of the transformation contents, and a decision-making system was proposed. The corresponding original decision matrix calculation method was established. When carrying out renovation planning, first identify the requirements and collect data, then build a model and classify it, and calculate the score to rank the requirements. The experimental results show that in the four quadrants established by the model, when the importance score is below 3.75, the various indicators are mainly located in quadrant 2. When the importance score exceeds 3.75, most indicators are located in the priority improvement zone, and a few indicators are located in the over concern zone and the lower value zone. The maximum distance between the transformation requirement and the positive ideal solution is 0.677 and 0.691, the minimum is 0.069 and 0.062, and the final score is 0.909. The research method can effectively assist in the planning of community renovation, and theoretically has high rationality and practicality in practical applications.
