The Evaluation Research Of Old Community Renovation Based On Cloud Model

As urban development enters the stock era,the sustainable development and organic renewal of cities have attracted much attention.The renovation of old residential areas,as an important part of urban organic renewal,is crucial for improving the urban image and enhancing the quality of life for residents.However,it is found that the evaluation research on the effectiveness of the renovation of old residential areas is still insufficient,and there are few evaluation studies based on the perspective of owners,and as a direct stakeholder in the renovation of old residential areas,their satisfaction with the renovation effect of old residential areas will directly affect the sustainable development of the renovation of old residential areas.Therefore,this paper takes the renovated old community as the research object,and evaluates the effect of the renovation of the old community from the perspective of the owner.First of all,the concept of old community and owner is defined,and the content of the renovation of old community is clarified.Then,after reading a large number of literature related to the renovation of old communities at home and abroad and the relevant policies of domestic renovation of old communities,combined with Maslow’s hierarchy of needs theory and satisfaction theory,the evaluation index system of renovation of old communities was preliminarily constructed.Then,combined with the peopleoriented theory,the grounded theory is used to carry out the secondary identification of the index system.Finally,an evaluation index system for the renovation of old communities was constructed,including 6 criterion layer indicators,including housing renovation,community security guarantee,supporting facilities transformation,community environmental transformation,community management,recognition value and 24 index layer indicators.At the same time,in order to obtain more objective and accurate evaluation results,after a variety of methods comparison,the G1 method and the CRITIC method were selected to determine the comprehensive weight of each index,and a cloud model for the evaluation of the renovation of old communities was established.Finally,taking NL cells as an example,empirical analysis is carried out,and the traditional fuzzy comprehensive evaluation method is used to verify,and the calculation results are consistent,indicating the effectiveness and reliability of the evaluation method for the renovation of old communities based on cloud model.According to the evaluation results of the cloud model,it is concluded that the satisfaction level of NL community owners is "general satisfaction",combined with the specific situation of NL community transformation,the problems existing in NL old community renovation are analyzed,and suggestions are put forward to improve the effect of old community renovation according to the problems found in the field investigation and the feedback and suggestions of owners.
