| With the development of social economy,the livelihood problem of rural residents "housing to live" has basically been solved.However,due to the lack of management,lack of housing knowledge,and backwardness of concepts and technologies,the quality of rural housing needs to be improved urgently.Discussing how to improve the quality of the project requires considering the construction cost as an important premise.Studying the quality evaluation system and evaluation methods of rural housing and constructing a quality-cost optimization model will help to summarize the typical problems in the process of rural housing construction in a timely manner,clarify the quality evaluation standards of rural housing,and provide theoretical support for exploring the construction of economic and high-quality rural housing..Through combing existing research and investigating rural housing in Yunnan Province,a rural housing quality evaluation system has been constructed.Based on the analysis of the construction cost composition of rural housing,the relationship between housing quality and cost is discussed,and a housing quality-cost multi-objective optimization model is established.The rural houses in X town of Dali prefecture and M town of Banna prefecture were selected as the research locations,and empirical research on the quality evaluation and quality-cost optimization of rural houses was carried out.The research results of this article mainly include the following: Based on the current existing research and the survey of the current situation of rural housing in Yunnan Province,this paper studies the quality evaluation of rural housing,and builds a rural housing quality evaluation system and matching quality evaluation methods.Based on the analysis of the construction cost composition of rural housing,the relationship between the quality and cost of rural housing is discussed,and a housing quality-cost optimization model is established.And take the rural houses in X town of Dali prefecture and M town of Banna prefecture as examples to conduct empirical research on the quality evaluation and quality-cost optimization of rural housing.The research results of this article mainly include the following:(1)Establish a quality evaluation system for rural housingAnalyzed the connotation and extension of the quality of rural housing,summarized and sorted out the characteristics and construction models of rural housing in Yunnan.A rural housing quality evaluation system was constructed from the two dimensions of technical compliance and functional improvement.In order to determine the scientific and objective index weights and evaluation levels,the weighting method of the entropy weight method modified order relationship analysis weighting(G1)method is proposed to calculate the index weights,and the cloud model is used to calculate the survey data,and finally according to the membership degree of each index to determine the final evaluation level.(2)Constructing the quality-cost optimization model of rural housingThe cost composition of housing construction in villages and towns was studied,and a rural housing construction cost accounting table was established from three aspects: personnel,materials and machinery.With the help of SPSS software,input the project’s quality index scores and corresponding cost data into the software,and use the principle of least squares to fit the cost-cost regression equation.Based on conditional assumptions and operational research theory,a quality-cost multi-objective optimization model is constructed.(3)Empirical research on rural housing quality evaluation and quality-cost optimizationIn order to verify the feasibility and effectiveness of the evaluation system and the housing quality-cost optimization model,Town X in Dali Prefecture and Town M in Xishuang Banna Prefecture were selected as the research areas.Comprehensive evaluation and optimization analysis were carried out based on the evaluation methods selected in the paper and the optimization model constructed,verified the correctness and operability of the evaluation method and model,and put forward the optimization suggestions for the construction and implementation of rural houses based on the evaluation results. |
