摘要
目的利用数据包络分析模型对农房适用墙体砌块材料指标中经济性的投入、技术性输出、环境的定量问题进行有效性评价,选出最优的农房适用墙体砌块材料,提高农房建筑整体质量.方法综合分析了农房适用墙体砌块材料各影响因素,提出了一套综合评价指标体系,构建了基于数据包络分析的农房适用墙体砌块材料选择模型.将该模型用于五种具有代表性农房适用墙体砌块材料的评价.结果通过实例证明了该模型在农房适用墙体砌块材料选择方面的有效性.数据包络分析为新型农房适用墙体砌块材料的选择、推广提供了准确、合理的理论依据.结论评价结果表明,数据包络分析法能够客观评价农房适用墙体砌块材料优选中的可行性和合理性.为决策过程提供了数据支持,使决策工作更加简单明了.
Evaluating the economy input, technology output and environment quantification of block wall ma- terials of rural housing using DEA model, this research aims to choose the optimal block wail materials of rural housing to improve the quality of the building. This research puts forward a set of comprehensive evalua- tion index system based on the analysis of all the factors of reasonable block wall materials of rural housing, and builds a model of selecting the reasonable block wall materials of rural housing based on DEA. The research then uses the model to evaluate five kinds of representative block wall materials of rural housing and it has been proved by examples that the model is effective on selecting block wall materials of rural housing. DEA provides accurate and reasonable theoretical basis for the selection and promotion of reasonable block wall materials of rural housing. The evaluation results show that DEA can objectively evaluate the feasibility and rationality in the process of selecting reasonable block wall materials of rural housing, provide data support for decision process and make the work of decision making more simple and clear.
