【摘要】：针对传统工业总图设计方案中优选方法的不足,结合总图布置自身的特点,构建总图设计方案的评价指标体系;将灰色关联投影决策法引入到工业总图设计方案评价中,借鉴TOPSISI思想将理想方案作为设计方案的参考点,应用灰关联分析法从理想方案和设计方案的相对误差和绝对误差两个方面进行比较,计算出各设计方案和理想方案的相似程度;同时采用离差最大化的方法确定评价指标权重,克服人为主观因素的影响,使得方案的比选更加科学、客观、合理;最后运用该模型进行实例分析评价,得出评价结论.结果表明,该模型理论简单、可操作性好,具有很好的实用性,可为工业企业总图设计方案评价提供科学合理的决策依据.
[Abstract]:In view of the deficiency of the optimal selection method in the traditional industrial general plan design scheme, the evaluation index system of the general plan design scheme is constructed according to the characteristics of the general plan layout, and the grey correlation projection decision method is introduced into the evaluation of the industrial general plan design scheme. Referring to the idea of TOPSISI, the ideal scheme is regarded as the reference point of the design scheme, and the relative error and absolute error of the ideal scheme and the design scheme are compared by using the grey relational analysis method, and the similarity degree of each design scheme and the ideal scheme is calculated. At the same time, the method of maximization of deviation is used to determine the weight of evaluation index, to overcome the influence of human subjective factors, and to make the scheme selection more scientific, objective and reasonable. Finally, the model is used for case analysis and evaluation, and the evaluation conclusions are obtained. The results show that the model has the advantages of simple theory, good maneuverability, good practicability, and can provide scientific and reasonable decision basis for the evaluation of the general plan design scheme of industrial enterprises.
