摘　　要：将灰色关联投影决策法引入厂址选择方案评价,通过分析灰色系统中各因素之间的关联度,较好地了解各规划方案与最优方案的相似程度,并对规划方案与最优方案之间的相对误差和绝对误差两个方面进行比较.同时,采用离差最大化方法确定权重,克服了人为主观因素的影响,使得比选方案的选择更加公正合理,准确性得到了提高.最后通过实例说明了该模型理论简洁,可操作性好,能够为厂址选择综合评价提供科学合理的决策依据.The method of Grey Relation Projection is introduced for the evaluation of the site selection program.Through analysis of the degree of association between various factors in gray system,a better picture is provided about the degree of similarity between each plans and the optimal solution,and the relative error with the absolute error is compared.At the same time,weighting coefficients are determined by the method of maximizing deviations,which can overcome the subjective influence of decision-makers and make a fairer and more rational choice than the alternative.The accuracy has been improved.The example for illustrating the model theory is simple and easy to manipulate in providing a scientific and reasonable decision basis for the comprehensive evaluation of site selection.
