检查评比是搞好公共场所卫生管理的重要手段。传统的检查评比多采用总分法来进行各单位间的比较,其弊端是工作重点不突出,给管理工作带来不便。本文采用加权平均法进行评比,以求克服这一缺点。1 数学模型若评判对象有m个因素,对每个因素评定所得的分数为Si。因对每个因素重视程度不同,所以可按其程度对每个因素赋以一定的权Pi,Pi表示第i个因素在评判中占的百分比。可用下面公式作为评判的数学
Inspection and evaluation is an important means to do a good job in public health management. The traditional inspection and appraisal system adopts the total score method to compare the various units. The disadvantage is that the work focus is not prominent and it brings inconvenience to the management work. This article uses the weighted average method to evaluate, in order to overcome this shortcoming. 1 Mathematical model If the evaluation object has m factors, the score for each factor is Si. Because of the different degree of emphasis on each factor, each factor can be given a certain weight according to its degree Pi, and Pi represents the percentage of the ith factor in the judgment. The following formula can be used as a mathematical judgment
