带区间信息的高校图书馆服务质量群决策评价模型

A Group Decision-Making Evaluation Model for University Library Service Quality with Interval Information

高校图书馆的服务质量评价一直是备受关注的问题。现有的评价方法缺乏对不同类群体用户需求的关注。针对这个问题,文章建立了一种基于不同类型群体决策的高校图书馆服务质量综合评价模型。首先根据现有投影测度的缺陷,给出了一个广义标准化投影测度公式。该公式能综合测度两个区间向量的接近程度,并应用于测度带有区间信息的两个评价矩阵的接近程度;其次,将新提出的投影测度公式应用于改进的TOPSIS方法中,建立了一种含实数和区间数混合信息的群决策模型;最后,将该模型应用于广东省某4所高校图书馆服务质量的评价中。实验分析表明,该模型具有较好的鲁棒性和稳定性。

The evaluation of service quality in university libraries has long been a subject of significant interest.Existing evaluation methods often overlook the diverse needs of various user groups.To address this concern,this paper presents a comprehensive evaluation model for university library service quality based on decision-making among different types of user groups.Initially,a generalized standardization projection metric formula is introduced to address the limitations of current projection measures.This formula provides a comprehensive measure of the similarity between two interval vectors and is applied to assess the proximity of evaluation matrices containing interval information.Subsequently,the newly derived projection metric formula is integrated into an enhanced TOPSIS(Technique for Order of Preference by Similarity to Ideal Solution)method,resulting in a group decision-making model that combines real and interval data.Finally,this model is applied to the evaluation of library service quality at four universities in Guangdong Province.Experimental analysis demonstrates that the proposed model exhibits robustness and stability.
