| 摘 要： | 如何选择信誉好、服务优的图书供应商已经成为图书馆图书采购必须要解决的首要问题。本文将改进密切值法应用于图书供应商选择的综合评价研究。图书供应商的优劣选择主要取决于供应商的图书供应能力、服务质量、价格、信誉、交货期等因素，涉及书目供全率、书目重复比率、按期交货率、到书率等多个评价指标。首先由各图书供应商选择的各个评价指标的极端情况组成“虚拟”的最好和最差供应商方案，其次求出各个图书供应商与最好、最差供应商方案的距离，再引进可综合反映与最好和最差供应商方案距离两者水平的综合参数—密切值。计算实例表明，用改进密切值法的排序结果可靠，用于图书供应商的综合选择评价与排序是切实可行的，并且密切值法计算过程简单，很容易实现计算机化。

| Abstract: | Osculating method was an optimization approach for multi-objective decision, and it is a trial to comprehend assessment of book supplier quality using osculating method. Ten assessment indexes were used to assess the book supplier quality. The best and worst supplier were composed of the maximum and minimum values of assessment indexes. A comprehensive parameter, namely osculating value, taking the distances between the evaluated book supplier and the best or worst supplier into consideration simultaneously was introduced and used to evaluate and order the book suppliers. The case study showed that the osculating method presented the reliable results in disagreement with the results of gray relation theory. The osculating method was thus suitable for the comprehensive assessment of book suppliers. The calculation of the osculating method was simple and carried conveniently out on computer. |
