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、交货期等因素和书目供全率、书目重复比率、按期交货率等多个评价指标。应用改进密切值法进行综合评价,首先由各个评价指标的极端情况组成“虚拟”的最优和最劣供应商方案,其次求出各个图书供应商与最优、最劣供应商的距离,并进而求得反映与最优和最劣供应商距离的综合参数——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。
The advantages and disadvantages of the book supplier depends on the supplier’s book supply capacity, service quality, delivery time and other factors and the bibliography for the full rate, bibliographic repetition rate, schedule delivery rate and other evaluation indicators. The improved value of close method is used to make a comprehensive evaluation. First, the best and worst supplier solutions of “virtual ” are formed by the extremes of each evaluation index, and secondly, the distance between each book supplier and the best and worst suppliers , And then get a comprehensive parameter reflecting the distance from the best and the worst supplier - the close value. The calculation example shows that it is practicable to use the improved close value method to rank the results reliably and to evaluate and sort the comprehensive selection of book suppliers.
