摘　　要：针对目前市场上电子资源提供商种类繁多、图书馆经费有限的现状,提出一种面向电子资源采购的决策支持模型。首先根据图书馆自身情况建立电子资源评价体系,为每个数据库确定评分;然后,以各个数据库的评分、价格,以及图书馆的总预算作为输入,在预算范围内通过动态规划技术寻找使资源结构最优化的采购方案,从而为图书馆的采购人员提供决策参考;最后,以西南大学图书馆为实例,验证模型输出结果的有效性。利用德尔菲法确定该图书馆的资源评价体系,并编码实现决策支持模型系统,以计算得出推荐方案。综合对比人工决策结果,证明动态规划决策支持模型可以获得更优的资源配置。This paper proposes a solution model for e-resources procurement in view of the current situation of numerous e-resources providers and limited library funds in the market.Firstly,the e-resources evaluation system is established according to the situation of the library,and the score is determined for each database.Then,with the score,price of each database,total budget of the library as input,dynamic programming is used to find the procurement scheme to optimize the resource structure within the budget scope,so as to provide reference for the procurement staff of the library to make decisions.At last,taking Southwest University Library as an example,the validity of the model output results is verified.The Delphi method is used to determine the library’s resource evaluation system,and the decision model system is coded to calculate the recommended scheme.It is proved that the dynamic programming decision model can obtain better resource allocation and verify the validity of the output results of the model.
