本文在借鉴CMMI技术上,构建了信息服务成熟度模型。通过引入证据理论方法评价信息服务提供商的成熟度,其目的在于解决现有评价方法存在的判断矩阵一致性难以满足、以及专家对指标属性值和隶属度值难以确定等问题。经算例研究结果证明:本文提出的评价模型能够准确可靠的评价信息服务成熟度,亦可作为用户评价或选择信息服务提供商的重要工具。
In this paper, drawing on CMMI technology, build a model of information service maturity. The purpose of evaluating the maturity of information service providers through the introduction of evidence theory is to solve the problems that the consistency of judgment matrix existing in the existing evaluation methods is difficult to meet and the experts are hard to determine the value of attribute and the membership value. The results of a case study prove that the evaluation model proposed in this paper can accurately and reliably evaluate the maturity of information services and can be used as an important tool for users to evaluate or select information service providers.
