竞争的加剧以及加强自身核心竞争力的考虑,许多公司尤其是中小型公司都纷纷将非核心信息系统业务外包,而信息服务提供商的选择直接影响外包的成功与否。首先根据文献结果建立信息服务提供商(Information service provider,ISP)的评价指标体系,创新性地考虑处在外包不同生命周期的信息服务使用方对信息服务提供方的评价属性侧重点有所不同,把指标属性分为关键属性,重要属性和基本属性,并用模糊语言变量进行刻画,分不同等级的模糊语言变量表示不同确定性程度的属性,然后,运用模糊多属性决策方法对信息服务提供商进行动态选择,最后给出具体算例。
Increasing competition and strengthening its own core competitiveness, many companies, especially small and medium-sized companies have outsourced the business of non-core information systems, and the choice of information service providers has a direct impact on the success of outsourcing. First of all, based on the literature results, we establish the evaluation index system of information service provider (ISP), and consider innovatively that the information service providers who are outsourcing different life cycles have different emphasis on the evaluation attributes of information service providers. The index attributes are divided into key attributes, important attributes and basic attributes, and are characterized by fuzzy linguistic variables. Different levels of fuzzy linguistic variables represent attributes with different certainty degree. Then, fuzzy multi-attribute decision-making method is applied to information service providers Dynamic selection, the final examples given.
