概述了外包理论核心思想及信息技术外包在中国的发展现状和趋势,假设IT(informationtechnology)服务使用方追求成本最小化与顾客服务水平的最大化而IT服务提供方则追求信息服务质量的最大化与成本的最小化,同时考虑到双方分阶段协商互动的特点,使用二层模糊多目标模型进行了分析研究.作为上层决策者的IT服务需求方与作为下层决策者的IT服务使用方首先针对所面对的问题共同提出与问题有关的各种约束和目标函数;然后,双方分别求解自身问题的最优解,若双方解不相符合,双方再根据前面所求解对目标函数值与特定变量值设定可容忍变化范围再对新问题求解,直到双方接受妥协解,文章最后给出了具体算例. It summarizes the core idea of ​​outsourcing theory and the status quo and trend of information technology outsourcing development in China. Suppose IT (informationtechnology) service providers pursue cost minimization and customer service maximization while IT service providers pursue information service quality maximization And minimization of costs, taking into account the two phases of the negotiation and interaction characteristics, the use of two-tier fuzzy multi-objective model for analysis and research.As the upper decision-makers of IT service demand side and as the lower decision-makers of IT service consumers first targeted The problems they face jointly put forward various constraints and objective functions related to the problem; then, the two parties respectively solve the optimal solution of their own problems, and if both solutions are not consistent, the two sides reconsider the objective function value and the specific variable The value set can be tolerated within the scope of change and then solve the new problem, until both parties accept the compromise solution, the article gives the final examples.
