企业信息系统云化迁移的评估方法

A Method for Evaluating Cloud Migration of Enterprise Information Systems

文章首先建立了企业信息系统云化迁移评估的指标集,对指标值采用了三角模糊数处理方法并经规范化处理后得到决策矩阵;其次将决策矩阵的正、负理想点作为参考点,依据前景价值函数计算正、负前景矩阵,以灰色关联法获得各指标权重,计算各备选信息系统云化迁移的综合前景值,得到企业对备选信息系统的迁移意愿及相对次序。最后采用该评估方法对制造业和服务业的大中小型企业进行了实例分析。

This paper proposed a method to assess cloud migration of enterprise information systems based on the prospect theory. First it set the evaluation index, the value of which are transformed and processed by triangular fuzzy numbers, and then formalized into the decision matrix. Then it used the positive and negative ideal solutions as reference schemes to calculate the positive and negative prospect value matrix with prospect value function. Also it used grey correlation method to get the weight vector to calculate the comprehension prospect value of each candidate information system. With the result, it shows the intent of an enterprise to migrate all candidate information systems to the cloud and their relative order. Finally, the method is validated by an empirical analysis on enterprises in different scale from manufacturing industry and service industry.
