ERP(enterprise resource planning,企业资源计划)系统的分步云化是降低ERP云化风险的有效手段,而选择出ERP中优先云化的功能是实现ERP系统分步云化的前提.首先基于信息强度理论,从传统ERP使用角度提出了测量信息强度的指标;然后基于二分网络方法建立用户-功能网络模型,定义了企业业务域的信息绝对强度和信息关联强度,提出了基于信息强度的ERP分步云化的选择方法;最后利用一家大型船舶制造企业ERP日志数据进行了实例分析,验证了该方法的有效性.
The step by step cloud system of ERP (enterprise resource planning) is an effective way to reduce the risk of ERP cloud, and the function of selecting the priority cloud in ERP is the premise of realizing the cloud system step by step.Firstly, based on the information Strength theory, the index of measuring information intensity is put forward from the perspective of traditional ERP. Secondly, based on the dichotomy network method, a user-function network model is established to define the absolute information strength and the information correlation strength of the enterprise business domain. Finally, the paper uses an example of ERP log data of a large shipbuilding enterprise to verify the effectiveness of the method.
