Hierarchy Analysis Method for Management Information Systems

摘要

There are many kinds of management information systems (MISs) whether in industries or in enterprises. In China, most of MISs were put into application at different time and with different demands. With the broader application of MISs, it's becoming greater important to integrate them and realize information sharing. Hierarchy analysis method gives out a general structure for the complicated integration of MISs. There are two steps for this method, (l)measure the information communication relations among MISs,(2) divide MISs into multi grade structure. For China railway industry, there are 13 kinds of big MISs, take them as an example to illustrate how to apply this method. Based on hierarchy analysis, MISs with strong connections have priority while integrating MISs. The higher the grade of MIS, the greater overall layout design priority should be given, for more information from other MISs finally reach it.
