Abstract: The information metrology discipline group contains several related disciplines, which are increasingly showing a trend of integration. It is necessary to critically think about the basic problems faced by integration and to clarify its research ideas.Through the analysis and sorting of the current status and problems of the integration of the information metrology discipline group,the basic problems of the infrastructure and structure construction faced by the integration of the information metrology discipline group are put forward.In the meanwhile, using the knowledge system of the tree structure of analogy method,the genetic investigation method of the discipline system is also proposed.Based on the “discipline-object-researcher” relationship and “information basic cycle process” of the information metrology discipline group, the overall courses foundation construction can be carried out, and the establishment of “content-structure-form” and “uniformity” Integrated information metrology discipline system will be under further discussion.
