Research and Application of Requirement Acquisition Methods for Railway Information System Standardization
To meet the needs of CR regional group in standardizing information systems across various business areas,this study proposes a GOB-based requirement acquisition method.It clarifies the requirements for the standardization of information systems and assists in the implementation of the standardization work.The GOB-based requirement acquisition method adopts a three-dimensional integrated approach focused on"planning guidance-organizational functions-business processes"to obtain the"five-dimensional integrated"MBDTO requirements,which include management requirements,business requirements,data requirements,technical requirements,and O&M requirements.Taking China Railway Jinan Bureau Group Co.,Ltd.,as an example,this paper analyzes its current system status and elaborates on the practical application process of the GOB requirement acquisition method in the integrated office domain.This can provide valuable insights and experiences for other CR regional groups in their information system standardization efforts.
