CRIS: The need

         A separate organisation was considered better suited to take up all computer activities on IR mainly for the following reasons :

• to avoid duplication of efforts by individual Railways.
• to ensure standardisation of computer hardware and software on the Railways.
• to undertake design and development of major applications on Railways requiring higher levels of expertise, faster decision making and system wide applicability.
• to insulate the organisation from day to day working of the Railways so that its objectives are not lost sight of.
• need for a combined effort of Railways and Computer Specialists, considered best suited for the development of the computer applications on Railways.
• need for development of expertise in highly specialised fields like Operation Research, Simulation, Expert System, CAD/CAM, Process Control etc.
• need for greater flexibility to keep pace with the fast changing technology.

The following  are the main projects  that are handled  by CRIS  :

• Passenger Reservation System (PRS)
