We have developed life cycle management system for accelerator equipment. It manages whole life cycle of equipment used in accelerators from production to scrapping. The key component of the system is labels two dimensional bar code (QR-code) sticked on equipment at the production time. A dedicated device reads ten digit serial number on the label at every event on the equipment i.e. production, delivery, temporary stock, installation, repair, re-installation and scrapping. Labels sticked on wall or floor of the building manages the location of equipment. A relational database management system (RDBMS) stores data. Users can access data from the web interface. Web based GIS (Geographic Information System) provides interactive map to display location of equipment. Documentations on equipment are also manged by the RDBMS. We present the design, implementation and operation of the system.
