This paper outlines an object/agent based system model for the Computer Integrated Process Operation System (CIPOS). Most previous studies have focused on the Computer Aided Process Operation system (CAPO), while they are standalone and not good at communication with each other. The system model proposed in this work can solve some key integrated problems in CIPOS, which are problem integration, task integration, tools integration and personnel involvement. An instantiated system, TE_CIPOS, is implemented to give further explanation and verification of the proposed object/agent based system model and its integrating environment.
