Standard description model for process information in networked environment

Difficulty in the process information sharing outside enterprises in networked manufacturing environment was analyzed. And the Standard Description Model for Process Information (SDM-PI) was proposed. SDM-PI consisted of two elements: Information Content (IC) and Handling Method (HM). IC was responsible for recording the process information, and HM was responsible for handling the information recorded in IC. By applying various handling methods in HM, SDM-PI acquire, check and convert information displayed in SDM-PI's form. Finally, an application case was analyzed.
