In the designing and modeling of CPSs, the information acquisition and processing processes are often application dependent and process oriented. Those information management frameworks are simple and effective for small scale systems. However, many functions developed are not reusable or cannot be directly re-used, when a large number of details and relations need to be added. Aiming at designing a flexible and scalable system with “plug-and-play” components, a preliminary information acquisition and processing framework for CPSs is proposed in this paper based on the object oriented design (OOD) method. The concept of informational hierarchy within CPSs is identified first. Then it is further elaborated as instantaneous information, dynamic information and context information. Using these three types of information, together with the physical properties of a component in CPSs, the concept of hybrid object is proposed as the basic component of the proposed framework. By defining the inherent and update operation of hybrid objects, the proposed information acquisition and processing framework is formed with hierarchical hybrid objects. To verify the effectiveness and the efficiency of the proposed framework, a case study on designing and modeling a gas metal arc welding (GMAW) based rapid manufacturing system is presented. Limitations of the proposed framework and future research directions are discussed as well.
