Maintenance data and information processing is an essential and important problem in collaborative virtual maintenance of complex equipments. Significant research has been done in this paper to provide an efficient approach to performing the data and information processing of collaborative virtual disassembly and assembly operations. Assembly oriented mathematical model of collaborative virtual maintenance operation process is presented with the behavior representation and information description of each component in an assembly based on single object oriented modeling of collaborative maintenance operation as well as assembly oriented modeling of disassembly and assembly operations. Assembly oriented control algorithms of disassembly and assembly operations in collaborative virtual maintenance process are also designed to perform the required data and information processing. With the object information template based on Extensible Markup Language, proposed mathematical models and control algorithms are utilized in a technical experiment system with high reliability and efficiency. Experimental implementation has been done to find appropriate and efficient mathematical models and control algorithms can support effectively the data and information processing of collaborative virtual disassembly and assembly operations of complex products. Methodologies developed in this paper extend the previous work on mathematical modeling and information processing complexity, and improve the reliability and efficiency of required data and information processing in collaborative virtual maintenance process.
