A hierarchy-invariant Virtual Maintenance Model (hiVMM) is proposed in this paper, in which the structure of the assembly tree of the equipment is kept invariably during the whole process of assembly and disassembly manipulation. A deterministic finite automatic machine of assembly and disassembly process for a component has been defined. The hierarchical(More)
Lots of different kinds of simulators have been developed with low developing efficiency and large effort to make minor changes in practice. We used VRML to describe the objects of submarine cable operation equipments and their behaviors, used user-defined formulas stored in database to control the function of these objects. Therefore, a "Principle(More)
