Disassembly operations of used machines are very important processes for recycling and reuse of various materials and parts. This paper treats the fundamental concepts of disassembly and the simulation method for planning of disassembly operation using Timed Petri Nets (TPN). Some disassembly operation processes, arranged in parallel, are expressed by a TPN model considering the each function of system. Using this simulation method, the efficient schedule of disassembly process can be obtained analytically. It is shown also that the systems with some AGVs and/or buffers can be treated by this method. This simulation method has following advantages: (1) It is easy to understand the whole process of disassembly systems because the functions of systems are visually shown by the flow diagrams. (2) Mathematical treatment may be possible for time schedule analysis of disassembly processes. These advantages suggest that the proposed method is very useful for analyzing the efficiency and the design of the disassembly systems.
