Representation of disassembly processes in order to allow time evaluation of their performances

This paper introduces the tools used to represent disassembly processes. These tools have to allow designers representing processes at each design stages and have to allow time evaluation of process performances. Three levels of precision in the description of disassembly processes are defined: level 0 which represents the process at product level, level 1 which is an operating mode level, and level 2 which is a system level. For each level, a representation tool is given. The more precise level allows process simulation and the evaluation of performances.
