Abstract：In view of the fact that product disassembly efficiency is not taken into consideration in the traditional method based on
experts’ experience, a new quantitative evaluation method of product disassembly is herein presented based on parts failure rate and
its disassembly time. Product information model with respect to its disassembly constraint graph is established on the basis of graph
theory thought and object-oriented technology. Through developing the procedures of product disassembly sequence generation and
optimization, parts disassembly process is simulated and a method of determining the basic disassembly time of product parts is
proposed on the basis of modular arrangement of predetermined time standard (MODAPTS). By introducing part failure rate weight,
basic disassembly time is converted to relative disassembly time and a calculation model of product disassembly efficiency is
established on the basis of parts failure rate and its disassembly time so that the quantitative analysis and evaluation of product
disassembly is implemented. The calculation method and its evaluation steps of product disassembly efficiency are demonstrated by
combining with one example. Furthermore, the example shows that this quantitative evaluation method is reasonable, feasible, and
able to optimize product disassembly design, thus having good engineering application value.
