AI summary

A product disassembling method and non-transitory computer readable media thereof are provided. According to the components of the product and the disassembling attributes of the components, the disassembling sequence that minimizes the total disassembling time can be planned. The method includes the following steps: an initial disassembling sequence solution is randomly generated. The disassembling sequence solution is updated by using an update mechanism. The disassembling time of the update disassembling sequence solution is calculated by using a fitness function. The best fitness value is obtained after the continuously updating, so as to determine whether to update or maintain the initial disassembling sequence solution. The corresponding disassembling sequence is considered as the best planning result.
