Abstract：In order to make the best of experts’experience and knowledge from assembly process in face of assembly market and to solve assembly coordination sequence optimization question, an assembly coordination sequence optimization based on membership function method is presented. 7 rank evaluation standards are set to mark by the experts that compare random of each two assembly coordination sequences. Calculate total score and precedence selection ratio to form precedence matrix of relation. And finally, membership degree of each assembly coordination sequence is calculated by average arithmetic, and the biggest of which is the best assembly coordination sequence. And the method is applied to a certain aircraft wing as an experiment.
