英文摘要：

To solve the collaborative manufacturing task assignment problem,a multi-objective optimization model is devel-oped to minimize the task time,cost and maximize the machining quality.In order to simplify the problem,the multiple objec-tives problem is converted into the single objective problem using the classical weighting algorithm.FAHP is adopted to es-tablish a fuzzy analytical hierarchy model for the collaborative manufacturing task assignment problem to satisfy different us-ers’request,and then the weights of each objective are obtained.Based on the model,a modified genetic simulated annealingalgorithm is designed to solve the model.Finally,an example is given to prove the model and algorithm to be efficient
