This paper considers the first-line operators of the manufacturing plant, and the historical process data of operators in their work stations is studied. Based on the method of the angle cosine empowering, the dynamic weights of the quality index and time index are determined, and the fuzzy matrix with optimal mem- bership degree is created to calculate the competence index of the operators that can reflect the dynamic tend- ency of their competence. Then according to the competence index, the number of tasks of the stations is computed, and the optimization configuration model of the operators is established. The hybrid particle swarm optimization（PSO） algorithm is used to solve the model, and the specific solving process is given. The validity and practicality of the proposed model are verified by a case.
