Polyacrylonitrile precursor fiber as the as-spun fiber of carbon fiber plays a vital role in carbon fiber performances. In order to optimize the production process and the fiber performances of polyacrylonitrile precursor fiber, a production parameters optimization approach is proposed to find the relationship between the initial input and the final output of this fiber production and help to determine the production parameters according to the fiber performances required. Because fiber production is a complex industry process with a lot of parameters working together and them all have effect on the final performances, so this optimization is a multi-objective optimization which is based on particle swarm optimization formulas and production data. This approach can maintain the diversity of solutions, improve the accuracy of production parameters determining and provide a optimization of polyacrylonitrile precursor fiber.
