Abstract: Aiming at the problem that capacity factor based Memetic algorithm existed deviation with production practice for solving a light airplane u-shaped assembly line balancing type-Ⅱ problem (UALBP-Ⅱ),the concept of capacity factor was presented,and its definition and value method were given.From the view of production practice,the problem of assembly line balancing was researched.By taking minimum cycle time of assembly line and workload optimization between each workstation as the objective,the multi-objective and multi-constraint mathematical model for a light airplane U-shaped assembly line was established,and the constraint conditions were described in detail.The optimization calculation results of Memetic algorithm based on capacity factor and standard Memetic algorithm in a light aircraft assembly line showed that Memetic algorithm based on capacity factor was more practical and had important practical significance for the production.
