Research on optimization method for hybrid assembly line design

In a dynamical manufacturing environment hybrid assembly line is used widely because of its flexibility and reconfigurability. Hybrid assembly line design problem is more difficult and complex than ordinary simple line design problems. On the basis of modeling the hybrid assembly line design problem and design objectives, an intelligent multiobjective optimization algorithm is proposed. Some essential problems such as the algorithm flowchart, chromosomes encoding, algorithm operators, chromosomes amending, and a kind of Pareto-based multiobjective tackling mechanism are described. A numerical example shows that the proposed method is capable of deal with the constrained multiobjective optimization problem of hybrid assembly line design.
