为了研究多级汽车装配车间的多目标集成排产优化问题,详细讨论了涂装车间的颜色批量约束以及总装车间的空间间隔约束,证明了空间间隔约束是能力约束的充分条件,在此基础上分别给出了无辅助工人和有辅助工人参与情况下的空间间隔约束不等式。以同时优化涂装车间调整费用和总装车间辅助工人费用为目标,建立了一类整数规划数学模型。采用模型非线性约束线性化的方法并结合运用优化软件对模型进行求解。最后通过仿真实例,验证了该方法的可行性和有效性.
In order to study the multi-objective integration scheduling problem of multi-level automobile assembly shop, the color batch constraints of paint shop and the space interval constraints of assembly shop are discussed in detail. It is proved that the space interval constraint is a sufficient condition for capacity constraint. On the basis of this, The space inequality inequalities with no assistant workers and assistant workers are given respectively. In order to optimize the cost of finishing shop and assembly shop assistant worker at the same time, a mathematical model of integer programming is established. The model is solved by using nonlinear constrained linearization method combined with optimization software. Finally, the simulation example shows that the method is feasible and effective.
