To decide the best AGV quantity configuration,a mathematic model was set up using process,AGV path,dispatch rule as constraint,and making sure the outputs of workshop be largest.Due to the complexity of the problem,an optimal method based on simulation optimization was proposed,using simulation model to simulate the running of AGVs and the algorithm GA to determine the quantity of AGVs.At last,validity and feasibility of the method were proved by a case study of air-condition assembly workshop.

以生产线产能最大化为目标，以生产工艺、AGV路径、调度规则等为约束条件，建立了以AGV的数量为决策变量的数学模型来描述AGV的数量配置问题。针对该问题的复杂性，提出了基于仿真的优化方法。该方法利用仿真模型模拟AGV运行状态，并通过遗传算法确定AGV的配置数量，有效地提高了模拟的精确度与优化的速度。最后通过空调装配车间实例验证了该方法的有效性和可行性。
