针对静态设置的缓冲区容量不能根据生产系统波动程度进行调整的问题，提出一种动态设置缓冲区容量的方法。首先分析影响缓冲区容量设置的3个因素，采用G／G／1排队模型衡量瓶颈前工序生产自然波动、瓶颈前工序数量和瓶颈工序随机波动对缓冲区容量设置的影响，并考虑避免机器故障和机器维修导致的瓶颈“饥饿”，求解机器故障因素和机器维修因素所需要的最小缓冲区容量。在此基础上，提出一种基于系统仿真的动态调节缓冲区容量的方法。最后通过案例分析，验证了所提方法的有效性和实用性。

Aiming at the problem that static buffer size cannot be adjusted according to fluctuations in the production system , an approach is proposed to estimate buffer size dynamically .The three factors which have an impact on constraint buffer size are analyzed and the buffer size to offset fluctuation caused by fluc -tuation of process before the constraint , number of process before the constraint and fluctuation of the con-straint via G/G/1 model estimated .Also estimated is the minimum buffer size to avoid bottleneck starva-tion caused by machine failure and machine maintenance .On this basis , a method which can adjust buffer size dynamically based on simulation is proposed .A production example is given , which proves the validity and usability of the proposed method .
