Abstract：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 .
