Based on the rational cost function and cyclical checking of PUSH and PULL models, it simulates and analyzes the average costs of those systems in different leadtimes, shows the influences on general system costs imposed of different leadtimes.

• 针对周期性检查PUSH和PULL策略模型,通过建立合理的成本函数,应用仿真手段分析了不同提前期下的混合制造/再制造系统平均成本,并比较了不同制造提前期与再制造提前期对系统总成本的影响。
