我们研究了一个混合系统的动态行为，其中制造和再制造操作同时发生，以产生相同的可服务的库存订单履行。这样的混合系统，通常在复印机和个人计算机行业中发现，在文献中已经受到相当大的关注。然而，其动态性能和牛鞭效应，下推和拉再制造政策，仍然是未知的。相关分析将允许考虑采用适当的控制策略，因为在基于推的环境中的一些管理规则可能在拉驱动系统中失效，反之亦然。利用非线性控制理论和离散时间仿真，我们开发和线性化的非线性风格化模型，并分析评估牛鞭性能的推和拉控制的混合系统。我们发现产品退货率是拉式控制混杂系统订单方差性能的关键影响因素，从而对推式或拉式策略的选择起着重要的作用。产品需求频率是另一个重要的影响因素，因为订单方差与之呈U型关系，而且产品返回延迟对系统的动力学特性有补充影响。特别地，如果返回率高，则传统的推控混合动力系统可能会受到该因素的显著影响。研究结果强调了联合考虑订货结构和产品需求特征对避免牛鞭效应的重要性。
We study the dynamic behaviour of a hybrid system where manufacturing and remanufacturing operations occur simultaneously to produce the same serviceable inventory for order fulfilment. Such a hybrid system, commonly found in the photocopier and personal computer industries, has received considerable attention in the literature. However, its dynamic performance and resulting bullwhip effect, under push and pull remanufacturing policies, remain unexplored. Relevant analysis would allow considering the adoption of appropriate control strategies, as some of the governing rules in a push-based environment may break down in pull-driven systems, and vice versa. Using nonlinear control theory and discrete-time simulation, we develop and linearise a nonlinear stylised model, and analytically assess bullwhip performance of push- and pull-controlled hybrid systems. We find the product return rate to be the key influencing factor of the order variance performance of pull-controlled hybrid systems, and thus, to play an important role towards push or pull policy selection. Product demand frequency is another important factor, since order variance has a U-shaped relation to it. Moreover, the product return delay shows a supplementary impact on the system's dynamics. In particular, the traditional push-controlled hybrid system may be significantly influenced by this factor if the return rate is high. The results highlight the importance of jointly considering ordering structure and product demand characteristics for bullwhip avoidance.
