摘要
针对缓冲区容量设置不能根据生产需求等因素进行动态调整的问题,通过对约束理论中鼓-缓冲-绳子方法(DrumBuffer-Rope,DBR)进行深入分析,建立了基于系统动力学的DBR模型,以及研究了动态调节系统生产时间缓冲控制机制。对该模型的系统动力学属性进行分析,论证了模型的有效性;并同没有DBR系统缓冲控制机制的生产系统进行对比,验证了该时间缓冲控制机制的优越性;对该时间缓冲控制机制的控制参数进行方差分析,揭示了需求、需求提前期和生产运行等参数对系统运行效率的影响。
Aiming at the problem that the buffer size cannot be adjusted according to demand fluctuations in the production system ,a system dynamic-based approach was proposed to estimate buffer size dynamically. This approach relied on deeply study of the Drum-Buffer-Rope( DBR) mechanism and integrates the system dynamics into the production model. Studied the dynamics of the control mechanism to prove its validity;and then compared it with non-DBR model to prove its superiority;finally studied the effect of policies on shop performance by means of analysis of variance. Extensive numerical investigation reveals the insensitivity of time-buffer policies to key factors related to demand, demand due date and operational characteristics.
