动态生产线平衡（DLB）是指在装配线运行过程中，连续工位之间装配任务（共享任务）的动态转移。在传统的装配线中，工作共享是不允许的。因此，循环时间由在最大负载站中执行的工作量确定。与传统生产线相比，DLB方法能够实现更短的周期时间和更高的吞吐率。在DLB方法的实现中，必须确定以下内容：（1）共享任务的身份，以及（2）操作任务分配规则。在某些情况下，还需要关于每个共享任务将在工作站中执行的循环百分比的数据。我们首先分析的情况下，其中一个初始的任务分配给车站（线平衡的解决方案）和身份的共享任务是已知的，并给出。的平衡性（DLB的能力，以实现一个完美的平衡线在稳定状态下的等效性能）的条件开发，以及制定最小化的周期时间。其次，基于瓶颈段的新概念，考虑了共享成本，给出了最小化共享时间和共享成本的方法。操作方面也得到了解决，同时检查几个状态相关和状态无关的操作规则的周期时间和系统的工作过程中的任务分配的效果。
Dynamic line balancing (DLB) deals with dynamic shifting of assembly tasks (shared tasks) between consecutive stations during the operation of the assembly line. In traditional assembly lines, work-sharing is not allowed. Consequently, the cycle time is determined by the amount of work performed in the most loaded station. The DLB approach enables achieving a shorter cycle time and a higher throughput rate, as compared to the traditional lines. In the implementation of the DLB approach the following has to be determined: (1) the identity of the shared tasks, and (2) the operational task allocation rule. In some cases, the data regarding the percentage of cycles each shared task will be performed in a station is also required. We first analyse a case in which an initial task assignment to stations (line balance solution) and the identity of the shared tasks is known and given. Conditions for the balanceability (the ability of the DLB to achieve an equivalent performance to a perfect balanced line in the steady state) are developed, as well as the formulation for minimizing the cycle time. Next, the sharing costs are considered and approaches for minimizing the shared time and sharing cost are presented, based on the new concept of bottleneck segment. The operational aspect is also addressed, while examining the effect of several state-dependent and state-independent operating rules for task allocation on the cycle time and the system work in process.
