中文简介:
通过考虑到未来的到达,可以预测排队过程的相关动态。如果从一个队列到另一个队列的传输与传输延迟有关,正如交通或生产网络的典型情况一样,未来到达一个队列的时间跨度是已知的,因此,可以用于对相应流的预期控制。通过在“开”和“关”之间切换其流出来控制队列。Milar到绿色和红色交通灯,在这里切换到“开”需要非零设置时间。由于连续和离散状态变量的存在,排队过程被描述为一个混合动力系统。从这个公式中,我们得出一个非常重要的观察结果:清除队列所需的绿灯时间。这个数量允许不延迟地检测为排服务的切换时间点,即以“绿波”方式。此外,我们根据额外的等待时间来量化延迟服务期开始或终止的成本。我们的研究结果可作为战略控制决策的基础。
课程简介: The relevant dynamics of a queueing process can be anticipated by taking future arrivals into account. If the transport from one queue to another is associated with transportation delays, as it is typical for traffic or productions networks, future arrivals to a queue are known over some time horizon and, thus, can be used for an anticipative control of the corresponding flows.A queue is controlled by switching its outflow between 'on' and 'off' similar to green and red traffic lights, where switching to 'on' requires a non-zero setup time. Due to the presence of both, continuous and discrete state variables, the queueing process is described as a hybrid dynamical system. From this formulation, we derive one observable of fundamental importance: the green time required to clear the queue. This quantity allows to detect switching time points for serving platoons without delay, i.e., in a 'green' wave manner. Moreover, we quantify the cost of delaying the start of a service period or its termination in terms of additional waiting time. Our findings may serve as a basis for strategic control decisions.
