我们提出了一个自组织的，分散的控制方法，在网络中的物质流。这个概念适用于网络中的冲突流之间的时间共享机制，节点是必需的，这些本地交换机在系统范围内的协调可以提高性能。我们表明，在一定的假设下，节点的控制可以映射到网络的相位振荡器。通过同步这些振荡器，实现了所需的全局协调。最后以路网交通信号控制为例说明了该方法。所提出的概念是灵活的，自适应的，强大的和分散的。它可以转移到其他排队网络，如生产系统。我们的控制方法利用在各种生物系统中发现的简单同步原理，以便从局部相互作用中获得集体行为。
We present a self-organising, decentralised control method for material flows in networks. The concept applies to networks where time sharing mechanisms between conflicting flows in nodes are required and where a coordination of these local switches on a system-wide level can improve the performance. We show that, under certain assumptions, the control of nodes can be mapped to a network of phase-oscillators. By synchronising these oscillators, the desired global coordination is achieved. We illustrate the method in the example of traffic signal control for road networks. The proposed concept is flexible, adaptive, robust and decentralised. It can be transferred to other queuing networks such as production systems. Our control approach makes use of simple synchronisation principles found in various biological systems in order to obtain collective behaviour from local interactions.
