我们研究了一个通用的、简单的通信过程模型。在该模型中，网络（特别是组织）中的代理按照简单的规则交换信息包，这些规则考虑了代理处理数据包的有限能力以及与开放通信通道存在相关的成本。由于能力的限制，网络在一定条件下会崩溃。我们的重点是当崩溃发生的分层网络，也对结构的平坦度或陡峭度的影响。我们发现对层级的需求与昂贵连接的存在有关。(C) 2001 Elsevier Science B.V.版权所有
We study a general and simple model for communication processes. In the model, agents in a network (in particular, an organization) interchange information packets following simple rules that take into account the limited capability of the agents to deal with packets and the cost associated with the existence of open communication channels. Due to the limitation in the capability, the network collapses under certain conditions. We focus on when the collapse occurs for hierarchical networks and also on the influence of the flatness or steepness of the structure. We find that the need for hierarchy is related to the existence of costly connections. (C) 2001 Elsevier Science B.V. All rights reserved.
