组织越来越多地面临着构建复杂系统的挑战，这些系统必须在系统环境的系统中运行。虽然网络科学提供了对产品和系统架构的有用的清晰见解，但我们寻求将这些方法扩展到评估企业系统架构。在这里，我们探索应用图论方法来分析两个现实世界的企业架构(军事通信系统和搜救系统)，并评估不同架构组件的相对重要性。对于这两种体系结构，组件重要性的不同拓扑度量将不同的网络顶点标识为重要。由此，我们确定了系统架构师在使用图论方法评估体系结构时需要认识到的几个重要挑战；找到异类体系结构元素的适当抽象，以及区分网络结构属性和系统功能属性。这些挑战被总结为利用网络科学概念进行企业架构评估的五个指导原则。
Organizations are increasingly faced with the challenge of architecting complex systems that must operate within a System of Systems context. While network science has offered usefully clear insights into product and system architectures, we seek to extend these approaches to evaluate enterprise system architectures. Here, we explore the application of graph‐theoretic methods to the analysis of two real‐world enterprise architectures (a military communications system and a search and rescue system) and to assess the relative importance of different architecture components. For both architectures, different topological measures of component significance identify differing network vertices as important. From this, we identify several significant challenges a system architect needs to be cognisant of when employing graph‐theoretic approaches to evaluate architectures; finding suitable abstractions of heterogeneous architectural elements and distinguishing between network‐structural properties and system‐functional properties. These challenges are summarized as five guiding principles for utilizing network science concepts for enterprise architecture evaluation.
