@article{Al-Fedaghi_2008, title={SYSTEMS OF THINGS THAT FLOW}, volume={3}, url={https://journals.isss.org/index.php/proceedings52nd/article/view/1001}, abstractNote={Diagrammatical descriptions are used extensively in understanding systems. Typically, systems are expressed in terms of heterogeneous symbols that represent basic characteristics of the system, including elements, connections, flows, communication, etc. This paper introduces a new model to describe flow-based systems. It models “things that flow,” such as information, materials, actions, and money. They are distinguished by flowing in five states: received, processed, created, released, and communicated. The new model is applied to typical systems to contrast them with classical descriptions.
