Generic Structures, Systems Archetypes, and Theories

Abstract

SFD—stock and flow diagram—is the semasiographic language for describing dynamics of systems. But what are SFD “sentences” called that consist of the eight terms or symbols—stock, flow, two types of causal links, two types of causal loops, delay, and sources and sinks—and what is their purpose in managing complexity? This question is the topic of this chapter.
