Abstract
Two alternative methods of knowledge representation, Petri net and event bush, have been applied to represent the same environments of alternative directed changes. The chapter examines the interrelation between the two methods and considers the ways of their mutual optimization and co-application. It discusses the balance between conceptual thoroughness and formal transparency from one side and readability, representation power, and common-sense clarity from the other. The interrelation and interplay of these two methods may bring fruitful revelations about how to treat dynamic knowledge, what strategy to choose to represent scenarios depending on the task in mind. This is seen as an important contribution to a new field of research, representation of dynamic knowledge, which may have wide application in a variety of fields, from history to technical design.
