System Entity Structure Basics

Abstract

In this chapter, you will see how the System Entity Structure (SES ) can help you construct models for Systems of Systems. In fact, we will use the SES to better understand the process for constructing such models. Modeling and Simulation (M&S) refers to a set of activities that are undertaken for a variety of reasons. We get a sense of the activities involved in M&S from a bird’s eye perspective before we dive down into DEVS-based tools for simulation model construction, the focus of this book. We formulate some of the basic activities in Modeling and Simulation as a process or sequence of steps that can be represented with a System Entity Structure. Besides conveying some familiarity with M&S activities, we use the example to discuss two unique features of the SES, decomposition and coupling.
