Composability and Component-Based Discrete Event Simulation
MetadataShow full item record
This work presents a framework and a Graphical User Interface, Viskit, for the creation and analysis of component- based Discrete Event Simulation models. Two primary elements of the tool are discussed. In component design mode, a new component is created by drawing the Event Graph and filling in parameters, so that the simulation modeler need not be a sophisticated programmer. In component construction (assembly) mode, components are hooked together to create a model. In analysis mode, the models are exercised and run according to the desired experimental design.We start with basic terminology and concepts of modeling, and decompose the art of modeling as a process. This overview of the process helps clarify when we should or should not use simulation models. We discuss some common missteps made by many inexperienced modelers, and propose a concrete approach for avoiding those mistakes. After a quick review random number and random variate generation, we view the simulation model as a black-box which transforms inputs to outputs. This helps frame the need for designed experiments to help us gain better understanding of the system being modeled.
