So you have built and validated a simulation model - how are you going to gain insight about the associated real system in order to make decisions? This introductory tutorial gives an overview of experiment design techniques for planning a series of simulation runs. These techniques make efficient use of simulation runs to uncover the impact of system design parameters on simulation output performance...
A simulation project is much more than building a model. And the skills required go well beyond knowing a particular simulation tool. This paper discusses some important steps to enable project success and some cautions and tips to help avoid common traps.
In this introductory tutorial we discuss the problem of pricing financial derivatives, the key application of Monte Carlo in finance. We review the mathematics that uses no-arbitrage principle to price derivatives and expresses derivatives price as an expectation under the equivalent martingale measure. In the presentation at the conference we will also elaborate on the use of Monte Carlo methods...
Petri Nets provide a graphical notation for modeling systems and performing analysis. Colored Petri Nets (CPNs) combine the strengths of ordinary Petri Nets with a high level programming language, making them more suitable for modeling large systems. A CPN model is an executable representation of a system that can be analyzed through simulation. CPN models are built using CPN Tools, a graphical software...
This tutorial introduces concepts for modeling small unit combat as complex adaptive systems (CAS). It begins with a “human-centric” view of the individual combatant and small unit operations,which incorporates the concept of the individual as an integrated weapon system, the Warrior System. It addresses representation of situation awareness/situation understanding (SA/SU), and “soft” factors - morale,...
This tutorial demonstrates the use of agent-based simulation (ABS) in modeling emergent behaviors. We first introduce key concepts of ABS by using two simple examples: the Game of Life and the Boids models. We illustrate agent-based modeling issues and simulation of emergent behaviors by using examples in social networks, auction-type markets, emergency evacuation, crowd behavior under normal situations,...
This paper provides simulation practitioners and consumers with a grounding in how discrete-event simulation software works. Topics include discrete-event systems; entities, resources, control elements and operations; simulation runs; entity states; entity lists; and entity-list management. The implementation of these generic ideas in AutoMod, SLX, and ExtendSim is described. The paper concludes with...
In this paper we discuss verification and validation of simulation models. Four different approaches to deciding model validity are described; two different paradigms that relate verification and validation to the model development process are presented; various validation techniques are defined; conceptual model validity, model verification, operational validity, and data validity are discussed;...
The initial transient is an unavoidable issue when estimating parameters of steady-state distributions. We discuss contexts and factors that affect how the initial transient is handled, provide a bibliography (from the system simulation literature), discuss criteria for evaluating initial-transient algorithms, arguing for focusing on the mean squared error (mse). We discuss the MSER statistic, showing...
Advanced design support solutions such as 3D simulations have enabled improved management of design information for years. The challenge, however, is that acquiring these type of design support solutions does not necessarily create a visible business value for the company in a short run. Moreover, the organization surrounding the simulation solution should support its use by providing the conditions...
Simulation models are built using one or more “world views” that provide the underlying framework for defining the system of interest. This tutorial presents an overview and brief history of the alternative modeling world views for discrete event simulation. In specific this tutorial discusses the event, process, and object world views, and highlights the differences and relationships between these...
Today, due to exciting developments in advanced computing techniques and technologies, many scientists can now make use of dedicated high speed networks and high performance computing. This so-called `e-Science' in enabling scientist across many fields to work together in global virtual research communities. What do these advancements mean for modeling and simulation? This advanced tutorial instigates...
This paper proposes an open-source algorithm for simulation optimization. The intent is to permit many who use a variety of simulation software codes to be able to apply the proposed methods using an MS Excel-Visual Basic interface. First, we review selected literature on simulation optimization and its usefulness. Then, we briefly discuss methods that are commonly used for simulation optimization...
This paper presents a new tool for the teaching professional and students of Project Management-a tool that can easily integrate traditional teaching based on any course or textbook available in the market. The Project Team Builder software tool combines an interactive, dynamic case study and a simple yet effective Project Management System. The Project Team Builder (PTB) won the Project Management...
In a large-scale production system such as building a Boeing 777 airplane, there are more than ten thousand jobs. The interdependence structure among jobs and some jobs' delay's influence on the other jobs in different manufacturing areas are critical information to understand the status of their area. Relationship among groups of jobs may help us find the root cause of problems, to estimate resource...
Agent-based simulation (ABS) is a relatively recent modeling technique that is being widely used to model complex adaptive systems by many disciplines. Few full length courses exist on agent-based modeling and a standard curriculum has not yet been established, but there is considerable demand to include ABS into simulation courses. Modelers often come to agent-based simulation by way of self-study...
There is a growing body of knowledge describing the economic and social challenge faced by the United States because of the small (14%) and decreasing number of students pursuing Science, Technology, Engineering, and Mathematics (STEM) majors. We propose a simple two-period, agent-based simulation based on social impact theory to predict the % yield of STEM majors. The model indicates that changes...
This panel seeks to initiate a discussion within the modeling and simulation community about the way we teach conceptual modeling for simulation with the view of bringing about improvements. The challenge addressed is how to educate and equip the novice analyst to become a professional rather than letting him become an artist - being very much the current practice. The need for professionalism is...
Using case studies helps learning and understanding complex issues in operations and supply chain management studies but preparing models for indepth exploration of case studies is time consuming and requires model-building skills. In order to address these issues, an environment for analyzing case studies is developed. The process-oriented approach is used as a basis for analyzing operations and...
Product and service supply chains are usually complex and difficult to manage. Making students of supply chain management (SCM) courses realise these complex principles of real life problems is not as easy. Business games played in the class or in computer labs is a pedagogical way which assists the understanding of theories, put ideas into action and educates in an interactive and enjoyable way....
