SYST 683 - MODELS, GAMING, AND SIMULATION
COURSE OVERVIEW: This course will focus on the use and characteristics of combat simulations as aids to decision-making. Principles of good analysis using combat models will provide the overall theme of the course. It will include discussion of techniques to model attrition, acquisition, movement, battlefield environment, command and control, communications, intelligence, air-to-air combat, and decision-making. The future of combat simulations will be discussed, including Advanced Distributed Simulation (Distributed Interactive Simulation and High-Level Architecture).
COURSE GOAL: The overall goal of the course is to
prepare students to be good “consumers” of military simulation products, for
example, as military decision-makers, advisors to decision-makers, or as
critical observers of the acquisition, research, or operational planning
processes within the
1. Students will be familiar with the definitions and taxonomies of models, simulations, and wargames.
2. Students will understand the purposes of combat models as aids to decision-making, including principles of proper use, formulation of measures of effectiveness, analysis of results, and common pitfalls and abuses in the construction and application of combat models.
3. Students will understand strategies for representing combat such as stochastic versus deterministic modeling, event-based versus time-stepped simulation, aggregation, distributed versus standalone simulation, and closed versus human-in-the-loop simulation.
4. Students will understand techniques for representing acquisition, attrition, movement, battlefield environment, command and control, communications, intelligence, air-to-air combat, and decision-making.
5. Students will be familiar with the functions of major components of air-land combat simulations, using as examples algorithms employed by Eagle, a US Army corps-level combat simulation, and THUNDER, a USAF theater-level air combat simulation. These components will include command and control, direct fire, indirect fire, acquisition, sensors and intelligence fusion, terrain, mobility/countermobility, air and air defense, logistics support, and possibly others based on student interest.
6. Students will demonstrate an understanding of the use of combat models by conducting an analysis of the impact on force effectiveness of a modernized (notional) tank.
7. Students will be familiar with the concept of Advanced Distributed Simulation, including Distributed Interactive Simulation and High-Level Architecture.
8. Students will be familiar with composable, object-oriented, parallel, and distributed approaches in combat simulations.

*For use in Project Part I
Concept: Each student will use combat models to analyze a notional modernized tank to determine its impact on force effectiveness.
1. A high-resolution tank-on-tank combat simulation. This model will be provided by the instructor. It is written in Pascal, and will run on an IBM-compatible PC.
2. Attrition and acquisition data to describe the modernized tank and the tank it would replace, and data for a set of other friendly and threat weapon systems.
3. A simple Lanchester-based low-resolution model. This model will be implemented by each student in a spreadsheet or other format as desired.
4. Statistical tools as available in Excel or other spreadsheets.
Requirement: Students will develop attrition rates for Blue (friendly) and Red (threat) weapons using a high-resolution simulation and statistical techniques (Part I). They will then build a Lanchester-based spreadsheet model of aggregated combat and use the attrition rates developed in Part I to assess the overall contribution of the modernized tank to force effectiveness (Part II).
Optional Alternative to Part II: Student will present a topic based on his/her own experience or research relevant to Military Modeling and Simulation, but not covered in the course.
