Bilkent University - IE 324 Simulation AIRPLANE BOARDING • How to determine the best method? • What performance metrics to decide? • Things to think about: • Passenger movements / lineup order • Single, double door usage? • Different type of passengers (young, old, with babies/kids, disabled…) • Passengers with/without carry-on • How to make the analysis?
Bilkent University - IE 324 Simulation SYSTEM A set of interacting components or entities operating together to achieve a common goal or objective. Examples Manufacturing facility Bank operation Airport operations (passengers, security, planes, crews, baggage) Transportation/logistics/distribution operation Hospital facilities (emergency room, operating room, admissions) Computer network Freeway system Business process (insurance office) Fast-food restaurant Supermarket Theme park Emergency-response system REAL WORLD SYSTEMS OF INTEREST ARE HIGHLY COMPLEX!!!
Bilkent University - IE 324 Simulation System Experiment with the actual system Experiment with a mathematical model of the system Mathematical Analysis Simulation • Measure/estimate performance • Improve operation • Prepare for failures IE 325 IE 202 IE 303 … IE 324 Experiment with a physical model of the system WHY AND HOW TO STUDY A SYSTEM?
Bilkent University - IE 324 Simulation MODEL • An abstract and simplified representation of a system • Not an exact re-creation of the original system! • Specifies assumptions/approximations about how the system works • Translates them into a set of logical and mathematical relations • If model is simple enough, study it with Queueing Theory, Linear Programming, Differential Equations... • If model is complex, Simulation is usually the only way!
Bilkent University - IE 324 Simulation WHAT IS SIMULATION? • The imitation of the operation of a real-world process or system over time… • Most widely used tool (along LP) for decision making • Usually on a computer with appropriate software • An analysis (descriptive) tool – can answer what if questions • Applied to complex systems that are impossible to solve mathematically • This course focuses on one form of simulation modelling • Discrete-event simulation modeling
Bilkent University - IE 324 Simulation WHAT IS SIMULATION? Simulation models seek to: • Describe the behaviour of the system • Construct theories or hypotheses based on the observed behaviour • Use these theories to predict the future behaviour, that is, the effects that will be produced by changes in the system or its method of operation
Bilkent University - IE 324 Simulation ORIGIN OF SIMULATION • Lie in statistical sampling theory, e.g., random numbers, random sampling (Before the 2 nd world war) • Monte Carlo simulation (During the 2 nd world war) • Modern Applications (After the 2 nd world war)
