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)

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
