Computer Simulation
Computer Simulation * A software program that runs on any computer that attempts to simulate some phenomenon based on a scientist's conceptual and mathematical understanding of the given phenomenon.
* The scientist's conceptual understanding is reduced to an algorithmic or mathematical logic, which is then programmed in one of many programming languages (Fortran, C, C++, etc.) and compiled to produce a binary code that runs on a computer.
* Have become a useful part of modeling many natural systems in physics, chemistry and biology, human systems in economics and social science and in the process of engineering new technology, to gain insight into the operation of those systems
Areas that Uses Simulation * Designing and analyzing manufacturing systems; * Evaluating military weapons systems or their logistics requirements; * Determining hardware requirements or protocols for communication networks; * Determining hardware and software requirements for a computer system; * Designing and operating transportation systems such as airports, freeways, ports, and subways; * Evaluating designs for service organizations such as call centers, fast-food restaurants, hospitals, and post offices; * Reengineering of business processes; * Determining ordering policies for an inventory systems; and, * Analyzing financial or economic systems.
Model * is a representation of the construction and working of some system * similar to but simpler than the system it represents. * for a simulation study, a model is a mathematical model developed with the help of a simulation software.
Computer Model * is a computer program which attempts to simulate an abstract model of a particular system
Why use a model? * cheaper * safer * saves time than real system
When to use simulation? * systems that changes with time * systems that involves randomness
