  2. 2. ModelModel is simplified representation of relevant entities of some specific reality and theircharacteristics.In general model can be classified as follows:  Iconic models  Analogue models  Symbolic models1. Iconic ModelIconic Model is representation of some specific entity.ClassificationIconic Models can be represented in:- Two DimensionsExample: drawings, photos etc.- Three Dimensions:Example: scale model2. Analogue ModelAnalogue Model uses a set of properties to represent the properties of real life system.Example:Through diagramsClassificationAn Analogue Model can be built through:- Two Dimensional Visualization:Charts, Graphs, Diagrams- Three Dimensional Visualization:Analogue Devices
  3. 3. 3. Symbolic ModelSymbolic Model is representation of entities of a system through symbols.Symbols can be:- mathematical- logical- computer programsDeterministic ModelModel which provides a close-form solution to a problem and it does not contain elementof probability. Deterministic models involve optimization.ExamplesLinear programming, non linear programming, network optimization, dynamicprogrammingStochastic ModelThis model contains the element of probability.Examples:Queuing theory, stochastic processes, reliability theory, and stimulation techniques.
