Simulation : Stochastic Programming
Simulation : Stochastic Programming DEFINITION Simulation is a representation of reality through the use of model or other device, which will react in the same manner as reality under a given set of conditions. CLASSIFICATION OF SIMULATION MODELS Simulation models are classified as: (a) Simulation of Deterministic models: In the case of these models, the input and output variables are not permitted to be random variables and models are described by exact functional relationship. (b) Simulation of Probabilistic models: In such cases method of random sampling is used. The techniques used for solving these models are termed as Monte-Carlo technique. (c) Simulation of Static Models: These models do not take variable time into consideration. (d) Simulation of Dynamic Models: These models deal with time varying interaction. ADVANTAGES OF SIMULATION Simulation is a widely accepted technique of operations research due to the following reasons: *
