Question

Advantages and disadvantages of validation in simulation

Answer 1

Advantages and Disadvantages of Simulation in Operation Research

Advantages

Simulation is best suited to analyze complex and large practical problems when it is not possible to solve them through a mathematical method.Simulation is flexible, hence changes in the system variables can be made to select the best solution among the various alternatives.In simulation, the experiments are carried out with the model without disturbing the system.Policy decisions can be made much faster by knowing the options well in advance and by reducing the risk of experimenting in the real system.

Disadvantages

Simulation does not generate optimal solutions.It may take a long time to develop a good simulation model.In certain cases simulation models can be very expensive.The decision-maker must provide all information (depending on the model) about the constraints and conditions for examination, as simulation does not give the answers by itself.

Answer 2

Answer:

From the standpoint of the model's intended uses, validation is the process of establishing how well a simulation model and the data it uses to represent the real world.

   Advantages and disadvantages of validation in simulation

Advantage :

• When a mathematical approach cannot be used to address an issue, simulation is best suited to study complex and huge practical situations.

• Since simulation is adaptable, modifications in the system variables can be made to find the optimum option out of a range of options. In a simulation, the system is not disturbed while the experiments are run on the model.

Disadvantage:

• Simulation does not produce the best results.

• A quality simulation model may take a while to construct.

• Simulator models can be highly expensive in some circumstances.

• As simulation cannot supply the answers on its own, the decision-maker must provide all information regarding the limitations and conditions for analysis.
