Step 8 − Induce experimental conditions on the model and observe the result.įollowing are the steps to perform simulation analysis. Step 7 − Select an appropriate experimental design as per requirement. Step 6 − Create a document of the model for future use, which includes objectives, assumptions, input variables and performance in detail. Step 5 − Validate the model by comparing its performance under various conditions with the real system. Step 4 − Develop the model using network diagrams and verify it using various verifications techniques. Step 3 − Collect and start processing the system data, observing its performance and result. Step 2 − Design the problem while taking care of the existing system factors and limitations. Step 1 − Identify the problem with an existing system or set requirements of a proposed system. Following are the steps to develop a simulation model. Simulation models consist of the following components: system entities, input variables, performance measures, and functional relationships. The historical perspective of simulation is as enumerated in a chronological order.ġ940 − A method named ‘Monte Carlo’ was developed by researchers (John von Neumann, Stanislaw Ulan, Edward Teller, Herman Kahn) and physicists working on a Manhattan project to study neutron scattering.ġ960 − The first special-purpose simulation languages were developed, such as SIMSCRIPT by Harry Markowitz at the RAND Corporation.ġ970 − During this period, research was initiated on mathematical foundations of simulation.ġ980 − During this period, PC-based simulation software, graphical user interfaces and object-oriented programming were developed.ġ990 − During this period, web-based simulation, fancy animated graphics, simulation-based optimization, Markov-chain Monte Carlo methods were developed. It is an act of using a model for simulation. In other words, simulation is the process of using a model to study the performance of a system. Simulation of a system is the operation of a model in terms of time or space, which helps analyze the performance of an existing or a proposed system. In other words, modelling is creating a model which represents a system including their properties.
This model is similar to a real system, which helps the analyst predict the effect of changes to the system. Modelling is the process of representing a model which includes its construction and working.
