What is a simulation model?
The model is representation of an object, concept or system. The simulation shows the expected functioning of a system based on the system. The model can be physical or abstract and both types can be static or dynamic - that is, they remain the same or change over time.
An example of a static physical model is a model of water molecule, with two small hydrogen "balls" glued short sticks on both sides of the "ball" oxygen. This model does not change over time. Another physical model is the water tank with sand, which shows the effect of wind and water movement. In this dynamic model, sand and water show patterns that depend on the intensity and direction of the wind with time. In most simulation models there is an element of dynamics.
When creating a simulation model, three elements are identified: parts of the system, interaction between parts and the number and nature of inputs. The model is basically created by each of them, with decisive aspects and ignored small aspects. Then it is developed simulationModel for the whole system.
For example, to simulate the working process of the factory procedure, one machine can be modeled as an element that requires a certain time to create a particular part, while another machine takes a different amount of time. The time to move parts between machines can be ignored for machines that are close together. Number, rate and time when raw materials and work orders come to the factory. Based on all these simulations, it determines whether the factory output meets the demand.
Computers are increasingly used for simulation. Some simulations can be done with standard simulation programs and others require special software to be written. Models for parts, interaction of parts and inputs are into the program. The program then starts the simulation model and adds outputs over time and often shows these outputs graphically. On computers you can try simulations involving thousands or millions of elements and bridging a sizesneak time intervals. Simulations of planetary development or advanced military maneuvers are some examples.
Traditionally, the simulation model was mathematical. For example, the raw materials coming to the factory would be approximated as coming at fixed intervals. Computers can now perform more realistic simulations using a script that has events that are similar to the actual situation or even accurate record of the real situation.
