Simulation Projects 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, simulation is the process of using a model to study the performance of a system. It is an act of using a model for simulation.
Modelling & Simulation ─ Advantages
Following are the advantages of using Modelling and Simulation −
Easy to understand − Allows to understand how the system really operates without working on real-time systems.
Easy to test − Allows to make changes into the system and their effect on the output without working on real-time systems.
Easy to upgrade − Allows to determine the system requirements by applying different configurations.
Easy to identifying constraints − Allows to perform bottleneck analysis that causes delay in the work process, information, etc.
Easy to diagnose problems − Certain systems are so complex that it is not easy to understand their interaction at a time. However, Modelling & Simulation allows to understand all the interactions and analyze their effect. Additionally, new policies, operations, and procedures can be explored without affecting the real system.
Modelling & Simulation ─ Disadvantages
Designing a model is an art which requires domain knowledge, training and experience.
Operations are performed on the system using random number, hence difficult to predict the result.
Simulation requires manpower and it is a time-consuming process.
Simulation results are difficult to translate. It requires experts to understand.
Simulation process is expensive.
