What is about Today?
Modeling & simulation is use of the physical, mathematical or logical representation of a system , entity or process and these models reduces the development time and cost of the system and it optimizes the design. Simulation is the imitation of the real-world process or system. To simulate something, it requires a model to be developed, and these model represents the key characteristics, behaviors and functions of the selected system or process.Modelling an act of building a model and Simulation is act of using a model.Simulation software is based on the process of modeling a real phenomenon with a set of mathematical formulas.
Advantages:
- Allows to understand how the system operates in real-time system in virtual environment.
- Easy to make changes in to the system and their effect on the output.
- Can determine the system requirements by applying different configurations.
- Performing bottleneck analysis.
- Understand all the interactions and analyze the effect.
- External noise can be applied to system to get real-time environment.
- Model can be simulated with respect to time - Dynamic simulation.
- From simulation code generation is easy, many tools are available.
Disadvantages:
- To design a model requires domain knowledge and experience.
- Its a time consuming process to optimize the model.
- Expensive as it needs costly tools.
- Requires high processing system to perform simulation on software tool.
