Study Notes
Input Modeling for System Simulation and Modeling
- Input models are essential for driving simulations and include distributions such as inter-arrival time, service time, demand time, lead time, and time to failure of a component.
- Developing a useful model of input data involves four steps.
- The first step involves collecting data from the real system of interest, which can be time-consuming and resource-intensive.
- In situations where it is not possible to collect data, expert opinion and knowledge of the process are relied upon to make valid guesses.
- The second step is to identify a probability distribution to represent the input process.
- When data are available, the probability distribution can be identified based on the data collected.
- Choosing an appropriate distribution for input data is a challenge in any simulation model development.
- It may not be possible to collect data in a short duration, making expert opinion and knowledge of the process crucial in such situations.
- The input models are crucial for simulating the behavior of the system accurately.
- The distributions of inter-arrival time, service time, demand time, lead time, and time to failure of a component are examples of input models.
- The development of a useful model of input data requires a comprehensive understanding of the real system and the identification of appropriate probability distributions.
- The accuracy of input models significantly impacts the accuracy of the simulation model.
