Question

How can you determine input probability distributions for interarrival or processing time for a system from observed data. Write a brief discussion providing a simple example.

(from simulation with arena 6th edition text book)

Answer 1

Probability Distribution is used for a simulation of uncertain inputs of a system.  Let us consider an example: In a Single Server where operations are performed in a queue and the simulation of a system requires the probability distribution in order to identify the user visit time and services being provided to the user. In this system model, the simulation occurs through probability distribution for producing uncertain inputs. Most of the systems that are used in today times use unpredictable sources. We use probability distribution and empirical distribution for the representation of unspecified source of a system for a given data. Then it is required to adopt a terminology for giving three activities and to find out the suitable distribution of data.
