Event Driven Simulation

Description

An event-driven simulation is a computer program that mimics the behavior of people or objects in a system in response to events that occur at certain times.

Specifically, this program will simulate a simply, daily activity of people in a Bank.

The major activities that we are tracking are:

1. For customers:
   • Customer arrival.
   • Customer leaving bank.
2. For Bank tellers:
   • Teller's service for one customer.
   • Teller's completion of service.
   • Teller's break.

Purpose

1. Measure the average amount of time people spend between arriving at the bank and leaving the bank.
2. Compare the efficiency between two possible bank setup:
   • One customer line for each teller.
   • One common line for all tellers.
