Elevator Simulator

General

Simple Java console program that simulates the working of an elevator in a building. The program is parameterized with positional arguments:

F  number of floors in the building
t  unit of the simulation time, i.e. the time in seconds needed to move one floor by the elevator
p  the probability of a passenger appearing in unit t on a random floor with the intention of traveling to random floor

The program graphically visualizes the state of the entire system in every unit of time t (location of the elevator, current source and destination floors, passengers waiting on each floor etc.).

Elevator algorithm and architecture

Elevator algorithm

• no requests => elevator stay at the current floor
• elevator move in one chosen direction from src to dest
• if the request is on src->dest track, elevator stops and service it (take/release passengers)
• request is send when passenger takes elevator (src) or go inside elevator (dest)
  
  

Architecture

Run

1. Make sure you have installed JDK

javac -version

2. Clone the repository and compile all .java files

git clone https://github.com/ksalekk/elevator-simulator.git
cd ./elevator-simulator
javac -d bins ./src/edu/ksalekk/elevatorsimulator/*.java
cd ./bins

3. Run test program with specified parameters (remember not to type .class extension)

java edu/ksalekk/elevatorsimulator/ElevatorSimulatorTest 5 2 0.3

You can also run the program in your IDE.
