# ELEVATOR SCHEDULER PROJECT



## Introduction:

In Iteration 4 we added code for detecting and handling faults. To this end, we added timing events so that if the timer goes off before an elevator reaches a floor, then our system should assume a fault (either, the elevator is stuck between floors, or the arrival sensor at a floor has failed). We should detect whether a door opens or not, or is stuck open.

## File Descriptions:

Floor class - This class represents the current status of the floor. It takes the information from the table of the text file and processes it.



FloorSubsystem class - This is the client class that reads events in the format: Time, floor, floor direction, and elevator button. Each line of input is to be sent to the Scheduler.



Scheduler class - This class connects the elevators to the floor. It calls an elevator to a floor and adds the elevator to a queue when there is work to be done. It is only being used as a communication channel from the Floor thread to the Elevator thread and back again.



Elevator class - This class moves elevator between floors based on the data gotten from the Scheduler class.



ElevatorQueue class - This class hooks the elevators up to the queue system.



Main class - This class is used to run the program.



FloorTest - This is a test class that tests the methods in the Floor and FloorSubsystem classes.



ElevatorTest - This is a test class that tests the methods in the Elevator class.



SchedulerTest - This is a test class that tests the methods in the Scheduler class.



InputTable.txt - A text file filled with random data entries to be parsed into the scheduler.



## Set-up Instructions:

- To run the program on a single device, simply run the Main class.

- To run the program on separate devices, divide into these 3 groups and modify their InetAddresses:

  1. Floor, FloorSubsystem, InputTable.txt, States

  2. Scheduler, States

  3. Elevator (would also need to access the number of floors from the floor class), ElevatorQueue, States



## Test Instructions:

Run the Test methods in the test classes all on a single device (ElevatorTest, FloorTest, SchedulerTest).



## Packet Byte[] Information:

- Direction values: 1 = UP, 2 = DOWN

- elevatorState values: 0 = IDLE, 1 = UP, 2 = DOWN, 503 = OUT OF SERVICE, 404 = UNKNOWN STATE, 504 = FORCE DOOR CLOSE

- stillTasking/makingStop values: 1 = Yes, 0 = No

- handlingDoor values: 1 = opening, 2 = holding, 3 = closing, 4 = moving, 0 = closed

- Floor Subsystem Sent Message: [floorNumber, direction, destinationFloor]

- Floor Received Message: [floorNumber, elevatorNum, direction]

- Elevator Sent Message: [elevatorState, handlingDoor, floorNumber, elevatorNum, direction]

- Elevator Queue Received Message: [floorNumber, direction, destinationFloor, elevatorNum]
