Simple elevator control system

Setup and run

1. Download repo with git client or with go tools go get github.com/mmigacz/elevator-control
2. Build application with make build
3. Run application ./elevator-control [number_of_lifts]. The application starts by default with 2 elvators. Alternatively you can run app directly with go with the following command go run main.go [number_of_lifts]

After start the application will prompt you a command line. Type anything + Enter to get list of available commands.

• status - displays list of elevators

  #id - elevator's id
  #floor - current flor
  #open - true if doors are open on the current floor
  #direction - stop|up|down - current state of the elevator
  #upq - lenght of the queue with stops above
  #downq - lenght of the queue with stops below
  id:[0], floor:[4], open:[false] direction:[up], upq:[1], downq:[0]
  id:[1], floor:[0], open:[false] direction:[none], upq:[0], downq:[0]
  

• step - next step of the simulation

• update elevator_id floor_id - add destination floor_id to the elevator_id. Reflects pressing a button in the elevator.

• pickup floor_id direction - pickup any lift on floor_id in to the direction (-1 down, +1 up). Reflects pressing a button on the corridor

• exit - exits application

How it works

On pickup

1. Than take a first elevator on way (up/down)
2. If no elevator on way, than take the closes waiting
3. If no waiting, than schedule the first one
