.DESLib.DEVSLib.Examples.ATM

Information

This package includes the implementation of an ATM system (Automatic Teller Machine). A complete description of the system and its implementation using the CD++ environment can be found here

Basically, the system is composed by three subsystems:

• CardReader, that receives the inserted card and starts the authorization process.
• Authorization, that validates the card, the PIN and the amount of cash to be withdrawn.
• CashDispenser, that gives the cash to the user.

The CardReader and the CashDispenser are modeled as atomic models, and the Authorization as a coupled model.
The Authorization subsystem is composed by the BalanceVerifier, the PINVerifier and the UserInterface.

Simulation

• cardIn shows the insertions of cards into the ATM.
• cash shows the returned cash to the customer.
• cardOut shows the ejection of the inserted card.
