Vending Machine Assignment - AI Course, Semester 1, University

This assignment delves into the design and analysis of a vending machine system using Artificial Intelligence principles. The document outlines a use case diagram, detailing the various functionalities of the machine, including coin insertion, validation, and drink dispensing. The assignment emphasizes the importance of non-functional requirements, which are crucial for the proper functioning of the system. The provided solution explains the processes involved in each use case, such as the validation of inserted coins and the selection of drinks, and also includes the exception handling for each process. The assignment aims to provide a practical understanding of how AI principles can be applied to real-world systems, such as vending machines, and to help students understand the system design, requirements and validation.
