Self-assessment Task 2 – Industrial Process Simulation (Java)

Md Shariful Islam - 7213424

Overview

This project implements the UML model provided in the task using Object-Oriented Programming in Java.
It simulates industrial processes in a warehouse, where operations are performed by Autonomous Guided Vehicles (AGVs).

Implemented Classes

1. IndustrialProcess

• Holds a list of operations (IOperation).
• Provides methods to:
  • Calculate total process duration.
  • List required AGVs.
  • Calculate total energy consumption.

2. IOperation (Interface)

• Defines an operation with:
  • ID, Description, NominalTime, Resources (AGVs).
• Methods: setData(), getData(), getDurationMinutes().

3. BaseOperation (Abstract Class)

• Implements common parts of IOperation.
• Stores metadata and AGV assignments.

4. LoadUnloadOperation (Concrete Operation)

• Models loading/unloading tasks with fixed duration.

5. TransportOperation (Concrete Operation)

• Models transport tasks.
• Duration = distance ÷ AGV speed (+ overhead).

6. AGV

• Represents an autonomous vehicle.
• Attributes: battery, consumption, chargingTime, speed, position.
• Provides energy usage calculation.

Simulation

• Two example processes created:

  • Inbound Receiving (Dock → Transport → Storage).
  • Outbound Picking (Rack → Transport → Packing).

• Each process prints:

  • Operation details (time, AGVs).
  • Total duration.
  • Distinct AGVs required.
  • Total energy consumed.

• A batch simulation combines processes and prints overall statistics.
