Dump Truck Problem Simulation

Quick Start

This project is an implementation of the Dump-Truck problem simulation example of Discrete-Event System Simulation 4th edition written by Jerry Banks, John S. Carson II, Barry L. Nelson and David M. Nicol .

In this example we have some truks which are in a weghing queue. Also there is a scale which they should use, after these tasks, they should go back and repeat the tasks again.

In this project we are simulating this situation to find out how much time they spend in weghing queue and scale queue.

In order to run this project we need some tools which you can see below.

Qt

This project is written in Qt, so you need to install Qt to run this project.

https://qt.io

You don’t need any other tools to run this project. Just open up DiscreteEventSystemSimulation.pro in Qt Creator and run the project.

Class Description

Here you can see a summary about the code.

UI Classes

There is some classes which are used for user interface.

• MainWindow which is the main application window that you can input data into.

• DialogSimulation which is the window that shows the result of the simulation.

• DialogCharts which is the window that will show statistics charts.

Simulation Items Classes

Some classes are used as simulation items.

• DumpTruck which will act as a truck.

• Loader which will act as a truck loader.

• Scale which will act as a truck scale.

These items are used due code as our problem items.

Queues

We have some queues in our problem which we have relative classes for all of them.

• Queue which is a base class for other queues.

• LoadingQueue which will be used for keeping trucks that are waiting for loader.

• WeighQueue which will be used for keeping trucks that are waiting for weghing.

These are holding trucks.

Event Management Classes

There is some classes for managing events.

• Event which is a general type for handling events for every truck.

• FutureEventList which will manage all events that are waiting for trucks.

These events actually will generate our result by passing of time.

Other Classes

• CumulativeStatistics this class will hold the result of simulation iterations in a time based manner.

• DataProvider this class will be used to generate required data of simulation iterations.
