Rand Model Designer is a comprehensive and efficient software solution which aims to offer users the means of creating and running in an integrated environment various models for dynamical systems.

Following a simple installation process with no particular events to speak of, users can launch the application and begin working it with.

It features a basic and straight-forward interface, making use of several panels, namely the 'Project Manager', the 'Class Identifier' and 'Behavior Chart' that enables users to view their project in detail, as well as adjust various properties, in order to generate different effects.

When creating a new project, users will need to input its name and save location, then choose the preferred 'Model Type' between 'Continuous Elementary Object', 'Block Diagram' and 'General', depending on their individual needs.

From the 'Project Manager' section, users can 'Add Icons', 'Save Model as Class' or 'Add Superclass'. Moreover, they can create 'New Parameters' or 'Transform' an item to a 'Hybrid Object', 'Compound Object' or 'Isolated System'. It also allows them to insert 'New Variables', 'New Constants', 'New Functions' or 'New Procedures'.

Using the 'Equation Editor', users can input the mathematical calculations that need to be performed in order to create the current model, while the 'Formula Calculator' enables them to input the 'Class', 'Expression' and obtain the corresponding 'Result'.

After inserting all the required parameters, preferences and other necessary elements, users can 'Run Visual Model', which will present them with a 'Statistical Experiment Model' window, in which they can get a detailed view of the equivalent 'Phase Diagram', 'Bar Chart', '3D Animation' and other items.

To conclude, Rand Model Designer is an advanced and professional program that provides users with the proper instruments to design and simulate the running of dynamical systems models, in a controllable environment.
