GPSS ALINA

It is a powerful general purpose computer simulation environment designed for simulation professionals. It is a comprehensive modeling tool covering both discrete and continuous computer modeling, with a high level of interactivity and visual presentation of information.

It has such advantages as:
- Multitasking
- Virtual memory usage
- Interactivity
- Graphical user interface
- Visualization of the modeling process
- High performance translator
- Ability to input and output data during the simulation
- Saving running simulation processes with the possibility of subsequent loading and continuing execution
- Programmable experiments with automatic data analysis;
- Automatic generators of screening and optimizing experiments;
- Automatic integration of ordinary differential equations of any order;
- Batch mode with controlled exit from the application;
- Ability to dynamically call functions from external files.

GUI GPSS Studio

The modeling core of the system remains the GPSS ALINA simulation language.

The fundamental principles implemented in the GPSS Studio environment are:

• A unified research space, consisting in automating the actions of the researcher throughout the entire process of simulation research. All input data, models and results are combined for each model as a single project.
• Simplification of interaction with the model in the process of research and providing the researcher with convenient, visual and customizable interfaces for the subject area.
• Provision of graphical and other tools to enable researchers of different backgrounds to construct models and conduct simulation studies.
• Opportunities for mass use of models through the creation of simulation applications focused on the subject area.

The current set of features of the GPSS Studio environment allows you to: create hierarchical simulation models in a visual editor using the general-to-specific and specific-to-general approaches, or a combination of both; generate new logic using GPSS code blocks; debug and execute models; analyze simulation results; carry out single experiments and series of experiments; perform detailed monitoring of variables during the simulation; create an animation video and create an independent simulation application for the customer.
