GPSS

GPSS, or General Purpose Simulation System, is a simulation programming language that was developed in the 1960s. It is used to model and simulate systems in a wide variety of fields, including manufacturing, logistics, queuing, and computer systems. GPSS is a very versatile language, and its popularity is due in part to its ease of use. It has a simple, English-like syntax that makes it easy to read and understand. GPSS also has a large number of built-in functions that allow users to quickly create models without having to write a lot of code. Despite its age, GPSS is still in use today by many organizations. It is a powerful tool for understanding and optimizing complex systems.
