Applications of SLX

SLX is being used to simulate air traffic control systems at a variety of levels. Such models are written at a very detailed level in order to accurately reflect the operation of the real system.

SLX is being used as the simulation engine in a proprietary assembly line modeling package developed by a major U.S. manufacturer. The modeling package uses Excel-based front ends that allow non-simulationists, e.g., factory foremen, to ask "what if" questions of simulation models.

SLX is being used as the simulation engine in a proprietary modeling package developed on behalf of the U.S. Government for modeling security at points of entry into the United States.

SLX is being used by a U.S. Government agency to evaluate candidate telecommunications protocols. By definition, candidate protocols haven't yet been standardized, so they're not built into off-the-shelf telecommunications modeling packages. Testing many high-traffic scenarios can consume large amounts of computer time. SLX's extremely fast execution pays off in such situations. A 24-hour SLX run might take weeks to run under other software.

SLX is being used to simulate movement of pedestrians. Past applications include simulation of passenger movement at a railroad platform, and current applications include simulation of the flow of attendees at large public events.

SLX has been used to model pneumatic tube delivery systems. Similar to systems used in department stores in the 1950s and 60s, such systems are often used today in hospitals for purposes such as transporting samples to laboratories from their points of collection. The complexities imposed by limitations of topology and physical propulsion constraints place modeling of these systems well beyond the capabilities of the built-in material handling capabilities found in off-the-shelf simulation software.

SLX has been used to model a large intermodal transportation center located in Philadelphia. This model was the first really large (over 30,000 lines) SLX model. It simulated the movement of buses, passenger cars, rail cars, and pedestrians.
