How it works


A Renque model is constructed on-screen by placing server objects on a worksheet and interconnecting the servers by links. During a simulation,  entities are created, which migrate through the network of servers and links, by traveling from server to server on the links. The simulation imitates the progress of a real process in a figurative manner, essentially by the spread of entities across the model.


The heart of the Renque simulation engine is an event calendar. A calendar event performs a logical operation on an entity at a predetermined event time. A simulation starts with a number of initializing events that create the first entities. Other events are added to the calendar by execution of events only. The events are processed sequentially until the event calendar is empty. When a calendar event has been executed, the simulation time jumps to the event time of the next event, hence the name discrete event simulation.


Renque offers a range of additional tools to expand the capabilities of a simulation model. These tools include such things as random number generators, scheduled operations, data management utilities and simulation control by scripting. Their combined application can yield advanced simulation models, suitable for studies on highly complex systems.


Simulation results are retrieved in various manners. Renque provides extensive means for statistics recording, data tabulation and export of results. In addition, a Renque simulation visualizes a simulation by animation. Servers and entities are represented on the worksheet by pictures, and links are displayed by curves. Entity transformations can be watched on the worksheet as they occur in the simulation, which greatly benefits the comprehensiveness of the model and communication of results.
