WITNESS is the Interactive Visual Simulation software product by LANNER Group, which concludes more than fifteen years of specialisation, becoming the world's leader (independent analysts ARC 1999). WITNESS is a powerful flexible package, for general use (i.e. not limited to the kind of problem or production context that is being studied), providing dynamic simulation through discreet events for end users.

It contains a great variety of predefined functional elements (objects), that can be selected from the menu or can be programmed in a powerful language. It has got an excellent graphic interface that makes possible to display and to study, graphically and interactively, the model's behaviour while it's being developed or experimented.

In spite of its practically unlimited power and capacity (regarding the number of processes or machinery, jobs, products, components or shifts), it doesn't require a huge computer: it can be used at isolated PCs (Windows) configurations, on nets, workstations and UNIX systems.

In the whole world, there are more than 6,000 WITNESS systems installed in a great variety of sectors, such as:

• the motor industry
• electronics
• feeding, drinks and tobacco
• paper, rubber and plastics
• chemical and pharmaceutical
• aerospace
• engineering
• ports
• airports
• post offices
• banking
