Abstract

SEE WHY and WITNESS are companion products for visual interactive simulation. SEE WHY is a general purpose discrete event simulation system that offers special integrated features for graphical display and run time interaction. It also provides user programmable extensions to both the display and interaction capabilities. These facilities are highlighted in the discussion of SEE WHY.WITNESS has been developed from SEE WHY. It is a simulation program for manufacturing operations that fully exploits the visual and interactive capabilities of SEE WHY in bringing simulation modeling to the non-specialist. The phases of WITNESS modeling are covered in some detail as well as the characteristics of the user interface. The paper concludes with an overview of the ability to extend the WITNESS program with an interface to SEE WHY.
