Simulating interactions in production and packaging operations is creating financial returns for food processors, boosting production and saving time by preventing unnecessary investments. New software from the Lanner Group can simulate both discrete and continuous processes. At General Mills' (GM), process engineers prove its benefits when they have a new project proposal or question a process improvement.

"To facilitate simulation use by our process engineers, we created a library of equipment templates that simplify the creation of a simulation model," says Malcolm Beaverstock, manager of advanced control and simulation at GM. Templates define components of plant operations, containing a definition of the equipment as well as operating and downtime characteristics.

"We use Witness [software] to understand, as well as improve, our operations" explains Beaverstock. "We had one plant switch from a manual material transport system to an automated one. However, the automated system didn't work as well as the old manual one." Productivity only reached 80 percent compared to the manual system. That was puzzling because the new line was supposed to be more flexible, require less labor and reduce waste.
