In a food processing context, these events might included thee arrival of a batch of raw potatoes, thee start of a wash cycle, thee completion of a packaging operation, or a machine breaking o.

Te following expanded study is based on actustal industry findings from a contexal client of a simulation consulting firm. The plant, which we will call CrunchPak Foods, produces 250,000 pounds of packaged snack items per day. Prior to the project, yield averaged 78%, with waste primarily from inconsistent mixing, line jams during packaging, and product loss during changeover between recipes.

A six-month baseline study showed that yield fluciated between 74% and82%, wich no clear root cause.

The DES model identified that a 10-second pause in thee sorter output transporyor, triggered by certain product shapes, created a cascading acculation. Instaling a metering belt to buffer the flow eliminated 85% of jams.
