Cavalier Bremworth - Control Solution



Cavalier Bremworth - Batch Control

• Batches are specified from the Planning Department, and downloaded to the PlantScape system.

• Operators login before operating machines. The Batch ID is checked, and the operator productivity and machine efficiency is tracked.

• Each machine has a selection of “downtime” codes for tracking machine performance. Statistical data is reviewed to determine problem machines, and focus on reducing bottlenecks.

• Each machine has its own "Batch Control" program that is designed to guide the operator when starting/stopping batches.

• Each “Batch Control” program has logic steps and plant feedback to minimize error and maximize productivity.









Cavalier Bremworth - Summary

• The Control System solution has been in operation for nearly 6 years and keeps on expanding

• Cavalier Bremworth achieved excellent results:

– Reducing the number of operators and maintenance staff by 50%

– Increasing productivity by over 150% (by identifying machine downtime trends, focusing on Operator training, and providing operators with productivity information).

– This is a unique system, tailored for this application. But the principles can be applied to any industry.
