Functional Highlights

Production execution in GreyconMill

Production Execution

Register items as they are produced in all the stages of the process. Each registration links the input items and raw materials with the resulting items.

GreyconMill natively understand all the geometry behind the transformations in the process (winding, slitting, sheeting, coating, laminating, and more).

Traceability and Genealogy through all stages, including Geometry

Innovative architecture allows tracking of any converting operation and modelling all processes in the mill easily. This functionality provides assistance in case of a customer claim.

Machine Learning

Machine learning makes it possible to learn from data collected in the MES solution to make predictions, such as reducing product defects. The collection and storage of all of this information presents a huge opportunity to use machine learning for improving a mill’s performance.

This is powered by a lightweight data historian

Bill of Material (BoM) and Consumption Tracking

Save time by downloading the bills of material directly from the scheduling system. Each operation may have multiple BoM’s, meaning one can be used for the pulp mix and another for the color.

Warehouse management in GreyconMill

Warehouse Management

All material is tracked and the position recorded to allow operators (for example, forklift drivers) to know what material to pick up and where to leave it, regardless of its location.

Performance, Costing Analysis And Reporting

All machines have events recorded and reason codes and comments can be left by the operators/shift foreman before leaving the shift.

Production and efficiency reporting per machine can be compared to ideal production, while recipes are used to calculate production costs.

A library of standard reports has been built into the system which can be changed to address specific needs, and more flexibility can be applied by users who can easily create bespoke reports.
