Initial data for planning:
- Paper machines with parameters: width, edge, production capacity, and many more
-Orders portfolio with parameters: format, diameter, deadline, required volume, density, and many more
Technological requirements taken into account
- Cutting width does not exceed the paper web width (with an edge)
- The rolls in the same cut have the same density, grade, and diameter
- Total number of rolls in a cut does not exceed the limit
- The number of different rolls in a cut does not exceed the limit
- Ability to prohibit placing a roll on the side of a cut
- Specific paper machine(s) for an order
- Minimum deviation from the diameters of a cut
- And other – in agreement with the Customer
Results
- Increased yield due to trim optimization by 1 ... 1.7%
- Reduced equipment downtime by 3 ... 4%
- Ability to quickly recalculate plans to account for dynamically changing production parameters
- Increased yield of priority products (e.g., export contracts, priority customers, etc.)
- Minimization of losses when it is impossible to comply with the volumes or terms of orders execution
The system can be improved to account for other requirements, parameters, etc
