The user can select individual variables which are connected between the Plant-Wide Optimizer and APC/optimisation layers. This gives considerable flexibility to specify only the critical, enterprise-wide variables, without requiring detailed modeling of lower level constraints and relationships.

Honeywell Plant-Wide Optimizer performs a comprehensive check of potential constraints in the lower level controller (ie. ensures feasibility of any optimiser generated solution). Additionally, Honeywell Plant-Wide Optimizer utilises standard Forge APC components and connectivity.
