Method and apparatus for load balancing manufacturing execution among optical laboratories
A method and apparatus are provided for optical manufacturing laboratories (OMLs) obtaining a plurality of performance indictors (PIs). The PIs are published or otherwise distributed among one or more participants (e.g., one or more ECPs and/or an administrative team of the OMLs).

A combination of the logic blocks together with the plurality of PIs are applied as inputs to the selection rules (e.g., routing logic), which then output rankings of the OMLs in accordance with the priorities of the respective orders. The orders are then routed to an optimal combination of the OMLs based on the results from the selection rules.
