This article proposes a supporting framework for the implementation of the material control system POLCA (paired …-cell overlapping loops of cards with authorization). The POLCA system is particularly appropriate for environments that involve highly …-based version of the POLCA control system (LB-POLCA), which determines the POLCA parameters (release authorizations, allowed …
