RECOMMENDING WASTE REDUCTIONS AND CREDIT PURCHASES FOR BUSINESS UNITS

In an embodiment, revenue loss functions associated with business units are determined and waste credit constraints associated with the business units are received. A recommended waste credit purchase amount and recommended waste credit reduction amounts associated with the business units are calculated by minimizing a sum of the revenue loss functions and a purchase function, subject to the waste credit constraints, a purchase constraint, and a reduction goal constraint. In various embodiments, the recommended waste credit purchase amount and the recommended waste credit reduction amounts are presented, the amount of waste credits specified by the recommended waste credit purchase amount are purchased, and the business units reduce their waste emissions by their respective recommended waste credit reduction amounts. In an embodiment, the minimization is perfumed via a quadratic programming algorithm.
