Traditionally, this optimization has considered operations related costs such as sourcing, production, transportation, inventory at each site in the network. Quality related costs were either ignored or considered indirectly. In a previous work, we showed how Cost of Quality (COQ) functions can be used as a viable indicator of the level of quality at each site and integrated in supply chain network design (SCND) models. This results in a non-linear MIP model, which poses challenges to solve. In this work, we develop a gradient-search based solution procedure to solve the model effectively for practical implications. The integration of COQ functions allows managers to explicitly consider the maturity levels of both internal sites (plants) and external partners such as suppliers or subcontractors. More importantly, it can be used as an additional metric by which the partners are measured during the annual evaluation process to see if they have progressed in their maturity levels, i.e. in mastering the costs of quality. COQ also opens a new avenue of research in SCND as the model and hence the solution procedure will vary based on the different ways COQ functions are incorporated in the model.
