An economic production quantity model with consolidating shipments of imperfect quality items: A note

In this note, we correct some typos that appeared in Yassine et al. {Yassine, A., Maddah, B., Salameh M., Disaggregation and consolidation of imperfect quality shipments in an extended EPQ model, International Journal of Production Economics 135 (2012) 345–352}, specifically, for one of their models that considered consolidating shipments of imperfect quality items across multiple production cycles. In addition, we present a heuristic approach to find a good solution for this model. The performance of heuristic solution is illustrated with numerical examples.
