The supplier produces the item (raw...

This paper deals with multi-stage lotsizing models for imperfect production processes. The e€ ect of imperfect quality on lotsizing decisions and e€ ect of inspection errors are taken into consideration in the proposed models. Numerical examples are presented for illustration purposes. The developed models are very helpful for justifying quality assurance and quality improvement e€ orts.

We consider a three-level distribution network involving a raw material supplier with imperfect quality, a manufacturer and several retailers. A production-inventory model accompanied by a partial backlogging approach is developed by considering random disruptions. Any batch received from the supplier is inspected by the manufacturer and if any flaw is visited, all the goods in the inspected ba...

In this paper, a production inventory model is considered for stochastic demand with the effect of inflation. Generally, every manufacturing system wants to produce perfect quality items. However, due to real-life problems (labor problems, machine breakdown, etc.), a certain percentage of products are of imperfect quality. The imperfect items are reworked at a cost. The lifetime of a defective ...

This study applies periodic preventive maintenance (PM) to a repairable production system with major repairs conducted after a failure. This study considers failed PM due to maintenance workers incorrectly performing PM and damages occurring after PM. Therefore, three PM types are considered: imperfect PM, perfect PM and failed PM. Imperfect PM has the same failure rate as that before PM, where...

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 cy...
