Abstract: A manufacturing plant treats defectives and non-defectives differently (Wahab and Jaber, 2010). On the basis of this approach, in this technical note, an optimal batch size is determined for the model in Khan et al. (2011a). Furthermore, the model is extended for learning in supplier's quality. These practical extensions of the above model are more in line with the practice in the present-day industry. The numerical results are compared to those in Khan et al. (2011a), and Maddah and Jaber (2008). The proposed model suggests a smaller batch size and lower annual cost than that in Khan et al. (2011a).

Keywords: batch sizing; lot sizing; EOQ; EPQ; imperfect quality; holding costs; learning; economic order quantity; inspection errors; economic production quantity; manufacturing industry; supplier quality.
