A supplement to the EPQ with partial backordering and phase-dependent backordering rate

Wee, Hui-Ming; Wang, Wan-Tsu - In: Omega 40 (2012) 3, pp. 264-266

In this note, we extend Pentico et al. (2011)'s [1] EPQ model where the authors considered two different backordering rates during shortage period; they assumed the backordering rate increases only from the start of production phase. We propose two models that allow the backordering rate to...
