Comments on preservation technology investment for deteriorating inventory

Recently, in the Preservation technology investment for deteriorating inventory, by the International Journal of Production Economics, Hsu et al. (2010) in a press proposed a deteriorating inventory with time-dependent partial backlogging rate. In addition, the retailer is allowed to invest on the preservation technology to reduce the rate of product deterioration. However, the property of the retailerʹs unit time profit of Hsu et al. (2010) has remained unexplored. In this comment, we complement the shortcomings of this paper.
