In order to make the Economic Production Quantity (EPQ) model more applicable to real-world production and inventory control problems, in this paper we expand this model by assuming that some imperfect items of different product types being produced such as reworks are allowed. In addition, we may have more than one product and supplier along with warehouse space and budget limitation. We show that the model of the problem is a constrained non-linear integer program and propose a genetic algorithm to solve it. Moreover, a design of experiments is employed to calibrate the parameters of the algorithm for different problem sizes. In the end, a numerical example is presented to demonstrate the application of the proposed methodology.

“…Porteus (1986) and Rosenblatt and Lee (1986) were the first two who introduced the concept and developed inventory models to discuss the relationship between an imperfect production process and an optimal lot size. Some similar problems related to quality and lot size have been discussed by several authors such as Schwaller (1988), Paknjad et al (1995), Ouyang et al (1999b), Salameh and Jaber (2000), Ouyang (2000, 2001), Chang (2003), Balkhi (2004), Hou and Lin (2004) and Papachristos and Konstantaras (2006). The above models tackled defective items focusing on lot sizing under an EOQ/EPQ model.…”

This article investigates the impact of inspection policy and lead time reduction on an integrated vendor-buyer inventory system. We assume that an arriving order contains some defective items. The buyer adopts a sublot sampled inspection policy to inspect selected items. The number of defective items in the sublot sampling is a random variable. The buyer's lead time is assumed reducible by adding crash cost. Two integrated inventory models with backorders and lost sales are derived. We first assume that the lead time demand follows a normal distribution, and then relax the assumption about the lead time demand distribution function and apply the minimax distribution-free procedure to solve the problem. Consequently, the order quantity, reorder point, lead time and the number of shipments per lot from the vendor to the buyer are decision variables. Iterative procedures are developed to obtain the optimal strategy.

“…Wu and Ouyang (2000) considered the potential for an arrival order lot to contain some defective items and the number of defective items in a sampled sub-lot to be a random variable. Currently, several relevant papers exist that study EPQ models for items with imperfect quality such as Ouyang et al (2002), Chiu (2003), Chang (2003), Balkhi (2004), Hou and Lin (2004) and Papachristos and Konstantaras (2006). These models determine an optimal policy from the perspective of either the retailer or the supplier only.…”
