Ever since the basic Economic Order Quantity (EOQ) model was introduced, several researchers and academicians extended and/or altered it, to reduce its unrealistic assumptions and make it more suitable and appropriate to the real world. The traditional EOQ Models assume constant demand and...

Nowadays, companies are collaborating and forming supply chain partnerships under a certain scheme, such as a vendor-managed inventory scheme. The collaboration increases the supply chain's visibility, which leads to cost efficiency. It may also contribute to enhancing the supply chain's green...

Researchers have recently developed a model for international supply chains for transferring lots in equal-sized batches, taking environmental concerns into account. This scheme incorporated stochastic behaviour of the exchange rate between the vendor's and buyer's currencies as part of the...

While the basic economic order quantity model has found some practical applications, it makes a number of assumptions which do not reflect most real life inventory systems. This paper proposes an inventory system where the items ordered are capable of growing during the course of the inventory...

We present inventory models to schedule an imperfect manufacturing process where a proportion of the items are defective. The proportion is known; and the production is followed by a 100% inspection. The manufacturer implements a rework strategy to rectify the defective items. Since the rework...
