Manufacturers and wholesalers are increasingly cost conscious in response to today’s hyper-competitive environment. Lateral transshipment (LT) has been proposed as a viable solution to drive total inventory costs down whilst increasing customer service level. Our study proposes five LT decision rules with a case-based roadmap to guide professional inventory management. Results of this large fas...

We consider a supply chain, which consists of N retailers and one supplier. The retailers may be coordinated through replenishment strategies and lateral transshipments, that is, movement of a product among the locations at the same echelon level. Transshipment quantities may be limited, however, due to the physical constraints of the transportation media or due to the reluctance of retailers t...

Despite the fact that there is a large body of literature on Production Routing Problem (PRP), we were struck by dearth research outsource planning and lateral transshipment. This paper presents mixed-integer linear programming model for incorporating outsourcing, transshipment, back ordering, lost sales, time windows into production routing problems. Then robust optimization will be introduced...

Transshipment, the sharing of inventory among parties at the same echelon level of a supply chain, can be used to reduce costs. The effectiveness of transshipment is in part determined by the configuration of the transshipment network. We introduce chain configurations in transshipment settings, where every party is linked in one connected loop. Under simplifying assumptions we show analyticall...

This paper is based on observations that competing retailers have the option of either agreeing in advance to transship excess inventory to each other or seeing unsatisfied customers switch to the competitor for a substitute. A transshipment game and a substitution game between competing retailers is studied. After establishing the existence and uniqueness of a pure-strategy Nash Equilibrium in...
