The purpose of this study is to test empirically for the first time the general hypothesis that inventory to sales ratios have decreased over time in the German economy. Although inventory reduction has been a prevalent topic in the production and operations management literature, there is a...

This paper investigates the issue of channel coordination for a two echelon supply chain consisting of one manufacturer and one retailer. In this supply chain, the demand is sensitive to promotional efforts/sales teams׳ initiatives. A production-inventory model is developed that considers the...

The pharmaceutical, biotechnology and life sciences industry was worth approximately US$1 trillion in 2010, of which 73.2% was attributed to pharmaceuticals, 25% to biotechnology and the remainder to life sciences. Regenerative medicines, which use live cells to cure previously incurable...

The present paper proposes a mathematical model and a solution approach to the Stochastic Capacity Planning and Dynamic Network Design Problem. Here, strategic decisions usually comprise developing the necessary capacity — through either incrementing capacity on existing assets (facilities or...

This paper introduces a new motivation for information sharing in decentralized supply chains—as a mechanism to achieve truthful information sharing and to reduce signaling costs. We study a two-echelon supply chain with one manufacturer selling a homogenous product to n price-setting...

The principal challenge of inventory control in supply chains is that the interacting autonomous enterprises have to plan their production and logistics under information asymmetry, driven by different, often conflicting objectives. In this paper, four different computational approaches are...

A simulation optimization framework is proposed for supply chain inventory management of highly perishable products. A new replenishment policy based on old inventory ratio is developed, hence called OIR policy. It is an age-based policy using only partial age information to measure the...

Academic and business fields have frequently examined the significance and influence of collaborative development interactions and feedback mechanisms for supply chain value innovation. Value co-creation and value constellations, which serve as innovation drivers in channel integration, are...

In a recent paper, Hoque (2011) developed two single-vendor multi-buyer models with synchronization by transferring the vendor′s lot with equal and/or unequal sized batches. He reported that his proposed models lead to significant cost reductions when compared to the existing related ones in...

This paper considers a two-echelon supply chain model with a single vendor and two buyers in which the vendor supplies the same item to both buyers at a finite production rate. The purpose of this study is twofold. First, mathematical models are developed for the integrated vendor-managed...
