Masson, Paul R. - International Monetary Fund (IMF) - 2000

The “hollowing-out,” or “two poles” hypothesis is tested in the context of a Markov chain model of exchange rate transitions. In particular, two versions of the hypothesis—that hard pegs are an absorbing state, or that fixes and floats form a closed set, with no transitions to...

Optimal solution for a cargo revenue management problem with allotment and spot arrivals

Moussawi-Haidar, Lama - In: Transportation Research Part E: Logistics and … 72 (2014) C, pp. 173-191

We consider a single-leg cargo revenue management problem, in which a two-dimensional cargo capacity is sold through allotment contracts and in the spot market. Capacity sold on an allotment basis is guaranteed. We optimally solve the problem of determining how much of the total weight and...

Managing an assemble-to-order system with after sales market for components

Elhafsi, Mohsen; Hamouda, Essia - In: European Journal of Operational Research 242 (2015) 3, pp. 828-841

In this paper, we consider an assemble-to-order manufacturing system producing a single end product, assembled from n components, and serving an after sales market for individual components. Components are produced in a make-to-stock fashion, one unit at a time, on independent production...

Capacitated Multi-Item Inventory Systems with Random and Seasonally Fluctuating Demands: Implications for Postponement Strategies

Aviv, Yossi; Federgruen, Awi - In: Management Science 47 (2001) 4, pp. 512-531

We address multi-item inventory systems with random and seasonally fluctuating, and possibly correlated, demands. The items are produced in two stages, each with its own lead-time; in the first stage a common intermediate product is manufactured. The production volumes in the first stage are...

A Periodic Review Inventory Model with Demand Influenced by Promotion Decisions

Cheng, Feng; Sethi, Suresh P. - In: Management Science 45 (1999) 11, pp. 1510-1523

In this paper, we use a Markov decision process (MDP) to model the joint inventory-promotion decision problem. The state variable of the MDP represents the demand state brought about by changing environmental factors as well as promotion decisions. The demand state in a period determines the...

Inventory control in a lost-sales setting with information about supply lead times

Bendre, Abhijit Bhagwan; Nielsen, Lars Relund - In: International Journal of Production Economics 142 (2013) 2, pp. 324-331

Supply chain collaboration using advancements in information technology is on the rise and this includes sharing of information between suppliers and buyers. In this paper we study the value of information about the development of supply lead times from a buyer's perspective. We consider a...
