Integrated Lot Sizing in Serial Supply Chains with Production Capacities

Hoesel, Stan van; Romeijn, H. Edwin; Morales, Dolores Romero - In: Management Science 51 (2005) 11, pp. 1706-1719

We consider a model for a serial supply chain in which production, inventory, and transportation decisions are … integrated in the presence of production capacities and concave cost functions. The model we study generalizes the uncapacitated … serial single-item multilevel economic lot-sizing model by adding stationary production capacities at the manufacturer level …

A Dynamic Lot-Sizing Model with Demand Time Windows

Lee, Chung-Yee; Çetinkaya, Sila; Wagelmans, Albert P. M. - In: Management Science 47 (2001) 10, pp. 1384-1395

One of the basic assumptions of the classical dynamic lot-sizing model is that the aggregate demand of a given period must be satisfied in that period. Under this assumption, if backlogging is not allowed, then the demand of a given period cannot be delivered earlier or later than the period. If...

Price competition, free entry, and welfare in congested markets

Melo, Emerson - In: Games and Economic Behavior 83 (2014) C, pp. 53-72

In this paper we study the problem of price competition and free entry in congested markets. In particular, we consider a network with multiple origins and a common destination node, where each link is owned by a firm that sets prices in order to maximize profits, whereas users want to minimize...

The Role of Heuristic Methods as a Decision-Making Tool in Aggregate Production Planning

Ridha, Mahmood B. - In: International Journal of Business Administration 6 (2015) 2, pp. 68-76

This study aims to explain the role of heuristic methods in the decision making process and as a tool for knowledge capture. As a result, we conclude that heuristic methods give better support to the decision maker than mathematical models in many cases especially when time and cost are critical...

An O(Tˆ3) algorithm for the capacitated lot sizing problem with minimum order quantities

Okhrin, Irena; Richter, Knut - Wirtschaftswissenschaftliche Fakultät, … - 2010

This paper explores a single-item capacitated lot sizing problem with minimum order quantity, which plays the role of minor set-up cost. We work out the necessary and suffcient solvability conditions and apply the general dynamic programming technique to develop an O(T³) exact algorithm that is...

Optimal Commodity Trading with a Capacitated Storage Asset

Secomandi, Nicola - In: Management Science 56 (2010) 3, pp. 449-467

This paper considers the so-called warehouse problem with both space and injection/withdrawal capacity limits. This is a foundational problem in the merchant management of assets for the storage of commodities, such as energy sources and natural resources. When the commodity spot price evolves...
