Building efficient product portfolios at John Deere and Company.(OR PRACTICE)
July 1, 2007... John Deere & Company (Deere), one of the world's leading producers of machinery, manufactures products composed of various features, within which a customer may select one of a number of possible options. On any given Deere product line, there may be tens of thousands of combinations of...

Incentives and commonality in a decentralized multiproduct assembly system.
July 1, 2007... In this paper, we explore the impact of decentralized decision making on the behavior of multiproduct assembly systems. Specifically, we consider a system where three components (two product specific and one common) are used to produce two end products to satisfy stochastic customer demands....

Dynamic bid prices in revenue management.
July 1, 2007... We formally derive the standard deterministic linear program (LP) for bid-price control by making an affine functional approximation to the optimal dynamic programming value function. This affine functional approximation gives rise to a new LP that yields tighter bounds than the standard LP....

Two-stage robust network flow and design under demand uncertainty.
July 1, 2007... We describe a two-stage robust optimization approach for solving network flow and design problems with uncertain demand. In two-stage network optimization, one defers a subset of the flow decisions until after the realization of the uncertain demand. Availability of such a recourse action...

Optimal control of serial inventory systems with fixed replenishment intervals.
July 1, 2007... We consider a single-item, periodic-review, serial inventory/production system, with linear inventory-holding and penalty costs. To facilitate shipment consolidation and capacity planning, we assume that the system has implemented fixed replenishment intervals; each stage is allowed to order...
