The Impact of Demand Aggregation Through Delayed Component Allocation in an Assemble-to-Order System
Bernstein, Fernando; DeCroix, Gregory A.; Wang, Yulan - In: Management Science 57 (2011) 6, pp. 1154-1171
We consider an assemble-to-order system in which multiple products are assembled from a common component and a set of product-dedicated components. Component capacities are chosen prior to a finite-horizon selling season, and the common component is allocated to the products based on observed...

Make to Order or Make to Stock: Model and Application
Rajagopalan, S. - In: Management Science 48 (2002) 2, pp. 241-256
Some firms make all their products to order while others make them to stock. There are a number of firms that maintain a middle ground, where some items are made to stock and others are made to order. This paper was motivated by a consumer product company faced with the decision about which...

A model for heuristic coordination of real life distribution inventory systems with lumpy demand
Berling, Peter; Marklund, Johan - In: European Journal of Operational Research 230 (2013) 3, pp. 515-526
This paper presents an approximation model for optimizing reorder points in one-warehouse N-retailer inventory systems subject to highly variable lumpy demand. The motivation for this work stems from close cooperation with a supply chain management software company, Syncron International, and...

Priority Scheduling Rules for Repairable Inventory Systems
Hausman, Warren H.; Scudder, Gary D. - In: Management Science 28 (1982) 11, pp. 1215-1232
Improved priority scheduling rules are presented for a repair shop supporting a multi-item repairable inventory system with a hierarchical product structure. A variety of scheduling rules are evaluated using a simulation of a representative shop and product structure. The results indicate that...

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...

Management of Supply Chain: X-to-order Concepts vs Make-to-stock Model
Mihiotis A. - In: International Journal of Business Administration 5 (2014) 3, pp. 30-33
In a challenging market, companies¡¯ ability to act faster is considered a basic advantage. From a value chain aspect, when a company cannot change its internal production processes and the external supply streams according to the demand requirements, this may lead to sales reduction or stock...
