Optimal lot sizing for deteriorating items with triangle-shaped demand and uncertain lead time

Hsu, Ping-Hui; Teng, Hui-Ming; Wee, Hui-Ming - In: European Journal of Industrial Engineering 3 (2009) 3, pp. 247-260

The ordering policy for retailers and the suppliers' system are influenced by lead time and deterioration. In this study, we consider deteriorating items with triangle-shaped demand and uncertain lead time. The triangle-shaped demand has the characteristic of increasing demand during the...

The Value of Component Commonality in a Dynamic Inventory System with Lead Times

Song, Jing-Sheng; Zhao, Yao - In: Manufacturing & Service Operations Management 11 (2009) 3, pp. 493-508

primarily on single-period models or periodic-review models with zero lead times. In this paper, we consider a continuous …-review system with positive lead times. We find that although component commonality is in general beneficial, its value depends … strongly on component costs, lead times, and dynamic allocation rules. Under certain conditions, several previous findings …

Note--Optimal Component Acquisition for a Single-Product, Single-Demand Assemble-to-Order Problem with Expediting

Fu, Ke; Hsu, Vernon N.; Lee, Chung-Yee - In: Manufacturing & Service Operations Management 11 (2009) 2, pp. 229-236

We consider a component acquisition problem for a contract manufacturer who faces a one-time stochastic demand for a single product consisting of a number of components. Components can be ordered early at normal prices before the demand is revealed, or they can be replenished later at higher...
