Implications of capacity expansion under uncertainty and value of information: The near-term energy planning of Japan
Krukanont, Pongsak; Tezuka, Tetsuo - In: Energy 32 (2007) 10, pp. 1809-1824
In this paper, we present the near-term analysis of capacity expansion under various uncertainties from the viewpoints of the decision-making process on the optimal allocation of investment and the value of information. An optimization model based on two-stage stochastic programming was...

State-Level Output Supply and Input Demand Elasticities for Agricultural Commodities
Villezca-Becerra, Pedro A.; Shumway, C. Richard - In: Journal of Agricultural Economics Research, 1
Own- and cross-price production elasticities, estimated in four major agricultural states (California, Iowa, Texas, and Florida), measure the sensitivity to price changes of as many as 25 individual crop and livestock output supplies and six input demands. While most responses were highly...

Fill Rates of Single-Stage and Multistage Supply Systems
Sobel, Matthew J. - In: Manufacturing & Service Operations Management 6 (2004) 1, pp. 41-52
A supply system's fill rate is the fraction of demand that is met from on-hand inventory. This paper presents formulas for the fill rate of periodic review supply systems that use base-stock-level policies. The first part of the paper contains fill-rate formulas for a single-stage system and...

Stock Positioning and Performance Estimation in Serial Production-Transportation Systems
Gallego, Guillermo; Zipkin, Paul - In: Manufacturing & Service Operations Management 1 (1999) 1, pp. 77-88
This paper considers serial production-transportation systems. In recent years, researchers have developed a fairly simple functional equation that characterizes optimal system behavior, under the assumption of constant leadtimes. We show that the equation covers a variety of stochastic-leadtime...

Serial Production/Distribution Systems Under Service Constraints
Boyaci, Tamer; Gallego, Guillermo - In: Manufacturing & Service Operations Management 3 (2001) 1, pp. 43-50
We analyze the problem of minimizing average inventory costs subject to fill-rate type of service-level constraints in serial and assembly production/distribution systems. We propose optimal and heuristic procedures to solve this problem. Our model and solution procedures can be used to manage...

Erratum to Bounds in "Serial Production/Distribution Systems Under Service Constraints"
Boyaci, Tamer; Gallego, Guillermo; Shang, Kevin H.; … - In: Manufacturing & Service Operations Management 5 (2003) 4, pp. 372-374
We noticed an error in the upper bound on the optimal system stock in Boyaci and Gallego (2001). We provide a procedure to compute the correct bound.
