Journal ArticleDOI
An intermediate input model of dairy production using complex survey data
Rolf Färe,Gerald Whittaker +1 more
TL;DR: It is found that the decomposition of production into subproduction processes reduces the dimensions of problem specification, with the effect that a larger number of variables may be usefully included in the model.
Journal ArticleDOI
Optimization-based trade-off analysis of biodiesel crop production for managing an agricultural catchment
TL;DR: Biophysical trade-offs among bioenergy crop production based on rape seed, food crop production, water quantity, and water quality in the Parthe catchment in Central Germany are analyzed and Pareto optimal frontiers among multiple objectives are estimated.
Journal ArticleDOI
Directional output distance functions: endogenous directions based on exogenous normalization constraints
TL;DR: In this article, the authors developed a method for estimating directional output distance functions with endogenously determined direction vectors based on exogenous normalization constraints, which is reminiscent of the Russell measure proposed by Fare and Lovell (J Econ Theory 19:150-162, 1978).
Journal ArticleDOI
Automatic Calibration of Hydrologic Models With Multi-Objective Evolutionary Algorithm and Pareto Optimization
TL;DR: This study investigated the application of multi‐objective evolutionary algorithm (MOEA) and Pareto ordering optimization in the automatic calibration of the Soil and Water Assessment Tool (SWAT), a process‐based, semi‐distributed, and continuous hydrologic model.
Journal ArticleDOI
A hybrid genetic algorithm for multiobjective problems with activity analysis-based local search
Gerald Whittaker,Remegio Confesor,Stephen M. Griffith,Rolf Färe,Shawna Grosskopf,Jeffrey J. Steiner,George W. Mueller-Warrant,Gary M. Banowetz +7 more
TL;DR: The objective of this research was the development of a method that integrated an activity analysis model of profits from production with a biophysical model, and included the capacity for optimization over multiple objectives.
