Optimization of livestock feed blend by use of goal programming

Abstract

This paper presents a model for determining an optimal blend of ingredients for livestock feed by application of goal programming. Besides the standard problem of livestock feed where the requirements for basic nutrients have to be met at minimized costs and which is solved mainly by linear programming, the authors also introduce the goals of meal quality where different requirements of decision makers are modeled by goal programming. © 2010 Elsevier B.V.
