The goal programming model proves to be a useful procedure in
determining the optimal livestock feed blend.In a relatively simple
way the decision maker is allowed to introduce into the model a
number of additional requirements that are easily reformulated
into mathematical form relatively easily leading to new output
results. The paper shows how a standard multi-criteria problem is
transformed into a goal programming model in the form of
weighted and lexicographic goal programming,leaving open the
issue of adequate weighing of single elements in the goal function
and deviation variables.
The developed model can be successfully used in solving similar
problems in practice that are dependent on several criteria,e.g.feed
blend for another kind of livestock of a diet plan for a larger group of
people (hospitals,canteens,etc.)
