The obtained optimal solution does not completely satisfy the
decision maker,because this diet plan has not used two important
ingredients x5 (fish meal)and x7 (soya hulls).Two additional
constraints are therefore introduced allowing these two ingredients to be represented by at least 2% (x5Z0.02, x7Z0.02). The
obtained result is finally completely satisfactory for the decision
maker and it is shown in the last column of the Table 6. In this
scenario the quantity of protein is by 5.3831 higher than in the
minimal requirements i.e. it amounts to 19.5381(Table 7).
