The optimization problem above admits only one optimum solution where the value
of the objective function is 10, as

δ i =

0 for i ∈ [ 1 .. 20 ] except for δ = δ = 1, and

2 18

μ ω 1 ,θ 1 = μ ω 1 ,θ 2 = μ ω 2 ,θ 3 = μ ω 2 ,θ 4 =

0. It is easy to see that this solution corresponds

ρ

to the preferred repair 1 of Example 4.5.
