F (Arob (i)) Formally, Prob (RTT , Arob ) = maxi∈I min{f (x):x∈F (i)} . The price of robustness Prob (RTT ) of problem RTT is defined as the minimum price of robustness among all the robust algorithms. An algorithm Arob is RTT -optimal if Prob (RTT , Arob ) = Prob (RTT ). A robust solution Π for an instance i of RTT is RTT -optimal if: f (Π) = min {f (Π ) : Π is a feasible solution for RTT }. 3 Pseudo-polynomial Algorithms for Fixed Δ In this section, we give some theoretical results, whose omitted proofs can be found in [14].

In what follows, all the activities times and the delays are expressed in minutes. In order to obtain RTT instances, for each corridor among BrBo, MdMi, BzVr and PzBo, we vary Δ ∈ {1, 2, . . 11} and α ∈ {1, 5, 9, 13, 17}. Moreover, we use two different functions L: the first one is based on the real values obtained by available data; the second one is the constant average function which assigns to each activity the same duration time obtained as the average among all real values of each instance.

Note that, in order to compute all the values w(Tv ) for each v ∈ V , one visit of Tr is sufficient. In the next lemma, we prove that for any instance, there exists a RTT -optimal solution which assigns only slack times of size α. Lemma 1. Given an instance i of RTT , for each solution Π for i, there exists a solution Π for i such that f (Π ) ≤ f (Π) and, for each arc a = (x, y), either Π (y) = Π (x) + L(a) or Π (y) = Π (x) + L(a) + α. Denoted by RTTΔ the problem RTT when the maximal number Δ of affected nodes allowed is fixed a priori, algorithm SAΔ , provided in Figure 1, is RTTΔ optimal for any fixed Δ ≥ 1.
