Post-disaster relief distribution under road vulnerabilities and aftershocks

Baksı, Bikem Bennu
In this thesis, a two-stage stochastic mixed integer programming approach is proposed to determine the two types of post-disaster decisions, namely relief distribution with direct/ lateral transshipment and emergency roadway repair simultaneously, under the risk of potential aftershocks. Two objective functions are considered: minimization of the demand-weighted total travel time subject to satisfying all demand (efficacy-based), and minimizing the maximum unsatisfied demand over all demand points (equity-based). A case study for a potential earthquake in Istanbul, Turkey is implemented, through which it is shown that (i) ignoring the potential effects of aftershocks may lead to detrimental results, (ii) without road repair, relief transportation is significantly hampered, (iii) the decisions are quite robust to the number of roads that are affected by the disaster, and (iv) lateral transshipment leads to improvements in transportation times to a certain extent.
