This paper defines and studies the multi-terminal maximum-flow network-interdiction problem (MTNIP) in which a network user attempts to maximize flow in a network among K P 3 pre-specified node groups while an interdictor uses limited resources to interdict network arcs to minimize this maximum flow. The paper proposes an exact (MTNIP-E) and an approximating model (MPNIM) to solve this NP-hard ...

Abstract: This paper proposes a reliable network interdiction model with multiple unit costs, which maximizes the minimum arrival cost of the invader to the sink by setting obstacles on some arcs with limited resources in the given network. In other words, given a graph with a source and a sink, several arcs will be selected with limited resources such that each path contains as many weights as...

In this article, we elaborate on a budget constrained extension of the r -interdiction median problem with fortification (RIMF). The objective in the RIMF is to find the optimal allocation of protection resources to a given service system consisting of p facilities so that the disruptive effects of r possible attacks to the system are minimized. The defender of the system needs to fortify q fac...

The topic of this chapter is the application of a matheuristic to the leaderfollower type of games—also called static Stackelberg games—that occur in the context of discrete location theory. The players of the game are a system planner (the leader) and an attacker (the follower). The decisions of the former are related to locating/relocating facilities as well as protecting some of those to pro...

The ‘Black Lives Matter’ (BLM) movement in 2020 exemplifies efforts to counter prejudices and the colourist narrative. Harmful use of topical skin lightening agents continues worldwide despite interdiction or restricted under domestic, European international regulations. Commentary. Narrative review. In this Short Communication, we consider significance societal perspectives colour, glocalized ...

Network segmentation of a power grid's communication system can make the grid more resilient to cyberattacks. We develop novel trilevel programming model optimally segment system, taking into account actions an information technology (IT) administrator, attacker, and operator. The IT administrator is allowed existing networks, attacker given budget inflict damage on by attacking segmented syste...
