We study a generalisation of sabotage games, a model of dynamic network games introduced by van Benthem [16]. The original definition of the game is inherently finite and therefore does not allow one to model infinite processes. We propose an extension of the sabotage games in which the first player (Runner) traverses an arena with dynamic weights determined by the second player (Saboteur). In ...

In an auction for two heterogeneous goods, we show an “aggregate” reserve price leads to equilibria where bidders bid on one item to sabotage their own bid on the other, and bids are decreasing in valuations over a certain range.

In this paper a tournament between teams (a collective tournament) is analyzed, where each contestant may spend productive e¤ort in order to increase his team’s performance or sabotage the members of the opponent team. It is shown that sabotaging the weaker members of a team always decreases their team’s performance more signi…cantly than sabotaging stronger members does. As a consequence, sabo...

Additive Manufacturing (AM, or 3D printing) is an emerging manufacturing technology with far-reaching implications. AM is increasingly used to produce functional parts, including components for safety-critical systems. However, AM’s unique capabilities and dependence on computerization raise a concern that an AM generated part could be sabotaged by a cyber-physical attack. In this paper, we dem...

The buildings, working personnel, and patients and their relatives may directly or indirectly be affected by the disasters. Here we will discuss evacuation, establishing a field hospital, communication, the role of the media in disasters, and defending against sabotage. The affected individuals should be evacuated and transferred to secure zones safely and rapidly. How the decision for evacuati...
