“…For example, when searching for a contact lens it is necessary to move slowly on one's hands and knees, but there is also the option of standing up and walking briskly to a di¤erent location. To take a more serious example, there has been a lot of recent interest (Johnson and Ali, 2012) in the detection of landmines and improvized explosive devices (IEDs). An explosives expert searching for an IED may be able to move from place to place quickly in a vehicle, but in order to detect the IEDs she must get out of her vehicle and move at a slower pace.…”

AbstractA Searcher seeks to …nd a stationary Hider located at some point H (not necessarily a node) on a given network Q. The Searcher can move along the network from a given starting point at unit speed, but to actually …nd the Hider she must pass it while moving at a …xed slower speed (which may depend on the arc). In this 'bimodal search game', the payo¤ is the …rst time the Searcher passes the Hider while moving at her slow speed. This game models the search for a small or well hidden object (e.g., a contact lens, improvised explosive device, predator search for camou ‡aged prey). We de…ne a Bimodal Chinese Postman tour as a tour of minimum time which traverses every point of every arc at least once in the slow mode. For trees and weakly Eulerian networks (networks containing a number of disjoint Eulerian cycles connected in a tree-like fashion) the value of the bimodal search game is =2. For trees, the optimal Hider strategy has full support on the network. This di¤ers from traditional search games, where it is optimal for him to hide only at leaf nodes. We then consider the notion of a lucky Searcher who can also detect the Hider with a positive probability q even when passing him at her fast speed. This paper has particular importance for demining problems.

“…The analysis on CBRNe is on going since very long times, therefore recent crises and diffusion of IED (Improvised Explosive Devices) further increased the studies (Powers, 2001;Ivanova & Sandler, 2006;Wilson, 2007;Coleman et al, 2019). Modeling and Simulation have been used in this framework in order to analyze scenarios not only at physical level, but even operational and also the authors have developed several researches in this sector (Bruzzone et al, 2015;Johnson & Ali, 2015;Ruiz et al, 2016, Longo et al 2019. In similar way, Artificial Intelligence (AI) and Intelligent Agents (IA) have been used for CBRNe Scenarios (Bruzzone & Massei, 2017a;Wilner & Babb, 2021;Regal et al, 2022); while advances in sensor networks and JISR address these topics along last years (Winkler et al, 2012;Antoni et al, 2021).…”

This paper proposes an architecture to deal Strategic Decision Making within Urban Area and Industrial Plants due to Risks related to TIC/TIM (Toxic Industrial Chemical, Toxic Industrial Material) that nowadays represent a major issues in our Society due to their diffusion and potential impact. The problem is addressed by comprehensive models in order to provide an effective support to high level Decision Makers thanks to the use of the innovative architecture proposed, based on Strategic Engineering approach. A case study and related Models and AI Solutions are presented to validate the proposed concepts in a specific case study. It is proposed an innovative architecture where the use of IA (Intelligent Agents) and M&S (Modeling and Simulation) are combined to process Big Data arriving from sensor networks and digital systems and to support decision by evaluating alternative COAs (Courses of Actions) were population, countermeasures as well as potential antagonists are simulated by IA together with physical models of critical phenomena (e.g. hazardous material spills, explosions, contamination, fires).

“…The modeling and simulation of the detection of landmines and improvised explosive devices with multiple automatic target detection loops, as presented in [50], provided an example of a military approaches. In [51], the authors stated that a fully automatic target recognition process still fails to satisfy the operational requirements of minefield detection.…”

This paper presents methods for the modeling and simulation of explosive target placement in terrain spectral images (i.e., real hyperspectral 90-channel VNIR data), considering unexploded ordnances, landmines, and improvised explosive devices. The models used for landmine detection operate at sub-pixel levels. The presented research uses very fine spatial resolutions, 0.945 × 0.945 mm for targets and 1.868 × 1.868 cm for the scene, where the number of target pixels ranges from 52 to 116. While previous research has used the mean spectral value of the target, it is omitted in this paper. The model considers the probability of detection and its confidence intervals, which are derived and used in the analysis of the considered explosive targets. The detection results are better when decreased target endmembers are used to match the scene resolution, rather than using endmembers at the full resolution of the target. Unmanned aerial vehicles, as carriers of snapshot hyperspectral cameras, enable flexible target resolution selection and good area coverage.
