Optimal air defense strategies for naval task group

Karasakal, Orhan
We develop solution methods for the air defense problem of a naval task group in this dissertation. We consider two interdependent problems. The first problem is the optimal allocation of a set of defensive missile systems of a naval task group to a set of attacking air targets. We call this problem the Missile Allocation Problem (MAP). The second problem called the Sector Allocation Problem (SAP) is the determination of a robust air defense formation for a naval task group by locating ships in predefined sectors on the surface. For MAP, we present three different mixed integer programming formulations. MAP by its nature requires real time solution. We propose efficient heuristic solution procedures that satisfy the demanding time requirement of MAP. We also develop mathematical programming models for SAP. Proposed branch and bound solution scheme for SAP yields highly satisfactory solutions. We characterize the interaction between MAP and SAP and develop an integrated solution approach.


Anti-Ship Missile Defense for a Naval Task Group
Karasakal, Orhan; Özdemirel, Nur Evin; KANDİLLER, LEVENT (Wiley, 2011-04-01)
In this study, we present a new formulation for the air defense problem of warships in a naval task group and propose a solution method. We define the missile allocation problem (MAP) as the optimal allocation of a set of surface-to-air missiles (SAMs) of a naval task group to a set of attacking air targets. MAP is a new treatment of an emerging problem fostered by the rapid increase in the capabilities of anti-ship missiles (ASMs), the different levels of air defense capabilities of the warships against th...
A multi-objective approach for dynamic missile allocation using artificial neural networks for time sensitive decisions
Karasakal, Orhan; Karasakal, Esra; Silav, Ahmet (2021-01-01)
In this study, we develop a new solution approach for the dynamic missile allocation problem of a naval task group (TG). The approach considers the rescheduling of the surface-to-air missiles (SAMs), where a set of them have already been scheduled to a set of attacking anti-ship missiles (ASMs). The initial schedule is mostly inexecutable due to disruptions such as neutralization of a target ASM, detecting a new ASM, and breakdown of a SAM system. To handle the dynamic disruptions while keeping efficiency h...
Precision measurement of the structure of the CMS inner tracking system using nuclear interactions
Sirunyan, A. M.; et. al. (IOP Publishing, 2018-10-01)
The structure of the CMS inner tracking system has been studied using nuclear interactions of hadrons striking its material. Data from proton-proton collisions at a center-of-mass energy of 13 TeV recorded in 2015 at the LHC are used to reconstruct millions of secondary vertices from these nuclear interactions. Precise positions of the beam pipe and the inner tracking system elements, such as the pixel detector support tube, and barrel pixel detector inner shield and support rails, are determined using thes...
Undesirable and semi-desirable facility location problems
Nadirler, Deniz; Karasakal, Esra; Department of Industrial Engineering (2004)
In this thesis, single undesirable and semi-desirable facility location problems are analyzed in a continuous planar region considering the interaction between the facility and the existing demand points. In both problems, the distance between the facility and the demand points is measured with the rectilinear metric. The aim in the first part where the location of a pure undesirable facility is considered, is to maximize the distance of the facility from the closest demand point. In the second part, where ...
Multiresolution analysis of S&P500 time series
KILIC, Deniz Kenan; Uğur, Ömür (2018-01-01)
Time series analysis is an essential research area for those who are dealing with scientific and engineering problems. The main objective, in general, is to understand the underlying characteristics of selected time series by using the time as well as the frequency domain analysis. Then one can make a prediction for desired system to forecast ahead from the past observations. Time series modeling, frequency domain and some other descriptive statistical data analyses are the primary subjects of this study: i...
