Game Theory Application in Security and Sustainability
http://teamcore.usc.edu/papers/2011/ADT11_cameraReady.pdf
National security and sustainability is more recent arena for the application of game theory. As discussed in the link above, the LAX airport for instance started using security games to help randomize their security patrols in just 2007. In these two critical fields there are many uses for games to help predict human behavior. Which is key to stopping a threat from damaging or homeland. The most recent developments in security games are the attempts to make an algorithm that represents human decision making almost perfectly. To do people are complying many different games together, which hopefully can predict adversaries actions as close as possible. This paper discusses mostly anti terrorism applications of security games. Another area in which the security is ran by an algorithm is the TSA security systems. For example they have IRIS (Intelligent Randomization In Scheduling) which is solely for the deployment of air marshals on planes with the largest risk of being attacked. Furthermore they use GUARDS (Game-theoretic Unpredictable and Randomly Deployed Security) what makes this security game different than all its predecessors it that it accounts for many different security activities at the same time and it controls hundreds of employees at a time. GUARDS algorithm is built mainly by the use of the Stackelberg game, and is being tested currently in unknown airports. There are issues with created games that will serve as our security one that caught my eye is the “Scalability Challenge” which focuses on the sheer number of available outcomes. The following except represents just how many different outcomes there can be, “Real-world problems, like the FAMS security resource allocation problem, present trillions of action choices for the defender in security games. Such large problem instances cannot even be represented in modern computers, let alone solved using previous techniques”. (USC.edu page 8)
Sustainability is looked at through game theory framework that focuses on utilizing energy in the most efficient ways possible, this is done using multivariate games that represent human behavior. It discusses the different ways buildings can manage their energy usage, whether it be manual, reactive control, or proactive control, or proactive control with some simply games applied as well. In each scenario energy is used differently, which means there is one that is most efficient, while meeting the needs of the employees.
Both in maximizing security and energy usage simply game theory is applied to create a new way of operating off limited resources. By utilizing games like the “attacker and defender game” which we used for soccer in class. People are able to create more complex security games which protect our airports everyday. Another building block to these more complex security games is the Best Response usage we have been discussing with our elementary games. As we continue to improve mirroring human behavior through game theoretic framework, we will constantly be providing a safer world.
