In a rapidly changing environment, the behavior and decision-making power of agents may have to be adaptive with respect to a fluctuating autonomy. In this paper, a centralized fuzzy approach is proposed to sense changes in environmental conditions and translate them to changes in agent autonomy. A distributed coalition formation scheme is then applied to allow agents in the new autonomy to renegotiate to establish schedule consistency. The proposed framework is applied to a real-time logistics control of a military hazardous material storage facility under peace-to-war transition.

We consider a container terminal discharging and uploading containers to and from ships. The discharged containers are stored at prespecified storage locations in the terminal yard. Containers are moved between the ship area and the yard using a fleet of vehicles, each of which can carry one container at a time. The problem is to dispatch vehicles to the containers so as to minimize the total time it takes to serve a ship, which is the total time it takes to discharge all containers from the ship and upload new containers onto the ship. We develop easily implementable heuristic algorithms …
Quantifying Vulnerability To Critical Infrastructure, Barry Charles Ezell
Quantifying Vulnerability To Critical Infrastructure, Barry Charles Ezell
Engineering Management & Systems Engineering Theses & Dissertations
Military and civilian leaders have the responsibility to protect our Nation's critical infrastructure, communities, and symbols of American power from terrorists, home and abroad, as well as from natural disasters. To this end, assessments are conducted to reduce vulnerability. The literature offers multiple definitions of vulnerability and measurement has not been adequately addressed. Thus, the purpose of this research has been to develop and deploy a systems-based model that quantifies vulnerability to critical infrastructure. This research defines critical infrastructure vulnerability as a measure of the susceptibility of critical infrastructure to threat scenarios. Vulnerability is a function of (1) threat scenario, …
Modeling And Analysis Of Clandestine Networks, Clinton R. Clark
Modeling And Analysis Of Clandestine Networks, Clinton R. Clark
Theses and Dissertations
Since Sept. 11, 2001, there has been great interest in the military and intelligence communities in using Social Network Analysis (SNA) to support the disruption and destruction of global terrorist networks. SNA results, however, tend to be descriptive and are limited due to the lack of advantageous properties of the relationship measures applied to the arcs in a social network. Further, SNA techniques generally focus on a single network context while real relationships are based in multiple contexts. This thesis develops a new proxy measure of pair-wise potential influence between members of a network, a Holistic Interpersonal Influence Measure (HIIM). …
Modeling Of Commercial Maritime Port Recoverability From Security Disruptions: Work-In-Progress, C. Ariel Pinto, Wayne K. Talley
Modeling Of Commercial Maritime Port Recoverability From Security Disruptions: Work-In-Progress, C. Ariel Pinto, Wayne K. Talley
Engineering Management & Systems Engineering Faculty Publications
This article describes active research in commercial maritime port's recovery from security disruptions which explores the synergy of economic and simulation models in investigating the recoverability of ports after security incidents. Previous study has identified decision variables and throughput simulation models of port operation. However, none of these models have been utilized to investigate port's recovery from a security disruption and in evaluating recoverability investments. The method of research includes analysis of recorded disruptions, identification of impediments to recovery and investment criteria for recoverability. This article provides managers insight into including security and continuity of operation in managing various types …
