Accurate situational assessment is key to any decision making especially crucial in military command and control, air traffic control, and complex system decision making. Endsley describes three dependent levels of situational awareness, (1) perception, (2) understanding, and (3) projection. This research is focused on Endsley's second-level situational awareness (understanding) as it applies to service-oriented...
Recent progress in grid computing concept and its allied application technologies has helped us to device an efficient tool for heavy workload management. Concept of this middleware technology supports to build more and more complex application which can process large real time data set. Mobilization of under utilized resources among the needy processes can easily be carried out with distributed grid...
Query optimization in sensor grids have two major challenges: (a) optimizing in a multi-query environment, and (b) continuous re-optimization occurring due to new query registrations and de-queries, i.e. queries being stopped unexpectedly. Addressing this problem continuously on a system-wide basis is an infeasible option. In this work called EstuaryDB, we propose a notion of emergent optimization,...
The idea of using power system models in problem solving and decision analysis is really not new, and is certainly not tied to the use of computers. At some point, all of us have used a modeling approach to make a decision. A typical decision tree is used to identify a strategy most likely to reach a goal. This paper describes two methodologies for finding optimal solutions to budgeting and planning...
