Decision Support for Effects Based Operations
Abstract
The tasks in this research are motivated by an effort to integrate temporal and spatial aspects of a large-scale discrete event system (DES) for dynamic control (i.e., planning and re-planning) purposes. As stated under Task 2, the dynamic planning and re-planning problems require satisfaction of two types of constraints, namely temporal and spatial, and the challenge here is to integrate both these constraints in a single analytical formulation of the problem. In addition, the constraints may not be all quantitatively specified; therefore, there is a further need to have pro-visions for both quantitative and qualitative constraint-handling in this formulation. The results, achieved so far, have successfully solved some of the issues and pose both challenges and promise in resolving others. The dynamic control of Discrete-Event Systems (DES) often requires revising a produced temporal model during and/or after system specification phase, e.g., the constraints or system/mission requirements may change during or before a plan's execution. The approach developed in this research Zaidi and Raul 2002 uses a multi-layered Point Graph (PC) structure to keep the input specifications in the lowest layer of a PC.
