Abstract : The research performed under this Contract has been concerned with a number of topics within the general area of decision, estimation and control for systems operating in an environment of uncertainty. Of special interest have been decentralized decision and control problems that arise typically in connection with large-scale systems, and in particular with Naval Command Control and Communications systems. Included here have been our development of decentralized shortest path algorithms for networks, our examination of decentralized sequential detection and decision-making problems, and out studies of quantitative measures of interaction between system inputs and outputs (or between subsystems) and the implications of these for near disturbance localization and near decoupling and for estimation and control problems. Among the other problems examined are the use of the cutoff rate as a criterion for signal design in coded, direct-detection optical communication, a unified treatment of nonlinear smoothing problems with a variety of state and observation models, and the design of a minimum-order observer that estimates a prescribed multi-dimensional linear function of the system state.
