The objective of this project is to study problems with partial         information arising in situations involving computer communications from        the point of view of systems and control theory.  The main case of              interest is that of distributed database systems.  This research focuses        on a study of concurrency control and recovery protection against aborts        and crashes as control problems for discrete event systems.  These              problems are characterized by the issue of partial information, with            communication playing a central role.  The goal of the project is to            investigate the appropriateness of state models for posing questions of         control and communication and for formulating and analyzing proposed            solutions.  In particular, a study will be made of the applicability of         the theory of Ramadge and Wonham for supervisory control of discrete            event systems to these problems.  This work should contribute to a better       understanding of control and system-theoretic issues in discrete event          systems.
