Abstract : All social systems must deal with the problem of integrating what's actually happening with what they believe should be happening. A standard system for expressing general common-sense knowledge for inclusion in a general database...McCarthy is needed for the effective application of expert systems to this task. This project investigated whether a Knowledge Dictionary System (KDS) based on State of Affairs (SA) Ossorio can achieve this result. The investigation was performed with respect to the reference problem of managing the knowledge necessary to perform and analyze complex scheduling. The conclusion reached was that a KDS knowledge base could be implemented as a set of database relations that capture the part-whole characteristics of schedules; and that a small set of second order relational operators, principally closure, could be combined to achieve a complete part-whole inference logic for supporting fragmentary scheduling at any level and complex dependencies within and across levels including what if analyses. Keywords: Expert systems, Artificial intelligence, Database scheduling, Project management, Knowledge base.
