Representation of Activity Knowledge for Project Management.
Abstract
Representation of activity knowledge is important to any application which must reason about activities, such as new product management, factory scheduling, robot control, vehicle control, software engineering and air traffic control. This article provides an integration of the underlying theories needed for modeling activities. Using the domain of large computer design projects as example, the semantics of activity modeling is described. While past research in Knowledge Representation has discovered most of the underlying concepts, our attempt is towards their integration. This includes the epistemological concepts for erecting the required knowledge structure; the concepts of Activity, State, Goal and Manifestation for the adequate description of the plan and the progress; and the concepts of Time and Causality to infer the progression among the activities. We also address the issues which arise due to the integration of aggregation, time and causality among activities and states.
