Organizational modelling and problem solving using object-oriented knowledge representation server and visual language

Object-oriented knowledge representation systems allow an organization to be modeled in an understandable way. User interaction with such a system is enhanced if the graphic representations normally used, such as organization charts and room layout plans, are supported through visual languages directly generating the underlying knowledge structures. The operational and problem-solving procedures of an organization expressed visually within this framework become overt and accessible, and their implementation and consequences can be automated and evaluated. This paper reports some experience in the design and implementation of a lightweight, objectoriented knowledge representation server, and its application to organizational modeling and problem solving. The primary user interface is through a formal visual language implemented as a drawing environment on graphic workstations. The open architecture implementation of the server allows it to be integrated with existing applications, such as corporate database and accounting systems, and also allows functionality to be added through self-contained modules requiring no changes in the kernel system.
