The primary goal of the Zeus design is to define reliable object management functions for distributed command and control systems and to evaluate the performance and the correctness of the recovery mechanisms for these functions.

The model and program development system substantially enhances the capabilities of automating the development process of current graphically-oriented systems. The enhancement includes representations of virtual devices in the model formulation process and use of graphically specified programs as the user visible representation of an executable simulation model.

Programs that allow users to create and manipulate attributed directed graphs on graphics workstations have therefore become common. However, the programming effort required to produce such applications is significant and usually involves interaction with a complex graphics package. We present an Extended Directed Graph Editor, EDGE, that provides application programmers with an object-oriented editor for generic directed graphs. This editor may be used as a rapid prototyping tool and customized to obtain high-quality graphical front-ends without interacting with a general-purpose graphics package.
