Design process and decision rationale models for the N-Chime interface system

Abstract

The N-CHIME interface system was designed with the broad objective of enabling, or "empowering," different types of users to carry out effective modeling and simulation applications with the Hierarchical Simulation Language ( HSL ). A design methodology was developed that is based on a "parallel processes" model: a triad of parallel design processes, one directed at each of the user, the interface, and the application. For comprehensive and systematic interface design, such a methodology is essential. N-CHIME has been implemented and tested. This paper presents an overview of the design models and some of the resulting tools and techniques supportive of the application-specific user. It also highlights the importance of providing online access to the design decision rationales that were used for the various user-visible tools and devices.
