Integrated Modeling Systems

This reprint examines in some detail the concept of an integrated modeling system. It distinguishes three main types of integration model integration, solver integration, and integration of various utilities. Model integration is further divided into four subtypes based on a four-level model abstraction hierarchy specific models, model classes, modeling paradigms, and modeling traditions. The paper then goes on to consider how structured modeling supports the various types of integration. The overall conclusion is that structured modeling offers an attractive approach to the design of integrated modeling systems. Reprints. KR
