A knowledge-based system for robustness analysis of large-scale economic systems

The paper gives a conceptual framework for robustness analysis of large-scale economic systems, and its realization through interactive computer-aided software. The mismatch between the economic system and the corresponding mathematical model is discussed. The computer-aided system combines algorithmic and expert system techniques. An important feature of the present system is the modularization of the software package which allows a distributed problem solving approach. A fourth-order macroeconomic model, with typical parameters, which demonstrates the margin of power of the governmental body can exercise on the various sectoral activities, is used to illustrate some of the concepts presented in this paper.
