From: Rethinking infrastructure design from component failure to systemic resilience

The model consists of thousands of simultaneous equations. The overall structure of the model can be summarized in five major blocks: (1) Output and Demand, (2) Labor and Capital Demand, (3) Population and Labor Supply, (4) Compensation, Prices, and Costs, and (5) Market Shares. This Figure shows the blocks and their relationships.
