Dynamic Inoperability Input-Output Model for Python (DIIMPY)

DIIMPY provides the Demand-Reduction and Recovery Dynamic Inoperability Input-Output Model (DIIM) for interdependent functions as described in the papers:

• Haimes, Y. Y., Horowitz, B. M., Lambert, J. H., Santos, J. R., Lian, C. & Crowther, K. G. (2005). Inoperability input-output model for interdependent infrastructure sectors. I: Theory and methodology. Journal of Infrastructure Systems, 11, 67-79.
