PMP (Ward method) applied to agricultural systems
Posted: Fri Nov 19, 2021 10:35 am
Hi everyone!
I'm trying to calibrate a PMP model trough the Ward Method but I can't. I would liketo represent the irrigated crop pattern of an irrigated area in Southern Italy.
The equation system is characterized by: GM maximization subject to LAND constraint, WATER constraint and LABOUR constraint.
The model roughly calibrate without LABOUR constraint but when I add it the model tell me:
Iter Phase Ninf Infeasibility RGmax NSB Step InItr MX OK
0 0 1.5115316315E+06 (Input point)
** An equation is inconsistent with other equations in the
pre-triangular part of the model.
I attached the the model at the end of this message.
Anyone has any suggestion?
Thank you so much
Laura
