Subscripts matrix addition
Posted: Mon May 03, 2010 3:59 pm
I am developing a model (my firts one out of class) related to farm management. One of its modules involves 5 different crops and 6 different patches where they are grown, some overlapping patches. They will further integrate with soil quality module, herd structure and development, feed production, etc. and finally with effects of Conservation Agriculture practices (that are different per crop) in all these variables.
I have created some subscripts to deal with their equations, but I am having a difficulty with one of them. I am attaching that part of the model.
I want to have a variable "Cop Area" that summarizes the sum of each individual crop allocated area, and then put that together with the production variables of yields to have each one total production, and not dealing with each individual area and then each individual production as it does now.
I am not being able to create that summarized area matrix . I have tried inumerous equations, always with some errors in the result. I present two of them in the attached model.
Thanks for any help,
Lellis
