Hi,
I am trying to translate this MIP problem - LINDO problem (below) into
MathProg.
It is timber harvesting scheduling MIP problem. I did convert LINDO LP
Strategic Forest Estate model to MathProg model. This is a new area
for me - mixed integer programming model for operational planning.
One area bothering me is the declaration of the binary variable in MIP problem.
For example, the variable,
###
var Harvest { s in STAND, p in PERIOD}, default 0;
####
Now the binary variable, how do I define it?
####
var xxxxx {s in STAND, p in PERIOD} binary;
#####
What would be the xxxx?
This var xxxx binary is for Period 1 only, as you see it in the model
below. How this "var Harvest" and "var xxxx" would be link to each
other?
I have difficulty converting this LINDO MIP model into CPLEX MIP model
as well. How do you convert this LINDO MIP model into CPLEX MIP model?
Thanks.
Regards, Noli
