Hi,
In the glpk
distribution there are examples of two dimensional model objects, such
as
param a{i in I, j in
J}, >= 0;
to model, say,
geographical coordinates. These structures are initialised in the data
section using code such as:
param a
: 1 2 3 4 5 :=
1 12 15 12 10 11
2 23
25 19 11 15
3 15 40 21 75
8
4 9 2 9 32
31
5 15 18 19 10 11;
However, if we
define a structure with more than two dimensions, such
as
param a{i in
I, j in J, k in K}, >= 0;
to represent,
say, the amount of resource capacity k at coordinate i, j, then how do you
initialise the structure in the data section of the mod file? This is not
clear to me from the documentation supplied with the
distribution.
Thank you for
any help.
