Hi,
I am running a model in which I have a Boolean decision variable of 2 dimension: d1[wards][TS].

Wards-> Total 200

TS-> Transfer Stations (Total 200)

As of current declaration all 200X200 decision variables are getting stored and declared.
I also have distance between each wards and TSs. And I want to delete/ not to be stored those decision variables for which the corresponding distance is more than 10 km.

I am using interactive optimizer. Please help me out with this.
Thanks in advance. 

Hi,

you could have a look at

IDE and OPL > Optimization Programming Language (OPL) > Language User's Manual > Introduction to OPL > Modeling tips > Sparsity

If you use tuple set instead of arrays you ll be able to reduce memory footprint
