Subject: | [Help-glpk] Indexing a subset from 1..n |
Date: | Wed, 28 Nov 2012 08:15:46 +1100 |
Hello all,
I have a set of Periods from which I create the subset OpenPeriods when the facility is open. param nPeriods; set Periods, default{1.. nPeriods}; param FacilityOpen{p in Periods}, binary; set OpenPeriods:= setof{p in Periods: FacilityOpen[p] = 1} (p); The facility is not open during all periods and I have a constraint that considers the configuration of the facility the previous time it was open. So I am trying to index the set of OpenPeriods from 1...card(OpenPeriods) rather than with p but so far without any luck. Any help would be much appreciated. Thanks, Joel |
