Hi, I'm trying to schedule personnel depending upon attributes. Per person I have multiple vectors:
< id, attr_1, attr_2, attr_3, .., attr_n> where attr_n is an integer in [0,1]. There are various vectors to model the various combinations of attributes that the person might fulfill. e.g.: 1, 0, 0, 0, 1 1, 0, 0, 1, 1 would describe a person with id 1 that can either supply attribute 4 or attribute (3 and 4). a timeslot has a vector that describes the needed attribute, i.e.: <1, 1, 2, 1> : 1 * attr1, 1 * attr2, 2*attr3, 1*attr3 I created a matrix with all people and their attributes: 1, 0, 0, 0, 1 1, 0, 0, 1, 1 2, 1, 1, 0, 0 What I want now is to create subsets of the people-matrix with a distinct contraint for the first column (so that a person can only be assigned once) and another constraint that states that sum(column_(i+1)) >= timeslot_i. The constraints wouldn't be the problem but I'm out in the dark how to create the subset :( Is this an usable approach to the problem? I tried to find some introduction documents to gecode but so far failed.
