How can I make this set?

Hi, let s be a index of scenario and j index of Network Nodes.(s={1*200} , j={1*100}) d(s,j)= total impacts of contamination scenario s, if the contaminant is first detected by scenario at j. W(s)=the subset of Network Nodes which d(s,j)<>0. W'(s)= the subset of W(s) such that d(s,j)<>d(s,j') , for ...
