I want to assign each D13 as a max of the three terms. 

D13(i,j,a,t)  = max {  (D3(r,i,t) - D3(r,i ,t+traveltime[i][j][t])) / omerga[r], (D4(e, i,t) - D4(e ,i ,t+traveltime[i][j][t])) / varepsilon[e],   0}

I was trying to use the following link but could not figure out. https://www.ibm.com/developerworks/community/forums/html/topic?id=a3c8515c-9a51-425a-8f4f-010cb3b73c1c

Would you mind helping me out?
