Algorithm 1 Which city has better services towards enhancing QoL?

read X = first city, Y = second city, E = Service under comparison; read N = total number of indicators under E, S = total number of E in the comparison; set I = indicator under investigation, Type = core OR supportive,    IVx = indicator value of first city, set IVy = indicator value of second city, CVi = (comparison value of indicator i) = 0, RVe = (resulted value of service E) = 0, n = 0, s = 0; while s < S do   for each E in S do    while n < N do     for each I in E do       compare IVx AND IVy     if IVx > IVy AND Type = core then          set CVi = +2;     else if  IVx < IVy AND Type = core then          set CVi = −2;           else if IVx > IVy AND Type = supportive then          set CVi = +1;     else if  IVx < IVy AND Type = supportive then          set CVi = −1;            else // IVx = Ivy                     set CVi = 0;     end for     n++;     RVe+ = CVi;    end while    if RVe > 0 then            X is better than Y in E    else if RVe < 0 then        X is worse than Y in E    else            X AND Y are equally in E   end for   s++;   RV+ = RVe; end while    if RV > 0 then            X is better than Y in this case    else if V < 0 then        X is worse than Y in this case       else            X AND Y are equally in this case
