Heterogeneous travelling repairmen problem with time windows (hetTRPTW) is customer oriented problem with large possibilities for practical applications in logistics area. Models and algorithms developed for solving one problem with a cumulative objective function may be, with a little effort, transformed for solving similar problem with a cumulative function. In that sense, aim of this paper is to present results obtained by implementing an algorithm developed for solving cumulative capacitated vehicle routing problem in solving hetTRPTW.
