    Transportation problem with degressively stepped costs

  • Original language description

    The transportation problem belongs to one of elementary decision problems we can meet in practice. The problem can be solved with linear programming methods. In specialized literature, we can find many possible modifications of the transportation problem which have been formulated and solved on the basis of many real situations. This fact reveals its broad area of possible applicability. The article deals with a modification of the transportation problem; the modification consists in a specific nonlinear form of the objective function which has not been found in literature. In the article, it is considered that a carrier offers a lower carriage to a customer if a certain (minimum) number of goods is transported. Such type of the transportation problem has already been considered in the past but the objective criterion has been assumed to be continuous nonlinear. In our modification nonlinearity of the objective criterion is discontinuous (stepped) and is decreasing (the carriage per unit is decreasing with the increasing number of transported goods). The task can be solved as balanced (the total supply and the total demand are equal) or unbalanced (the total supply and the total demand are not equal). A linear mixed integer mathematical model which models the modification of the transportation problem is presented in the article. To test the model and to find a dependence of the calculation time on input data some calculation experiments are presented in the article. The calculation experiments are carried out using optimisation software Xpress – IVE.
