  • The modeling of logging timber freights by combine transport network

    his paper presents mathematic model of logging timber freights by combine transport network. This model optimize of cargo-carrying and technological roading of forest bases in timber procurement enterprise and lumber factories. Authors developed procedures and functions, which allowed solving optimization of cargo-carrying and technological roading of forest bases in timber procurement enterprise and lumber factories. Authors also analyze technological process on cut-over land, loading bay and railheads. This reporting allows to reduce transport costs and makes optimal schedule of logging timber freights.
