Feasibility study of logging road elements plan
The peculiarities of the research work are stated and the need for its further development is shown. Taking into account the structural links and limitations of the system, a mathematical model of the feasibility study of the total reduced costs of the route plan, the longitudinal profile and the width of the carriageway was compiled, which has a various amount of construction and operating costs reduced to the initial year in a predetermined search area. The objective function is determined, which is the main part of the mathematical model including all the elements and connections of the feasibility study of the timber haul roads elements. It is concluded that the search for the optimal combination of geometric elements and the timing of their change is an extreme task, and the best method for solving it is to determine the state of the system corresponding to the minimum value of the objective function, which is the sum of construction and operating costs reduced to the initial year.
