Organization of planning in transport construction

Abstract

Purpose. Development of methods and models of economic efficiency of the integrated use of various modes of transport in the interests of ensuring national security of the state. Methods. System analysis, logical-mathematical modeling, systems theory, economic-visual modeling, research methods of operations, economic and mathematical methods. Results. The paper discusses the need for the application of economic and mathematical models in the design of transport construction (model of “moving the earth masses”, linear programming model, design of the “red line” on the longitudinal profile, dynamic programming model). Conclusion. The difficult stage of the transition of economic and mathematical analysis from the verbal description of the system process to the elemental base of the mathematical apparatus. Most research models of operations are designed for single criteria. Economic and mathematical modeling allows the effect of “private optimization”.

Methodology for economic substantiation of assessment of the integrated use of organizational and technological solutions for land allocation for road and bridge construction

“…In the theory of the efficiency of any system, one of the main problems is modeling the criteria for efficiency. With regard to the assessment of organizational and technological solutions for land allocation for road and bridge construction, it is recommended to use three concepts: performance indicators, performance criteria and limitations [16][17][18][19][20]. Such a gradation of indicators will provide the opportunity to:  to form, with the help of limitations, a lot of competitive options in the choice and justification of the optimal technology for land allocation for road and bridge construction;  choose the most effective of them using the criteria.…”
