The optimal set of machines for laying an oil pipeline in heaving soils
The article considers the question of the optimal acquisition of construction vehicles during the construction of an oil pipeline to soils exposed to seasonal frost heaving. The authors emphasize the development of a calculation program for finding the optimal complex of construction machines, which is based on the Bellman dynamic programming method. The calculation is presented for each of the six stages of the preparation and clearing of the territory and the laying of pipeline links. Automation of the process of finding the optimal solution made it possible to replace the multiple search of the minimum of the function manually. The calculation is made in conditions of complete certainty. As an optimization criterion, the reduced costs for each stage of the functional process are selected. The authors developed a calculation program in the computer-aided design system Microsoft Excel Visual Basic for Applications.
