摘要：The shut-off valves are an important element to the safe operation of a trunk oil pipeline. Actual problem of shut-off valves optimal placing on trunk oil pipeline is defined with respect to minimal oil spill during accidents and planning repair operations. The method of optimal placing is presented as a problem of nonlinear mathematical programming with limits and these limits are minimal distance between line valves. The solution of mathematical programming problem is given with the help of rigorous (alternance) parametric optimization method which is founded on special qualities ultimate solution. The approach of shut-off valves placing on three and four linear block valves taking into account typical cases. The results of optimal linear block valves placing calculation are shown at a site of trunk oil pipeline 77 km long. As a result of the application of the proposed technique, a reduction of the maximum volume of oil spill on the linear part of the oil trunk pipeline by 25 percent or a reduction in the number of shut-off valves from four to three for the initial value of the maximum oil spill can be achieve.
