Abstract
The use of statistical methods to determine the quality of the construction of trunk pipelines in the regions of the Far North
Incoming article date: 29.04.2021The theme of the work is dedicated to the problem of quality assessment of constructing of a linear part of the main pipeline in the extreme north. Constructing of objects in permafrost areas is related to extra activity about maintenance of efficiency of the pipeline system. Extra difficulty while constructing of a linear part of the main pipeline is caused by tougher requirements for regulatory documentation to the work performed. These facts colour quality assessment of the object to be constructed. The task is developing a method of the quality assessment of construction and installation works that responds to the parameters of data collecting speed and calculation simplicity. During the developing of the a method of the quality assessment of a linear part of the main pipeline the method of analytical hierarchy process was used, for getting the nomenclature of the most important jobs from the perspective of the safety of the object. Methods in mathematical statistics was used for processing of the results of the measurement made. Hypothesis testing method allowed receiving the confidence interval for the sample of random variables. Practical benefit of the work is obtaining the method of the quality assessment, which allows to make conclusions about the quality of objects constructing using publicly available data on the work process.
