Methodology for determining the reliability integral indicator of cargo placement and fastening methods

Abstract

   Ensuring the reliability of cargo placement and fastening methods remains an urgent task in the field of transportation process safety. Currently, the reliability of the loading method at the development stage is assessed according to disconnected criteria that do not give a comprehensive idea of the risk level of its use. The purpose of the article is to develop a methodology for calculating the integral indicator characterizing the reliability of the method of placing and securing cargo at the stage of development and approval.
   The research was carried out on the basis of an analysis of the methodology of the calculation justification of the methods of placing and securing goods. The analysis and generalization of information, the main indicators contained in the loading schemes were carried out. The method of calculating the integral indicator characterizing the reliability of the method of placing and securing cargo at the stage of development and approval is presented. The article describes in detail the first three, most important, stages of the methodology.
    The categories of indicators characterizing the reliability of cargo placement and fastening methods and reflected in the design and explanatory notes to loading schemes are defined: cargo placement, stability; strength of cargo fasteners; strength of parts and assemblies of rolling stock. The assessment was made on 11 indicators, which are divided into a number of parameters. To normalize the parameters of the indicators, indicators are introduced in the range from 0 to 1. The values of reliability indicators for each category are found as an arithmetic mean.
    The results of the work are aimed at minimizing errors in the development and coordination of loading methods, can be used to automate the process of developing and coordinating methods of placing and securing goods, as well as to increase the effectiveness of measures to improve the reliability of methods of placing and securing goods.
