METHOD OF CORRELATION MODELING OF BREAKING CONNECTION OF CRITICAL COMPONENTS OF AN ELEVATOR FOR A DEEP WELL IN CONDITIONS OF INCOMPLETE INFORMATION Russian patent published in 2020 - IPC G06F30/17 G06F30/20 

FIELD: data processing.

SUBSTANCE: invention discloses a method of correlation modeling of breaking connection of critical components of an elevator for a deep well in conditions of incomplete information. Data on faults of critical components of the elevator are collected in various states of violation and statistics are collected, which relates to statistical information on moments of random response at each state of violation in conditions of incomplete information. Functions of marginal probability distribution for each condition of violation are obtained by using method of function approximation. Attributes of probabilistic correlation between each pair of states of violation are analyzed by using the criterion of conformity and determination of the most suitable functions of copula for description of various attributes of correlation of violation in part. A hybrid copula function model is created by combining the marginal probability distribution function for each disturbance state with each most suitable copula function.

EFFECT: technical result consists in improvement of accuracy of simulation of joint probability of multiple conditions of elevator failure for deep well.
