The First Achievement of a Given Level by a Random Process
P. 3820–3825.
Semakov S., Semakov A., Semakov I.
We estimate the probability that the first achievement of a given level by the component y_1(x) of n-dimensional continuous process y(x)={y_1(x),…,y_n(x)} occurs at some moment x* from a given interval (x′,x′′) and, at this moment x*, the condition (y_2(x*),…,y_n(x*))∈D holds, where D is a given domain of (n−1)-dimensional Euclidean space R^(n−1). The need to calculate the abovementioned probability arises in the problems of aircraft control during landing.

This paper considers the problem of estimating the probability of the following event: a continuous random process will first reach a given level at some time from a given variation interval of the independent variable. The general results obtained previously are specified for a smooth Gaussian process. The estimates are calculated for different values of ...

We propose the method for calculating the probability of a safe landing for ship-based aircraft. We define a safe landing as the event that the initial touch of the landing surface by an aircraft occurs on a given segment of the deck, and at the time of this contact, the phase coordinates of the aircraft ...

The behavior of any real system is a process to a greater or lesser degree probabilistic. As a rule, it is impossible to specify exactly which external influences and internal mechanisms of interaction of the system components will be decisive in the future. As a consequence, we cannot accurately predict the behavior of the system. ...

We propose a scheme for finding the probabilities of events related to crossings of a level by a random process. Using this scheme, we estimate the probability that the first achievement of a given level by the component y_1(x) of an n-dimensional continuous process y(x)={y_1(x),…,y_n(x)} occurs at some moment x* from a given interval (x′,x′′) and, at this moment x* , the other components y_2(x*),…,y_n(x*) satisfy given ...

We consider the problem of the exit of a diffusion Markov process to the boundary of a given domain. We concentrate on the one-dimensional case and solve the problem of finding the probability that the first exit of the process beyond the established corridor will occur at a given time. We apply the obtained results ...

New goodness-of-fit tests for Rayleigh distribution family with an arbitrary scale-parameter σ, are constructed on the base of some property and some characterization. For these tests, limiting distributions are described, local Bahadur efficiencies under close alternatives are calculated, and asymptotic comparison of our test statistics is performed. ...

We study random domino tilings of a multiply-connected domain with a height function defined on the universal covering space of the domain. We prove a large deviation principle for the height function in two asymptotic regimes. The first regime covers all domino tilings of the domain. We also prove a law of large numbers for ...

Transportation is a key logistics function, which determines the dynamic nature of material flows in logistics
systems. At the same time, transportation is a source of uncertainty of logistics operations performance in the supply chain.Obviously, the development of a new approach for evaluation of the duration of delivery “Just-In-Time” (JIT) will improve the efficiency of supply chains ...
