This paper analyzes the problem of profit optimization known in literature for a random variable with an increasing function of increasing failure rate. The problem is ge [...]

The paper examines a 3-state system of preventive replacements. It was shown that the system availability for which failure time has distribution only slightly different [...]

The developed mathematical model is to allow to diagnose the state of fitness of individual vehicle brake friction nodes in real time In this work, it is assumed that the [...]

This paper analyzes reliability of paper machine. Probability distributions for repair time and worthiness time for paper machine and its main subsystems are examined. Th [...]

This paper analyzes the application of the semi-Markov process to the construction of a 4-state system of preventive replacements with minimal repair. Asymptotic availabi [...]

The paper presents the description of algorithm for calculation characteristics of simulation model for the operation process realized at the transport system. The model [...]

One of the methods for an assessment of the system ability to perform its task properly is to establish the risk connected with the transport means functioning. The prese [...]

This paper presents a policy of preventive replacement that consists of the burn-in procedure and age-replacement. Criteria function in the derived maintenance model is a [...]

This study presents the problems connected with control of operation and technical objects maintenance systems. In particular, it discusses assessment and control of the [...]

In this paper we propose a mixture of two different normal distributions to model heterogeneous of rail vehicles parameters. Maximum likelihood estimations of the paramet [...]
