Opis:

There are presented general safety analytical models of complex multistate technical systems related to their operation processes. They are the integrated general models of complex technical systems, linking their multistate safety models and their operation processes models and considering variable at the different operation states safety structures and their components safety parameters. The conditional safety functions at the system particular operation states and independent of the system particular operation states the unconditional safety function and the risk function of the complex technical systems are defined. These joint models of the safety and the variable in time system operation processes are constructed for multistate series, parallel, “m out of n”, consecutive “m out of n: F”, series-parallel, parallel-series, series-“m out of k”, “mi out of li”-series, series-consecutive “m out of k: F” and consecutive “mi out of li: F”-series systems. The joint models are applied to determining safety characteristics of these systems related to their varying in time safety structures and their components safety characteristics. Under the assumption that the considered systems are exponential, the unconditional safety functions of these systems are determined. The proposed models and methods are applied to the safety analysis, evaluation and prediction of the one subsystem of the port grain transportation system related to varying in time their operation processes, structures and components safety parameters.

Opis:

A new approach is proposed for safety investigations of complex multistate systems. These systems have dependent components, called critical infrastructures, with variable operating conditions. The safety function of the critical infrastructure system is defined and determined for an exemplary “m out of l” critical infrastructure. In the fully-developed model, it is assumed that system components have multistate exponential safety functions with interdependent departure rates from subsets of safety states. A critical infrastructure safety model is adopted for an oil pipeline transportation system operating in a maritime port.

Opis:

In the paper, there are presented the methods for identification of the critical infrastructure operation process on the basis of statistical data coming from this process realizations related to the critical infrastructure operating environment threats. These are the methods and procedures for estimating the unknown basic parameters of the critical infrastructure operation process semi-Markov model and identifying the distributions of the critical infrastructure operation process conditional critical infrastructure operation process sojourn times at the particular operation states. There are given the formulae estimating the probabilities of the critical infrastructure operation process straying at the particular operation states at the initial moment, the probabilities of the critical infrastructure operation process transitions between the operation states. Moreover, there are given formulae for the estimator of unknown parameters of the distributions suitable and typical for the description of the critical infrastructure operation process conditional sojourn times at the operation states. Namely, the parameters of the uniform distribution, the triangular distribution, the double trapezium distribution, the quasi-trapezium distribution, the exponential distribution, the Weibull’s distribution and the chimney distribution are estimated using the statistical methods such as the method of moments and the maximum likelihood method. The chi-square goodness-of-fit test is described and proposed to be applied to verifying the hypotheses about these distributions choice validity. The procedure of statistical data sets uniformity analysis based on Kolmogorov-Smirnov test is proposed to be applied to the empirical conditional sojourn times at the operation states coming from different realizations of the same critical infrastructure operation process.

Opis:

The main aim of the paper is to define the operation and climate change influence on the safety of a critical infrastructure considered as a complex system in its operating environment. As the result, a general safety analytical model of a complex technical system under the influence of the operation process related to climateweather change process is proposed. Further, the conditional safety functions at the operation process related to climate-weather change process, the unconditional safety function and the risk function of the complex system at changing in time operation and climate-weather conditions are defined. Moreover, the mean lifetime up to the exceeding a critical safety state, the moment when the risk function value exceeds the acceptable safety level, the intensities of ageing of the critical infrastructure and its components and the coefficients of the operation and climate-weather impact on the critical infrastructure and its components intensities of ageing are proposed as the other significant safety indices for any critical infrastructure.

Opis:

The main aim of this paper is to present the general safety analytical models of complex multistate technical systems related to their operation processes including operating environment threats. In the case of critical infrastructure, the determination of its safety function and its risk function, which graph corresponds to the fragility curve are defined. Moreover, its mean lifetime up to the exceeding a critical safety state and the moment when its risk function value exceeds the acceptable safety level and the critical infrastructure and its components intensities of degradation and the coefficients of operation process including operating environment threats influence on the critical infrastructure and its components intensities of degradation are introduced as the other significant safety indicators. The proposed models are given for multistate series, parallel, “m out of n”, consecutive “m out of n: F”, series-parallel, parallel-series, series-“m out of k”, “mi out of li”-series, seriesconsecutive “m out of k: F” and consecutive “mi out of li”: F”-series systems.

Opis:

The paper is concerned with an application of the critical infrastructure operation process related to climate-weather change model to identification and prediction of this process for maritime ferry. There are distinguished four different processes for the corresponding ferry operating area. Further, using identified parameters of the ferry operation process and the ferry operating area climate-weather change processes, there are determined the unknown parameters of those processes. Namely, there are determined the probabilities of the processes staying at the initial states, the probabilities of the transitions between the states and the mean values of the processes' conditional sojourn times at particular states. Finally, there are predicted the main characteristics of the ferry operation process related to climate-weather change processes at the distinguished operating area.
