Opis:: In the paper the environment and infrastructure influence of the ground ship-rope transporter operating in Naval Shipyard in Gdynia on its operation processes is considered. The results are presented on the basis of a general model of technical systems operation processes related to their environment and infrastructure. The transporter operation process is described and its statistical identification is given. Next, the reliability, risk and availability evaluation of the transporter in variable operation conditions is presented. In addition, the reliability and availability basic characteristics of the system assuming its components’ failure dependence are determined. Finally, the obtained results for the ground ship-rope transporter under the assumption that its components are dependent and independent are compared.

Opis:: In the paper the safety function of a multistate series network with dependent assets, with dependent subnetworks and with dependent assets of its subnetworks is determined. The multistate series-parallel network with dependent assets of its subnetworks and multistate series-“m out of k” network with dependent assets of its subnetworks is considered. Further the multistate parallel and “m out of n” networks with dependent assets are analyzed. The safety function of multistate parallel-series and “m out of l”-series networks with dependent assets of its subnetworks, and finally of multistate parallel-series and “m out of l”-series networks with dependent subnetworks and dependent assets of these subnetworks are determined. Proposed theoretical models of dependency are applied to the safety analysis of the exemplary electricity network. Finally, the obtained results are compared with results for the considered electricity network without assumption about dependencies between assets and subnetworks.

Tematy:: safety

load sharing model
Opis:: This report focuses on the safety analysis in the multistate ageing system after changing the safety state by any of its components, the inside interactions among the remaining components may cause the change of those components’ safety states. As we consider multistate systems, in a local, equal and mixed load sharing model of dependencies. For them, we analyze the safety of a multistate parallel-series and “m out of l”-series system, assuming that the lifetimes of subsystem components in the safety state subset are decreasing according to the local load sharing rule and the lifetimes of subsystems are decreasing according to the equal load sharing rule.

Opis:: In the paper there is presented the computer program for reliability analysis of complex technical systems with reserved and improved components along with computer program description and application. The computer program allows for automatic reliability characteristics prediction of the improved complex technical systems with hot and cold single reservation of their components and of the improved complex technical systems with reduced intensities of departure from the reliability state subsets of their components. Under the assumption that system components have exponential reliability functions, the unconditional reliability function, the mean values and standard deviations of the unconditional lifetimes in the reliability state subsets and in particular reliability states, the system risk function and the moment when the system risk exceeds a permitted level of the complex technical systems before and after their improvement are determined.

Opis:: In the paper an approach to the reliability analysis of multistate series systems assuming their components dependency according to the local load sharing rule is presented. There is introduced the local load sharing model of components dependency (of departures from the reliability states subsets) and the reliability function of a multistate series system with dependent components is determined. These results are also presented in case system components have exponential reliability functions and in this case basic reliability characteristics are given.

Tematy:: critical infrastructure

simulation
Opis:: Critical Infrastructure (CI) Preparedness and Resilience modelling, simulation & analysis (MS&A) is a major issue in CI protection (CIP) and crisis management. This is due to the rapid growth of the inference of the smart complex systems in the modern society activities. The concept of resilience in CIP is not yet clearly defined. However, “resilience” is often used as a measure of the system good behaviour facing a given threat. Under a given threat, a CI may evolve within a set of well-defined operating phases. Subsequently, the failure of the CI to provide the expected service will depend not only on the threat nature but also on the operating phase. A tentative probabilistic model is proposed describing the robustness and the resilience of a well-defined infrastructure facing a given threat.
