Abstract

Reliability, Availability and Cost Analysis of Large Multi-State Systems with Ageing Components

Basic notions of the system multi-state reliability analysis are introduced. The multi-state series system with degrading components is defined and its exact reliability function is determined. The limit reliability function for large multi-state systems is introduced. An auxiliary theorem on limit reliability function of a large multi-state series system, which is necessary for its approximate reliability evaluation, is presented. On the basis of this auxiliary theorem some corollaries are formulated and proved and then applied to approximate reliability and availability determination of a large multi-state series system. Evaluations are given of a multi-state system reliability function, its mean lifetimes in the state subsets and their standard deviations, mean value and variance of the lifetime up to and the number of exceeding the system reliability critical state and its availability coefficient. The cost analysis of a multi-state series system is performed as well. The results are applied to a large telecommunication network reliability, availability and cost analysis.

Abstract

Analysis of the Influence of Factors Determining Traffic on Undesirable Events

The increasing participation of an automobile as a means of transport causes the increase of traffic flow. The insufficient development of road infrastructure, maladjustment to the increasing number of vehicles, and the problem that drivers do not adjust to conditions existing in the system contribute to the low level of traffic safety. The attention has been given to factors that characterize the vehicle, the user and the environment. The example of assessment of the factors' influence on the safety level has been made on the basis of the obtained nonlinear, multiple regression models.

Safety Evaluation of Ship's Maneuvers Carried Out on the Basis of Integrated Navigation Systems (INS) Indications

In the safety evaluation of maneuvers carried out on the basis of INS indications, the real ship's dimensions are used to determine navigation safety level. The paper presents a new approach to this problem. The ship's maneuvering area and collision probability were calculated incorporating uncertainty areas of ship's plan geometry at given probability level for typical configuration of navigational equipment applied in existing pilot systems. The widening coefficients of safety factors for each configuration set were determined and discussed.

Abstract

Contribution to Availability Assessment of Complex Systems with one Shot Items

As we use complex systems with one shot items in many technical applications we need to know basic characteristics of such a system. Performance, safety and others are as much important as dependability measures. As the one shot item is supposed to back up the main system function the total reliability of the system should be higher then. The paper will present a theoretical approach to determining the complex system task/mission success probability rather than a theoretical approach to determining the dynamic reliability (operational availability), and then a practical example.

Abstract

Differences and Mutual Connections of the Transport Safety Systems

Each day in the world's transport system there are more than 3 thousand fatalities; most of them die in road accidents. From the point of view of the safety management, each of the branch systems is organized differently. The differences concern data bases, institutions managing the transport infrastructure and studying the accidents, systems monitoring the traffic of vehicles, trains and ships. Despite many differences in the functioning of particular branches of transport, there are potentially big possibilities of improving the safety systems through integration activities and utilization of good local and foreign experiences in the whole transport sector.

On the basis of this auxiliary theorem some corollaries are formulated and proved and then applied to approximate reliability and availability determination of a large multi-state series system. Evaluations are given of a multi-state system reliability function, its mean lifetimes in the state subsets and their standard deviations, mean value and variance of the lifetime up to and the number of exceeding the system reliability critical state and its availability coefficient. The cost analysis of a multi-state series system is performed as well. The results are applied to a large telecommunication network reliability, availability and cost analysis.

Abstract

Analysis of the Influence of Factors Determining Traffic on Undesirable Events

The increasing participation of an automobile as a means of transport causes the increase of traffic flow. The insufficient development of road infrastructure, maladjustment to the increasing number of vehicles, and the problem that drivers do not adjust to conditions existing in the system contribute to the low level of traffic safety. The attention has been given to factors that characterize the vehicle, the user and the environment. The example of assessment of the factors' influence on the safety level has been made on the basis of the obtained nonlinear, multiple regression models.

Abstract

Safety Evaluation of Ship's Maneuvers Carried Out on the Basis of Integrated Navigation Systems (INS) Indications

In the safety evaluation of maneuvers carried out on the basis of INS indications, the real ship's dimensions are used to determine navigation safety level. The paper presents a new approach to this problem. The ship's maneuvering area and collision probability were calculated incorporating uncertainty areas of ship's plan geometry at given probability level for typical configuration of navigational equipment applied in existing pilot systems. The widening coefficients of safety factors for each configuration set were determined and discussed.

Abstract

Contribution to Availability Assessment of Complex Systems with one Shot Items

As we use complex systems with one shot items in many technical applications we need to know basic characteristics of such a system. Performance, safety and others are as much important as dependability measures. As the one shot item is supposed to back up the main system function the total reliability of the system should be higher then. The paper will present a theoretical approach to determining the complex system task/mission success probability rather than a theoretical approach to determining the dynamic reliability (operational availability), and then a practical example.

Abstract

Proposal of a Method to Evaluate Safety of the Road Transport Systems Operation

The transport system are sociotechnical systems in which the direct realization of the tasks is dealt with by an executive subsystem consisting of the elementary subsystems of a human - a technical object (an operator - a means of transport) type realizing the tasks within the system environment. In respect of a human located within a transport system the most significant criterion in the evaluation of the transports being realized is their safety.

Due to the complexity of the systems being analysed in the paper, it has been attempted to evaluate the influence of the forcing factors on the safety of this system operation.

Damage Hazard Model for Chosen Element of the Aircraft Structure Taking Into Account Fatigue Crack Development Stages

The subject of the present paper is the modeling of aircraft structure fatigue processes which endanger flight safety. It is assumed that the simple course of the process of aircraft structure elements fatigue encompasses the following stages: initiation of cracks, crack development to the limit value, destruction of the element of structure. These stages can be taken as random incidents or random processes. The paper provides a description of the two initial stages as random processes. The relations obtained allow to define the reliability of the structure element and to evaluate the damage hazard in given time period.

Abstract

Differences and Mutual Connections of the Transport Safety Systems

Each day in the world's transport system there are more than 3 thousand fatalities; most of them die in road accidents. From the point of view of the safety management, each of the branch systems is organized differently. The differences concern data bases, institutions managing the transport infrastructure and studying the accidents, systems monitoring the traffic of vehicles, trains and ships. Despite many differences in the functioning of particular branches of transport, there are potentially big possibilities of improving the safety systems through integration activities and utilization of good local and foreign experiences in the whole transport sector.
