Opis:: Small scale mining continues to contribute significantly to the growth of Ghana's economy. However, the sector poses serious dangers to human health and the environment. Ground failures resulting from poorly supported stopes have led to injuries and fatalities in recent times. Dust and fumes from drilling and blasting of ore present health threats due to poor ventilation. Four prominent small scale underground mines were studied to identify the safety issues associated with small scale underground mining in Ghana. It is recognized that small scale underground mining in Ghana is inundated with unsafe acts and conditions including stope collapse, improper choice of working tools, absence of personal protective equipment and land degradation. Inadequate monitoring of the operations and lack of regulatory enforcement by the Minerals Commission of Ghana are major contributing factors to the environmental, safety and national security issues of the operations.

Opis:: First, basic notions of the multistate system safety analysis are introduced, i.e. the multistate components and the multistate system, the multistate system component safety function, the multistate system safety and the multistate system risk function are defined. Moreover, the multistate system component and the multistate system main safety characteristics, i.e. their mean values of the lifetimes and in the safety state subsets and in the particular safety states and standard deviations and the moment when the system risk function exceeds a fixed permitted level are determined. Furthermore, there are constructed safety models of the multi-state homogeneous and non-homogeneous series, parallel, “m out of n”, consecutive “m out of n: F”, series-parallel, parallel-series, series-“m out of n”, “m out of n”-series, series-consecutive “m out of n: F” and consecutive “m out of n: F”-series systems and their safety functions are determined. Moreover, a very often met in practiceseries system composed of multistate subsystems identical with the considered earlier multistate systems is considered and its safety function is determined.

Opis:: The general model of a complex system changing its safety structure, its components safety parameters and its operation cost during the variable operation process and linear programming are applied to optimize the system operation process in order to get the system operation cost optimal values. The optimization problem allowing to find the optimal values of the transient probabilities of the complex system operation process at the particular operation states that minimize the system unconditional operation cost mean value in the safety states subset not worse than a critical system safety state under the assumption that the system conditional operation cost mean values in this safety state subset at the particular operation states are fixed is presented. Further, the procedure of finding the optimal values operation cost is presented and applied to the exemplary complex technical system.

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:: A multi-state approach to defining basic notions of the system safety analysis is proposed. A system safety function and a system risk function are defined. A basic safety structure of a multi-state series system of components with degrading safety states is defined. For this system the multi-state safety function is determined. The proposed approach is applied to the evaluation of a safety function, a risk function and other safety characteristics of a ship system composed of a number of subsystems having an essential influence on the ship safety. Further, a semi-Markov process for the considered system operation modelling is applied. The paper also offers a general approach to the solution of a practically important problem of linking the multi-state system safety model and its operation process model. Finally, the proposed general approach is applied to the preliminary evaluation of a safety function, a risk function and other safety characteristics of a ship system with varying in time its structure and safety characteristics of the subsystems it is composed of.

Opis:: Railway transport is one of processes controlled with a certain level of risk. It is apparent that due to a limited level of our knowledge, the technical level and limited funds we cannot count on absolute safety (zero risk) but we must admit that in a real technical system some error or fault may occur and its occurrence may mean a certain risk for the controlled process. The authors focus on proposing and presenting potentially usable measures that could increase the safety of traffic operation at the level crossings operated by the ŽSR (Slovak Railways). Technical and organizational measures are discussed separately. Some of proposed measures are specific for Slovak conditions only, however, to a certain extent some findings can be generalized and possibly applied in other countries, too.

Opis:: The main objective of this paper is to present recently developed, the general safety analytical models of complex multistate technical systems related to their operation processes and to apply them practically to critical infrastructures. To realize this goal, the integrated model of critical infrastructure safety related to its operation process is proposed. The basic safety characteristics of this model are presented as the very practically significant. Furthermore, the unconditional safety functions of systems with different safety structures are determined under assumption that their safety functions are exponential. In case of the critical infrastructure safety analysis, its safety function and risk function which graph corresponds to the fragility curve, its mean lifetime up to the exceeding a critical safety state, the moment when its risk function value exceeds the acceptable safety level, the component and critical infrastructure intensities of ageing/degradation and the coefficients of operation impact on component and critical infrastructure intensities of ageing are defined.

Opis:: The subject and main purpose of this study is to develop risk analytic model for the design and operation of water supply sector. A water supply system belongs to the critical infrastructure of cities, and it should be a priority task for waterworks and even for the local authorities to ensure the suitable level of its safety. A water supply systems (WSS) ought to be high reliable continuous operating system. Failure factors in WSS should be identified and prioritized, for example, the causing factors in the most frequent failures in waterpipe network. Drinking water supply utilities are responsible for providing a safe and reliable supply of potable water to their customers. Risk priority helps asset manager to target and refine maintenance plans, capital expenditure plans, investigative activities, and deal with potential failure before it occurs. In this paper, we present a review of classic risk analyses, risk management and new methodology for water supply networks management. This paper presents a framework for the analysis of performance risk in water supply that can be applied to the entire system or to individual subsystems. It is expecting that the methodology for the water supply performance risk analysis would provide the city leadership for decision making support.

Opis:: The current state of mobility in our cities is still showing worse and worse transport, security and environmental conditions. The most common problem of traffic services in cities is the inability to arrange the conditions for the transport of persons and the transport of goods and services. Inappropriate conditions are evident mainly in traffic congestion, which cause significant time losses for all users of the means of transport (mass transport of persons is not exemption). The daily practice proves that one of the crucial conditions not only for the satisfaction of the inhabitants, but also for the city’s own functionality is the high-quality, fast, safe and dynamic transport and also parking on its territory. Increasing and widespread traffic collapse in cities is caused by two factors. The first is an enormous increase in car traffic which significantly limiting other types of transport. The second is an inappropriate localization of various activities and facilities. Unregulated urban development is caused by disregarding the landuse plan and cities have unregulated construction. This results in inadequate traffic requirements in specific areas, which significantly exceed the capacities of transport communications. In our papers are described mentioned problems and, as a deterrent example, we introduce the city of Žilina.
