Opis:
The article aims to present practical methods for prioritising the activities of maintenance departments based on the Pareto analysis and the failure risk analysis. Based on the collected data on the number of observed failures and their removal times, commonly known reliability indicators were determined, which were then used to estimate the probabilities and consequences of failures in terms of the risk of loss of production continuity. Based on commonly collected failure data, the developed methods allow proposing to the maintenance departments the sequence of maintenance and repair work to be undertaken in terms of minimising the risk of failure. Risk analysis is somewhat commonly used in the practice of maintenance departments (e.g. RBI, FMEA, ETA, FTE, HIRA). The added value of this work is the use of reliability indicators for estimating the values of risk components, i.e., probability and consequences. The method was developed on the basis of operational data collected in one of the plants of the dairy cooperative and, after assessing the effects of its implementation, it was implemented in other enterprises of the cooperative.

Opis:
The paper is concerned with the developments of risk analysis during the last decade, starting from full range quantitative risk analysis of e.g. a level crossing based on the CENELEC standards EN50126 and EN50129 up to semi-quantitative methods for risk analysis. To expedite this shift from pure quantitative approaches to a more categorized approach were the perennial challenges of insufficient availability of accurate data and the sheer complexity of the reality to be model quantitatively. The article contains both a presentation of a complete quantitative risk analysis for a level crossing as well as a discussion of the crucial points that will need improvement on the basis of a new semi-quantitative standard for risk analysis that has been issued as a national pre-standard in Germany. The relation to the current regulations stipulated by the European Railway Agency and recent publications on this issue are presented as well.

Opis:
This paper discusses the question of classifying the sea areas as sea areas difficult for navigation, unrestricted sea areas and sea areas restricted by land (bottom or shore). Most of all, the article depicts the characteristics of restricted sea areas. It presents the attempt to define in a new way the following notions: "safety of shipping", "safety of navigation", "risk of navigation", "risk of collisions", "navigational obstacle", and "sea area difficult for navigation". In this paper author also presents methods that can be used for estimating safety of navigation (navigational risk) in the restricted sea areas by means of the model of the ship's domain. The essence of the method suggested in the thesis is the systematic approach to sea vessel operation in the aspect of estimating its safety when navigating in restricted sea areas.

Opis:
Morocco is basically an agricultural country; almost 40% of the workforce is employed in this sector. Xylella fastidiosa is a xylem-inhabiting pathogen which can infect more than 300 plant species, although most host species are symptomless. Until relatively recently, X. fastidiosa was primarily limited to North and South America, but in 2013 a widespread epidemic of olive quick decline syndrome caused by this fastidious pathogen appeared in southeastern Italy, and later several cases of X. fastidiosa outbreaks have been reported in other European countries (France, Germany and Spain). Following these recently confirmed findings of X. fastidiosa in the European Union, this bacterium has become a serious threat to the Moroccan flora. The national phytosanitary authorities have adopted several measures to prevent the introduction of X. fastidiosa into the national territory by deciding, inter alia, to suspend importation of host plant species to the bacterium from infected areas. This paper presents the phytosanitary risk of this bacterium in Morocco.

Opis:
There are different approaches to risk assessment. The SOLAS Convention is the most important safety instruments at maritime transport. The biggest risk is a major navigational incident because it can result in fatalities and pollution. Possibly the major cause of collision incidents is not fully understanding and complying the COLREGS rules. It is not possible to create a simple flowchart to define a suitable approach to risk assessment of a ship. However, some of broad factors can be used to aid the selection of a suitable risk assessment approach in maritime transport. In the literature, we can find many methods and applications for maritime transportation risk analysis. There is a recent focus on foundational issues in risk analysis, especially for intensified research on fundamental concepts and principles. This paper presents the attempt of applying the Bow-Tie methodology at maritime transport. The benefits of using Bow-Tie diagrams for risk assessment have been showed at use, for many of technical systems and processes. This methodology known as barrier diagrams, provide a readily understandable visualization of the relationships between the causes of the failure's event, the escalation of such events to a range of possible outcomes, the controls preventing the event from occurring and the preparedness measures in place to limit the consequences. The Bow-Tie is very useful for structured assessment and communication of risks.

Opis:
Wreck of a ship is an incident that must be avoided. Ship accidents are generally caused by a several cases, such as human error, natural disaster, technical errors, missed communication, poor condition of the ship, and many more. Ship wreckage have huge impact for ship navigation, environment, economics, and others. Those impact have many disadvantages for the shipowners, and also for environment. For examples the fuel spills that pollute the environment, make disturbance to sailing ship because the track for those navigation is blocked by the ship wreck and their cargo especially on shallow location (<50 m). These research will discuss the effect the container when it is floats on the sea and its interference other ships. The main objective of this study is to present a risk assessment on the environmental impact of the wreck and container cargo. Wrecks on the seabed is likely to pose a risk to passing ships. container and its contents as well as the possibility of refloat, and also their environmental risks emanating from the wreck and container cargo, such as fuels, lubricants, and chemical cargo. Variations scenario is a collision between ships that pass by floating containers. The frequency of refloating container, and the consequences of the passing ship depends on several factors, which will be the subject of research. However, because of the frequency of refloating containers is unlikely, then the risk is low and does not pose a danger to navigation. These risk assessment using risk matrix 5x5 which is the combined value of the frequency and consequences of the incident. The results of this study indicate the level of risk, whether the risk is accepted, not accepted or received by considering the costs and benefits (ALARP). To consequence, there are two parameters which energy is absorbed and the penetration occurs. The absorbed energy is divided into two, namely the energy absorbed by ship and the energy absorbed by containers. In this study were taken 5 groups based on the size of the vessel. In this cases any 5 size group of vessels is based on the size of the ships that pass in the shipping lanes at the site of the sinking. Assumed these vessels have speed 10 knots at the location. As well as speed drifting containers having 0 to 3 knots.

Opis:
The paper concerns the problem of uncertainty associated to risk analysis of complex technological systems; this problem is not easy to resolve and manage. This is because such uncertainty has never been simple to quantify and, despite several innovative techniques able to properly manage uncertainties are available, none of these methodologies is integrated on the risk analysis in order to evaluate the error propagation. Also the itself risk analysis is not a precisely defined procedure but rather a complicated process of several parts and, moreover, each part is characterized by its own uncertainty. Several studies highlighted as the phases which mainly contribute to the overall uncertainty of a risk analysis are consequence and vulnerability studies. In order to provide a signifying approach to the problem, the working team has decided to focus their attention on a very important target for population safety: the hydrogen refuelling station for automotive.

This article addresses current issues concerning the risk analysis and functional safety management. Some cost-benefit analysis methods (CBA) are presented oriented on optimizing the safety-related solutions on example of functional safety technologies reducing risk based on programmable systems E/E/PE (PN-EN 61508) and SIS (PN-EN 61511). The importance of safety-related criteria, such as tolerability of risk (TOR) in the context of cost-benefit analysis (CBA), is emphasized to reach rational decisions as regards safetyrelated solutions to be sufficiently reliable, safe and preferably economically justified.

Opis:
Many lives and aircrafts have been lost due to human errors associated with mental workload overload (MWLOL). Human errors are successfully considered in existing Fault Tree Analysis (FTA) methods. However, MWLOL is considered through Performance Shaping Factors indirectly and its information is hidden in FT construction, which is not conducive to analyze the root causes of human errors and risks. To overcome this difficulty, we develop a risk analysis method where Multiple Resources Model (MRM) is incorporated into FTA methods. MRM analyzes mental workload by estimating the resources used during performing concurrent tasks, probably including abnormal situation handling tasks introduced by basic events in FT. Such basic events may cause MWLOL and then trigger corresponding human error events. A MWLOL gate is proposed to describe MWLOL explicitly and add these new relationships to traditional FT. This new method extends previous FTA methods and provides a more in-depth risk analysis. An accident, a helicopter crash in Maryland, is analyzed by the proposed method.
