Opis:
This article studies differences in the results of using different risk estimation tools in the same hazardous situations involving dangerous machinery. We investigated how (a) types of risk estimation parameters and methods of constructing tools, (b) the number of levels of each parameter, and (c) the number of risk levels influence the results. Consequently, 31 risk estimation tools were compared by using them to estimate risk levels associated with 20 hazardous situations. Risk estimation appears to be tool-dependent, as different tools give different results with identical hazardous situations. The scope of the tool, its use, and construction could explain these differences. This article also proposes a series of rules for constructing tools to alleviate many problems associated with the variability of risk estimations.

Opis:
Risk is a category that is inseparably connected with uncertainty and probability, which means that the nature of risk as a category of science is complex, and the concept of risk is very difficult to define by one conceptual system of modern science. Due to the above, the main research hypothesis of the work is oriented to the assumption that the complexity of the risk category is determined by the diversity (variety) of reality, as a result of which in science there is currently no uniform methodology for risk assessment and estimation. As a result, the main goal of the article is to describe the research area based on selected representative methods of risk estimation and logical decision-making schemes, as well as to systematise the knowledge about the methodology used in them. In the article, the authors illustrate risk estimation with examples developed by themselves and quoted from various fields of science, differing from one another in formal terms in quantitative and qualitative (numerical and content-verbally) dimensions. Strategic risk, risk of fraction estimation, Bayesian risk, Bayesian methods for estimation of population distribution parameters, risk of econometric model assessment, interest rate risk, banking risk, and adverse event as a measure of risk are here addressed. The article also focuses on the problem of risk estimation in terms of the theory of fractals. The work is to have not only cognitive but also practical meaning. The created source of knowledge should prove helpful for decision-makers in the area of management since effective process management requires the expertise of risk estimation in various dimensions and using various mathematical tools.

Opis:
The paper addresses the issue of estimation risk in VaR testing. The occurrence of estimation risk (also called parameter uncertainty) implies that the observed VaR violation process may not fulfil the standard requirements that underpin the testing framework. As a result, VaR tests may reject correct VaR models due to estimation errors committed when predicting the VaR. The paper examines the robustness of VaR tests to estimation risk. The research is based on an observation indicating that certain elements of a forecasting scheme have a significant influence on estimation risk. Thus, the article extends the previous studies to include several more realistic forecasting schemes than those based solely on a fixed window. The aim of the research is twofold: firstly, to find methods of mitigating the negative impact of estimation risk on VaR tests, and secondly, to provide a comprehensive comparison of VaR testing methods with reference to the issue of estimation risk. The conducted analyses demonstrate that a proper adjustment of the forecasting scheme yields better results in terms of the accuracy of the tests than correcting estimation errors by means of the subsampling technique.
Artykuł dotyczy problemu ryzyka estymacyjnego przy testowaniu VaR. Występowanie ryzyka estymacyjnego (zwanego również niepewnością parametrów) oznacza, że obserwowany proces przekroczeń VaR może nie spełniać standardowych wymogów określających ramy testowe. W konsekwencji testy VaR mogą odrzucać prawidłowe modele VaR ze względu na błędy estymacji popełnione podczas wyznaczania prognoz VaR. W badaniu omawianym w artykule oceniana jest odporność testów VaR na ryzyko estymacyjne. U podstaw badania leży spostrzeżenie, że ryzyko estymacyjne w istotny sposób zależy od elementów schematu prognozowania. Z tego powodu w badaniu uwzględniono schematy prognozowania bardziej realistyczne niż schemat oparty na ustalonym oknie, co stanowi rozszerzenie w stosunku do wcześniej prowadzonych badań. Cel badania jest dwojaki: znalezienie metod, które pozwalałyby zniwelować negatywny wpływ ryzyka estymacji na testy VaR, oraz kompleksowe porównanie metod testowania VaR w odniesieniu do problemu ryzyka estymacyjnego. Przeprowadzone analizy wskazują m.in. na to, że odpowiednie dostosowanie schematu prognozowania daje lepsze wyniki pod względem dokładności testów niż korygowanie błędów estymacji techniką podpróbkowania.

Opis:
Increasing number of bankruptcy announcements means that even greater attention is being paid to the correct evaluation of the probability of default (PD) and decisions made on the basis of it. Reliable estimation of the likelihood of a company’s bankruptcy reduces risk, not only for the company itself but also for all co-operating companies and financial institutions. The financial crisis has led to a tightening up of the conditions for gaining finance from banks. However, it is not only the evaluation of PD itself that is so important but also the correct classification of companies according to their PD level (“good” or “bad” companies). There is very little consideration about possible adjustments of the credit risk scale, as usually the American scale is adopted with no changes which seems incorrect. This paper stresses the importance of correct calibration of the credit rating scale. It should not be assumed (as it was in the past) that once a scale is defined it remains fixed and independent of the country. Therefore, the research carried out on Polish companies shows that the credit rating scale should be changed and the default point (i.e. “cut-off” point) should be higher than in the past. The author uses a modified classification matrix based on the probability of default. The paper compares the classification of quoted Polish companies according to their credit risk level (PD) with the actual occurrence of default when various default “cut-off” points are used.

Opis:
In the safety engineering, the most frequently disadvantage in risk estimation is the lack of data. In such cases, we have to rely on subjective estimations made by persons with practical knowledge in the field of interest, i.e. experts. However, in some realistic situations, they may have uncertainty in the perceiving and evaluation of the problem considered or limited knowledge of the rare events, such as the consequences of the seagoing ship propulsion failures. The probabilistic models of the risk estimation turn out to be insufficient in modelling the subjective uncertainty. The fuzzy methods are viewed to be powerful in dealing with ambiguity and uncertainty that can be used to handle with the subjective estimation. This article addresses the intuitionistic fuzzy method in the subjective estimation of the ship propulsion failure consequences as rare event risk. In the article, a subjective model of the ship propulsion risk is developed as scenarios of the different subsequent consequences of loss of ship propulsion function until a seriously severe accident resulting in loss of seaworthiness. The model proposes an approach combining AHP method and intuitionistic fuzzy method to assess the occurrence probability and severe probability of these rare events based on the expert opinions. In order to show the applicability of the proposed model, a study case of the propulsion risk of the container carrier operating on the North Atlantic lines is conducted.

Opis:
Today, the advantage of enterprises is built by the process of innovations implementation. A decision concerning the innovations implementation is always difficult and risky because innovations are specific kinds of investments and are a potential source of many threats. This is why before taking a decision about an implementation of a given solution, it is extremely important to make an analysis of its consequences. A risk analysis becomes more and more important in this aspect because it makes it possible to estimate the level of dangers which can be caused by a new investment solution. This is why the process of estimating innovation risk with the use of Bayesian networks has been presented in this work. Data from projects carried out under the Operational Programme Innovative Economy for the years 2007-2013 in Opole Province and the NETICA programme have been used in order to work out an exemplary method. It has been shown how to determine the innovative risk level with taking into consideration the adopted assumptions. Exemplary factors of the analysed risk concerning both the enterprise and the sheer undertaking have been characterised. In the first step, the most important factors of innovation risk and their measuring indicators have been specified. Assuming that the risk is a probability of an undesirable state occurrence (according to a negative concept), the authors have chosen the following indicators to estimate the danger of an innovation failure: W 1. Period of using technology in the world. W 2. Time of carrying out the project expressed in months. W 3. Value of the whole project. W 4. Size of the enterprise. W 5. Own financial resources designed for making innovation. W 6. Financial risk. W 7. Decision about granting a subsidy. The chosen factors (sources) of risk are only an exemplary set and were chosen on purpose from the point of view of an area of the analysed risk. It is necessary to remember that each potential source of danger can become the basis of a subsequent risk connected with the project being carried out. In this context, an aspect of choosing appropriate and the most important risk sources, from the point of view of the innovation efficacy, appears. It is an extremely important stage because as we know it is impossible to take into consideration all factors because the assessment of accuracy of the estimated risk shall depend on it. In this case authors also highlight the role of an expert who mainly directs the risk estimation process. This step is a little subjective but in reality, the subjectivity is present in almost every step of risk analysis. The next step included the specification of dependencies between the enumerated factors and the probability of the analysed states occurrence. Thanks to that, the elaboration of a simple Bayesian network has become possible. It has been shown, on its basis, how the level of innovation risk an be estimated if the specific information and assumptions are available.

Opis:
Environmental risk assessment is one of the key tools in environmental engineering. This risk assessment can be qualitative or quantitative and it is based on preliminary studies i.e., baseline study for waste disposal sites. Even though the literature exists on baseline study in general, still there is a lack of guidance regarding development of a site-specific baseline study model for a waste disposal site. This study has two-fold aim, firstly, how to develop site-specific baseline study model for a selected dumping site, and secondly, how this site-specific baseline study can support the environmental engineering via mathematical risk estimation. Mahmood Booti Open Dumping Site (MBODS) is selected to demonstrate the development and application of site-specific baseline study model. This is followed by building a framework that shows how the output of the baseline study can lead to environmental engineering via mathematical risk estimation. The paper provides a mechanism of how to construct a bespoke baseline-study model that is readily useable, avoiding procurement of expensive computer software and yet smoothly connecting with the follow-on stages of the risk assessment. The work presented in this paper can be reproduced repeatedly to create site-specific baseline study models for risk assessment of other waste disposal sites in a cost-effective, consistent and cohesive manner.

Opis:
Among the risk assessment methods, failure modes and effects analysis (FMEA) is a popular, widely used engineering technique in many areas. It can be used to identify and eliminate known or potential failure modes to enhance reliability and safety of complex systems. In practice, risk estimations encounter difficulties connected with shortage of data. In such cases, we have to rely on subjective estimations made by persons with practical knowledge in the field of interest, i.e. experts. However, in some realistic situations, the decision makers might be unable to assign the exact values to the evaluation judgments due to his/her limited knowledge. In other words, there is a certain degree of hesitancy in human cognition and his/her judgment, who may have insufficient knowledge of the problem domain or uncertainty in assigning the evaluation values to the objects considered. In order to deal with ambiguity and uncertainty in the imperfect information, there have been recently proposed many various such theories as fuzzy sets, interval-valued fuzzy sets, type-2 fuzzy sets, hesitant sets, grey sets, rough sets and intuitionistic fuzzy sets. They have drawn more and more attention of scholars and been adopted in many applications This article addresses the Atanassov’s interval-valued intuitionistic fuzzy sets and FMEA methods in the risk estimation of the system failures based on the expert judgments.

Opis:
In this paper, we extend the analytic hierarchy process (AHP) method and the Atanassov’s intuitionistic fuzzy set (IFS) into the intuitionistic fuzzy analytic hierarchy process (IFAHP) with application in ship system risk estimation. In the safety engineering, risk estimation is in practice confronted with difficulties connected with shortage of data. In such cases, we have to rely on subjective estimations made by persons with practical knowledge in the field of interest, i.e. experts. However, in some realistic situations, the decision makers might be reluctant or unable to assign the crisp evaluation values to the comparison judgments due to his/her limited knowledge. In other words, there is a certain degree of hesitancy in human cognition and his judgment. Taking advantages of IFSs in dealing with ambiguity and uncertainty into account, the IFAHP can be used to handle with the subjective preferences of experts, who may have insufficient knowledge of the problem domain or uncertainty in assigning the evaluation values to the objects considered. This paper also develops a new knowledge-based ranking method to derive the priority vector of the hierarchy. An illustrative example of the propulsion risk estimation of container carriers operating on the North Atlantic line is given to show the applicability and effectiveness of the proposed method.

W artykule przedstawiono, skomentowano oraz podano przykład zastosowania metody oceny ryzyka zarysowania zdefiniowanej w wytycznych Weiße Wannen. Metoda ta polega na doborze stabelaryzowanych wartości liczbowych odpowiadających poszczególnym założeniom projektowym, co w kolejnym kroku poprzez ważony wskaźnik pozwala ocenić stopień ryzyka wystąpienia nieszczelności w płytach fundamentowych.
One of the basic service conditions in the case of foundation slabs is to ensure their water-tightness due to the possible periodic or constant pressure of groundwater. Therefore, the article presents, comments on and gives an example of the application of a method of crack risk assessment as defined in the Weiße Wannen guidelines. This method is based on the selection of tabulated numerical values corresponding to individual design assumptions, which in the next step, through the weighted indicator, allows to assess the degree of risk of leakage for foundation slabs.

Opis:
This paper presents occupational skin exposure to solar ultraviolet radiation (UVR) of 122 Polish outdoor workers in spring and summer. In 65% of the cases, it was significant and exceeded 10 standard erythema doses (SED) during a work shift. The results provided grounds for (a) modifying hazard assessment based on the skin exposure factor proposed by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) and (b) developing a criterion of risk estimation. The modified method uses the UV index (UVI) instead of the geographical latitude and season factor. The skin exposure factor (Wes) of one is the criterion of risk estimation. Risk is low if the estimated value of Wes does not exceed one. If it does, suitable preventive measures are necessary and a corrected skin exposure factor (Wes *) is calculated to minimize its value to at least one. Risk estimated with that method was high in 67% of the cases.
