Opis:
Legal regulations regarding the procedures and safe use of airspace can not keep up with the rapid development of the commercial use of unmanned aircraft. For the ”Safety Case” for unmanned remote systems RPAS in the aspect of human factor, HRA methods – Human Reliability Analysis and Bow Tie Analysis were used. Hazard analysis and risk assessment for RPAS flights was carried out. Due to the remote control flights, analysis of the problem focuses on the actions of the human factor. The presented ”Safety Case”, using the HRA and ”Fly Analysis” methods identifies hazards, determines risk indicators and points the tolerance levels of risks. The specific measures to reduce the likelihood and/or severity of possible adverse events are suggested. The presented model can be used as a risk management tool..

Opis:
The objective of this paper is to demonstrate that a combination of a behavior-based monitoring process—using an at-risk behavior and unsafe condition observation system—and an observation-based safety adherence monitoring process that can indicate the compliance level with well-defined and agreed safety critical aspects and operational practices and procedures will be an effective safety management tool. This tool herein described represents a particular case, developed by a Praxair Inc. subsidiary in Brazil. Other safety surveillance systems usually adopted in industrial environments can rarely be used on construction sites. They also do not share information, knowledge and skills among the safety staff and other professionals invited to observe, usually covering specific tasks or specific professionals only, not a complete working area, which causes functional observing and monitoring limitations in terms of capturing behaviors and environmental safety issues. This tool also offers a wide range of learning opportunities and continuous improvement.

Opis:
The presented paper is an attempt to evaluate the application of different buffer sizing methods (within the critical chain approach) to a real-life project, in order to show that it is important to choose consciously one of the existing methods. The implementation of the different approaches to the buffer sizing procedure resulted in eight unique schedules. Once all the methods were implemented, the authors of this paper stumbled upon 2 inconveniences (slack vs. buffer, splitting up buffers). Funding solution for these handicaps caused obtaining eight more schedules. In order to evaluate all the determined solutions, the authors decided to establish a simulation study. A random dataset was generated of 2000 observations using the mean and variance calculated for the probability distribution determined by three possible durations (optimistic, expected and pessimistic) given by the project team members. To validate the performance of different methods, two penalty systems were designed. The test results indicate which specific buffer sizing technique performs best in the presented case, taking into account the attitude of the decision maker. The simulation study is the proposal of a method to be applied in each case of the critical chain method application, because it makes the use of the critical chain method more effective.

Opis:
International business demands seamless service and IT-infrastructure throughout the entire supply chain. However, dependencies between different parts of this vulnerable ecosystem form a fragile web. Assessment of the financial effects of any abnormalities in any part of the network is demanded in order to protect this network in a financially viable way. Contractual environment between the actors in a supply chain, different business domains and functions requires a management model, which enables a network wide protection for critical infrastructure. In this paper authors introduce such a model. It can be used to assess financial differences between centralized and decentralized protection of critical infrastructure. As an end result of this assessment business resilience to unknown threats can be improved across the entire supply chain.

The purpose of this paper is to analyze cognitive distraction data to determine its impact of transit bus drivers' capability. Much of the theory and results applied in this paper are from the work of researchers working on similar projects. In order to understand cognitive distraction and how it can be mitigated, a Cognitive Distraction Model is outlined. The model was analyzed to evaluate the correlation between driver capability, and demographics and driving patterns. A model that provides an understanding about cognitive workload and driver capability could provide better psychological solutions to mitigate the number of accidents due to cognitive distraction and develop relevant driver training programs. Through additional research from the neurological and behavioral sciences, regulators could develop a better understanding of the causal factors and ways to control cognitive distraction.

Opis:
The catering industry is developing rapidly in China. Statistics in 2002 indicated that there were over 3.5 million dining places in China, hiring over 18 million people. However, the accident rate was high. Occupational health and safety (OHS) has to be watched more carefully. It is proposed to develop an OHS management system for the catering industry and to integrate it with an ongoing management system by referring to OHSAS 18001:1999. The first step is risk identification and evaluating the major factors concerned by referring to the codes in China, the list of occupational diseases, operation rules, requirements of the law, and records of past incidents. The technological aspect has to be considered in working out the safety strategies. This includes technical measures in accident prevention at the workplace. The kitchen is the main area to be focused on. Methods for hazard identification and risk assessment of dangerous factors in kitchens are proposed in this paper.

Opis:
The article deals with problems connected to crisis management regarding mining companies. In accordance with adequate decrees, mining companies, including mining plants, belong to objects towards which crisis management rules should be applied. In mining plants, apart from underground threats, ground threats that lead to a crisis situation might also emerge on the entrepreneur’s territory. By this reason, they should be guided by the principles for the preparation for their special protection through conceptual, planning, organizational, logistic, technical, training and control activities taken to develop, agree and update specific protection plans, implement projects under the alert and notification system, and exchange information on threats. A summary of possible hazards to a particular site and a separate mining plant facility, assessment and risk control are essential to develop a safety concept and prevent risks. There is a need of continual analyses of potential threats and actions taken to eliminate them, and if they occur the rapid response of individual services and appropriate integrated rescue operations.

Opis:
In this paper, we introduce a new risk evaluation model for evaluating the navigation safety zone for an entire ship route. This model considers a new algorithm to determine the navigational safety zone in real-time, and also takes the navigation officers’ perception while navigating a ship into consideration. The risk quantification has been developed using a questionnaire and incorporated into the new model. A simulation was carried out for the Osaka bay area in order to verify the usefulness of the proposed model. A new approach was employed to monitor the level of navigation safety along a ship route. The entire ship route is divided into small sections as a gridded matrix. The level of navigation safety can be quantified by means of a safety index on the basis of the ship’s navigation data within a specified distance range. The results show that the comparison between risks identified for different sections across the entire ship route is easy, which helps determine the navigational safety zone quickly. This model is expected to be able to serve as a new tool for managing safety throughout an entire ship route area in real-time in order to support the port safety authority or vessel traffic service center.

Opis:
The mathematical model of portfolio optimization is usually represented as a bicriteria optimization problem where a reasonable trade-off between expected rate of return and risk is sought. Im a classical Markowitz model the risk is measured by a variance, thus resulting in a quadratic programming model. As an alternative, the MAD model was proposed where risk is measured by (mean) absolute deviation instead of a variance. The MAD model is computationally attractive, since it is transformed into an easy to solve linear programming program. In this paper we poesent a recursive procedure which allows to identify optimal portfolio of the MAD model depending on investor's downside risk aversion.

Opis:
PURPOSE: The aim of the paper is to map the thematic landscape of real estate research in the context of risk management and to contribute to the identification and exploration of relationships between specific constructs in the management versus finance research. DESIGN/METHOD: This article applies some scientometric techniques. A combination of topic mapping has been used, as well as the author’s and journal co-citation analyses, and overlay visualisation of main and new topics in these fields. For the purposes of bibliometric analysis, the following tools and techniques have been used: trend analysis of the number of publications, citation analysis, the word co-occurrence method, and clustering (cluster analysis). The VOSviewer software and the data analysis tools available in the SCOPUS database were used for the analysis. RESULTS/FINDINGS: The main findings of this study are: the study of real estate issues in the context of risk management is a relatively new trend in academic research, which has been intensified over the past 10 years; the problems are studied mainly from the point of view of management research, financial research and engineering research; most of the leading researchers in this field combine aspects of management with aspects of finance in their studies; a relatively new trend in the study of the real estate issues in the context of risk management is the research on the use of artificial intelligence and the analysis of the impact of climate change on these processes. ORIGINALITY/VALUE: This article makes the important contribution to real estate research in the context of risk management in management research and finance research. The analyses revealed some patterns of convergence and divergence and the diversity of topics, specialisation, and interdisciplinary engagement in the context of real estate issues in the context of risk management in management and finance research, thus offering the latest insights into the state-of-the-art of the fields.

Opis:
ObjectivesSetting and implementing occupational exposure limits (OELs) is one of the measures taken to protect workers from adverse effects of hazardous chemicals. The EU Regulation on Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) introduced an additional kind of exposure guidance values for workers; namely, the derived no effect level (DNEL) for workers’ inhalation exposure (worker DNEL). About 500 substances have a Swedish OEL, while roughly 5000 substances have a worker DNEL derived by REACH registrants. This work aims to investigate how the Swedish OELs and worker DNELs are perceived at Swedish workplaces, and whether worker DNELs are considered a possible alternative to OELs when the latter are lacking.Material and MethodsAn online questionnaire was designed and sent to Swedish companies identified through the European Chemicals Agency’s database of registered substances (N = 126) and the Swedish Chemicals Agency’s registry of companies that import or manufacture notifiable chemical products (N = 227). The response rates were 52% and 38%, respectively.ResultsThe respondents stated that they were using the Swedish OELs and most of them considered these to be a suitable risk management tool. As about one-third of the respondents expressed that they had some experience in using substances without the Swedish OELs, there are certain data gaps that worker DNELs may fill. One-third of the respondents familiar with worker DNELs stated that they would consider using worker DNELs for substances without the Swedish OELs. However, nearly half of the respondents reported to be unfamiliar with worker DNELs.ConclusionsPoor familiarity with DNELs may pose an obstacle to properly recognizing DNELs’ potential as well as the possible limitations of individual DNELs. There is a need for education about DNELs, as well as for tools facilitating the evaluation of DNELs and OELs from other sources in cases where the applicable Swedish OEL is lacking.

zarządzanie ryzykiem
Opis:
Zarządzanie ryzykiem w (standardowym) modelu scrum realizowane jest tylko w sposób niejawny. Z przeglądu literatury przeprowadzonego przez autorów wynika, że brakuje podejść ilościowych do jawnego zarządzania ryzykiem w środowisku scrum. Prezentowane rozważania mają służyć ustaleniu, czy możliwe jest zarządzanie ryzykiem zgodnie z metodyką scrum w sposób ilościowy, na podstawie jawnej informacji o ryzyku podawanej w sposób lingwistyczny, a także przeanalizowanie zalet takiego podejścia. W artykule opracowana została także koncepcja umożliwiająca kwantyfikację określonych rodzajów ryzyka w sprincie. Prezentowane podejście ułatwia adaptację planu sprintu, w którym na wyjściu zwracany jest zbiór możliwych akcji naprawczych. Akcje te są skwantyfikowane pod kątem kryterium wartości biznesowej dla klienta, które określa się mianem wartości sprintu (ang. sprint value). Proponowane podejście zostało zaprezentowane wraz z przykładem ilustracyjnym. Z przeprowadzonych badań, wypełniających wspomnianą lukę badawczą, wynika, że w metodyce scrum można zastosować ilościowe zarządzanie ryzykiem, na podstawie jawnej informacji o ryzyku podawanej na wejściu w formie wyrażeń lingwistycznych.
Risk management in (standard) Scrum is handled only implicitly. The authors’ literature review shows that there is a lack of quantitative approaches to explicit risk management in Scrum. The aim of this work is to analyze whether it is possible to manage risk in Scrum in a quantitative way, based on explicit risk information provided in a linguistic form as well as analyzing the advantages of this approach. A concept enabling the quantification of risks in a Sprint has been developed. The approach presented in the article makes it easier to adapt a Sprint plan. In this approach, a set of possible corrective actions of the plan are returned as an output. These actions are quantified in terms of the criterion of business value for the Customer, which is called the Sprint Value. The approach is presented on an illustrative example. The research fills the research gap that was mentioned above. Based on the research conducted, it was found that quantitative risk management can be used in Scrum, based on explicit risk information provided in a form of linguistic expressions.
