This article summarizes avionics safety-critical software development methodologies and implications of the DO-178C standard from an Agile application perspective. We explain the safety-critical software categorization. It also outlines the main differences and advantages of different approaches to the development process, from Waterfall through the V-model to Iterative and Incremental. Agile principles are explained as well as a Scrum – which is a popular framework in the non-safety-critical software industry. The application of Agile, for safety-critical software considerations, is based on the practical knowledge of the authors, and looks at the potential solution from a DO-178C standard, size of the project, scalability, and organizational culture points of view. Definition of the Agile type of framework, consistent with the certification process and existing standards, has been highlighted as a potential game-changer for the avionics industry.

The analyses were aimed at determination of failure effects in the transmission system, which allow identifying the transition process of the system from a safety state (it may not be necessarily a failure - a free state) to a dangerous state and permit to calculate probability of the dangerous state occurrence of the system as a failure effect to the operating system. Dangerous states of the safety Fieldbus system are mainly caused by systematic failures within a specification of the system, electromagnetic interferences (EMI) and random failures of the HW effects. The effects of electromagnetic interferences and random failures of HW can be described in the paper by the use of time table.

Opis:
A safety-critical avionics system has to qualify the performance related requirements and the safety-related requirements simultaneously. This paper presents a comprehensive study on the reliability analysis method for safety-critical avionics system by using dynamic fault tree approach based on Markov chain. The reliability models were constructed applying dynamic fault tree (DFT) modeling method according to deeply analysis of the typical failure modes, causes and influence of the safety-critical avionics system by considering the aspect of repairable feature and redundancy. Taking into account the both failure phenomenon of safetycritical avionics system and many uncertainties exist in the fault status and fault reasons, fuzzy sets theory is introduced into dynamic fault tree method. Specifically, it adopts expert elicitation and fuzzy set theory to evaluate the failure rates of the basic events for safety-critical avionics system. Furthermore, the fuzzy dynamic fault tree analysis method for safety-critical avionics system based on the consecutive parameter Markov chain is proposed. The modularization design was utilized to divide the dynamic fault trees into static and dynamic sub-trees. The static tree was solved by binary decision diagram (BDD) and the dynamic tree was solved by Markov chain method. The results show that the proposed method is more flexible and adaptive than conventional fault tree analysis for fault diagnosis and reliability estimation of safety-critical avionics system.
Krytyczne dla bezpieczeństwa układy elektroniki lotniczej (awioniki) muszą jednocześnie spełniać zarówno wymogi eksploatacyjne jak i wymagania związane z bezpieczeństwem. W niniejszej pracy przedstawiono kompleksowe opracowanie dotyczące metody analizy niezawodności krytycznych dla bezpieczeństwa systemów awioniki wykorzystującej opartą na łańcuchu Markowa metodę dynamicznego drzewa błędów. Modele niezawodności konstruowano z zastosowaniem metody dynamicznego drzewa błędów zgodnie z przeprowadzoną dokładną analizą typowych przyczyn uszkodzeń oraz czynników wpływających na systemy elektroniki lotniczej, z uwzględnieniem aspektu naprawialności i nadmiarowości. Biorąc pod uwagę, że zarówno ze zjawiskiem uszkodzenia krytycznego dla bezpieczeństwa systemu awioniki jak i ze stanem awarii i przyczynami błędów wiąże się wiele niepewności, metodę dynamicznego drzewa błędów poszerzono o teorię zbiorów rozmytych. W szczególności, zaproponowana metoda wykorzystuje ocenę ekspercką oraz teorię zbiorów rozmytych do oceny intensywności uszkodzeń dla podstawowych zdarzeń zachodzących w krytycznych dla bezpieczeństwa systemach elektroniki lotniczej. Ponadto zaproponowano metodę analizy krytycznych dla bezpieczeństwa systemów awioniki wykorzystującą teorię rozmytych dynamicznych drzew błędów opartą na markowowskim łańcuchu następujących po sobie parametrów. Budowę modułową wykorzystano do podziału dynamicznych drzew błędów na poddrzewa statyczne i dynamiczne. Drzewa statyczne rozwiązywano za pomocą binarnego schematu decyzyjnego (BDD) a drzewa dynamiczne – metodą łańcuchów Markowa. Wyniki pokazują, że proponowana metoda diagnozowania błędów i oceny niezawodności krytycznych dla bezpieczeństwa systemów elektroniki lotniczej jest bardziej elastyczna i łatwiejsza do adaptacji niż konwencjonalna analiza drzewa błędów.

In the paper, design flow of the application specific logic controllers with increased safety by means of Petri nets is proposed. The controller architecture is based on duplicated control unit and comparison results from both units. One specification of control algorithm is used by means of Petri net for both units. The hardware duplication is obtained during dual synthesis process. This process uses two different logic synthesis methods to obtain two different hardware configurations for both control units. Additionally, the dual verification is applied to increase reliability of the control algorithm. Such design flow simplifies the process of realization of control systems with increased safety.

Critical infrastructure plays a key role in the functioning of the state and the lives of its citizens. Due to natural disasters or those being a consequence of human activities, critical infrastructure can be destroyed or damaged, and its functioning can be disrupted, which can pose a threat to the lives and property of the citizens. Simultaneously, such events negatively affect the economic development of the state. That is why protection of critical infrastructure is one of the state’s priorities. In the years 2015 and 2016, NIK examined the regularity of the protection of critical infrastructure items. The audit was also a response to numerous media reports on failures or incidents that could pose a threat to critical infrastructure items in the country. The audit comprised selected critical infrastructure administrators, the Government Security Centre, regional governors and local self-government units.

Opis:
Certain critical infrastructure networks show some interconnections, relations and interactions with other ones, most frequently when located and operating within particular areas. Failures arising within one critical infrastructure network, can then negatively impact not only on associated systems, societies and natural environment, but also on mutual critical infrastructure networks. Therefore, interdependent critical infrastructure networks can be determined as network of critical infrastructure networks (network of networks approach). The paper presents safety analysis of the network of critical infrastructure networks, taking into account interconnections, relations and interactions between particular ones. Critical infrastructures networks as multistate systems are considered, by distinguishing subsets of no-hazards safety states, and crisis situation states, and by analysing transitions between particular ones. Issues introduced in the article are based on the assumption that one key critical infrastructure network impacts on functioning of other critical infrastructure networks - can reduce their functionality and change level of their safety and inoperability, furthermore, other networks can impact each other, too. Safety characteristics of network of critical infrastructure networks: safety function, mean values and standard deviations of lifetimes in particular safety state subsets, are determined, taking into account interdependencies between particular networks. The results are related to various values of coefficients defining the significance of influence of interdependencies among networks.

In the paper the safety function of a multistate series network with dependent assets, with dependent subnetworks and with dependent assets of its subnetworks is determined. The multistate series-parallel network with dependent assets of its subnetworks and multistate series-“m out of k” network with dependent assets of its subnetworks is considered. Further the multistate parallel and “m out of n” networks with dependent assets are analyzed. The safety function of multistate parallel-series and “m out of l”-series networks with dependent assets of its subnetworks, and finally of multistate parallel-series and “m out of l”-series networks with dependent subnetworks and dependent assets of these subnetworks are determined. Proposed theoretical models of dependency are applied to the safety analysis of the exemplary electricity network. Finally, the obtained results are compared with results for the considered electricity network without assumption about dependencies between assets and subnetworks.

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:
Identification of boundary values and features which describe a system operation safety is a crucial problem for assessment of the system operation safety. In this article, an attempt to match features necessary for a description of a given system operation safety and determine their boundary values, has been made. Determination of boundary values of safety features will allow to evaluate the system safety level. The following variables have been accepted as safety features: the number of accidents, the number of fatalities, and the number of people injured in those accidents. According to these values, probability values of the numbers of people who were killed and who were injured in those accidents have been established. Probability value equal to zero has been accepted as the intentional state, the interval between 0 and the mean value of a given feature determines the acceptable state, the interval between the mean value of a given feature probability and value 0.1 determines the boundary state, whereas all features assuming values higher than 0.1 refer to the system critical state. The presented research results are considered as directives for development of safety criteria for road transport systems and determination of their critical values. The proposed method of boundary values determination can be used for assessment of safety for different transport systems.

The paper presents a general approach to safety analysis of critical infrastructures that aims to suggest new and to develop existing methods and tools capable of supporting intelligent modeling and decision making in controlling and optimizing the safety of those systems and their accidents consequences risk. Its main focus is on the suggestions of the creation and usage of new techniques, procedures and strategies to improve and to optimize safety of real complex infrastructure systems related to the inside dependencies – among their subsystems and components and the outside dependencies – coming from their operation environment and from other dangerous events and natural hazards. The approach tries to create an original and coherent methodology of safety of critical infrastructures useful in ensuring and improving safety of those systems in various industrial sectors by providing an integrated package of solutions consisting of various packages of theoretical and practical tools ready for direct use by safety theoreticians and practitioners dealing with safety of real critical infrastructures.

Bezpieczeństwo jest jedną z najważniejszych potrzeb człowieka oraz jednym z najważniejszych zadań państwa. Szczególnie ważne są w tym aspekcie zakłady, które mają znaczenie strategiczne dla obronności państwa oraz infrastruktura krytyczna. Jednak coraz częściej największe znaczenie mają aspekty ekonomiczne, co skutkuje tym, że zakłady strategiczne, powierzają ochronę podmiotom zewnętrznym. W artykule została podjęta problematyka ekonomicznych uwarunkowań bezpieczeństwa w zakładach o znaczeniu strategicznym w kontekście tworzenia własnych spółek ochrony przez te zakłady. W pierwszej części artykułu zwrócono uwagę na pojęcie infrastruktury krytycznej i jej znaczenia dla obronności państwa. Dalej podjęto problematykę zasadności tworzenia własnych spółek ochrony w kontekście ekonomicznym oraz niematerialnym, związanym z budowaniem etosu organizacji.
Security is one of the most important human needs and one of the most important tasks of the state. Especially important in this aspect are plants that are of strategic importance to state defense and critical infrastructure. However, economic aspects are becoming more and more important, which results in the fact that strategic plants entrust protection to external entities. The article addresses the issue of economic security considerations in plants of strategic importance in the context of the creation of their own companies of protection by these companies. The first part of the article draws attention to the notion of critical infrastructure and its importance for state defense. Further, the issue of the legitimacy of the creation of their own security companies in the economic and non-material context of the ethos of the organization was further discussed.

The optimization problem allowing to find the optimal values of the transient probabilities of the critical infrastructure operation process at the particular operation states that minimize the critical infrastructure operation cost mean value in the safety states subset not worse than a critical safety state is presented. The optimization of operation cost of the critical infrastructure is proposed with considering climate-weather change process influence on the system safety.

Opis:
This article addresses an integrated safety and security analysis approach of hazardous industrial plants and systems of critical infrastructure. Nowadays due to new hazards that emerge there are opinions among experts that these issues require an integrated approach in life cycle, from the design concept, through the design and operation of the plant, to its decommissioning. It is proposed to start from an interesting methodology known as the security vulnerability analysis (SVA) developed for hazardous plants of chemical industry. It is based on rings of protection concept to secure widely understood assets. This concept seems to be compatible with layer of protection analysis (LOPA), which is consistent with functional safety concept of the control and protection systems including cyber security aspects. It is outlined how to use these approaches in an integrated way for safety and security analysis of hazardous industrial plants and systems of critical infrastructure.

Opis:
A new approach to safety investigations of multistate complex systems with dependent components at variable operation conditions called critical infrastructures is proposed. The safety function of the critical infrastructure system is defined and determined for an exemplary “m out of l” critical infrastructure. In the developed model, it is assumed that the system components have the multistate exponential safety functions with interdependent departures rates from the subsets of the safety states. The approach is adapted to safety prediction of oil piping transportation system operating at a maritime port.

Opis:
Zmiany regulacji prawnych wymusiły konieczność szczegółowego zainteresowania się zagadnieniem związanym z problematyką wyznaczania, ustanawiania i likwidowania filarów bezpieczeństwa od źródeł zagrożenia wodnego, zwłaszcza przez geologów górniczych i kierowników ruchu zakładu górniczego, na których wprost spadł ten obowiązek. Jest to zagadnienie złożone, co potęguje fakt, iż obowiązujące przepisy nie przewidują dodatkowych regulacji dotyczących klasyfikacji zagrożeń, które współwystępują w danej przestrzeni (tzw. zagrożeń skojarzonych). W pracy, na tle klasyfikacji źródeł zagrożenia wodnego, autorzy przedstawiają wymagania formalno-prawne wyznaczania filarów bezpieczeństwa w podziemnych zakładach górniczych wydobywających węgiel kamienny. Ponadto scharakteryzowano powszechnie stosowane zasady wyznaczania krytycznego wymiaru filara bezpieczeństwa wraz z istotną zdaniem autorów, genezą ich powstania. Jednocześnie za problematyczne uznano ewentualne, bezkrytyczne próby zastosowania podawanych w literaturze wzorów, zwłaszcza w kontekście wyrobisk korytarzowych prowadzonych w skałach płonnych, w określonych warunkach górniczo-geologicznych.
Amendments to legal regulations forced the necessity of a special interest in the issue related to the problem of determination, establishing and eliminating safety pillars from the sources of water hazard. This applies mainly to mining geologists and high mining plant managers who have to do it this obligation. This is a complex issue. Existing law regulations do not provide for additional regulations regarding the classification of risks occurring together. In the article the authors present formal and legal requirements regarding the necessity of determining safety pillars in underground coalmines. They also describe their classification. Presented and reminded of the principles commonly used to determine the critical dimension of the safety pillar with the genesis of their emergence. Problematic is the fact that the patterns used in the literature are uncritically formulas especially in the context of advanced gallery workings without coal in specific mining and geological conditions.

Opis:
Awarie sieci elektroenergetycznych spowodowane siłami przyrody są częstym zjawiskiem występującym lokalnie, które może być opanowane przez służby operatora sieci. Jeśli jednak uszkodzeniu ulegnie duża liczba elementów na znacznym obszarze następuje pozbawienie zasilania sporego terenu. Wówczas zachodzi konieczność uruchomienia pomocy zewnętrznej i podjęcia działań kryzysowych (m.in. powołanie sztabu kryzysowego, pomoc dla ludności, powołanie zespołów odbudowy awaryjnej, stworzenie zaplecza logistycznego w tym linii zapasowych). Taka awaria dotknęła także Polskę. W nocy z 7 na 8 kwietnia wystąpiły silne wiatry i obfite opady mokrego śniegu, który osadził się na przewodach linii energetycznych, przekraczając co najmniej o kilkadziesiąt procent zakładane normy katastrofalne. W efekcie ponad 650 tys mieszkańców województwa zachodniopomorskiego na prawie dobę w przypadku Szczecina i ponad 32 godziny w przypadku mniejszych miejscowości została odcięta od dostaw energii elektrycznej. Po 10 latach, które upłynęły od tzw. Blackoutu pojawia się pytanie czy ryzyko wystąpienia ponownej awarii systemu w Szczecinie i okolicach jest możliwe? W artykule podjęta została próba odpowiedzi na nurtujące mieszkańców pytanie.
Electricity grids failures, caused by the natural forces, occur often locally and can be handled by the grid’s operator services. If, however, a large number of elements are damaged over a vast area, a large territory is devoid of power supply. It is then necessary to use external aid and undertake a crisis management operation (i.a. to set up a crisis team, secure humanitarian aid, establish emergency restoration task forces, and develop logistic facilities, including the reserve power supply lines). Such an electricity grid failure afflicted also Poland. On the night from 7 to 8 of April 2008 strong winds arrived and heavy wet snow was deposited on the electric power lines, exceeding several dozen times their assumed catastrophe endurance norms. As a result, over 650 thousand inhabitants of the Zachodniopomorskie Voivodship were cut off from the power supply for almost 24 hours in Szczecin, and for more than 32 hours in the smaller localities. After a decade since the so called ‘blackout’, a question arrives whether Szczecin and its vicinity are at risk of return of the system failure? In this article an attempt was made to answer this question that bothers the region’s inhabitants.

Opis:
This article provides insights into proactive safety management and mitigation. An analysis of accident reports reveals categories of supervening causes of accidents which can be directly linked to the concept of generic competencies (information management, communication and coordination, problem solving, and effect control). These findings strongly suggest adding the human element as another safety-constituting pillar to the concept of ship safety next to technology and regulation. We argue that the human element has unique abilities in dealing with critical and highly dynamic situations which can contribute to the system’s recovery from non-routine or critical situations. By educating seafarers in generic competencies we claim to enable the people onboard to successfully deal with critical situations.

Modelling of operation process influence on safety of a critical infrastructure is presented. New safety and resilience indicators for a critical infrastructure are defined and procedures of their determination in the case of the created model are proposed. Next, this model is applied to safety and resilience analysis of the port oil terminal critical infrastructure impacted by its operation process and the results are compared to the indicators of this critical infrastructure without operation impacts.

Opis:
We propose a unified model for the enforcement of safety and security of cyber-physical systems in critical applications. We argue that the need for resilience of a critical system requires simultaneous protection from hazards (safety) and from unauthorized access (security). We review how the critical system properties are handled and present a framework for their modeling. Then we present a model for the enforcement of critical system properties through situational awareness, including threat monitoring, data analysis and state prediction for decision making. We conclude by presenting a case study of a power grid simulation and advocate the ability to move from today's reactive approaches to proactive ones that aim at avoiding system failures.
