This article deals with modelling and analysis of the reliability of complex systems that use one-shot items during their operation. It includes an analysis of the impact of the reliability of used one-shot items on the resulting reliability of the system as a whole. Practical application of theoretical knowledge is demonstrated on an example of a model of reliability of an aircraft gun that was used for optimization of the gun’s design during its development and design. The analysed gun uses two types of one-shot items – rounds intended for conducting of fire and special pyrotechnic cartridges designed for re-charging a gun after a possible failure of the round.

There is presented a practically well grounded approach concerned with the identification, evaluation, prediction and optimization of reliability, availability and safety of technical systems related to their operation processes. The main emphasis of this approach is on multi-state systems composed of ageing components and changing during the operation processes their structures and their components reliability and safety characteristics. There are proposed the convenient tools for analyzing these systems in the form of semi-markov modeling the systems’ operation processes and multistate modeling the systems’ reliability. There are described theoretical results of the proposed approach to reliability and safety analysis of multistate systems with degrading components in their operation processes and the possibility of their practical applications to the reliability and safety analysis and optimization of the complex technical port and maritime transportation systems.

Practical application of the theoretical knowledge is demonstrated using a model of reliability of an aircraft gun that was used for optimization of the gun’s design during its development and design. Furthermore this paper demonstrates utilization of a proposed model to determine an optimum number of pyrotechnic cartridges that will achieve a required probability of fulfilment of the mission with the given reliability of individual subsystems of the gun, rounds and pyrotechnic cartridges. The proposed procedures of modelling and analysis of the reliability of complex systems with oneshot items were used in practice in designing and development of the PL-20 aircraft gun. Development of the gun was successfully finished in 2005, and the gun was fielded in the armament of the Czech Republic Air Force.

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.

There are presented general safety analytical models of complex multistate technical systems related to their operation processes. They are the integrated general models of complex technical systems, linking their multistate safety models and their operation processes models and considering variable at the different operation states safety structures and their components safety parameters. The conditional safety functions at the system particular operation states and independent of the system particular operation states the unconditional safety function and the risk function of the complex technical systems are defined. These joint models of the safety and the variable in time system operation processes are constructed for multistate series, parallel, “m out of n”, consecutive “m out of n: F”, series-parallel, parallel-series, series-“m out of k”, “mi out of li”-series, series-consecutive “m out of k: F” and consecutive “mi out of li: F”-series systems. The joint models are applied to determining safety characteristics of these systems related to their varying in time safety structures and their components safety characteristics. Under the assumption that the considered systems are exponential, the unconditional safety functions of these systems are determined. The proposed models and methods are applied to the safety analysis, evaluation and prediction of the one subsystem of the port grain transportation system related to varying in time their operation processes, structures and components safety parameters.

Opis:
The main aim of presented article is to present methodology how sophisticated products as compressor equipment can be considered and analysed as a complex technical system which consists of jointly operating components – a set of hardware, software, operational staff and documented information. In process modelling, these components are interacting in different processes of inputs, outputs, mechanisms (resources) or management. Based on the regulatory requirements for each component of the system, a key efficiency indicator can be identified. This allows to control the process and make appropriate decisions to improve the system. The application of the proposed methodology for the development and implementation of an integrated management system reduce the cost of resources and significantly improve the quality of the implementation of processes.

Wykorzystano zintegrowany ogólny model niezawodności złożonych systemów technicznych w zmiennych warunkach eksploatacyjnych, łączący wielostanowe podejście do analizy niezawodności systemów z modelem semi-markowskim ich procesu eksploatacji. Ten łączny model oraz programowanie liniowe zaproponowane są jako narzędzie do optymalizacji procesów eksploatacji złożonych systemów technicznych skutkującej maksymalizacją średnich czasów przebywania systemów w podzbiorach stanów niezawodnościowych.

Koncepcja uczenia się organizacyjnego (OL), mimo że ma już za sobą okres wzmożonego wzrostu popularności, nie straciła na aktualności i wadze. Mimo dość długiej historii badań nie istnieje spójna teoria uczenia się organizacyjnego. W pracy dokonano przeglądu czterech podejść do OL: behawiorystycznego, kognitywnego, konstruktywistycznego i społeczno-poznawczego. Ich porównanie z perspektywą nazwaną tu „złożonościową” (czyli związaną z traktowaniem organizacji jako systemu złożonego w rozumieniu teorii złożoności) wspiera tezę o rosnącej akceptacji złożoności w rozwoju teorii uczenia się organizacyjnego.
The organizational learning concept, although no longer in its hype phase, is still considered important and up-to-date. Despite a relatively long history, there is no common theory of Organizational Learning. This paper reviews four approaches to Organizational Learning: behaviourist, cognitive, constructivist, and social-cognitive. Their comparison with the complex (inspired by complexity science) perspective maintains the thesis that there is agrowing acceptance of complexity in the evolution of the Organizational Learning theory.

The paper explores the mathematical and computer modeling of complex technical systems related to their operation processes. The complex technical system with the reliability structure and components’ reliability parameters changing at the various operation states is defined. The selected system operation process parameters and the hypothetical distribution functions of the conditional sojourn times at the operation states are defined and identified. The reliability functions of the multistate system and components are introduced and their parameters are identified. The Monte Carlo simulation method is proposed to the complex system reliability evaluation. Moreover, the proposed theoretical and simulation tools are supported with the practical application to the multi-state port oil piping transportation system reliability analysis.

A stern tube sealing system installed on a sea vessel was used as an example of a complex technical system. Selected statistics of a ship’s operation losses were calculated. Selected, known-importance measures were presented and the authors’ own approach to cost-based, component-importance analysis was shown. The following measures were discussed: the operation-interruption cost index, the maintenance potential, the simulation-based maintenance index, and maintenance and operational costs. A description of factors influencing the importance of the technical system components was provided.

Opis:
System-based research remains an important yet usually outdated and internally contradictory approach in political science and international relations. Based on concepts borrowed from physiology, cybernetics, and general system theory, the system-based approach popularised in the 1960s was cast away as outdated and ill-focused. Despite those systems, the theory was developed in natural sciences, eventually creating a paradigm more applicable to domestic and international politics. The weakest element of past systems (like the one proposed by D. Easton) was that they did not allow for a sudden and catastrophic transformation and lacked emergence. This paper aims to present a model that would allow for the system’s ordinary and catastrophic transformation. The complex adaptive system features were defined using relevant literature on a paradigm of complexity. Connecting it with the propositions of D. Easton, R. Axelrod, and M. Cohen, as well as R. Jervis, such a model was constructed. The theoretical introduction is supplanted with a general case study of the early phases of the Arab Spring in Tunisia. The model mirrors the complex systems’ dynamics, considering the agent-structure problem.

Economic systems as complex systems are the source of many unconventional researches. The actual phenomena in complex systems have the non-scalability features and non-scalability does not exist without the power laws. This paper presents the occurrence of power series of rights and self-similarity in the distribution of national income in 2010, in terms of countries, the European Union and the Polish subregions. This means that one can study economic systems using tools of complex systems theory. This applies especially to the study of the mechanisms governing the system at the local level that generate global action.

The main component of the internal structure is the personnel of the company, which the authors regard as a dissipative system, and each employee as an open system that exchanges energy and entropy with the environment. The article suggests the entropy factors of labor productivity. Based on the equilibrium state of an employee as a system, it has been shown that labor productivity can be enhanced by the motivational factor of self-improvement for each member of the work community.

Opis:
Selected issues of component importance analysis for complex technical systems have been presented in this paper. A generic example of a complex technical system and selected statistics of operating losses have been described. A description and diagrams of both qualitative and quantitative importance analysis have also been included. The most significant problems facing complex technical system modelling have been pointed out. A multi-criteria system component importance analysis and the basic criteria for a system component quality evaluation have also been introduced. Some factors influencing the importance of the technical system’s components have also been described. Finally, the necessity of further developing importance analysis methods for machinery operation has been highlighted.

Opis:
W pracy przedstawiono model relacyjny, opracowany metodą analizy systemowej procesu zbioru i transportu jabłek w gospodarstwie sadowniczym. W wyniku odwzorowania izomorficznego model relacyjny tworzy para składająca się z 5 elementów i zbioru 10 relacji tworzących strukturę modelu, odzwierciedlającą najważniejsze procesy mające wpływ na czas zbioru i transportu jabłek. Sformułowany model relacyjny jest podstawą do opracowania modelu operacyjnego i jego logicznej weryfikacji.
The paper presents the relation model developed using the method involving system analysis of apple harvesting and transporting process in a fruit farm. As a result of isomorphic mapping, relation model is constituted by a pair consisting of 5 elements and a set of 10 relations forming model structure reflecting the most important processes affecting apple harvesting and transporting time. The formulated relation model provides the basis for operational model development and logical verification.

Opis:
W artykule przedstawiono propozycję sposobu wyznaczania niezawodności całkowitej i częściowej dla mobilnego modułu medycznego jako złożonego systemu technicznego. Dedykowanymi funkcjami takiego modułu są podjęcie rannego z pola walki (w wersji podstawowej) oraz zabezpieczenie utrzymania jego funkcji życiowych i wykonywania niezbędnych zabiegów medycznych (w wersji rozszerzonej). Prace nad opracowaniem koncepcji lub zaawansowaną budową takich modułów wykorzystujących bezzałogowe statki powietrzne jako drony transportowe są od kilku lat prowadzone przez wiele państw i firm lotniczych, m.in. agencję DARPA (USA) oraz ITWL (Polska). Pomimo że w Polsce nie ma jeszcze floty takich maszyn, to z doświadczeń w zarządzaniu statkami powietrznymi w Siłach Zbrojnych RP wynika potrzeba jednoczesnego zabezpieczenia eksploatacji takich modułów w informatyczny system wsparcia, wykorzystujący algorytmy i zależności matematyczne w zakresie wyznaczania niezawodności całkowitej i częściowej. Z uwagi na złożoność strukturalną mobilnego modułu medycznego (platforma nosiciela, napęd, wyposażenie awioniczne podstawowe i dodatkowe oraz wyposażenie medyczne podstawowe i rozszerzone) niezawodność całkowita i częściowa może być wyznaczana dla obiektu prostego (w wersji uproszczonej jako pełna niezawodność) lub systemu złożonego (jako całkowita i częściowa).
The article presents a proposal for a method to determine a total and partial reliability for a mobile medical module as a complex technical system. The dedicated functions of such a module are to evacuate the wounded from the battlefield (in the basic version) and to ensure the maintenance of his vital functions and the performance of necessary medical procedures (in the extended version). Work on developing the concept or advanced construction of such modules using unmanned aerial vehicles as transport drones has been carried out for several years by many countries and aviation companies, including: DARPA agency (USA) and AFIT (Poland). Even though there is no fleet of such machines in Poland yet, this comes from experience in managing aircraft in the Armed Forces RP results from the need to simultaneously secure the operation of such modules in an IT support system using algorithms and mathematical relationships in determining a total and partial reliability . Due to the structural complexity of the mobile medical module (carrier platform, drive, basic and additional avionics equipment and basic and extended medical equipment), a total and partial reliability can be determined for a simple object (in a simplified reliability version as full) or a complex system (as a total and partial reliability).
