Opis:: This paper deals with the 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 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.

Opis:: 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.

Opis:: W artykule przedstawiono nowe praktyczne narzędzie do rozwiązania zagadnienia optymalizacji procesu eksploatacji i niezawodności złożonych systemów technicznych. 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.

Opis:: 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.
