Opis:
The narrative Gradov town written by A. Platonov attracted attention of many researchers in Soviet and Post Soviet periods. The most interesting approaches to interpretation are revealed in this work: widening of “bureaucracy” and “red tape” meaning; a problem of revolutionary tasks substituted by bureaucrats’ victories; a way of traditions’ using. Some unsuccessful attempts of philological analysis of the narrative were mentioned.

Opis:
Sovereignty is now a key concept in geographic scholarship. However, sustained geographic investigation of sovereignty commenced only in the 1990s, after the collapse of the Cold War order. Early, important contributions to the interrogation of sovereignty were historical, providing rigor in understanding the dialectical relationship between space and politics in the development of the state system. By the close of the twentieth century, however, historical complementarity in important geographic tracts on sovereignty, conditioned by new geopolitics of post-communism, gave way to diverging prognostications among academic geographers on the contemporary and future nature and salience of state sovereignty.

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:
In the paper, definitions and theoretical results on system operations process, multi-state system reliability, risk and availability modelling are illustrated by the example of their application to a bulk cargo transportation system operating in Gdynia Port Bulk Cargo Terminal. The bulk cargo transportation system is considered in varying in time operation conditions. The system reliability structure and its components reliability functions are changing in variable operation conditions. The system reliability structures are fixed with a high accuracy. Whereas, the input reliability characteristics of the bulk cargo transportation system components and the system operation process characteristics are not sufficiently exact because of the lack of statistical data. Anyway, the obtained evaluation may be a very useful example in simple and quick systems reliability characteristics evaluation, especially during the design and improving the transportation systems operating in ports.

Opis:
The study is focused on state defence management, in particular its political, strategic and legal-comparative aspects. The issue of managing the defence of the State has been presented from a systemic perspective as a separate system, being a part of a higher system and at the same time containing subordinate elements. Appropriate government documents of a conceptual nature and provisions in the common law on defence management were chosen as the subject for political-strategic and legislative legal analysis. The result of the analysis is a presentation of the key gaps and flaws in the legal solutions that may affect the functioning of the State defence management system in wartime1, in particular those related to the decision-making process of system components. In addition, an attempt was made to assess the implementation of security concepts adopted in Poland over the years, mainly in the field of managing national security and defence.

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

Basic concepts of the safety analysis of ageing multistate systems are introduced. The system components and the system multistate safety functions are defined. The mean values and variances of the multistate systems’ lifespans in the safety state subsets and the mean values of their lifespans in the particular safety states are defined. The multistate system risk function and the moment of exceeding the critical safety state are introduced. A series safety structure and a parallel-series safety structure of the multistate systems with ageing components are defined and their safety functions are determined. The multistate system safety models are applied to the prediction of safety characteristics of a maritime ferry.

Opis:
Considered in the paper complex technical system consists of a set of technical objects. These objects are the elements of the system. An object is treated as an element of a system if it is characterized by a specified set of features. Technical object features can be divided into two groups: additive and constitutive. Additive features are independent from relations inside the system, but constitutive ones depend on it. System features resulted from additive features of its elements can be defined as a sum of features of particular elements of the system. Unfortunately, in case of constitutive features of the system this way of defining is not proper. So, to identify the system itself, it is necessary to determine the unique set of the system features. Considering complex technical systems, it was stated that a state of a system is defined by instantaneous values of cardinal features of the system. So, the state of a system can be expressed in their features' space. But the set of the cardinal features of the system depend on the considered issue. In the field of machines maintenance and operation the technical systems can be analysed for different points of view. Therefore, the state of the system can be described in different features' spaces. In the paper different types of the system features' spaces are introduced. Thanks to the defined spaces application it is possible to create coherent description of all types of processes which are executed in a technical system during operation and maintenance phase.

Opis:
Nowadays, the main challenge in maintenance is to establish a dynamic maintenance strategy to significantly track and improve the performance measures of multi-state systems in terms of production, quality, security and even the environment. This paper presents a quantitative approach based on Dynamic Bayesian Network (DBN) to model and evaluate the maintenance of multi-state system and their functional dependencies. According to transition relationships between the system states modeled by the Markov process, a DBN model is established. The objective is to evaluate the reliability and the availability of the system with taking into account the impact of maintenance strategies (perfect repair and imperfect repair). Using the proposed approach, the dynamic probabilities of system states can be determined and the subsystems contributing to system failure can also be identified. A practical application is demonstrated by a case study of a blower system. Through the result of the diagnostic inference, to improve the performances of the blower, the critical components C, F, W, and P should be given more attention. The results indicate also that the perfect repair strategy can improve significantly the performances of the blower, while the imperfect repair strategy cannot degrade the performances in comparison to the perfect repair strategy. These results show the effectiveness of this approach in the context of a predictive evaluation process and in providing the opportunity to evaluate the impact of the choices made on the future measurement of systems performances. Finally, through diagnostic analysis, intervention management and maintenance planning are managed efficiently and optimally.

Opis:
The article concerns the assessment of the issue of immigration in Poland from a strategic perspective, in the context of the directions of counteracting possible threats generated by this phenomenon. The contemporary state has to deal with many dilemmas, among which undoubtedly is the phenomenon of immigration. It is not a problem if it is coming up against the needs of the state of immigration, such as filling shortages in the domestic labor market. However, as the experience of Western European countries shows, this phenomenon is not easily regulated, and therefore it is not difficult to generate risks instead of the planned benefits. In this context, one should remember about the situation of Western European countries with extensive migration networks on their territories. It concerns not only the problems they are currently facing in trying to regulate the inflow of immigrants, but also far from the expected effects of actions aimed at integrating the immigrant communities with the new state. In the Polish strategic documents for years, immigration has been defined as a phenomenon requiring special attention of the state. Subsequent security strategies in their assessments sustained this direction of perception, however, this did not result in a wider approach to the problem. It seems, however, that the state security system requires continuous improvement of threats monitoring mechanisms, mainly to precisely determine not only the risk of their occurrence and scope, but also to define methods of counteracting them.
