Opis:
Purpose – The study aims to determine whether audited organizations experience differences between external audits and official controls. Design/methodology/approach – A survey among 100 organic food producers was conducted to explore differences regarding the usability of external audits and official controls. The survey was conducted in 2020 using the computer-assisted telephone interview (CATI) method supplemented by the computer-assisted web interview (CAWI) method. Organizations processing organic farming products in Poland were chosen for the study. Findings – Three primary benefits associated with external audits and official controls were identified, i.e. (1) enabling and initiating activities related to the improvement of the organization, (2) improving the financial performance of the organization and (3) enhancing credibility. For most organizations, the assessment of these features was at the same level for both external audits and official control. However, if these assessments differed, commercial audits were assessed at a higher level than official controls. Research limitations/implications – The study is limited to only one specific type of manufacturing organization and one European country. Originality/value – The literature review shows some conceptual differences between audits and official controls, but the results of this study show that the business environment does not perceive these differences as significant. Thus, the value of the study is reflected in the conclusion that both external audits and official controls are considered useful and credible approaches to monitoring the quality within the organization, which allows us to state that external evaluation is generally seen as an opportunity to improve the performance of the organization.

Opis:
Jeziora są zasobami wodnymi o istotnych funkcjach ekologicznych, rekreacyjnych i krajobrazowych, dlatego rozwój tych akwenów powinien uwzględniać ich wielofunkcyjny charakter i zachowanie wysokiej jakości wód. Jeziora sklasyfikowane jako wody płynące stanowią własność Skarbu Państwa, a gospodarowanie nimi należy do obowiązków podmiotów publicznych. Wyniki dotychczasowych kontroli NIK wskazują na liczne nieprawidłowości w tym obszarze. Do największych problemów należy ograniczanie dostępu do linii brzegowej przez właścicieli nieruchomości przylegających do jezior oraz samowolna budowa pomostów.
Lakes are water resources with significant ecological, recreational and scenic values, that is why their development should consider their multifunctional nature and preservation of high quality of water. Lakes, which are classified as flowing waters, belong to the State Treasury, and their management lies with public entities. The audits that NIK conducted to date in the area indicated numerous irregularities. These include restricted access to the shoreline due to owners of estates adjacent to lakes, or illegally constructed piers. The latest audit of NIK related to the management of lakes that constitute public waters was conducted in 2022, on NIK’s own initiative, in order to assess how the competent public administration bodies performed their tasks in the area. The audit comprised the Ministry of Infrastructure and 16 organisational units of the Polish Waters State Water Holding (Polish Państwowe Gospodarstwo Wodne Wody Polskie, PGW WP), i.e. the National Board of Water Management (Polish KrajowyZarząd Gospodarki Wodnej, KZGW), five regional water management boards, five boards of drainage basins and five water supervisory boards. NIK assessed the activities of these bodies, as well as the supervision of public lakes management. The following issues were audited: performance of owner’s responsibilities by the State Treasury with regard to lakes, including sales of lands, execution of the ban on fencing that prevents access to lakes, and control of water management.

Opis:
The study is devoted to an attempt to determine whether the analyses carried out at the level of the philosophy, theory and analysis and synthesis of criminal law, as well as the approaches presented in various criminological theories can be used in debates about the goals and functions of modern criminal law. The analyses carried out are based on the reconstruction of the current state of criminal law, dominated in many countries by penal populism. The coincidence of the repressiveness characteristic of the populist approach subordinated to the implementation of the concept of extreme deterrence, with the position of the legal elite as to the goals and functions of criminal law, illustrates the state of tensions and crises in which contemporary repressive law has found itself. The image of the public debate, characterized by the unambiguity of positions combined with the lack of perceptual openness to the views presented by the proponents of opposing approaches, provides a premise for the search for rational and verifiable arguments in disputes over the shape of criminal law. Given the limitations of the analysis and synthesis of criminal law in the sphere of disputes about values, an anthropological vision and a model of social structure make it reasonable to search for premises that order the debate about criminal law on other levels. In this regard, the study presents systemic approaches presented in the philosophy of criminal law combined with an attempt to justify that, in fact, complementary elements can be seen in them. Complementing the philosophical perspective is the plane of criminal law theory, on which one can also find elements that are part of the universal approach to repressive law. Adding to this picture of modern criminological theories, the study presents the thesis that modern criminal law serves multiple, sometimes opposing functions justified by reference to other assumptions and models of social structure. The multiple functions of modern criminal law make it unreasonable to refer to the dichotomy capturing alternatively the functions and goals of criminal law either as an instrument for protection of socially valuable values or as a tool of management by repression. The text seeks to justify the position that modern criminal law performs, in part, both functions indicated above. At the same time, there are opportunities to rationally limit the use of criminal law instrumentally as a tool of management by repression in the interest of power and certain social groups. The science of criminal law, encompassing the following planes: theoretical and philosophical, can be a plane that provides premises and arguments to help resolve contemporary dilemmas. In particular, it seems that the approaches presented in the science of criminal law and criminology are not so much of an opposing and radically competitive nature, but are in fact harmonizing, containing a number of complementary elements in a complex set of assumptions and claims that make up a holistic approach to the criminal law system.

Zreformowany standard ISSAI 140 , będący częścią systemu zasad, standardów i wytycznych Międzynarodowej Organizacji Najwyższych Organów Kontroli (INTOSAI) , wejdzie w życie 1 stycznia 2025 roku. Dokument skupia się na zarządzaniu jakością w najwyższych organach kontroli (NOK). Celem artykułu jest przybliżenie nowych wytycznych oraz próba ich krytycznej oceny z perspektywy poprzednich reguł, jak również zmian postulowanych, a niewprowadzonych.
Revised ISSAI 140, which is part of the system of principles, standards and guidance (pronouncements) of the International Organisation of Supreme Audit Institutions – INTOSAI, will enter into force on 1 January 2025. It is an important pronouncement since it focuses on quality management in Supreme Audit Institutions (SAIs). It was first introduced in 2010 as ISSAI 40, then it was included in the reformed INTOSAI Framework of Professional Pronouncements (IFPP) and renamed ISSAI 140 with editorial changes on 2019, and later it had to be revised following the Strategic Development Plan 2020–2022 (Component 2). On one hand, needs were postulated to introduce clear consistent and adequate standards not only for general quality control, but for direct quality management, considering various SAI structures and unification of terminology. On the other hand, the reform was necessary since ISQC–1, developed by the International Auditing and Assurance Standards Board (IAASB), mainly for the needs of the private sector, was updated in December 2020. The objective of the article it to present the new guidance of INTOSAI related to quality management. The author also attempts to make a critical assessment of the document, from the perspective of the previous principles, as well as the changes that were postulated but have not been introduced.

Opis:
Over the past few years, a significant increase in network traffic volumes has been observed. The ever growing bandwidth demands mean that a reliable and optimum service level needs to be ensured in communication systems for specific traffic categories. Optimal allocation and use of resources may be achieved through the use of call admission control (CAC) mechanisms implemented in network systems. The resource reservation mechanism and the threshold mechanism are two of the most popular CAC methods. In the reservation mechanisms, a certain number of resources is reserved for selected (predefined) services only. In the case of threshold mechanisms, the number of resources allocated to individual traffic classes depends on the network load. This article discusses the results of simulations verifying the impact of applied CAC mechanisms on the traffic characteristics in elastic optical network (EON) nodes with a Clos structure. Loss probability results obtained with the use of the simulator are presented as well.

Opis:
Electric energy systems need constant modernization and updating to solve such problems as distributed management, self-sealing, improving the quality of electricity, demand management, and integration of renewable energy systems. Currently, energy systems need advanced and intelligent technologies to perform various system-level tasks. The purpose of this research is to analyze the existing control systems of electric energy systems, as well as to consider the possibility of using multi-agent systems to control electric energy systems. To achieve the aim of the research, the following scientific approaches were implemented: method of direct research, experimental method, questioning, comparative method, analysis method, and method of observation. The primary value of the research is in the novelty of the work and the fact, that functional components in multi-agent systems act as independent agents, which can interact with each other through a message communication system. This provides a simple connection between the components, which can benefit complex systems designed for an intelligent network. The intelligent network provides an efficient energy management system, and the modernization of the existing power system using a multi-agent system provides solutions to many problems. The best implementation of a multi-agent system can be achieved through the employment of fast and protected communication protocols. The authors of the research have conducted research and presented key statistical data on electricity usage in Kazakhstan over the past few years. The practical significance of the research is determined by the applied results, and their scientific significance, which is conditioned upon the use of deep, modern mathematical results and the development of an optimal control system. This research is a part of a universal model and optimal system of emergency quick response, conducting a quick preliminary prognosis as well as ensuring more lasting planning in electricity consumption.

Opis:
Today’s electricity management mainly focuses on smart grid implementation for better power utilization. Supply-demand balancing, and high operating costs are still considered the most challenging factors in the smart grid. To overcome this drawback, a Markov fuzzy real-time demand-side manager (MARKOV FRDSM) is proposed to reduce the operating cost of the smart grid system and maintain a supply-demand balance in an uncertain environment. In addition, a non-linear model predictive controller (NMPC) is designed to give a global solution to the non-linear optimization problem with real-time requirements based on the uncertainties over the forecasted load demands and current load status. The proposed MARKOV FRDSM provides a faster scale power allocation concerning fuzzy optimization and deals with uncertainties and imprecision. The implemented results show the proposed MARKOV FRDSM model reduces the cost of operation of the microgrid by 1.95%, 1.16%, and 1.09% than the existing method such as differential evolution and real coded genetic algorithm and maintains the supply-demand balance in the microgrid.

Opis:
Design and construction of container ships follow consolidated requirements, with standard consideration of fire management. Indeed, cargo fires can have important consequence on crewmembers and cargoes, as well as impacting coastal zone and marine environment. Innovative strategies include prevention of events and mitigation of consequences. Digital solutions, providing with situational pictures onboard and around the vessel are fundamental for new fire management solutions, seamless and integrated into the vessel IT infrastructure, according to IMO regulations and the recent EMSA CARGOSAFE Report. The assessment of these solutions requires theoretical evaluation, validation activities in simulated environment and demonstration activities in real environments, with use cases to prove feasibility and benefits. This paper, after a review of traditional preventing and mitigating solutions against fire and an analysis of container ships fires, proposes applicable innovative technologies and operational measures, emerging problems for their potential implementation and requirements for virtual and real tests design.

Opis:
Purpose: The purpose of this article is to present a research report on a system dynamics simulation modeling and experimenting of bullwhip effect (BWE) to examine effectiveness of some selected inventory control policies with down- and upstream information flow in a Beer Distribution Game (BDG) of a supply chain structure. Design/methodology/approach: The impact of systems’ structures and decision making policies in supply chains or logistics systems are measured and analyzed by an application of systems thinking paradigms and approaches. Particularly, the continuous simulation modeling approach with systems thinking Iceberg model metaphor, allowing to focus on strategic aspects of management with some recommendation to design better structures and decision making policies are taken. For the bullwhip effect analysis of a supply chain example (based on BDG model), a System Dynamics (SD) continuous simulation modeling method with some proposals in order to analyze feedback loop dominance are undertaken to explain supply chain behaviors and to make some sensitivity analysis for decision making (inventory control) policies. Findings: The research findings outline the impact of cause - effect relations, feedback loops polarities, and decision making policies to particular behaviors of the BDG supply chain. Research limitations/implications: Because of complexity of heuristic methods for feedback loop dominance analysis only simple approach was applied (LPD), and some selected scenario for simulation experiments were undertaken resulting in limited conclusions. Practical implications: The conclusions of the research draw some practical recommendations for a design of information sharing system and an effectiveness of some inventory control policies to be applied in supply chains. Social implications: One of the systems thinking elements in practical management is an influence to mental models of managers and decision makers. Managers in supply chain systems particularly need some recommendations to avoid bullwhip effect negative impacts. Additionally, managers and also scholars still call for more research to investigate the design and decision making in supply chains, therefore systems thinking simulation research can bridge the gap between traditional operations research and management with other approaches to provide insight into supply-chain dynamics and deliver impactful suggestions to managers. Originality/value: The paper gives a concept of supply chain dynamic analysis by an application of Iceberg model systems thinking metaphor, feedback loop dominance analysis, and a measurement of some selected inventory control policies effectiveness.

Opis:
Based on China’s resource endowment and coal mine disaster statistics, it has been found that there are many deficiencies in the management of disasters and risks in mining areas in China. Therefore, to scientifically and effectively manage mining areas, based on the theory of internal control, this paper systematically analyzes the risks of mining areas in the context of various factors and relevant suggestions. From the occurrence of mine risk to the occurrence of damage, the importance of risk management is highlighted. In accordance with the five selection principles of evaluation indicators (goal principle, comprehensiveness principle, scientificity principle, timeliness principle and focus principle) as well as the five elements of internal control (control environment, risk assessment, control activities, information and communication and supervision), a mining area risk management framework of human-machine-environment-management – disturbance is constructed, and twenty-seven secondary risk indicators are divided. The criteria for determining the risk level and the risk response process have been established, and a more systematic and accurate mine risk management system under the theory of internal control has been formed. Finally, based on four key technologies, a dual prevention and control mechanism is formed around the system risk and job risk management system. This provides new methods and ideas for the prevention and control of coal mine safety risks and the containment of disasters and accidents.
Na podstawie chińskich zasobów i statystyk dotyczących katastrof w kopalniach węgla stwierdzono, że istnieje wiele niedociągnięć w zarządzaniu katastrofami i ryzykiem na obszarach górniczych w Chinach. Dlatego, aby naukowo i efektywnie zarządzać obszarami górniczymi, w oparciu o teorię kontroli wewnętrznej, w artykule systematycznie analizuje się ryzyko obszarów górniczych pod kątem różnych czynników i odpowiednich sugestii. Od wystąpienia ryzyka górniczego do wystąpienia szkód podkreśla się znaczenie zarządzania ryzykiem. Zgodnie z pięcioma zasadami wyboru wskaźników oceny: zasadą celu, zasadą kompleksowości, zasadą naukowości, zasadą terminowości i zasadą ukierunkowania, a także pięcioma elementami kontroli wewnętrznej: środowiskiem kontroli, oceną ryzyka, działaniami kontrolnymi, informacją i komunikacją oraz nadzorem, skonstruowano ramy zarządzania ryzykiem w obszarze górniczym w zakresie zakłóceń w zarządzaniu ludźmi, maszynami i środowiskiem oraz podzielono 27 drugorzędnych wskaźników ryzyka. Ustalono kryteria określania poziomu ryzyka i proces reagowania na ryzyko, a także stworzono bardziej systematyczny i dokładny system zarządzania ryzykiem kopalnianym w ramach teorii kontroli wewnętrznej. Wreszcie, w oparciu o cztery kluczowe technologie, stworzono podwójny mechanizm zapobiegania i kontroli ryzyka systemowego i systemu zarządzania ryzykiem zawodowym. Zapewnia to nowe metody i pomysły w zakresie zapobiegania i kontroli zagrożeń bezpieczeństwa w kopalniach węgla oraz ograniczania katastrof i wypadków.

Opis:
The aim of this article is to indicate the importance of introducing management control in aspects of risk management. To this end, the article reviews legal acts and literature on the issue of management control. The article indicates the practical application of legislation and recommended standards from the perspective of risk management in healthcare entities. This article looks to discuss management control in healthcare entities. The Public Finance Act introduced in 2009 in Poland obliged all units of the public finance sector to introduce management control mechanisms in order to support the implementation of set goals and tasks in a lawful, effective, economical and timely manner. This proved helpful with regard healthcare entities, particularly when management control is properly applied and meets the assumed important goals. Management control standards define the basic requirements for management control. Management control standards are important in the implementation of assumptions; and constitute a set of guidelines that help the manager of the unit to create optimal solutions. The main objective of the standards is to promote the implementation of a coherent and uniform model of management control in the public finance sector, which will be compliant with international standards in this regard; taking into account the specific tasks of the unit that implements it and the conditions in which the unit operates. Taking into account the complexity of procedures and the huge amount of organizational work in healthcare entities, management control is all the more important. Management control is an important process for the proper functioning of healthcare entities. It helps eliminate or minimize risks, including the important risk of medical malpractice. Implemented management control standards will be shown to eliminate or reduce risks associated with the operation of a medical entity, including risks related to medical malpractice.
Celem artykułu jest wskazanie ważności wprowadzenia kontroli zarządczej w aspekcje zarządzania ryzykiem, zastosowano metodę przeglądu aktów prawnych i literatury z zagadnienia kontroli zarządczej. Artykuł wskazuje praktyczne zastosowanie ustawy i zalecanych standardów z punktu wiedzenia zarządzania ryzykiem w podmiotach leczniczych. Wprowadzona w 2009 roku ustawa o finansach publicznych w Polsce zobligowała wszystkie jednostki sektora finansów publicznych do wprowadzenia mechanizmów kontroli zarządczej, która ma wspomóc realizację wyznaczonych celów i zadań w sposób zgodny z prawem, efektywny, oszczędny oraz terminowy. Jest ona również pomocna w pomiotach leczniczych – jeśli kontrola zarządcza jest odpowiednio stosowana, spełnia zakładane ważne cele. Standardy kontroli zarządczej określają podstawowe wymagania odnoszące się do kontroli zarządczej. Standardy kontroli zarządczej są istotne w realizacji założeń i stanowią zbiór wytycznych, które pomagają kierownikowi jednostki w tworzeniu optymalnych rozwiązań. Głównym celem standardów jest promowanie wdrażania w sektorze finansów publicznych spójnego i jednolitego modelu kontroli zarządczej, który zgodny będzie z międzynarodowymi standardami w tym zakresie, z uwzględnieniem specyficznych zadań jednostki, która ją wdraża oraz warunków, w których jednostka działa. Uwzględniając złożoność procedur i ogromną ilość prac organizacyjnych w podmiotach leczniczych, tym bardziej ważna jest kontrola zarządcza. Jest ona istotnym procesem dla prawidłowego funkcjonowania podmiotów leczniczych. Wdrożone standardy kontroli zarządczej eliminują lub zmniejszają ryzyka towarzyszące prowadzeniu działaności podmiotu medycznego, w tym również ważne ryzyko związane z błędem lekarskim.

Opis:
In recent years, due to the increasing number of renewable energy sources, which are characterised by the stochastic nature of the generated power, interest in energy storage has increased. Commercial installations use simple deterministic methods with low economic efficiency. Hence, there is a need for intelligent algorithms that combine technical and economic aspects. Methods based on computational intelligence (CI) could be a solution. The paper presents an algorithm for optimising power flow in microgrids by using computational intelligence methods. This approach ensures technical and economic efficiency by combining multiple aspects in a single objective function with minimal numerical complexity. It is scalable to any industrial or residential microgrid system. The method uses load and generation forecasts at any time horizon and resolution and the actual specifications of the energy storage systems, ensuring that technological constraints are maintained. The paper presents selected calculation results for a typical residential microgrid supplied with a photovoltaic system. The results of the proposed algorithm are compared with the outcomes provided by a deterministic management system. The computational intelligence method allows the objective function to be adjusted to find the optimal balance of economic and technical effects. Initially, the authors tested the invented algorithm for technical effects, minimising the power exchanged with the distribution system. The application of the algorithm resulted in financial losses, €12.78 for the deterministic algorithm and €8.68 for the algorithm using computational intelligence. Thus, in the next step, a control favouring economic goals was checked using the CI algorithm. The case where charging the storage system from the grid was disabled resulted in a financial benefit of €10.02, whereas when the storage system was allowed to charge from the grid, €437.69. Despite the financial benefits, the application of the algorithm resulted in up to 1560 discharge cycles. Thus, a new unconventional case was considered in which technical and economic objectives were combined, leading to an optimum benefit of €255.17 with 560 discharge cycles per year. Further research of the algorithm will focus on the development of a fitness function coupled to the power system model.

Opis:
Railways deliver a safe and sustainable form of transport and are typically pointed as one the safest form of transportation. Nevertheless, train accidents still happen, and when they happen, the consequences concern serious fatalities and injuries. Since every case is unique, the most frequent causes of train accidents are mechanical derailments, failures, as well as human errors and ignorance. In order to mitigate the risks posed by both physical and human related factors, various technological advancements have been designed and implemented. Among many existing Train Control and Monitoring Systems (TCMS), one can observe that recently developed artificial intelligence (AI) methods are also considered to be integrated part of the modern TCMS solutions. Following recent AI improvements and trends, in this paper we aim to present and discuss our newly developed TCMS system. In particular, both the system architecture and features are described along with the expected benefits of its implementation.
