Opis:
Purpose: of this study is to address the issue of maintenance work in the accommodation sector. The development of the means of transport, the increase in income level and the increase in comfort level create a desire for people to travel more. In the travels to different cities, accommodation facilities such as hotels, holiday villages and apartments are used. Customer satisfaction is very important for the accommodation facilities. In order to ensure customer satisfaction, the services provided should not be interrupted and all machinery and equipment must be in working condition. To ensure this, it is very important to carry out maintenance work on the plants and devices. Therefore, the establishment of a maintenance management system in accommodation facilities is very important and it is necessary to carry out maintenance work. In this context, different maintenance methods are applied in accommodation facilities. In this study, maintenance of accommodation facilities is discussed. Design/methodology/approach: Within the scope of the study, maintenance and maintenance management in accommodation facilities are discussed. The maintenance principles of accommodation facilities are discussed in detail. The places where maintenance services are conducted in accommodation facilities and maintenance methods are discussed. Findings: This study shows that that the implementation of maintenance management system will increase customer satisfaction. It has been evaluated that maintenance can be successful not only by maintenance personnel but also with the participation of all plant employees. Research limitations/implications: In order to see the importance of maintenance in accommodation facilities, it will be appropriate to compare the hotels with the maintenance management system applied and the hotels that are not implemented in terms of customer satisfaction and maintenance expenses. For the future studies, the maintenance management system in hotels can be examined in detail. Practical implications: Expanding the maintenance management practices in accommodation facilities will increase the capacity utilization rate of the hotels and increase customer satisfaction. Originality/value: In the field of maintenance, detailed studies have been carried out in the manufacturing sector for a long time and have been examined in detail. However, work in this area is quite limited, especially in accommodation facilities and hotels. In this study, the subject of accommodation facilities and maintenance of hotels was discussed in detail.

Opis:
Maritime safety involves minimizing error in all aspects of the marine system. Human error has received much importance, being responsible for about 80% of the maritime accident worldwide. Currently, more attention has been focused to reduce human error in marine engine maintenance. On-board marine engine maintenance activities are often complex, where seafarers conduct maintenance activities in various marine environmental (i.e. extreme weather, ship motions, noise, and vibration) and operational (i.e. work overload and stress) conditions. These environmental and operational conditions, in combination with generic human error tendencies, results in innumerable forms of error. There are numerous accidents that happened due to the human error during the maintenance activities of a marine engine. The most severe human error results in accidents due to is a loss of life. Moreover, there are other consequences too such as delaying the productivity of marine operations which results in the financial loss. This study reviews methods that are currently available for identifying, reporting and managing human error in marine engine maintenance. As a basis for this discussion, authors provide an overview of approaches for investigating human error, and a description of marine engine maintenance activities and environmental and operational characteristics.

Opis:
Maintenance is an important way to ensure the best performance of repairable systems. This paper considers how to reduce system maintenance cost while ensuring consistent system performance. Due to budget constraints, preventive maintenance (PM) can be done on only some of the system components. Also, different selections of components to be maintained can have markedly different effects on system performance. On the basis of the above issues, this paper proposes an importance-based maintenance priority (IBMP) model to guide the selection of PM components. Then the model is extended to find the degree of correlation between two components to be maintained and a joint importance-based maintenance priority (JIBMP) model to guide the selection of opportunistic maintenance (OM) components is proposed. Also, optimization strategies under various conditions are proposed. Finally, a case of 2H2E architecture is used to demonstrate the proposed method. The results show that generators in the 2E layout have the highest maintenance priority, which further explains the difference in the importance of each component in PM.

Opis:
Artykuł omawia niemiecką monografię poświęconą prawu alimentacyjnemu Unterhaltsprozess (Eschenbruch, Wolters Kluwer 2021). Autor poszukuje wielowymiarowości alimentacji zarówno w wymiarze krajowym, jak i międzynarodowym, a ocena uwzględnia interdyscyplinarny i transgraniczny charakter tej problematyki, która łączy prawo rodzinne z prawem publicznym, socjalnym, procesowym, podatkowym, europejskim oraz prywatnym międzynarodowym. W tych ramach omówiono zakres i strukturę monografii, która nie ogranicza się do przestawienia aktualnego stanu prawnego, ale dokumentuje również ewolucję prawa alimentacyjnego, wytycza nowe kierunki rozwoju, a także zawiera propozycje zmian legislacyjnych. Autor wskazuje cechy wyróżniające ocenianą monografię od innych opracowań dostępnych na rynku podkreślając wyjątkowo szeroką analizę orzecznictwa sądów apelacyjnych. Szerszej analizie i ocenie poddano zagadnienia związane z pieczą naprzemienną, alimentacją pomałżeńską, świadczeniami socjalnymi, pozycją prawną ojca biologicznego oraz alimentacją transgraniczną. Z perspektywy prawnoporównawczej zauważono natomiast skromne odniesienia do prawa obcego, które warto poszerzyć i usystematyzować. Oceny monografii dokonano zarówno pod względem naukowym jak i praktycznym. Szczególną uwagę zwrócono przy tym na możliwość wykorzystania niemieckich regulacji i doświadczenia w polskim porządku prawnym.
This article reviews the German book on the maintenance law Unterhaltsprozess (Eschenbruch, Wolters Kluwer 2021). The author searches for the multidimensionality of maintenance, both in the national and international dimension, and the assessment takes into account the interdisciplinary and the cross-border nature of this issue, which combines family law with public, social, procedural, tax, European, and private international law. Within this framework, the scope and structure of the monograph is discussed, which is not limited to presenting the current legal regulation, but also documents the evolution of the maintenance law, sets new directions for development, and includes proposals for legislative changes. The author indicates features that distinguish the reviewed monograph from other studies available on the market, emphasizing the exceptionally broad analysis of the jurisprudence of courts of appeal. The issues related to joint custody, post-marital maintenance, social benefits, the legal position of the biological father, and cross-border maintenance, were subject to a broader analysis and assessment. From the comparative legal perspective, however, attention is drawn to the modest references to foreign law, which call for further expansion and systematization. The monograph is assessed both in terms of research and practice. Particular attention is paid to the possibility of using German regulations and experience in the Polish legal system.

Opis:
Maintenance is a key manufacturing function that contributes to a company’s productivity, profitability and sustainability. Unfortunately, many aspects of the contribution of maintenance to sustainability in manufacturing remain unexplored, and many enterprises are not yet ready to assess the maintenance impacts on their sustainability. Maturity models are useful tools for assessing maintenance practices; however, no maintenance maturity model that allows the evaluation of the contribution of maintenance to sustainable performance was found in literature. This paper proposes a model for assessing the maturity and sustainability of maintenance processes. The model outputs are: a measure of the maintenance and sustainability maturity level; recommendations for improvement to undertake to enhance maintenance maturity and, thus, meet sustainability standards. The model was applied in three manufacturing enterprises: the calculation of their maintenance maturity and sustainability indices made the maintenance stakeholders more aware of the need to implement effective strategies for more sustainable maintenance performance.

Opis:
Many authors have highlighted the importance of physical assets maintenance management in relation to resilience engineering, especially for systems operating under significant uncertainty. Thus, the authors presented a new approach to system maintenance based on resilience concept implementation. They introduced Maintenance Support Potentials (MSP) as a measure of an organization's maintenance support capacity. Moreover, based on the MSP definition, they developed a fuzzy-based organization's maintenance support potential level assessment method. The proposed approach takes into account two main MSP parameters – potential readiness level and process regency. It followed four main steps, including organization's MSP identification/evaluation, MSP weights assessment, Maintenance Support Capacity assessment, and final reasoning. A case study of a global manufacturer from the automotive industry is presented to illustrate the method's applicability. The authors also indicated further research directions to optimize the maintenance strategy based on Resilience-Based Maintenance concept.

Opis:
This paper deals with the maintenance cost of deteriorating systems. Two maintenance strategies are studied: age-replacement and condition-based maintenance. To compare these two policies, degradation models are used: these models characterize the degradation level but also the system time-to-failure. In order to compute the optimal condition-based maintenance cost, we suppose that the main influencing sources are the preventive threshold, the inspection frequency and the inspection cost. Numerical examples illustrate the maintenance cost computation and compare the optimal costs of both policies.

Opis:
Koncepcja "e-maintenance" (pol. e-obsługiwanie, e-utrzymanie ruchu) jest najnowszym osiągnięciem na polu zarządzania utrzymaniem ruchu obiektów technicznych. Zapewniając stałe monitorowanie stanu maszyny i zarządzanie nimi przez Internet powoduje sprzężenie zwrotne miedzy systemami operacyjnymi produkcji i eksploatacji. Zbiór i dynamiczna wymiana informacji eksploatacyjnych w czasie rzeczywistym tworzy silną strukturę pozwalającą na budowanie i wykorzystanie wiedzy o obiektach technicznych i procesach produkcyjnych. To stwarza wielkie możliwości dla podejmowania korzystnych ekonomicznie decyzji. W artykule przedstawiono zasadę budowy, zalety i ograniczenia koncepcji "emaintenance", przy uwzględnieniu aktualnych trendów informatycznych, telekomunikacyjnych, zarządzania, ochrony środowiska i zrównoważonego rozwoju oraz aktualny stan systemu utrzymania ruchu maszyn i pojazdów rolniczych opartego na koncepcji "e-maintenance". Przeprowadzono analizę korzyści i ograniczeń wynikających z wprowadzenia systemu, zaproponowano jego popularyzację w ramach dydaktyki na uczelniach rolniczych.
The concept of "e-maintenance" is the newest success in the field of traffic maintenance management of technical facilities. Ensuring constant monitoring of the machine condition and managing it through Internet results in a feedback between operational systems of production and exploitation. Collection and dynamic exchange of exploitation information in actual time forms a strong structure which allows to build and use knowledge on technical facilities and production processes. It creates great possibilities for taking economically advantageous decisions. The rule of construction, good points and limitations of the "e-maintenance"concept were presented in the article at consideration of present information, telecommunication, management, environment protection and sustainable development trends as well as the present condition of the traffic maintenance system of farm machines and vehicles based on the "e-maintenance" concept. Analysis of advantages and limitations resulting from introduction of the system was carried out; its popularization within didactics on agricultural universities was suggested.

Opis:
In the paper, the methodology of optimization of planned preventive maintenance is proposed, which is based on the utilization of data obtained from a maintenance information system - adjusting the database structure, collection and processing of data. The data processing algorithm is based on the application of theory of replacement and its modification for the given problem. The core principle of the algorithm is the minimization of costs of maintenance and operation of production equipment. The algorithm can be either used as a separate tool or integrated into the computer maintenance management system as a complementary module. Therefore it enables to optimize the intervals of various levels of planned preventive maintenance of most of the production equipment in a company. A practical example of application of such algorithm is presented in the end of the paper.
W niniejszej pracy zaproponowano metodologię optymalizacji planowych prac konserwacyjnych opartą na wykorzystaniu danych pozyskanych z systemu informacji eksploatacyjnej - dopasowaniu struktury bazy danych, sposobu jej gromadzenia i przetwarzania. Algorytm przetwarzania danych opiera się na zastosowaniu teorii wymiany i jej modyfikacji dla danego problemu. Centralną zasadą algorytmu jest minimalizacja kosztów utrzymania i użytkowania sprzętu produkcyjnego. Algorytm ten może być używany jako oddzielne narzędzie lub może być integrowany z systemem komputerowego zarządzania eksploatacją i utrzymaniem ruchu jako moduł uzupełniający. Tym samym pozwala on na optymalizację przerw poświęconych różnego zakresu planowym pracom konserwacyjnym większości sprzętu produkcyjnego w przedsiębiorstwie. Przykład praktycznego zastosowania takiego algorytmu przedstawiono w końcowej części pracy.

However, the existing reliability models established using stochastic processes only consider the internal degradation process, and do not fully consider the impact of external random shocks on their reliability modeling. Furthermore, the existing theory of importance does not consider the actual factors of maintenance cost. In this paper, based on the reliability modeling of random processes, the degradation rate under the influence of random shocks is introduced into the time scale function to solve the impact of random shocks on product reliability, and two cost importance measures are proposed to guide the maintenance selection of the components under limited resources in the system. Finally, a subsystem of an aircraft hydraulic system is analyzed to verify the proposed method’s performance.

Opis:
For industrial and military applications, a sequence of missions would be performed with a limited break between two adjacent missions. To improve the system reliability, selective maintenance may be performed on components during the break. Most studies on selective maintenance generally use minimal repair and replacement as maintenance actions while break duration is assumed to be deterministic. However, in practical engineering, many maintenance actions are imperfect maintenance, and the break duration is stochastic due to environmental and other factors. Therefore, a selective maintenance optimization model is proposed with imperfect maintenance for stochastic break duration. The model is aimed to maximize the reliability of system successfully completing the next mission. The reinforcement learning(RL) method is applied to optimally select maintenance actions for selected components. The proposed model and the advantages of the RL are verified by three case studies verify.

Opis:
In future, offshore wind turbines may be consider a crucial part in the supply of energy. Maintenance processes are directed to attain a safe and reliable operation of offshore machines and wind turbines. In this paper, an opportunistic maintenance strategy for offshore wind turbine is proposed, considering imperfect maintenance and the preventive maintenance durations. Reliability Centric Maintenance serves as a proactive tactic to operations and maintenance by inhibiting the possible reasons of poor performance and controlling failures. Other components can implement the opportunistic preventive maintenances if one component has reached its reliability threshold. According to the rolling horizon approach, it is of great importance to update the maintenance planning for the sake of the short-term information. By figuring out the best combination, the maintenance schedule in the mission time has been finally determined. Failure information are obtained from previous studies to accomplish the calculations. The outcomes indicate that the maintenance cost has been dramatically reduced through the application of opportunistic maintenance.

Opis:
Automatically controlled hydraulic tension systems adjust the tension force of a conveyor belt under different working conditions. Failures of an automatically controlled hydraulic tension system influence the performance of conveyor belts. At present, the maintenance of automatically controlled hydraulic tension systems mainly considers the replacement of components when failures occur. Considering the maintenance cost and downtime, it is impossible to repair all the failed components to improve the hydraulic tension system. One of the key problems is selecting the most valuable components for preventive maintenance. In this paper, preventive maintenance for multiple components in a hydraulic tension system is analyzed. An index is proposed to select more reliable preventive maintenance components to replace the original ones. A case study is given to demonstrate the proposed method. When the cost budget increases, there are three different variations in the number of components for selective preventive maintenance (SPM).

Opis:
Employers are under a legal obligation to provide employees with safe and hygienic conditions of work. These conditions are created by environmental factors that depend on the specifics of the enterprise, production technology and used machinery and equipment. A large number of the risks to which employees are exposed is associated with the use of machinery, equipment and working tools (as confirmed by Statistics Poland). Numerous manufacturing companies increasingly use the practice of involving operators, independently from the maintenance department, in the upkeep and maintenance of machinery and equipment in order to increase efficiency. These activities are undertaken within the scope of Autonomous Maintenance (AM), which is one of the essential elements underpinning the TPM system. The activities performed by operators within AM, such as daily inspections, lubrication or simple repairs, reduce the number of machinery breakdowns. Nonetheless, they could be a potential source of risk for employees. Companies applying the traditional division of tasks entrust the performance of such activities to qualified maintenance staff, so the proper identification of risks that takes into account the specificity of the activities performed by operators and the provision of training in the safe organization of work represent a significant feature of safety improvement. Enterprises may adopt multiple solutions in this regard, including the tools and techniques of the concept of Lean Manufacturing.

Opis:
The article aims to present practical methods for prioritising the activities of maintenance departments based on the Pareto analysis and the failure risk analysis. Based on the collected data on the number of observed failures and their removal times, commonly known reliability indicators were determined, which were then used to estimate the probabilities and consequences of failures in terms of the risk of loss of production continuity. Based on commonly collected failure data, the developed methods allow proposing to the maintenance departments the sequence of maintenance and repair work to be undertaken in terms of minimising the risk of failure. Risk analysis is somewhat commonly used in the practice of maintenance departments (e.g. RBI, FMEA, ETA, FTE, HIRA). The added value of this work is the use of reliability indicators for estimating the values of risk components, i.e., probability and consequences. The method was developed on the basis of operational data collected in one of the plants of the dairy cooperative and, after assessing the effects of its implementation, it was implemented in other enterprises of the cooperative.

Opis:
Maintenance involves a large amount of data management. Although many tools, strategies, and systems, have been developed to organize the maintenance information resources, SMEs have not found the same benefits as large companies due to their inherent characteristics and, above all, the maturity level of the maintenance department. Maturity models are useful tools for assessing the maturity of maintenance information practices; however, existing models are not suitable for any type of business context, as they required companies to have a clear organizational structure and definite informative infrastructure. Moreover, they do not assist in identifying and defining actions to reach the highest level. This paper proposes a model for assessing and improving maintenance management information practices. It allows a clear measure of the maturity of the maintenance information management practices in industrial contexts and provides improvement actions identifying the information and data needed to enhance maintenance management information practices.
