Opis:
The maintenance planning corresponds to an approach that seeks to maximize the availability of equipment and, consequently, increase the levels of competitiveness of companies by increasing production times. This paper presents a maintenance planning based on operating variables (number of hours worked, duty cycles, number of revolutions) to maximizing the availability of operation of electrical motors. The reading of the operating variables and its sampling is done based on predetermined sampling cycles and subsequently is made the data analysis through time series algorithms aiming to launch work orders before reaching the variables limit values. This approach is supported by tools and technologies such as logical applications that enable a graphical user interface for access to relevant information about their Physical Asset HMI (Human Machine Interface), including the control and supervision by acquisition through SCADA (Supervisory Control And data acquisition) data, also including the communication protocols among different logical applications.
Planowanie utrzymania ruchu odpowiada podejściu, które ma na celu maksymalizację dostępności wyposażenia, a w konsekwencji zwiększenie poziomu konkurencyjności przedsiębiorstw przez zwiększenie czasów produkcji. W artykule przedstawiono planowanie utrzymania ruchu w oparciu o zmienne operacyjne (liczba przepracowanych godzin, cykle robocze, liczba obrotów) w celu maksymalizacji dostępności pracy silników elektrycznych. Odczytywanie zmiennych operacyjnych i pobieranie próbek odbywa się na podstawie ustalonych z góry cykli próbkowania, następnie dokonuje się analizy danych za pomocą algorytmów szeregowania czasowego mających na celu uruchomienie zleceń roboczych przed osiągnięciem zmiennych wartości dopuszczalnych. Podejście to jest wspierane przez narzędzia i technologie, takie jak aplikacje logiczne, które umożliwiają wykorzystanie graficznego interfejsu użytkownika w celu uzyskania dostępu do istotnych informacji o ich zasobach fizycznych HMI (Human Machine Interface), w tym kontroli i nadzoru przez pozyskanie z wykorzystaniem SCADA (Supervisory Control And Data Acquisition) danych, w tym również protokołów komunikacyjnych pomiędzy różnymi aplikacjami logicznymi.

Lean Manufacturing
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:
In the era of digitization and general access to Internet resources, it seems natural to expect fast, direct, and tailored access to the knowledge of interest. The research shows that the use of modern technologies is not reserved only for industrial solutions, but can be applied in common use. Solutions based on artificial intelligence can provide solutions to many problems of the modern world. This is particularly visible in the era of challenges related to ecology (e.g. minimization of paper consumption) and expectations of fast access to information regardless of place and time. Treating chatbots as a tool supporting the customer in current activities, quick problem-solving shows the potential and care for the image of the producers. Developing the functionality of virtual assistants used for marketing activities with the functionality of technical support can bring tangible benefits both in the economic and social spheres. It should be noted that electronic versions of documents, knowledge transferred in an interactive form can be easily updated and presented in different forms. This increases the attractiveness of transmitted knowledge, users can choose the appropriate form, and access to these resources becomes easier. Artificial intelligence-based tools in the form of chatbots (also called virtual assistants) seem to be a solution worthy of interest. This paper presents the process of developing a virtual assistant to support the maintenance and repair activities of small household appliances. A chatbot aims at gathering in one place and then providing dedicated knowledge resources to an individual user on a just-in-time basis.

Computer systems supporting the management of machines operation and maintenance in companies have been successfully applied in many branches of industry. Over the last few years these systems have been considerably transformed. It also seems that using them for operating mining machines in hard coal mines is inevitable, as maintenance generates high production costs. If implemented, the systems will allow for optimization of stocks, spare parts and materials, supplies, outsourced services as well as maintenance-repair works. Application of a system supporting the management of mining machines/equipment will also enable a better, more effective use of employees. As a result of these actions, the time needed for preparations and repair will be shortened, which will translate directly into the economic effects of mines.

Opis:
The aim of the article is to present the perspective of maintenance development in the context of the 4.0 industry concept. One of the factors that determine the safe and effective use of machines and devices is the properly maintained maintenance process. Correct performance of activities as part of this process requires the use of appropriate knowledge and experience from people implementing this process. Very important in this process is, above all, good organization of work and technical knowledge. The very rapid development of technology causes that teams dealing with the maintenance of traffic in enterprises must systematically acquire knowledge and optimize their activities. Effective exploitation of all types of devices is a set of rules, rules, procedures and actions, the main aspect of which is a human being. Knowledge resources should have appropriate substantive content adapted to the recipient. The article presents a modern solution supporting the maintenance process, taking into account the tools supporting the activities of human teams. The basic principles of maintenance in the enterprise covering machine monitoring systems, production management and management of information on the state of the machine park are discussed. There are also examples of the use of selected tools in the mining industry. Reference was also made to the prospects and directions of the development of maintenance in relation to the fourth industrial revolution.

Opis:
In the article, the authors describe, using the example of a selected class of technical means, their concept of replacing the “classical” linear management (exploitation) model with a circular economy (CE) model. An example of an object for which the authors plan to test the feasibility of the concept presented above is a household washing machine driven by a DC motor. The description of this object included in the article considers its complexity and multiplicity of assemblies, sub-assemblies, and elements. The DC electric motor driving the washing machine was considered the most important from the point of view of the created model, especially in terms of the possibility of maintenance and repair. For such an engine, the article presents the maintenance and disposal model as elements of the concept of building a ‘circular’ business model. The authors assumed that the formal basis for such a model would be the so-called circular model. The methodology and plan of the research carried out at Super Asia washing machine company in Pakistan were introduced, and the research results were shown. With the use of these results, an attempt was made to assess the requirements that the application of the CE business model places on manufacturers of a selected class of devices, both in their manufacture, repair, sharing and dematerialization. The concept of further research is described at the end of the article.

Opis:
Condition monitoring and fault diagnosis of engineering systems are critical for the stable and reliable operation in various areas as mobile technology (primarily agricultural, forestry, mining and construction machinery), railways, airlines and large fleets. Thus, to achieve a satisfactory level of reliability for the life of a machine, proactive maintenance strategy is the only key. This means that the application of classical reliability methods suitable for components with sudden failures can be complemented by technical diagnostic methods which have the potential to provide the information about the system condition. In this article we focus on the diagnostic signal related to the used oil – tribodiagnostic measures and is an interesting theoretical item related to the evaluation of the quality of lubricants in the aspect of operation. This is because the oil is in direct contact with single parts of the assessed technical systems. Results tests were reviewed and derived from various parameters of lubricants and their limits that highlight the condition and state of the lubricants under varying categories which include, physiochemical, elemental (wear), contamination and additive analysis.
