    Opis:
    In the paper a method is presented of the best variant selection of a manufacturing process of a rotor to open end spinning machine with use of original optimization proceeding based on adopted criteria, taking into consideration their importance. Unit manufacturing cost and five criteria of manufacturing quality were taken as criteria to the assessment. The assessment criteria resulted from calculations and measurements were normalized. Knowledge of experts was used to determine importance of the criteria taken to the assessment. Each from the experts had built his own importance matrix of the assessment criteria, comparable in pairs, using the Saaty’s method. The weights of individual criteria were determined on the basis of cumulative matrix. In the next stage of the proceeding, normalized decisions were created by raising each assessment to a power equal to corresponding weight. In the last stage of the proceeding, a single optimal ordering comprising the smallest s-th components of the individual decisions d1, d2, …, dm was created. A variant which corresponds to the largest component of the optimal ordering is assumed as the best variant.

    Opis:
    The category of the manufacturing cost of a product is one of the most important ones from the point of view of proper valuation of the assets of a production unit, costs of its operations as well as pricing decisions. This article presents the problem of determining the manufacturing cost of a product in terms of balance sheet law. It has been shown that in order to determine this value various methods and options are allowed by this law, by means of which different values of manufacturing cost of a product are obtained. The importance of a proper selection of an allocation key in settlement of indirect production costs has been highlighted as well as the results of using, in certain cases, approved simplifications in the balance sheet law when determining the manufacturing cost of products have been demonstrated. The problem presented in this article is crucial from the point of view of an organization and management of production as well as managerial decision‐making in a company in the area of design of products and processes.
    Kategoria kosztu wytworzenia produktu jest jedną z najważniejszych z punktu widzenia prawidłowej wyceny majątku jednostki produkcyjnej, kosztów jej działalności oraz decyzji cenowych. W artykule przedstawiono problematykę ustalania kosztu wytworzenia produktu w ujęciu prawa bilansowego. Wykazano, że prawo to dopuszcza różne metody i warianty ustalania tej wielkości, przy których uzyskiwane są różne wartości kosztu wytworzenia produktu. Podkreślono znaczenie prawidłowego doboru kluczy rozliczeniowych w rozliczaniu kosztów pośrednich produkcyjnych oraz wykazano skutki stosowania dopuszczonych, w określonych przypadkach, w prawie bilansowym uproszczeń w ustalaniu kosztu wytworzenia produktów. Problematyka zaprezentowana w artykule jest istotna z punktu widzenia organizacji i zarządzania produkcją oraz podejmowania decyzji menedżerskich w przedsiębiorstwie w obszarze projektowania wyrobów i procesów.

    Opis:
    The use of 3D printing technology allows to make simple machine parts including agricultural machinery in home conditions using FDM printers. Printing technology can be used to produce machine components that are subject to accelerated wear or variable strains that damage them. It is an alternative to parts made of plastics whose cost is significant and the availability is limited. The article presents an analysis of the quality of printed elements and the cost of their production from one of the most commonly used printing material which is ABS. The FENDT 412 Vario tractor engine cover latch assembly was analyzed. The results of the research indicate the possibility of using 3D printers for the production of agricultural machine parts in the home conditions. Elements with the required shape and strength were obtained at much lower production costs.
    Zastosowanie technologii druku 3D pozwala na wykonywanie prostych elementów maszyn, w tym również maszyn rolniczych w domowych warunkach, z wykorzystaniem drukarek FDM. Technologia drukowania może zostać wykorzystana do wytwarzania elementów maszyn, które ulegają przyspieszonemu zużyciu lub są narażone na zmienne naprężenia, powodujące ich uszkodzenie. Jest to alternatywa dla części wykonanych z tworzyw sztucznych, których koszt zakupu jest znaczny, a dostępność ograniczona. W artykule poddano analizie jakość wydrukowanych elementów oraz koszt ich wytworzenia z jednego z najczęściej wykorzystywanych podczas drukowania tworzyw, jakim jest ABS. Analizie poddano zespół zatrzasku pokrywy silnika ciągnika rolniczego FENDT 412 Vario. Wyniki badań wskazują na możliwość wykorzystania drukarek 3D do produkcji elementów maszyn rolniczych w warunkach gospodarstwa domowego. Uzyskano elementy o wymaganych kształtach i wytrzymałości, przy znacznie mniejszych kosztach produkcji.

    Opis:
    World Class Manufacturing system consists of ten technical and ten managerial pillars. These, impacting directly and indirectly on each other, generate the flow of internal processes. Two of the mentioned pillars, Early Product Management (EPM) and Cost Deployment (CD) play a special role in the system, because they create a future strategic management of a company influencing design engineering, manufacturing and economy [1, 2]. Referring to the author’s previous publications on Early Product Management methodology [3, 4], the role of Cost Deployment pillar in the new product launch remains an important issue. Additionally, there is a noticeable lack of publications in this specific field of the WCM system. Therefore, a proper understanding of the relationship between these two technical pillars is the basis for effective project management for the implementation of new products. In this article, the correlation between EPM and CD will be highlighted whereas some critical remarks will be indicated. The main part of the article will describe: the current approach to project management according to the standards set by the WCM system and recommended improvements originated from EPM and CD pillars. The quality scientific methods used in this article are based on a case study of internal processes in an international plant specializing in agriculture machinery production and include elements of direct observation and theoretical analysis and synthesis. This paper refers to the presented issues in practical terms on the example of the methodology of managing of new launch product projects in terms of cost management. The purpose of this paper is to draw attention to the problem of the cost factor generated during the design phase and early implementation of the new product into production, which will enable effective cost management of new implementation projects.

    Opis:
    The problem of sequencing jobs on a single machine to minimize total cost (earliness and tardiness) is nowadays not just important due to traditional concerns but also due to its importance in the context of Collaborative Networked Organizations and Virtual Enterprises, where precision about promptly responses to customers’ requests, along with other important requirements, assume a crucial role. In order to provide a contribution in this direction, in this paper the authors contribute with an applied constructive heuristics that tries to find appropriate solutions for single machine scheduling problems under different processing times and due dates, and without preemption allowed. In this paper, two different approaches for single-machine scheduling problems, based on external and internal performance measures are applied to the problem and a comparative analysis is performed. Computational results are presented for the problem under Just-in-Time and agile conditions on which each job has a due date, and the objective is to minimize the sum of holding costs for jobs completed before their due date and tardiness costs for jobs completed after their due date. Additional computational tests were developed based on different customer and enterprise oriented performance criteria, although preference is given to customer-oriented measures, namely the total number of tardy jobs and the maximum tardiness.

    The objective of this research is to propose an indicator to assess and rank environmental problems caused by production within the food manufacturing sector of Thailand. The factors used to calculate the real benefit included the costs of natural resources, energy and transportation, fertilizer and pesticides, and sanitary and similar service. The highest environmental cost in terms of both natural resources materials and energy and transportation was ice, while the highest environmental cost for fertilizer and pesticides was coconut and palm oil. Confectionery had the highest environmental cost for sanitary and similar services. Overall, real estate gained the highest real benefit, while repair not classified elsewhere had the lowest real benefit for the company. If Thailand uses an indicator of environmental harm, especially within the food manufacturing sector, it could help to formulate efficient policies and strategies for the country in three areas of development, which are social, economic, and environmental development.

    Opis:
    This paper is a  literature review to compare selected dimensions of manufacturing, services and R&D sectors supply chains. Each supply chain is seen as a  system which proper input should be proceed to gain appropriate output. Therefore, to study the supply chains, inputs, outputs and the processors specifications should be considered and the most common characteristics of each sectors’ input and output are investigated; additionally, due to wide range of supply chain specifications the factors are brought from the literature to the model to have a  unique structure of comparison: quality, cost, flexibility, competitiveness, resource utilization and innovation. The final result is a  comparison of the factors in manufacturing, service and R&D sourcing.Purpose – This paper is a  literature review. Due to novelty of R&D sourcing in compare with tangible manufacturing sourcing and intangible service sourcing, and lots of models and procedures from manufacturing sourcing were modified in services sourcing, we tried to compare manufacturing and services sourcing bold aspects with R&D souring to find out the possibilities of such modifications. Additionally, exploring on the similarities and differences could lighten up sourcing strategy selection processes.Design/methodology/approach – Supply chain management is initiated in manufacturing companies, and then various methods, procedures and strategies are modified, developed, and applied at service sector organizations. Therefore, R&D supply chains can be understood by comparing various factors of manufacturing (tangible) and service (intangible) supply chains to find opportunities for modification or innovation in R&D supply chains. The supply chain is a  system in which the input should pass out the processor to be converted into the appropriate output. Thus, in this study, inputs, outputs, and processors of supply chains are studied. Using the variation and range of supply chains factors as processor criteria, the most important characteristics of supply chains are studied: quality, cost, flexibility, competitiveness, resource utilization, and innovation.Findings – The result of the study is a  general comparison of R&D, manufacturing, and service supply chains in terms of these criteria: quality, cost, flexibility, competitiveness, resource utilization, and innovation that gives a  synergetic view pointsOriginality/Value – Modifying and developing sourcing strategies and procedures in manufacturing and service sourcing are possible approaches. The possibilities and opportunities in R&D sourcing were evaluated. Subsequently, there are not any other researches which compare R&D sourcing with manufacturing and services.

    Opis:
    The first-priority directions for modern engineering, especially for multiproduct manufacturing, include the intensification of manufacturing processes, increasing the efficiency of technological equipment, and reducing the time required to implement technological solutions. Fixture design is a complicated and time-consuming process that requires considering many parameters of the closed-loop technological system “machine tool — fixture — cutting tool — workpiece”. One machined part can have several fixture layouts corresponding to all specified parameters; however, their effectiveness differs depending on production conditions. Search for an optimal fixture for specified production conditions is an essential stage of production planning. It has been proved that the efficiency of a manufacturing process should be assessed using single economic indicator — the cost of machining, which considers the costs of time, the total costs for process realisation, and a batch of parts. The paper aims to substantiate the efficiency of manufacturing processes in machining complex parts using flexible fixtures by developing a mathematical model that considers the cost of time, the cost of implementing the manufacturing process, and the batch value of parts production. This approach estimates the efficiency of manufacturing processes for machining complex parts and choosing the flexible fixture layout that corresponds to specific production conditions. It was proved that flexible fixtures could be effectively used for machining small batches of parts with frequent readjustments to new workpieces and short-term machining. A tendency has been established that the higher number of nomenclature of parts contributes to expanding the scope of the effective use of flexible fixtures.

    Opis:
    The aim of the article is to present a proposal and discuss the production cost calculation procedures based on data collected during manufacturing process, according to standard SPC control chart evaluation. It is applied as a tool to support the process of continuous improvement of the manufacturing process and improve profitability by reducing the cost of production. Research methodology - the study uses the results of a literature review on the issue of cost analysis and their modeling. Key elements are the main cost components, but also those that are considered less important and may be overall decisive. Application of Statistical Process Control - as a method of data collection for cost modeling to improve overall cost structure is proposed. Originality/value - the considerations presented in the study may be the basis for determining the key components of the cost of production. The proposed simulation model allows for the determination of the main quality cost factors. This, in turn, should allow to define the main directions of searching for the optimization of the product cost in order to achieve the expected level of cost and quality.

    Opis:
    Opracowano nową metodę określania złożoności części stosowaną do ich kwalifikacji do obróbki w elastycznym systemie obróbkowych (ESP) bez konieczności opracowywania procesów technologicznych. Na podstawie złożoności części i złożoności granicznej systemu można określić w jakim systemie elastycznym czy konwencjonalnym części powinny być wytwarzane. Opracowaną metodę zweryfikowano na przykładzie kół zębatych wytwarzanych w Kombinacie Przmysłowym Huta Stalowa Wola.
    The new method for defining the complexity of machine parts which can be applied for their qualification for machining in Reconfigurable Manufacturing System (RMS) without necessity of designing the technological processes. Basing on the complexity of part and boundary complexity of the manufacturing system it can help defining which system (reconfigurable or conventional) should be used for manufacturing. The developed method was verified using toothed wheels manufacturing in "Huta Stalowa Wola" Steel Mill.
