Opis:
The engine is the most important component of a vehicle. It attaches to the main frame via the engine mounting bracket which supports weight and operating loads. The engine mount therefore plays a crucial role in the durability and comfort of the vehicle. This article contributes to the search for the most optimal model from the point of view of resistance, environmental impact, and manufacturing cost. This involves, on the one hand, optimizing the support by reducing its initial mass by 30%, and on the other hand, seeking suitable material and manufacturing process with the least environmental impact. To this end, topology optimization will be combined with an environmental assessment and a manufacturing cost analysis. Four materials will be tested and evaluated. Finally, a cost analysis will present a comparison between a conventional process and 3D printing.

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:
Dla umów o wykonanie robót budowlanych wymagana jest forma pisemna. Jednym z istotnych punktów takiej umowy jest sposób rozliczenia wykonanych prac. Kodeks cywilny definiuje dwa rodzaje rozliczenia: ryczałtowe i kosztorysowe. Każde z nich ma swoje wady i zalety. Różnie też rozłożone jest ryzyko związane z zawarciem umowy o roboty budowlane. W przypadku kontraktu ryczałtowego wyższe ryzyko ponosi wykonawca, niższe – zamawiający. Inwestor może liczyć na to, że niezależnie od ilości niezbędnych do wykonania robót dodatkowych, tj. nie przewidzianych umową, kwota, jaką będzie musiał zapłacić wykonawcy, nie przekroczy planowanej, podanej w umowie. W przypadku rozliczenia kosztorysowego – które nazywane jest także obmiarowym – ryzyko wykonawcy jest dużo mniejsze, niż przy umowie ryczałtowej.
Some contracts, like the one for construction works are legally required to be in written form. One of such important aspects is a detailed settlement of performed works. The Civil Code defines two types of such choice: lump sum remuneration or remuneration by cost estimation. Both options have advantages and disadvantages. In case of a lump sum contract, a higher risk is borne by the contractor and lower by the contractee. The investor can expect that regardless of the amount of additional works, not provided in the contract, the amount that he will have pay to the contractor will not exceed the amount specified in the document. When it comes to remuneration by cost estimation – remeasurement – constructor’s risk is much lower than in case of a lump sum contract.

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 pre-operative preparation of a surgeon is increasingly often extended to individual patient’s anatomical models depicting the affected organ and the existing lesion in relation to the surrounding structures (e.g. blood vessels). Among the models, there are models of the skeletal system, in which the FFF technology is used. The models of parenchymal organs are more difficult to reproduce due to the material limitations in the FFF technology, which is why alternative technologies such as PolyJet and SLA are used. Due to the high price of models, they are employed less frequently, especially in the Polish hospitals. The research presented in the article deals with the modification of the existing methodology of rapid pre-operative models production with the use of various low-budget rapid manufacturing techniques, which use materials of low hardness, similar to the human soft tissues. The aim was to create a methodology and determine the parameters of materials that allow for the cheap production of functional pre-operational aids.

Opis:
In today's business environment enterprises are trying to establish reorganization changes in their work and organization. It is necessary to structure the existing business to understand all enterprise functions, and change them in order to achieve the main enterprise objectives. To stay competitive under new conditions the external and internal factors should be assessed before restructuring of existing practices. The goal of this paper is to show how to put into practice the process of transition from Small-sized enterprise to Medium-sized enterprise category. For this purpose the existing company data that is stored in the ERP system should be transformed into knowledge. In this paper we consider the conditional "Metal Service" enterprise that produces various metal constructions and plans to produce load lifting equipment (jib cranes, overhead cranes, and additional equipment for existing cranes) for manufacturing enterprises that produce heavy products. The manufacturing capacities of enterprise are defined based on IDEF0 functional model created for each type of product. The simulation results received from these models enables to analyse new production processes, to estimate production time and route for all type of unit and yearly product release. In addition, after the Systematic Layout Planning (SLP) methodology and Relationship Matrix (RM) was applied to simulation results it became possible to calculate new manufacturing area, facilities layout and to assess the new production capacities.

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.

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.

Assembly lines are special flow-lines production systems which are typical in the industrial production of high quantity standardized commodities. Assembly line balancing is based on evenly distribution of operations between workstations so that each idle time of the machines was minimal. It is assumed that operation times on the machines and the precedence relationship existing between the operations which results from the technology of the production line and the cycle time or the number of machines are known. In the paper short description about general assembly line problem and cost-oriented is described. Next the author presents description of used algorithms. A numerical example is calculated and the results are discussed. Presented paper shows that cost oriented assembly line balancing problem differs from time oriented problem and the differences are underlined.

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.

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 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:
Inventory management’s fundamental problem starts with maintaining equilibrium among the operating efficiency, cost of investment, and other allied costs with extensive inventories to keep the actual conflicts at the minimum while optimizing the inventory holding levels. But, inventory management practices have not been well exploited in various manufacturing industries yet. In this study, inventory management tools, i.e., ABC and VED analysis, have been applied in the manufacturing industry, considering 146 items as raw material for an assembly. A total of 15 items under ‘AV’ class have been identified that consume 82.05 % of the total cost, and these items need strict control and frequent ordering. Sigma level of suppliers is also calculated, which comes out to be 2.36, and it must be improved to reduce the overall inventory cost.

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:
Modern manufacturing entities often operate in capital groups, and their role is sometimes limited to the function of cost centers. From the legal point of view, however, they are separate entities obliged to apply transfer pricing regulations. Meeting the requirements of the arm's length principle can be very difficult at this time, given the relationships and conflicts of interest in the capital group. Complexity increases in capital groups operating in different countries, due to differences in tax regulations. The main purpose of the paper is to demonstrate that the need to valuate the sale of finished goods to a manufacturing entity, which is a subject to a different tax jurisdiction, may lead to a problem of compliance with the arm's length principle. In addition, the paper proposes a methodology for comparability analysis that may be used by manufacturing entities to defend conditions of setting transfer pricing. The paper presents the different functional profiles of manufacturing entities and points out the difficulties that they may encounter when preparing the comparability analysis. It has also been noted that there are differences in transfer pricing regulations in different countries, for example by analyzing Polish and Czech regulations. The lack of uniform benchmarking legislation can cause inconsistencies in the selection of comparable data, resulting in differences in transfer pricing. The paper uses the method of legal regulation review and analysis of results of published studies concerning the scope of transfer pricing and comparability analysis. The paper also adopts a case study analysis.

Opis:
Titanium alloys are mainly used in the automotive, aviation, shipbuilding and military industries. Their main advantages are low specific gravity, resistance to cracking and corrosion, high strength as well as fatigue strength. The most important disadvantages of titanium alloys include low thermal conductivity, difficulties in their machining and high cost of manufacturing. For the latter reason, titanium alloys are primarily used for the manufacturing of highly responsible components, such as implants and aviation structures, while the remaining products are produced in limited series. In the appropriate conditions, many titanium alloys can be formed in hot working processes. At present, in the processes of manufacturing structural elements of titanium alloys, a semi-finished products obtained by the casting method are commonly used. However, more and more research is being carried out on the use of powder metallurgy based material in this field. This approach opens up the possibility of decreasing production costs. As initial material, the alloy powders or mixtures of elemental powders can be used. The properties of alloy powder products are usually high and stable, however, the cost of powder production is high. Obtaining product from titanium alloys based on a powders mixture is relatively simple and significantly cheaper. The disproportion of prices causes, that a great number of research projects realized in recent years in the field of implementation of powder metallurgy for manufacturing titanium-based products is directed towards the use of powder mixtures since this approach gives real chances for the successful implementation of cost effective titanium alloys processing technology.
Stopy tytanu są stosowane głównie w przemyśle motoryzacyjnym, lotniczym, stoczniowym i wojskowym. Ich głównymi zaletami są niski ciężar właściwy, odporność na pękanie i korozję, wysoka wytrzymałość oraz wytrzymałość zmęczeniowa. Do wad stopów tytanu można zaliczyć niską przewodność cieplną, skomplikowaną obróbkę mechaniczną i wysokie koszty produkcji. Z tego ostatniego powodu stopy tytanu są stosowane przede wszystkim do produkcji wysoce odpowiedzialnych elementów konstrukcyjnych, takich jak implanty i struktury lotnicze, podczas gdy pozostałe produkty są wytwarzane w ograniczonym stopniu. Stosując odpowiednie parametry termomechaniczne, stopy tytanu mogą być z powodzeniem kształtowane na drodze przeróbki plastycznej na gorąco. Obecnie w procesach wytwarzania elementów konstrukcyjnych stopów tytanu powszechnie stosuje się półprodukty uzyskane metodą odlewania. Jednak w tej dziedzinie prowadzone są coraz więcej badań nad wykorzystaniem materiałów opartych na metalurgii proszków. Takie podejście otwiera możliwość obniżenia kosztów produkcji. Jako materiał wyjściowy można zastosować proszki stopowe lub mieszaniny proszków elementarnych. Wykorzystanie proszków stopowych zwykle zapewnia wysokie i stabilne własności, jednak koszt produkcji takiego proszku jest wysoki. Otrzymywanie produktów ze stopów tytanu na bazie mieszaniny proszków elementarnych jest stosunkowo proste i znacznie tańsze. Dysproporcja cen powoduje, że ogromna liczba projektów badawczych zrealizowanych w ostatnich latach w zakresie wdrażania metalurgii proszków do wytwarzania produktów na bazie tytanu jest ukierunkowana na stosowanie mieszaniny proszków elementarnych, ponieważ takie podejście daje realne szanse na pomyślne wdrożenie opisanej technologii przetwarzania stopów tytanu.
