Designing and proper implementation of effective processes and providing the customer with high quality products undoubtedly determines the stable position on the market. The aim of the study was to analyse the cost and value of the technological process of doors in the context of creating added value and to identify unnecessary processes (not creating added value) in relation to which appropriate corrective actions could contribute to their elimination. Thanks to the application of remedial measures, consistent with the lean manufacturing concept, the study eliminated, among other things, operations related to unnecessary transport and storage of products, which resulted in both the reduction of time and costs of process implementation.
Making a complex analysis of the problem in order to identify the root of its occurrence, is the process burdened with the risk of uncertainty. This risk is in case of the quality analysis, in which the choice and making a decision is not confirmed by reliable information (number). This risk is in case of the quality analysis, in which the choice and making a decision is not confirmed by reliable information (number). But these techniques do not include the risk of uncertainty, so their sequence should be expanded about the appropriate method, to take this into account. It was considered beneficial to demonstrate that this method is the Fuzzy Analytic Hierarchy Process method (FAHP). The aim of the study to implement the FAHP method in the sequence of traditional quality management techniques (Ishikawa diagram and 5Why method) and proposition new, not practiced yet the method to complex analysis of the problem and identify the root of its root cause. The subject of the study was the furniture front, on which the incompatibility was identified (shortened foil). From the categories to which the potential causes of the inadequate foil were assigned, by using the Ishikawa diagram and the FAHP method in an integrated manner, were defined the most important categories (method and machine) in a precise (numerical) way. Next, using the same tools, the relationship between the potential causes was analysed and selected the main causes of the problem. Then, by using the 5Why method the root of the problem was defined (lack of the new machine and failure to comply with labor standards). The obtained results could differ depending on the subjectivity, however, the method itself proved to be effective and can be used to solve other types of the problem.
The use of cast aluminium has still increased, so have the mechanical property requirements. By casting and also in other metallurgical processes, the inclusions enter to the molten aluminium alloy and it exhibits poor ductility or toughness. It can cause a variety of problems in the manufacture of aluminium alloy castings. Therefore, the purification of the molten aluminium alloy is one of the most important processes for improving the quality of Al-products. Filters have been used for many years in order to improve the quality of castings. The inclusions in molten secondary AlSi7Mg0.3 cast were removed using depth filtration by ceramic foam filters of 20 ppi porosity. Were used 4 types of ceramic filters in 2 thicknesses (15 and 22 mm); Brinell hardness and porosity were measured. Quality of microstructure (occurrence of oxidic particles and larger non-metallic inclusions) was observed. Experimental results show that the insertion of ceramic filters into the inlet system has contributed primarily to a decrease in porosity. On the microstructure, the inclusion of filters was not significantly reflected.
Presented paper concentrate on problems connected with the function of operation management within the company. Operation function is responsible for producing products and delivering services. But it needs support and input from others areas of the organization. The aim of the paper it to analyze on the basis on inter-national the main functions of operation management. We can distinguish seven main functions of operation management in the industrial enterprise: planning, scheduling, purchasing, controlling, quality control and inventory control. In each of those fields operations managers should conduct many decision affecting of-organization effectiveness.
The developing countries of Asia, are faced with rapid changes as far as the economic, political, socio-cultural factors are concerned. These changes require greater investment in basic and higher education, as well as development of skills, in order to support the transition to a high-tech, service-oriented economy. Today, most Asian countries are trying to solve these problems by restructuring or reforming their education systems. The following article discusses the state of educational processes in the technical fields of higher educational institutions of the countries of the Commonwealth of Independent States. The results of the study show a high level of development of government strategies to maintain technological modernization of the country.
One of the factors allowing to shape safety and quality of a postal service is an opinion of its customer. In the following paper, the analysis of the impact of a customer’s perception of safety on the service quality assessment has been presented. Research results presented in the paper refer to opinions of traditional and digital customers of postal services. The presented analysis is enriched by a theoretical framework of service quality, the explanation of the concept of safety, and a complementary characteristics of traditional and digital postal services. Afterwards, safety attributes of the postal services have been proposed, explained and highlighted. Subsequently, the results presented in the paper refer to the validity of particular chosen safety attributes of postal services.
Handicraft production is usually chaotic and difficult to monitor, since its products and manufacturing processes are complex. As all the manufacturing steps rely on varied skill levels of the workers, the situation is even more stochastic. There are several common problems, such as inappropriate production method, line unbalance, excessive stock, lack of production planning and control phases, etc. They stem from the lack of suitable operation model, redundant workforce usage, and insufficient internal training activities, which lead to the waste of human resources. In this paper, a roadmap to improve the operational efficiency of handicraft manufacturing is suggested, using Lean-Six Sigma methodology and tools. A case study is conducted in a Vietnamese firm to show the validity of the approach.
Common Agricultural Policy represents the main instrument of the European Union for the development of agriculture and rural areas. European funds are vital for the productivity and competitiveness of agricultural holdings, as well as for the transfer of agricultural knowledge and innovation. Supporting small and young farms is essential for the vitality of rural areas and for the renewal of generations of farmers. The aim of this work is to transfer agricultural knowledge in order to improve the productivity of agricultural holdings, especially among young farmers and small farms. We implemented training program through European funds related to Measure 1. “Actions for knowledge transfer and information actions” from Rural Development Programme of Romania. The characteristic of 100 participants and their responses were analyzed. Most of the participants were young people up to 40 years old (59%). The vast majority of the participants were from the rural area and only 17% were from the urban area. 53% from participants were strongly agree with the fact that level of knowlegde influence farm productivity. Actions for knowledge transfer improve the adaptation of farmers to the new challenges of agriculture, as well as productivity.
All castings can have defects caused by, for example, deviations in material characteristics, structure or properties, but the skillful use of available technologies and quality management tools allows for the detection and elimination of casting incompatibilities as well as the prevention of their recurrence in the future. The aim of the article was to analyse the types of defects in castings, locate the areas with the most frequent occurrence of defects and identify the reasons for the presence of defects in castings of the control panel and its cover. The paper presents the usefulness of a combination of quality management instruments for diagnosing material discontinuities in the analyzed castings.
A constant increase in the production of plastic products is a major cause of general environmental pollution. The past decade recognized how significant recycling plastic waste and the development of biodegradable materials is. This paper takes a new look at reducing the amount of plastic waste in the environment. Plastic bottles are “dressed” in a special PE (polyethylene) foil before filling. After the content is consumed, the foil is removed of the bottle. Such foil can be used for transporting other products more than once. The work focuses on the investigation of the changes in properties of the light density polyethylene (LDPE) foils caused by forming during their application to the bottle. It was decided that the optimal method for this investigation was to compare the mechanical and rheological properties PE foils before and after their application to the bottle.
