Currently, companies must change and evolve to keep pace with the changing environment, customers’ requirements and to be better than their competitors. The changes result from the need to adapt the products to new customers’ requirements as well as to maintain competitive prices of their products. Therefore, companies should be flexible to guarantee short lead time and minimalize their costs to offer a good price for the customers. At the same time, companies should create good work environment for their employees in order to get them involved in improvement processes. In order to survive and develop companies should motivate and involve their employees into a continuous improvement process in different areas of the company. Unfortunately, as based on the companies’ practice and previous research, in many cases employees are not willing to engage in the company development. Continuous improvement is the basis of the philosophy of Quality Management and Lean Manufacturing, which come from Toyota Production System (TPS). The TPS eventually spread throughout the world, and it is held up as an example of the proper management of a production system. The assumptions of TPS system were used to build systems in other companies, but not always with the same success as it was in Toyota. For this reason, the authors of this paper seek to answer the question of whether there are differences in engagement in a continuous improvement process between employees in a Japanese company and a Polish company operating in the same industry and realizing the similar manufacturing. In order to verify this, the research was conducted in two manufacturing companies which operate in the automotive industry. The results of the study and their analysis are presented in the work.

EN
The purpose of this paper is to propose the methodology for the setup analysis, which can be implemented mainly in small and medium enterprises which are not convinced to implement the setups development. The methodology was developed after the research which determined the problem. Companies still have difficulties with a long setup time. Many of them do nothing to decrease this time. A long setup is not a sufficient reason for companies to undertake any actions towards the setup time reduction. To encourage companies to implement SMED it is essential to make some analyses of changeovers in order to discover problems. The methodology proposed can really encourage the management to take a decision about the SMED implementation, and that was verified in a production company. The setup analysis methodology is made up of seven steps. Four of them concern a setups analysis in a chosen area of a company, such as a work stand which is a bottleneck with many setups. The goal is to convince the management to begin actions concerning the setups improvement. The last three steps are related to a certain setup and, there, the goal is to reduce a setup time and the risk of problems which can appear during the setup. In this paper, the tools such as SMED, Pareto analysis, statistical analysis, FMEA and other were used. Implementing the proposed methodology can change the attitude of the management. The risk analysis helps to prevent problems with a setup. This methodology can be used in production companies which make changeovers, particularly, in the companies where SMED hasn’t been introduced yet.

Działania realizowane w zakresie nadzoru nad infrastrukturą techniczną są szczególnie istotne dla dużych przedsiębiorstw. Powszechnie panuje przekonanie, że w dużych przedsiębiorstwach istnieje duży zakres zadań realizowanych w ramach nadzoru nad infrastrukturą techniczną. Dotychczas przeprowadzone badania wskazują jedynie na stosowane w przedsiębiorstwach strategie nadzoru nad maszynami, jednakże nie wskazuje się, jakie działania są konkretnie realizowane. W rzeczywistości mimo zasad przyjętych dla każdej strategii w praktyce nie są one tak do końca stosowane. Celem badań, których wyniki przedstawiono w niniejszej pracy, było zidentyfikowanie rzeczywistych działań, które są prowadzone w przedsiębiorstwach w zakresie nadzoru nad infrastrukturą techniczną w dużych przedsiębiorstwach. Badania dotyczyły przedsiębiorstw produkcyjnych funkcjonujących w różnych branżach przemysłu na określonym obszarze. Wyniki badań opracowano i przedstawiono w postaci graficznej. Wyniki badań wskazują zarówno na te działania, które są powszechnie realizowane, jak i na te, które rzadko występują w tej grupie przedsiębiorstw.

The activities realized within the technical infrastructure supervision are particularly important for large enterprises. It’s commonly believed that in large enterprises there is a wide range of tasks realized within the technical infrastructure supervision. The studies done so far indicate only the machine supervision strategies used in enterprises, yet it doesn’t indicate what activities are specifically realized. In fact, in spite of the rules adopted for each strategy, they are not used entirely in practice. The aim of the survey, of which the results are presented in this paper, was to identify the real activities conducted in enterprises within the technical infrastructure supervision in large enterprises. The survey concerned production enterprises functioning in different industries on a specified area. The results were drawn up and presented graphically. The results indicate both the activities which are commonly realized and those which are rare in this group of enterprises.

The article focuses on the problems concerning production line capacity. The example of a certain problem concerning a line, on which the axles for grass mower are producing, is analyzed in the paper. To solve the problem authors used lean tools such as value stream mapping and ProModel program for simulation of the production line working. After gathering information about production line and processes realizing on the line, the current state of the value stream map was drawn. On the base of the map analysis and talks with employees and management the improvements, which could improve production line working and its capacity, were proposed. Improvements were discussed and chosen of them were indicated to check in simulations. Then a first version of future state of value stream map with the indicated improvements was prepared. To do simulations a plan was developed. As variables are taken: frequency of delivery, effective working time, number of simultaneously assembled products, number of lathes in the line and number of products in batch. Next a model of the production line in ProModel program was build. With the use of the model, in the range of the analysis, 144 simulations were done. Obtained data are analyzed and proposals for line developing are presented. To increase production line capacity an additional lathe has to be introduced into the line. Authors also indicate that morning break should be cut down to 5 min. Another solution, which has to be introduced, is changing a frequency of delivery. The frequency should equal 8 hours and it is enough. More often deliveries are not cost effective, although they could give even better capacity. It was impossible to double capacity by introducing only other improvements avoiding costs concerning with necessity of buying a new lathe. The proposals are shown in the second version of future state of value stream map. Authors also indicate the further possible development and analysis.

Implementation of the quality costs account is a difficult process. Companies realize that quality costs are important element of costs in general. But most of firms register only chosen quality costs. The main goal of costs accounting is finding which processes, activities and cells generate maximum costs to know where developing should be introduce. In the work the chosen models of quality costs are presented. Next, the authors presents a model of quality costs account, which one of the company has chosen to introduce. In the model four groups of cost are distinguished. These are costs of preventing actions, costs of inspections and quality assessment, costs of internal nonconformities and costs of external nonconformities. In the article elements of each group are presented. The authors also presents a schedule of quality costs account implementation. The phases of implementation process are described. The article specifies costs, which were registered earlier in the company and these are costs of nonconformities, especially costs of defective products, costs of repairs and costs of corrections. Causes of nonconformities identified in the company are enumerated in the article. The procedure for quality costs account leading are presented and connections with SAP R/ 3 system are indicated. Finally methods of costs counting are presented. The work also indicates advantages and difficulties concerning full quality costs account leading.

One of the quality management rule requires from organizations keeping good relations and cooperation with suppliers. To have a possibility to do that, first we should choose these suppliers who are able to meet company's requirements. Next we can assess a risk concerning cooperation with a certain supplier and evaluate an influence, which bad cooperation can have on our organization. In the paper authors present requirements and guidelines concerning purchasing process and cooperation with suppliers of quality standards such as ISO 9001, EN 9100 and ISO 9004. The authors also describes methods for suppliers evaluation and examples of indicators, which can be used to assess suppliers. Suppliers are usually assessed in respect of quality and price of products, and supplies punctuality. Next, authors propose a method for a risk assessment of cooperation with suppliers. The method gives consideration to probability of appearing negative results in future and influence on organization's functioning. The information specified in the article are taken into consideration to assess a risk. The method was worked out for a big company and tested in this company. Using the method 41 company's actual suppliers were evaluated to find out what is the risk concerning cooperation with these suppliers. The method is flexible and can be easy adapted to different organizations. To facilitate using the method we can use a spreadsheet program, like in this case.

In the work the chosen methods for evaluation of a significance of controllable parameters in technological process results are compared. The task was realized on the basis of roller burnishing process of turned shaft made of 1.503 steel. The methods, which are compared are: a 23 full factorial design and a Shainin method. Considered controllable parameters were: rate of feed, force of roller pressure and spindle rotation speed. Experiments conducted to minimize roughness (Ra parameter) after treatment, in case of the 23 full factorial design, enable to obtain a formula after relatively labor-intensive calculations. In case of the Shainin method it was possible to obtain faster approximate results comparable with these obtained using the 23 full factorial design.
