Opis:
Analysis of the incompatibilities occurring in an organization relies on identifying the problem and then applying the appropriate corrective and improvement actions. It is possible by using appropriate instruments of quality management and, basically, their sequence, which is a modern way of solving the problem, and it enables the improvement of functioning of an enterprise. Therefore, it is advisable to select an appropriate group of quality management instruments and use them in the appropriate sequence, because then they are complete and lead to full analysis and conclusions adequate to the problem. The aim of the article is to analyze the correlation and influence of the selected factors on the incompatibilities in selected processes, i.e. the production process of furniture fronts and furniture in general. Moreover, the idea is to use the appropriate sequence of instruments of quality management to solve various types of incompatibilities. The analysis was made at a company where a lot of different kinds of incompatibilities in processes were identified within 9 months. It was important to solve the problem for this enterprise because it was generating relatively large financial losses, and the lack of identified causes of the problem precluded taking preventive actions and developing the enterprise. After the initial analysis of the processes and problems, it was decided to use the correlation analysis, the Pareto-Lorenz diagram, the 5W2H method, the Ishikawa diagram and the 5Why method. The methodology and conclusions drawn from the analysis may be useful in solving complex problems at other production and service enterprises.

Opis:
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.

Opis:
The analysis of the problem of the mechanical damage was made for a company manufacturing furniture and furniture fronts. From January to September the company identified 285 pieces of mechanically damaged products. The management of the company wanted to identify the source of the incompatibility; therefore, it was purposeful to analyse the problem of the mechanical damage using the sequence of the selected instruments of the quality management that enable this. Additionally, until now the company has not used the instruments of the quality managements to analyse the problems involving nonconformity, so it was important to show the company their practical use. The aim was to analyse the problem of the occurrence of the mechanical damage in fronts and furniture and to identify the root cause of the problem. Also to show the effective use of the sequence of the quality management instruments (i.e. 52WH method, Pareto-Lorenz diagram, Ishikawa diagram, 5Why method) to solve the problem of incompatibility. It was concluded that the root cause of the mechanical damage of fronts and furniture was the lack of management knowledge and awareness of the need to implement visualization principles in the company. The analysis and the proposed improvement actions may be practiced in other companies from both the production and service industries.

Opis:
Purpose: The analysis process of the causes of the problem by often used the Ishikawa diagram is not effective when knowledge is lacking with regard to the particular causes and their validity about the problem. Moreover, its subjectivity is affected by the people undertaking the analysis. The aim of this paper is to reveal ways of improving the analysis process of problem causes by utilising the new method of integrated techniques, i.e.: Ishikawa diagram and FAHP method. Design/methodology/approach: An analysis process of problem causes was made by utilizing the integrated techniques, i.e.: Ishikawa diagram and FAHP method. The problem was identified after the FPI method, and it was a linear indication on the bearing cover from 410 steel. Findings: It was shown that implementing the FAHP method in the Ishikawa diagram allows a numerical analysis of the main causes of the problem. Research limitations/implications: Future analysis should be undertaken by applying the 5Why method, in order to fully identify the root cause of the problem. Practical implications: A new method can be used to precisely and reliably analyse different types of problems. Social implications: This method is an effective tool that supports the process of analysing the causes of the problem, and thus the process of making multi-criteria decisions. Originality/value: The article proposes a new method for integrating analysis techniques, i.e. the Ishikawa diagram and the FAHP method, which can be effective in precisely and reliably assessing the causes of the problem.

Opis:
As part of continuous quality improvement in well-managed enterprises, identifying unconformity should initiate actions to find their causes. Therefore, it was proposed to the enterprise located in Podkarpacie to use in the sequential way the Ishikawa diagram and 5Why method. The aim was to analyse of unconformity (porosity cluster) on the turbine outlet nozzle and identify the root of its creation. In the enterprise, the quality analysis of the products with a fluorescent method was carried out, but after identifying the unconformity, non-analysis of their reason for their occurrence was not practiced. Therefore, it was intentional to propose the use of sequence i.e. Ishikawa diagram and 5Why method to identify the root of unconformity. The subject of study was the turbine outlet nozzle, on which the fluorescent method the porosity cluster was identified. With the use of the Ishikawa diagram, the main cause of the problem was pointed (unconformity during production), and by the 5Why method the root cause of the problem, i.e. unconformity material from the supplier, was identified. The proposed method sequence is a simple and effective way to make analyses of unconformities and it can be used in different products and service enterprises.

Opis:
Machinery faults are a problem that incorrectly diagnosed may result in the increase of waste. The fault mentioned in the article was identified at an opencast facility located in Podkarpacie. The purpose of the study was to analyse the defect identified on the excavator arm using quality management techniques. These techniques were the Ishikawa diagram and the 5Why method. In the plant, unit faults on various types of machines were detected. The fracture on the excavator arm was identified, however, the cause of the problem was not known. Potential causes of the fault and the main cause of the problem (material fatigue) were detected using the Ishikawa diagram. The root cause of the material fatigue, the long-term and repetitive operation of the excavator during the excavation of the deposit, was identified by the 5Why method. The proposed processes can be used to identify the root causes of various faults both in the mining industry as well as production and service plants.

Opis:
Effective quality management of the product is an element that allows profit within the enterprise. Identifying unconformity and establishing their source enables quality. However, identifying unconformity is sometimes neglected. Such was evident in the analysis of the service-manufacturing enterprise located in Podkarpacie. In the enterprise, quality was assessed via non-destructive testing (via fluorescence), but decisions on sources of non-compliance were made without utilizing additional methods that allow source identification. Hence, the way of recognizing unconformity was not precise. Therefore, method sequence (Ishikawa diagram and 5Why method) approaches were proposed to enable this. The aim of this paper is to show the effectiveness of such approaches in identifying sources of unconformity. The subject of study was tubing that is used in aircraft engines. Via the applied analysis, the unconformity in production and the source cause was traced to material supplied from outside. The proposed method sequence approach can be used in other enterprises for quality analyses purposes.

Opis:
Identifying inconsistencies and taking adequate actions to eliminate them is an effective way to improve the quality of products. Casting products are one of the items commonly manufactured in the foundry industry. Determining their quality becomes problematic due to a large number of factors affecting them during production which can generate various types of incompatibilities. The problem with a large number of incompatibilities of castings arose in a company in the southern part of Poland. The aim of the research was to diagnose the state of a batch of castings of industrial robot arm parts and to precisely determine the most important reasons for the occurrence of unworthiness, in relation to which appropriate preventive measures could significantly contribute to the reduction of the number of non-compliant castings and hence, waste. The analysis of incompatibilities occurring in the casting using the Pareto-Lorenz method and the ABC method allowed indication of the most important (in terms of frequency and severity) incompatibility of castings - gas porosity. Continuing the analysis of the problem by means of a brainstorming session and organizing ideas via the Ishikawa diagram made it possible to identify the key cause of the problem, which was the inadequately prepared (wet) core of the casting mold.
