Following the events related to the pandemic and the war in Ukraine, increasing air traffic also increases turnaround agents' activity at airports. Turnaround operations are among the critical activities performed at airports, which must be characterized by punctuality and accuracy of the elementary handling operations. Lack of punctuality in ground handling causes delays in air traffic. On the other hand, a lack of accuracy can also cause disruptions that can turn into aviation incidents. Achieving punctuality and accuracy in aircraft handling is possible by minimizing the resulting disruptions during such handling. The safety management system (SMS) assumes activities to reduce the causes of potential incidents. In the turnaround process, the human factor, the technical aspect, and compliance with existing procedures are significant. The authors have extensively analyzed the disruptions arising during ground handling, learning its causes and effects, which will help avoid adverse events. Occurring disruptions can cause delays in the execution of flight operations but can also cause aviation incidents. Therefore, the authors focused on ground-handling disruptions that can cause adverse aviation incidents. The article presents the interference analysis results as an Ishikawa diagram. Using the FRAM method, an analysis of possible disruptions during the baggage handling process was carried out.

The aim of the work was to determine the effectiveness of the use of the Ishikawa diagram and the Pareto-Lorenz diagram in the analysis and assessment of threats that occur in small sports and recreation infrastructure - playgrounds. After analysing the available literature, it can be concluded that there are studies in the field of safety on playgrounds, but there are no publications combining surveys with the use of quality management tools in relation to this topic. Through a direct survey conducted among parents and caregivers, information was obtained about the threats in playgrounds located near housing estates they meet most often. Using the Ishikawa diagram, this information was grouped and a brainstorming session was conducted to isolate the root causes of these threats. After conducting an analysis using the Pareto-Lorenz diagram, the threats that appeared most frequently in the respondents' responses were specified. The result of the work is to propose actions that can reduce or eliminate these threats.

Dynamic development of various technologies replacing existing, difficult or in various ways arduous, is the reason for replacing equipment with modern ones. New equipment may be associated with a different power supply, a different way that the construction materials are processed or the tools used, than the previous one. Then arises a need to re-examine whether the working conditions at a workplace are safe, what onerous and hazardous factors are associated with the work. An example of such a technological change could be a laser processing, when equipment using a concentrated energy stream, properly controlled, produces a specific effect on materials. However, along with the benefits of the new technology, come also many risks, such as the effects of radiation on matter and the human body, electricity, fire hazards, the problem of toxic emissions and others. This paper presents the problem of ensuring work safety at a newly commissioned CO2 laser station. Technique of brainstorming was used to identify and analyze the working conditions and types of hazards. These may be different from what was previously known, partially known, or even unconscious. Ishikawa diagram was developed and shown to be an effective tool for detailing and structuring problems in relation to safety. In the case of a technical problem, a poka-yoke solution to eliminate the hazard was proposed. Problems occurring at the workstation during machining and related to its operation were assigned, using the affinity diagram, to specific departments of the company, according to its work organization, which can significantly facilitate the management of the work and employees of the different departments in the future, in order to ensure safe and hygienic working conditions.

Conducting an analysis of processes in terms of nonconformities enables the enterprise to continuou sly improve. Construction of a tool in the scope of elimination of nonconformities enabling control over the implementation of preventive actions and data acquisition is, therefore, a necessary action. In literature, there is a lack of examples showing pra ctical use of Ishikawa, Pareto-Lorenz, or FMEA methods and tools created on their basis in production plants in order to improve the control process. The aim of the presented considerations is to analyse the process of controlling nonconformities in a studied production plant, to indicate the causes generating the largest number of registered nonconformities, and to design a tool allowing to improve a given process and minimize the occurrence of defects. For this purpose, the possibilities of implementing the Ishikawa, Pareto-Lorenz, and FMEA methods are presented.

This study aims to practice the implementation of the Fishbone Diagram for Cause & Effect Analysis and prove the validity of the technique’s usability in any construction project to increase productivity for both construction managers and engineers. In every sub-branch of the given Fishbone Diagram, possible failures might be expected to occur unless necessary precautions are taken. The failures, emerge as significant problems and range from possible delays to product quality deficiencies which would affect the acceptance of the project from customers. During the creation of the Fishbone Diagram, the obtained results show us that possible delays are co-existing among each of the 5 M's. Fishbone Diagram in the study also points out there are common issues and similarities between Men and Machine since both 2 M’s lead to progress in a construction project and are interdependent. As a result of this study, usage of Fishbone Diagram Technique demonstrated the possible connections between M’s and determination of the Cause & Effect relations in a construction project. Findings of this study proved that usage of Cause & Effect Analysis in construction projects is also practical to determine the key points of a construction and interdependent factors.

The paper presents the definitions of the term quality quoted in the literature on the subject. FMEA (Failure Mode and Effects Analysis) methodology was presented. A reloading ramp was characterized as the subject of the study. A cause-and-effect analysis of non-compliance in the finished product was performed using the Pareto-Lorenz diagram, Ishikawa diagram and brainstorming. The FMEA analysis of the assembly table indicated the elements of the workstation causing the most frequently occurring non-conformities. Based on the obtained results, corrective actions were proposed to reorganize the assembly station. The implemented activities made it possible to reduce the critical RPN coefficients for the elements of the assembly table and to shorten the time necessary to make one piece of the finished product.

Business continuity depends on the quality of management of individual processes. The management team strives to anticipate all possible threats and define protective measures. In the event of the COVID-19 pandemic enterprises were not prepared for such threats. Therefore, an important role is played by the health and safety inspector who should be involved in the company management process. The impact of the safety aspects of the work environment on the quality and efficiency of work is even more important in the event of an unexpected hazard that is difficult to completely eliminate. The purpose of the paper is to present the causes and effects of the COVID-19 biohazard according to the Ishikawa diagram on the example of a selected process in an enterprise.

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.

Product quality management refers to a set of activities, which allow checking the product quality and eliminating any inconsistencies. In eliminating incompatibilities its necessary to identify their root causes. It is possible by using the selected quality management techniques. As it was shown, it is very useful after analyses the incompatibilities identified by popular non-destructive tests (NDT), which are used to check an incompatible product. It was concluded that practice quality management techniques after NDT are necessary because NDTs are effective in finding incompatibilities in the product (without its destruction) but not identifying their causes. The aim of the study was the analysis of using the selected quality management techniques (Ishikawa diagram and 5Why method) to identify the source of the porosity which was detected by the fluorescent method. The problem was identified in an enterprise localized in the Podkarpacie region. But after identifying the incompatibility in the product, no further analyses to find the root cause of the problem occurrence were made. After the NDT (fluorescent inspection method) on the product (made from 410 steel) used in the aviation industry, the porosity was identified. Because the root cause of porosity was not known, the sequence of the Ishikawa diagram and 5Why method was used. These methods were used in an adequate way (first the Ishikawa diagram and second the 5Why method) because only in this way it is possible to find the root cause of the problem. By the Ishikawa diagram, the potential causes and two main causes (i.e. inadequate preparation, water in molding sand) were identified. The source of the porosity (contaminated material) was found through the 5Why method. It was concluded that the selected quality management techniques (Ishikawa diagram and 5Why method) were useful in finding the root cause of the porosity of the product. Additionally, the paper proposed the use of the Ishikawa diagram and 5Why method after the NDT test, and this sequence was effective in finding the root causes identified by NDT tests, so it can also be used to solve other problems with incompatibilities.

Występujące w przedsiębiorstwach niezgodności wyrobów powinny być analizowane w efektywny sposób, tak aby możliwe było zidentyfikowanie źródła powstania tych niezgodności. Jest to możliwe za pomocą odpowiednio dobranej sekwencji technik zarządzania jakością. Sekwencją tą jest diagram Ishikawy i metoda 5Why. Celem pracy było przeanalizowanie niezgodności wyrobu (wada płyty meblowej) i wskazanie źródła jej powstania za pomocą sekwencji technik: diagramu Ishikawy i metody 5Why. Problem z niezgodnością w płytach meblowych zidentyfikowano w przedsiębiorstwie zlokalizowanym na Podkarpaciu, w którym produkowano meble i fronty meblowe. Wybór niezgodności dotyczącej wady płyty meblowej uwarunkowany był częstotliwością występowania problemu (ponad 470 sztuk płyt meblowych/9 miesięcy). Z kolei dobór sekwencji technik diagramu Ishikawy i metody 5Why wynikał z ich potwierdzonej skuteczności do analiz niezgodności wyrobów w ramach wskazania źródła ich powstania. Za pomocą diagramu Ishikawy określono potencjalne przyczyny niezgodności dotyczącej płyty meblowej, spośród których wskazano trzy przyczyny główne (wyeksploatowana maszyna, złe magazynowanie oraz złe układanie płyt meblowych na paletach). Kolejno, za pomocą metody 5Why zidentyfikowano źródło analizowanej niezgodności (tj. zła organizacja pracy, brak okresowych TMP maszyny), po czym zaproponowano działania doskonalące. Zaproponowana sekwencja technik diagramu Ishikawy i metody 5Why może być praktykowana w innych przedsiębiorstwach zarówno do analiz różnego rodzaju wyrobów, jak i niezgodności.

The incompatibilities of products that are occurring in enterprises should be analyzed in an effective way, so as to could identify the root of occurred these incompatibilities. It is possible by adequate selected sequence of quality management techniques. This sequence is the Ishikawa diagram and 5Why method. Therefore, the aim of the work was to analysed the incompatibility of the product (defect of furniture board) and identified the root of it occurred by using the sequence of the Ishikawa diagram and 5Why method. The problem with the incompatibility of furniture board was identified in enterprise localized in Podkarpacie, in which the furniture and furniture fronts were produced. The choice of incompatibility of the furniture board was conditioned by the frequency of occurred the problem (above 470 pieces of furniture boards/9 months). In turn, the selection of the technique sequence of the Ishikawa diagram and 5Why method was resulted from their proven effectiveness to analyze of incompatibilities of products as an indication of the source of their origin. By the Ishikawa diagram the potential causes of incompatibility of furniture fronts were identified, from which the three main causes were selected (worn out machine, bad storage, an incorrect arrangement of furniture boards on pallets). Subsequently, the source of the incompatibility was identified using the 5Why method (i.e. poor work organization, no periodic TMP machines), after which the improving actions were proposed. The proposed technique sequence of the Ishikawa diagram and 5Why method can be practice in other enterprises to analyze different types of products and incompatibilities.

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.

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.

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.

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.

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.
