Purpose: The aim of the article is to examine the reasons why organizations do not use the information obtained in the audit process. Design/methodology/approach: For the realization of the work we used the results of our own research of organizations that have certified quality management systems for compliance with the requirements of ISO 9001. The information obtained relates to organizations operating in the territory of Poland. Findings: Organizations conducting quality management system audits acquire a variety of information that should be used for management purposes. Some organizations have serious problems with acquiring data and processing it, and using the information for decision-making and improvement-oriented activities. The paper identifies 10 potential reasons why organizations do not use information from the audit process. A comparison was made between the causes found in internal and external audits. An analysis of each of the identified causes was carried out, paying attention to their origins. Attention was paid to the connections between the causes. Directions for eliminating problems were indicated. Practical implications: The results obtained have practical application. Organizations with an awareness of the causes of problems are able to take, both corrective action and preventive action. In the first case, it is about taking corrective actions to existing problems. In the second case, it is about preventive actions, which should prevent a problem from arising. Social implications: The results obtained have social implications. They draw attention to the need to build a pro-quality and improvement-oriented awareness. Originality/value: The article for the first time identifies the causes of problems arising in organizations in the context of the use of audit information. Attention is paid to the mechanism of disorders and ways to eliminate them are indicated. The article is especially recommended to the top management of organizations that conduct system audits.

Purpose: Critical defects are of great significance when evaluating the production process effectiveness, especially in the automotive branch. It is important to analyse these defects and distinguish the crucial ones. In this article, the authors have identified critical defects in the process of brake master cylinders production using quality management tools, and proposed improvement actions. Design/methodology/approach: The aim of the article was to analyse defects and the reasons for their occurrence, and improve the production process of master cylinder with special attention to critical defects. In order to improve this process, critical flaws had to be identified and eliminated from the entire set, which was the engineering problem to be solved. Then the causes of their occurrence as well as the factors causing process disturbances affecting the final occurrence of the defect were identified, and actions eliminating or limiting their occurrence were proposed. In the project, they were used to analyse the tools and principles, i.e. process diagram, Pareto-Lorenz diagram, cause-effect diagram, and to improve the Poka-Yoke process. Findings: Based on the examined causes of defects, improvements were proposed, i.e. guides for applying the body, a program stopping the piston assembly station to control the oil level, purchase of caps from sealed material and the need to work in long-sleeved work clothing, moving the body type verification camera from the final to first station, pallet spacers to protect against piston damage, change of supplier, especially of body castings. Research limitations/implications: The major limitation of the paper is that it is based on one case of an organization. In the future, it will be necessary to conduct studies in more organizations so as to find out if the same result can be achieved. Originality/value: Until now, no quality management tools have been used to analyse and organize the formation of defects in production processes.

The article describes the process of analysing and improving the rolling stock repair. The problem was ineffective qualification of additional works and elements to be replaced in the renovated wagons. The qualification is carried out before undertaking the repair activities. Improper qualification increases the cost of renovation and, in consequence, causes the customer to incur additional expenses, which lowers their trust in the enterprise. The aim was to reduce the number of elements qualified for renovation and, thus, lower the unplanned costs and the wagon repair time. Major problems involved in the process of qualification were identified and, owing to the use of the SD method, corrective and preventive actions were prepared and undertaken. The last stage consisted in the verification of the results obtained.

The objective of this study was to determine the suitability of the nanofiltration (NF) process to recover the regenerating agent (NaOH) from spent solutions contaminated with organic compounds. NaOH recovery from 2 spent regenerant solutions after cleaning ultrafiltration (UF) membranes (polymeric 30 kDa, ceramic 300 kDa) fouled with natural humic water was carried out using 2 types of NF membranes: NP010P (Na2SO4 rejection: 35–75%) and NP030P (Na2SO4 rejection: 80–95%). It has been shown that the use of the NP030P membrane allows for very high separation efficiency of organic compounds (up to 97% of color intensity reduction) from the tested solutions. It was also observed that the effectiveness of the process, in addition to the type of membrane used, also depends on the time of NF process – along with the elapsed time of the process, the hydraulic and separation properties of the tested membranes deteriorated. The obtained results showed that the use of both tested NF membranes allows for the recovery of NaOH to a degree that allows its re-use.

W przeprowadzonych badaniach określono przydatność procesu nanofiltracji (NF) do odzysku czynnika regenerującego (NaOH) z roztworów poregeneracyjnych zanieczyszczonych związkami organicznymi. Uzyskane wyniki pokazały, że użycie obu testowanych membran nanofiltracyjnych (NP010P oraz NP030P) pozwala na odzysk NaOH w stopniu pozwalającym na jego ponowne użycie. Wykazano, że zastosowanie membrany NP030P pozwala na uzyskanie bardzo wysokiej skuteczności separacji związków organicznych (do 97% usunięcia barwy) z testowanych roztworów. Zaobserwowano również, że skuteczność procesu, oprócz rodzaju użytej membrany, zależała także od czasu prowadzenia nanofiltracji – wraz z upływającym czasem procesu pogarszały się właściwości hydrauliczne i separacyjne testowanych membran.

This paper presents a method of improvement of the accuracy in natural frequency determination when having impulse responses from impact testing. A new method is used for obtaining impulse response spectrum. The improvement in natural frequency determination is a result of improving the spectral resolution. For this, the new method uses calculation of surface area under the envelope of the cross-correlation function. This process is repeated by single-harmonic signal generated step-by-step with frequency changed iteratively. Thus the frequency resolution of determined spectrum is independent of length of analysed impulse response.

Poprawa wyznaczania częstotliwości drgań własnych jest wynikiem poprawy rozdzielczości widmowej. W tym celu nowa metoda wyznacza pole powierzchni pod obwiednią funkcji korelacji wzajemnej. Proces ten dokonuje się cyklicznie włącznie z generacją fali harmonicznej krok po kroku wraz z iteracyjną zmianą jej częstotliwości. W ten sposób, rozdzielczość częstotliwościowa wyznaczanego widma jest niezależna od długości analizowanej odpowiedzi impulsowej.

The article presents identification of problems during the implementation of Lean concept in small and medium-sized enterprises in Poland. Although the Lean methodology is recognized all over the world as one of the best and most effective ways to improve the functioning of enterprises, in Polish conditions exist serious problems with its implementation. Development of small and medium-sized enterprises is regarded as one of the measures of economic growth and a sign of healthy competition. The needs of the economy and the limited resources characterizing this enterprise sector imply the need to adjust its capacities to the requirements of the turbulent environment. In the analysis of problems there were used the results of questionnaire surveys conducted among representatives of the companies participating in the largest Lean conference in Central Europe.

Poniższy artykuł stanowi próbę spojrzenia na problem akustyki przez pryzmat wymagań energetycznych. Autorzy spróbowali określić na ile wymagania dotyczące dźwiękoizolacyjności i energooszczędności są zbieżne a na ile stoją w sprzeczności względem siebie. W artykule przypomniano krótko zależność pomiędzy izolacyjnością cieplną a dźwiękoizolacyjnością ścian. Przedstawiono zależności pomiędzy izolacyjnością akustyczną właściwą wyrażoną wartością wskaźnika RA2 współczynnikiem przenikania ciepła U a także masą powierzchniową przykładowych szyb zespolonych. Przedstawiono także wyniki badań prze prowadzonych w Laboratorium Wydziału Budownictwa Politechniki Śląskiej dotyczące poprawy izolacyjności akustycznej właściwej ściany z systemem izolacji ETICS, systemem „tradycyjnym” a także systemem izolacji lekkiej suchej. Przedstawiono wykres izolacyjności akustycznej właściwej w funkcji częstotliwości dla kolejnych pasm 1/3 oktawowych w zakresie od 50 do 5000 Hz. Analiza wykresów izolacyjności akustycznej właściwej Rw oraz poprawy izolacyjności akustycznej właściwej ΔRw w funkcji częstotliwości, jednoznacznie wskazuje na przyczynę niekorzystnego wpływu systemu ETICS wynikającą z przesunięcia częstotliwości rezonansowej w kierunku wartości średnich wynoszących od 200 do 400 Hz. Jednocześnie na podstawie wyników badań stwierdzić należy pozytywny wpływ ocieplenia wykonanego systemem „tradycyjnym” a także w technologii lekkiej suchej. Na podstawie przedstawionych w artykule wyników badań stwierdzić należy, że rozwój technologii wykonania obiektów zmusza uczestników procesu budowlanego do dokładniejszego zapoznania się z problematyką akustyki budowlanej. Przyjęcie rozwiązań materiałowych i konstrukcyjnych o dobrych parametrach cieplnych nie daje żadnych gwarancji osiągnięcia dobrych paramentów dźwiękoizolacyjnych przegród.

The following article is an attempt to look at the acoustic problem from the perspective of energy requirements. The authors attempted to determine whether the sound requirements go hand in hand with energy efficiency. Or on the contrary they are contradictory. The article recalls the relationship between the thermal insulation and sound insulation of walls. Authors presented; the relationship between the value of the index RA2 and the heat transfer coefficient U of insulating glass units, the relationship between the value of the index RA2 and the surface weight of insulating glass units. The article presents the results of research implemented in the Laboratory of the Department of Civil Engineering of Silesian University of Technology for improvement of sound reduction index by ETICS and the another thermal insulation systems ("traditional" and light dry system). The paper also contains a graph of airborne sound insulation as a function of frequency for one-third octave band values for 50 to 5000 Hz. Analysis of these graphs gives the answer about the reason a reduction in sound insulation for walls with ETICS. Shift of the resonance frequency in the direction of the average values 200 ÷ 400 Hz is causing the reduction. Traditional and light dry system does not give such a negative effect. On the basis of research results in the article, it should be noted that the development of technology makes the adoption of materials with good thermal performance does not guarantee parameters of sound insulation walls. All that forces the participants in the construction process must be thoroughly familiar with the problems of building acoustics.

Vol. 79, nr 2

53--59

EN

Purpose: Dynamic recovery is interesting as it limits the maximal deformation strength of crystalline materials. Due to its small grain size, nanocrystalline Ni reaches its maximal strength after small strains < 0.1. It is shown that dynamic recovery contributes to strain and that its kinetics differs from that of hardening strain. Design/methodology/approach: The kinetics of recovery was studied by performing a large stress reduction suppressing thermally activated glide of the hardening type. The transition to a new quasi-stationary state at reduced strain rate and stress was accelerated by incremental increases of stress. Findings: During the transition the kinetics of deformation changes from that of recovery strain to the quasi-stationary one where hardening and recovery are coupled. The results are interpreted in terms of thermally activated hardening strain (in the grains) and thermally activated recovery strain (boundary mediated) linked by internal stresses. The activation volume of the hardening strain rate determined from the small stress increments is not inconsistent with the classical theory of thermally activated dislocation glide. Research limitations/implications: It is proposed to better characterize dynamic recovery by performing small stress changes in the period of dominating recovery strain to quantify the kinetics parameters of recovery strain. Practical implications: Disturbing deformation by sudden changes of stress is recommended as a suitable means to describe the kinetics of dynamic recovery. Recovery strains should enter the modeling of plastic deformation. This holds in particular for cases where dynamic recovery is prominent, e.g. at high stresses, high temperatures, and variable stresses (cyclic deformation, stress relaxation). Originality/value: The stress change method described in this work is generally applicable in deformation testing independent of the type of testing machine, where inelastic strains are measured at the usual accuracy.

We have studied the time-dependent mechanical behaviour of binary textile compound systems of textile fabrics assembled or fused together, including stress-strain relations, creep and creep recovery, as well as the redistribution of tension on single components under a constant total load. The fabrics and systems discussed in this study are characteristic for the manufacture of garments. A relaxometer with digital specimen tension and elongation meters was developed with the purpose of more precisely defining the starting points of creep and creep recovery processes of fabric systems, and to measure the tension of single components within the fabric system. We have also studied the influence of the adhesive interconnection of the components in fusion on the stress-strain relations and creep recovery behaviour of the fabric systems. It is shown that at constant total load on assembled textile fabric systems, the single components of the system undergo very different partial tensions - the greater tension falls on the component possessing the higher modulus. It is further shown that tensions on the single components are redistributed over time.

Badano zmienne w czasie właściwości mechaniczne binarnych kompozytowych systemów płaskich wyrobów włókienniczych, połączonych lub spojonych ze sobą. Mierzono zależności naprężenie-odkształcenie, pełzanie i relaksacje pełzania, jak również redystrybucje naprężeń na poszczególne składniki kompozytu pod działaniem stałej siły. Tkaniny i dzianiny, jak i ich kompozyty omawiane w tej pracy, są charakterystyczne dla produkcji ubiorów. Opracowano specjalny relaksometr z cyfrowymi miernikami naprężeń i wydłużeń próbki, dla bardziej precyzyjnego określenia początków procesów pełzania i relaksacji kompozytów oraz pomiaru naprężeń pojedynczych komponentów w obrębie systemu. Badano również wpływ połączeń klejowych na przebiegi naprężenie-odkształcenie oraz relaksację pełzania testowanych systemów. Wykazano, że przy stałym obciążeniu systemu połączonych płaskich wyrobów włókienniczych, poszczególne komponenty systemu podlegają bardzo zróżnicowanym naprężeniom, przy czym większe naprężenia występują w komponencie o wyższym module sprężystości. Wykazano również, że redystrybucja naprężeń na poszczególne komponenty przebiega w czasie.
