The aim of the work is to change the current program in the programmable logic controller (PLC) to be as close as possible to the real-world Pick to Light system in the automotive industry for installing individual car components. The change consists in completing the navigation and tutorial mode while preserving the original function of the program, which is to measure the time of each step in assembly of the components and the reading of the pieces from the trays. A simple virtual laboratory model was created which enables to test the program even if the access to the PLC and HMI panel is not possible. The partial goal was to modify the visualization of the program in the operator touch panel Human – Machine Interface (HMI). Another partial goal was to implement a new PLC program. In order to better understand the created program, the flowcharts were created and described for the main parts of the program.

Za pomocą metodyki wykorzystującej wybrane techniki zarządzania jakością przeanalizowano i scharakteryzowano ważną i powtarzającą się wadę w nadruku farby, jaką była nieciągłość farby na nadrukach etykiet z PVC w jednej z podkarpackich drukarni wykonującej nadruki techniką tampodruku, oraz zidentyfikowano przyczyny tej nieciągłości. Zastosowano metodykę składającą się z kolejno wykorzystanych: metody 5W2H i diagramu Ishikawy. Dla ustalonej w ten sposób przyczyny głównej wykonano następnie analizę z wykorzystaniem metody 5Why. Zaproponowany sposób przeprowadzenia analizy, wykorzystujący wymienione i zastosowane w odpowiedniej kolejności instrumenty zarządzania jakością, okazał się być adekwatną metodyką rozwiązania problemu występowania nieciągłości farby na wydrukach.

The cause and effect diagram (Ishikawa diagram) and 2 other methods based on answers to questions about the course of the technol. process were used sep. to det. the reasons for discontinuities of printing on PVC labels. The defects resulted from the lack of instructions for mixing paint components.

The research presents the measurement of vibrations on KUKA industrial robot and their subsequent evaluation. The work first deals with vibro-diagnostics and its position in the field of maintenance and then discusses the issue of its use in monitoring the status of industrial robots. The practical part describes the performance and analysis of the vibration measurement in order to assess the possibilities of applying the vibrodiagnostics in assessing the state of a robot during operation.

The study deals with the topic of evaluation and comparison of environmental efficiency and efficiency of health care systems in the V4 countries during the period from 2009 to 2017. The uniqueness of this study lies in the comparison of two different types of efficiencies and in the selection of the object of research. The aim of this paper was to examine the possible relationship between environmental and health efficiency in the V4 countries and to reveal the common determinants of these efficiencies. We implemented the method of two-step Data envelopment analysis, in which, we determined the values of input CCR and BCC health and environmental efficiency in the first step and then in the second step, we used the method of truncated regression to verify the effects of selected determinants of computed efficiencies in V4 countries. Based on these analyses, we found that although there is no significant relationship between the values of health efficiency and environmental efficiency, some determinants significantly affect both types of efficiencies.
