The paper presents one of the tasks of logistics which refers to analysis and decision support making for performance measurement devices. Provide quality of the product comes down to continuous control of the degree of defective production stands and for this reason MSA measurement systems analysis may prove to be an effective tool. The need to analysis of measuring devices (systems) is visible also in the area of logistics. Article performs two experiments R&R(real and simulated data). Sample was measured multiple times by 4 operators. The most important result of R&R analysis is a graphical plot of the variability of results. The percentage of tolerance defines the evaluation of the functioning measurement system, taking into account variation of the part, variation of the measurement device and variation of operator. The paper discusses the process of measuring the thickness of the material used for packaging food products (films) and its characteristics. It describes the purpose and objective R&R analysis and also outlined the types of errors that can significantly affect the reliability of results which can be the persuasive information in the decision process. The study showed that consequently determining the capability of the measurement system is important aspect of quality and it may contribute to a significant reduction in the risk of claims and costs deficiencies.

Celem pracy jest wykonanie możliwie szerokiej analizy danych zgromadzonych podczas badania pojazdów. Artykuł uzupełniono o materiał statystyczny dotyczący poziomu bezpieczeństwa i wypadkowości na drogach w obrębie krajów UE oraz ocenę sytuacji Polski na tym tle. Dokonano również porównania niektórych wskaźników. Analizy przygotowano w programie STATISTICA i Microsoft Excel.

The aim of this paper is to explore the data collected during vehicle inspections such as the analysis of brand and age of controlled cars and others. Data was also used having been obtained by the Central Statistical Office of Poland. This statistical material concerned car safety and also road traffic accidents within the EU member states. Comparisons were also made between accident and mortality rates. Analy-sis was performed using STATISTICA and Microsoft Excel.
