Test statystyczny sprawozdaj?cy hipotez? dobroci pearsona

W artykule dotycz?cym metod i technik prognozowania warto?ci kluczowych wska?nik?w efektywno?ci obs?ugi (ang. Key Performance Indicators) zdefiniowano oraz sklasyfikowano te wska?niki. Przedstawiono wymagania oraz spos?b doboru wska?nik?w KPI. Dokonano przegl?du, a tak?e scharakteryzowano metody i techniki prognozowania stanu organizacji utrzymania ruchu. Przedstawiono koncepcj? wykorzystania wybranych metod oraz narz?dzi gromadzenia oraz przetwarzania danych dla potrzeb prognozowania tego stanu. Study deals with an analysis of data to the effect that it improves the quality of statistical tools in processes of assembly of automobile seats. Normal distribution of variables is one of inevitable conditions for the analysis, examination, and improvement of the manufacturing processes (f. e.: manufacturing process capability) although, there are constantly more approaches to non-normal data handling. An appropriate probability distribution of measured data is firstly tested by the goodness of fit of empirical distribution with theoretical normal distribution on the basis of hypothesis testing using programme StatGraphics Centurion XV.II. Data are collected from the assembly process of 1st row automobile seats for each characteristic of quality (Safety Regulation -S/R) individually. Study closely processes the measured data of an airbag?s assembly and it aims to accomplish the normal distributed data and apply it the statistical process control. Results of the contribution conclude in a statement of rejection of the null hypothesis (measured variables do not follow the normal distribution) therefore it is necessary to begin to work on data transformation supported by Minitab15. Even this approach does not reach a normal distributed data and so should be proposed a procedure that leads to the quality output of whole statistical control of manufacturing processes.
