The article presents data on the number of passengers transported by domestic and international passenger air transport in the United States on a monthly basis in the years 2003–2020 and their forecasting for 2021. The research began with the analysis and evaluation of two time series concerning the number of passengers transported by passenger air transport in the United States in terms of national and international approach. The Klein model was built, which was used to forecast the time series of the number of passengers transported by domestic air transport on a monthly basis for the year 2021. The constructed model is a combination of quantitative and qualitative forecasting.

The objective of the article is to carry out a multidimensional comparative analysis of populations and human deaths in European countries in terms of economic security. The research applies tools of comparative analysis, first by grouping and unraveling the data and then by their charting and evaluation. The study covers 32 European countries focusing on populations and deaths of people in 2005–2018. The research question has been formulated as: "Will the application of multidimensional comparative analysis of populations and deaths of people in 32 European countries allow to detect any regularities occurring in the phenomenon?"

The article provides multidimensional comparative analyses of dependent variables (32 European countries, years) and explanatory variables (population and human deaths) in terms of the impact on economic security. The results of the studies carried out are repetitive relationships in mononomial intervals — years.

Detecting regularities persistent in populations and human deaths in 32 European countries using multidimensional comparative analyses may allow their predicting in the future. Death rates expressed in percentage points in populations of 32 European countries in 2005–2018 were calculated and enabled observation of similarities in the time series analyzed.

The article discusses the problem of analysis and evaluation of income data and its forecasting for 2019 in the selected company. A lot of research tools were used to analyze the primary time series. They allowed to observe trends in the form of a downward trend and seasonality on a monthly basis. The detected trends were examined by applying further research tools, and by building a threeway multiple regression model. The assessment of the conducted analyzes is unequivocal confirmation of the existence of the trend and seasonality on a monthly basis in the primary time series. It became a direct premise to perform the prediction of the primary time series as a result of the critical analysis of literature and personal experience by means of the Holt-Winters exponential smoothing method.

Keywords: revenues; forecasting

The article deals with the problem of using IT tools to manage inventory at BMW Poland. The aim of the paper is to improve inventory management in the analyzed company by implementing the SRD tool. The research began with the analysis of the research problem in the light of the literature of the subject of research. Then, the indicators used during inventory management in the surveyed company were analyzed and evaluated. The method of comparative analysis was used for assessment, where indicators before and after the implementation of a new inventory management tool in the research entity (2018–2019) called SRD were compared.

In this article the author raises the issue related to the multidimensional analysis and its evaluation of data concerning the price of one square meter of a flat in Poland. The research was conducted in three stages. During the first stage, the analysis and evaluation of original time series were done in relation to the price of one square meter of living space in Poland dynamically. During the second and third stage of the multidimensional analysis, the grouping of data was done. The grouping variable comprised years, quarters and on the basis of them the analysis and its evaluation were conducted. The conducted evaluation of multidimensional analysis is a premise for the choice of forecasting method for the future.

Keywords: outlays/amounts; flat price; multidimensional analysis
