The emergence of digital technology is a paradigmatic historical change. As a process of transforming social engineering structures, digitization has had a ubiquitous impact on the organization of structures and business logic, as well as on economic principles and rules. The fertile ground for digital technology applications is logistics management, which manifests itself in the dynamic development of logistics 4.0. Increasingly, it is pointed out that digital technology has some distinct features that have fundamental implications for innovation. The aim of the present study is to determine the impact of the risk of implementing digital technologies for logistics management. The study was conducted using the standardized questionnaire interview method with representatives of the management of enterprises. The attempt was random. The sampling was made up of micro, small, medium, and large enterprises from the production and services sectors, having a logistics unit or a logistics division, located in the “Bisnode Poland” database. In total, 360 full interviews were carried out. For the study, we defined macro-environment, operational, functional, and microenvironment risks. The basic conclusion is that between each type of risk and the type of digital technologies used in the studied entities and their partners in the supply chain, there is a high and very high dependence in the case of three-dimensional printing (3D printing), artificial intelligence, blockchain, drones, augmented reality, and self-propelled vehicles.

The impact of the space development structure on the level of the ecological footprint is an important element of the sustainable development policy, determining not only its directions, but also indicating the manner of respecting environmental principles. The aim of the research is to assess the impact of the spatial development structure on the ecological footprint level. The considerations are based on the assumption that the spatial development structure is a determinant of the ecological footprint level. The study used the shift share analysis method. Selected European countries were the subject of the research. The research period covered the years 2009-2019. The spatial differentiation of the GDP level and the ecological footprint were compared. For each country, the components of structural changes were determined and their changes over time were assessed. The study positively verified the main hypothesis and the auxiliary hypothesis. The ecological footprint decreased in the analyzed period. This phenomenon was not evenly distributed in European countries. Regions with a higher level of changes in the phenomenon than the EU average can be distinguished. The greatest changes in the demand for biosphere' natural resources in hectares of land and sea were recorded in Latvia and Lithuania. In contrast, the largest decrease in the size of the ecological footprint was observed in Cyprus. Differentiation of changes was visible within the individual components making up the ecological footprint in the analyzed period. The biggest changes took place within the fishing grounds. The smallest changes were recorded for cropland. This paper is expected to provide policy makers with a set of policy proposals to achieve sustainable environmental and economic development.

The article is a contribution to the discussion on the possibilities of effective logistic decisions under the conditions of uncertainty. Variable and unpredictable factors, which create the conditions of uncertainty, not only directly affect logistic processes (positive or negative impact), but can also be a determinant of making decisions. Logistics management, because it is referred to in the context of decision-making, is currently defined by the quality of management decisions taken, including factors which often constitute only partially quantifiable sets. The main goal of the article is to show the strength of the dependence between the occurrence of uncertainty factors and the type of decision. On the basis of decision-making theory, the types of decisions were defined, and then a set of factors that are most important for a given type of decision was selected. The results of the analysis allowed the strength of the influence of uncertainty factors on making logistics decisions to be determined. On this basis, a catalog of key decisions was selected, including decision types, and also the effects of decisions taken under uncertainty were determined. The study and the results of the analysis should be treated rather as a voice in the ongoing discussion. Due to the unpredictability of some uncertainty factors, the research field in the discussed problem remains open.

The article aims to present the assumptions and results of the first part of the initial research of logistic management in conditions of uncertainty. As a result of the research, research gaps were identified which determine further directions of research in the problem above. The presented research results were analyzed using the statistical method of Spearman and Guilford, which allowed verifying the assumptions and determining the working version of the hypothesis and the partial purpose of further research. The evaluation of the survey results confirmed the need for conducting in-depth research in recognition of uncertainty conditions at the strategic management level.
