“…The effect of this scientific "anguish" has become a relatively simple tool, supporting decision-makers in making complex decisions [48]. In addition to numerous recommendations from other researchers [49,50,51,52], as well as flexibility and universality, this very advantage of the AHP method and the possibility of author's adaptation to the specific test conditions, decided on its choice for the purposes of this study.…”

Forestry and the wood-based sector, including the wood industry, which is an important element of economic systems and a source of budget revenues for many countries in the world, found itself in the first quarter of 2020 in a situation of a serious threat of a prolonged crisis as a consequence of the pandemic. In this perspective, it is necessary to review existing sector strategies and look for new solutions to ensure first survival, then functioning and finally development of entities forming the wood market. In the scientific research, which is the subject of this work, an attempt was made to multi-criteria analysis of the selection of the optimal anti-crisis strategy for actors from forestry and the wood-based sector in the face of a pandemic. Preparatory studies were conducted on the example of Poland, where both forestry and the wood industry belong to the dominant sectors of the economy, conducting them at the turn of March and April 2020. The research was referred to the primary wood raw material market in Poland, which is the main link in the value chain, created first by the dominant owner: Państwowe Gospodarstwo Leśne "Lasy Państwowe" - the “State Forests” National Forest Holding (SFNFH), and then forest service entrepreneurs, to entities representing the wood industry. The work uses a concept modified for the purposes of the author's research scenario, based on the method of multi-criteria hierarchical analysis AHP (Analytic Hierarchy Process). The best possible decision was to be searched that would allow the selection of the optimal anti-crisis strategy for enterprises - actors of the sector concerned. Based on the collected results and their expert discussion, recommendations for sectoral policy for forestry and the wood-based sector were then formulated. The proposed solutions are located against the background of a dispute between the concept of institutional intervention and a model taking into account the effects of market factors. The work is both cognitive (optimization and adaptation of the research method) and practical up-to-date. An accurate development strategy for forestry and the wood-based sector is urgently needed and necessary to implement as quickly as possible.

The study examines the possibility of applying the selected components of the theory of six value aggregation paths in designing walking pathways. Based on spatial data collected using a landscape assessment method on the aesthetic values of the landscape of the place under analysis, a model was developed of the network of links of the landscape aesthetic value using a minimum increase in this value. The authors designed scenarios for the optimal routes of walking pathways. The conducted study leads to the conclusion that the minimum value increase path may create a good basis for designing walking pathways. Not only is this manifested in the varied route of the pathway, but also in it being designed in such a way that the landscape’s aesthetic value increases beyond an assumed level of aesthetic value. In addition, the use of hexagonal basic fields enables the design of various route lengths and the optimization of time by adapting the model to a specific group of recipients.

Simultaneous use of data repeated levelling measurements and continuous GNSS observations allows increasing the spatial resolution of geodynamics models. For this purpose, it is necessary to create a single network, a so-called hybrid network. This paper aims at examining the possibility of using scale-free network theory to determine the most relevant common points in hybrid networks using the distance criterion. Used on European network points: UELN (United European Levelling Network) and EPN (European Permanent GPS Network) and the regional network. In the hybrid network (UELN + EPN), 18 pseudo-nodal points with the highest number of links were identified. The accepted distance criterion shows that about 90 % of the EPN points can be used as common points. The application of the scale-free network theory allows determining the significance of points in a hybrid network.
