Opis:
Purpose: The main purpose of the paper is to apply the TOPSIS method for selecting the optimal contractor for a passenger transfer center. Methodology: The methodology is based on the use of TOPSIS, which determines the distance of decision alternatives from the ideal and anti-ideal solutions using evaluation criteria. Results: Two different contractor rankings were obtained depending on the weights of the criteria. With equal weights, the best contractor is number 5, while with weights determined by formula (8), the best is number 4. Theoretical Contribution: The paper contributes to the field of investment project management by demonstrating how the TOPSIS method can aid in decision-making for optimal contractor selection, thereby reducing the risk of erroneous decisions. Practical Implications: The practical implications of this research are significant for investment projects, as the demonstrated methodology can be directly applied to the contractor selection process, potentially leading to more successful project outcomes.

Opis:
Safety in aviation has various connotations. According to the International Civil Aviation Organization (ICAO), it is a state in which the possibility of harm to people and property is minimised and maintained within a continuous process of identifying threats and managing safety risks at an acceptable level or below an acceptable level. Actions related to threat identification can be reactive, proactive, or predictive. Reactive actions aim to verify what happened, why, and how to prevent it from recurring. For this purpose, incidents that occurred in the past are analysed. By Polish law, the Commission for Investigating Aviation Accidents investigates accidents and serious incidents, while incidents mostly fall under the responsibility of the aviation organisation in which the incident occurred. Therefore, this article aims to identify threats causing incidents. Three thousand two hundred aviation incidents reported between 2017 and 2022 to the Civil Aviation Office as part of the mandatory and voluntary event reporting system were analysed. The identified causes, due to the diversity of their description, were divided into four groups. The first group consists of human factors, representing inadequate actions by pilots, crews, or individuals who caused a situation of danger. The second group comprises errors in the operation of technical objects, including aircraft. This group also includes situations where foreign objects violate airspace or minimum conditions are breached. The next group includes environmental causes such as wild animals, birds, and weather conditions. The last group consists of procedures related to flight phases.

Opis:
For many years, the amount of waste generated on a global scale has shown an increasing tendency and their management and logistic is becoming a growing problem for most countries in the world. Waste management is an important issue to be addressed, as it concerns the three basic pillars of sustainable development: social, economic, and environmental. Therefore, it seems necessary to take initiatives to reduce the amount of waste generated and improve the waste management system. The article aims to analyse changes in the way of waste management and logistics in the European Union countries and the classification of these countries on the basis of the achieved effects in waste management. The article analyses three selected factors that reflect the effects of achieving environmental objectives in waste management. The cluster analysis method was used for the analysis. It found that EU countries differ in the quality of the results achieved in waste management, depending on the achievement of environmental management and sustainability objectives. In addition, the results of the analysis showed that the time factor has a significant impact on the classification of countries. High dynamics of the quality of effects in waste management were observed in the period under review.
