When observing e-commerce, it can be concluded that parcel lockers are an innovative solution to the everyday challenges faced in logistics. The fast pace of life and traffic congestion make parcel delivery difficult and expensive, while parcel lockers offer a more efficient way to receive and send packages 24/7. Key advantages include reduced delivery costs, environmental benefits (less CO2 emissions), security of packages and greater availability to users. Parcel lockers are making access easier, while couriers can optimize their delivery routes. In this research, using the FUCOM (Full Consistency Method) and MARCOS (Measurement Alternatives and Ranking According to the Compromise Solution) methods, a model for selecting optimal locations for installing parcel lockers of the X-Express company for the Vitez distribution center was developed. The first step is data collection, while multi-criteria decision-making methods enable detailed analysis and ranking of potential locations. The introduction of parcel lockers contributes to the modernization of logistics, reduces administrative tasks and supports environmental sustainability.
