Background: With their high speed and low response time, unmanned aerial vehicles (UAVs) have been suggested as a solution to overcome the systematic inefficiencies in the current vaccine cold chain of Sri Lanka. The implementation of unmanned aerial systems (UASs) at the district level is recommended to maintain the end-to-end effectiveness of the program. Under the suggested distribution network, vaccines are transported directly from the Regional Medical Supplies Division (RMSD) warehouse to the respective health facilities, bypassing the Medical Officer of Health (MOH) unit warehouse. However, the use of UAVs is not appropriate in every RMSD due to the high fixed cost of a UAS. Methods: To determine an appropriate division, a suitability analysis was conducted by intersecting eight factors with their weights of importance. Suitable factors were determined using previous literature and weights of importance were calculated by an expert survey. Results: From the analysis, it was determined that the Kurunegala division is the most appropriate for UAV implementation. Therefore, Kurunegala is recommended as a starting point for the implementation of the proposed UAV-inclusive delivery system in Sri Lanka to realize its potential benefits and practical implications. Furthermore, it was found that a uniform solution involving only UAVs offers greater advantages compared to a mixed solution involving both trucks and UAVs. Nonetheless, owing to limited technological expertise and resistance to change in low-income nations, it is advisable to begin with a mixed approach and gradually transition to a uniform strategy in the coming years. Conclusions: The newly developed random search algorithm for the cyclic delivery synchronization problem gives results that are close to those obtained with mixed-integer programming. The main advantage of the algorithm is the reduction in computing time, which is relevant to the utilization of this method in practice, especially for larger problems.

Parcel lockers seem to be a very interesting and innovative solution for any type of city, beneficial to both customers and online stores. Accounting for the growing number of B2C e-commerce customers, this measure significantly meets their needs. Moreover, this solution solves the challenges of last-mile deliveries, which are one of the major effects of heavy traffic of commercial vehicles in the whole city area. Recipients and senders of parcels through parcel lockers are the main generators of demand for this service. Hence, assessing their satisfaction and requirements is a key indicator of the development of this area. This work focuses on the efficiency of user parcel lockers and compares the situation in Italy, Poland, and Ukraine. This paper also presents an analysis of the already existing data on the satisfaction of parcel locker users, as well as the results of a study conducted among Ukrainian consumers for this work.

Society, companies and institutions are involved in a digital transformation that can be pervaded in various industries or sectors, and this also applies to communication, sales and distribution channels. The possibilities of e-commerce have also increased and world trade has been further developed. In 2020, more than two billion people bought goods or services over the Internet. Customer satisfaction depends on the solution of the last mile process, the method of picking up shipments as well as the time and place of picking up the shipment. The most common forms of off-premises delivery are automated parcel locker or machine (APM) and pick-up and drop-off delivery (PUDO). The aim of the paper is to analyse the level of the PUDO and APM network in European countries and in the V4 countries with regard to the size of the country and the population. For this purpose, it was necessary to focus on determining the population per 1 PUDO and the number of inhabitants per 1 APM in individual European countries and subsequently in the V4 countries. The obtained data were processed and recalculated in Excel. The results showed that within European countries the best values were achieved by Finland with 526 inhabitants per 1 PUDO and Spain with 188 inhabitants per 1 APM. Regarding the V4 countries, the Czech Republic achieved the best value in the case of inhabitants on PUDO with 729 inhabitants per 1 PUDO and in the case of APM Poland with 3,184 inhabitants per 1 APM.

The purpose of this research study was to explore drone technology and performance of retail logistics by offering academic and practical benefits, explaining the preceding, and recommending a research plan based on a conceptual framework for drone technology and performance of retail logistics. A literature review has been created to assist today's retail logistics managers and researchers in scrutinizing what has been previously researched and what needs to be explored. From the standpoint of retail logistics, the study adds to our knowledge of drone technology as it relates to the performance of retail logistics and the constraints of future research. This study utilized a systematic literature review to design a suggested conceptual framework for a research agenda on drone technology and performance of retail logistics. The research paper provides insights into deficiencies in the drone technology, along with performance of retail logistics literature. The research paper explicitly recommends exploring the drone technology as it relates to expected and actual performance of retail logistics. This article contributes to the literature in a number of ways. To begin with, it provides the first comprehensive succinct synopsis of the essential concepts in the drone technology and retail logistics. Second, the impact of retail logistics in the growth of the economy. Third, the application of drone technology in retail logistics. Fourth, unnoticed challenges in retail logistics are then exposed as ideas for potential research. Finally, the technique utilized to conduct the systematic literature review can be used as a model for prospective researchers when conducting similar research. Contemporary research is aimed at providing a research group that address the needs of adopting the current technology on the performance of retail logistics. For performance of retail logistics, the article presents a suggested conceptual framework for drone technology and performance of retail logistics.

Introduction/background: The article is devoted to the possibility of "last mile" deliveries by electric cars with a permissible total weight of up to 3.5 tons. Aim of the paper: The aim of this article is to determine whether, with the technology currently available from electric car manufacturers, it is possible to use these vehicles for "last mile" deliveries. Materials and methods: The article contains a literature study of industry publications and the most important legal acts in European Union and in Poland. At the same time, the available issues in the field of “last mile” deliveries and the currently available technology of electric cars were analyzed. Results and conclusions: As a result of research based on the adopted assumptions for the implementation of "last mile" deliveries and the technical parameters of the currently available electric vans, the article presents a newly developed simplified algorithm showing the relationships between the time and number of unloading in relation to the length of the delivery routes. At the same time showing that the currently available technology of electric cars allows for the implementation of this process with their use.

Rozwój rynku B2C w handle elektronicznym wpływa na wzrost znaczenia dostaw ostatniego kilometra, realizowanych na terenach miast. Ze względu na specyfikę handlu-elektronicznego, funkcjonowanie dostaw w ramach e-commerce na rynku B2C oparte jest na dostawach domowych. Z powodu rosnącego popytu na te dostawy, który w konsekwencji może oddziaływać na ruch drogowy i problem kongestii, jak również na środowisko miejskie, ważne jest poszukiwanie alternatywnych rozwiązań, pozwalających ograniczyć owo negatywne oddziaływanie. W ostatnich latach bardzo interesującym i popularnym, jako efektywny system dostaw ostatniego kilometra, rozwiązaniem stały się paczkomaty. W artykule dokonano oceny użyteczności tego rozwiązania, bazując na przykładzie systemu firmy InPost.
