Assessment of zones of influence on the efficiency of city transport logistics
No full textThe modern development of cities is accompanied by a constant increase in the volume of traffic flows, which necessitates the improvement of transport logistics. An essential aspect of enhancing the quality of life, ensuring mobility, and reducing environmental pollution is the economic stability and efficiency of the city's transport system. Urban transport logistics is a multi-component system that includes planning, coordination, and management of all types of transport movement, optimization of infrastructure, and integration of innovative technologies.
The study of modern approaches to assessing the efficiency of transport systems, considering their role in ensuring population mobility, economic development, and environmental sustainability, provides an opportunity to develop and implement methodological foundations for evaluating the efficiency of this system. This is particularly relevant in the context of rapid urbanization and global trends toward sustainable urban development.
It has been established that the efficiency of urban transport logistics is influenced by specific factors, including the accessibility of infrastructure, the reliability of transport services, the rational use of transport resources, the system's ability to adapt to changes in the socio-economic environment, and the degree of integration of modern technologies.
The implementation of innovative approaches in urban transport logistics will create conditions for improving the productivity of the transport network

The task addressed is the need to compile recommendations for determining the required number of personnel and the duration of rendering transport services depending on the type of cargo received for service. A simulation model of the work of a transport enterprise when organizing international road transportation has been built and implemented in the GPSS World simulation modeling automation package. The model involves determining the duration of transport service and planning the personnel support for a transport enterprise according to the functional division of labor. When building the model, the duration of the types of work provided by specialists of the transport enterprise when transporting general, dangerous, and oversized cargo was taken into account. In addition, the model takes into account the probability of errors and delays at each stage of service. The average duration of the delay in the event of errors is also determined, which could make it possible to set additional time for engaging a separate specialist to eliminate them. The application of the devised model in practice would allow owners of transport enterprises to organize business processes depending on the available type of rolling stock. It could also make it possible to determine the optimal number of specialists of various profiles required for organizing transport services for the customer. At the same time, the duration of transport services for the delivery of various types of cargo will be reduced by 8–14% while the number of specialists of the transport enterprise – by 10–15%; in turn, the throughput will increase by 7–16%.UKR: Об’єктом дослідження є процес організації та планування роботи транспортного підприємства при перевезенні генеральних, небезпечних та негабаритних вантажів автомобільним транспортом у міжнародному сполученні.

Building a model of leadership development for times of change. The author wants
to analyze what happens with potential leaders during times of crises, how crises affect
positively or negatively their leadership skills, and which opportunities and threats could be
used in order to protect and encourage their leadership development. The objective is to
provide the theoretical foundation on how leadership development works in times of change
and crisis. As an essential part of this objective, the author wants to study particularly the
relevance of role models and values during times of change for the development and training
of leadership skills. The main hypothesis is that role models and system of values are two
factors which could hinder or encourage significantly the possibilities of leadership
development during times of change. The author uses extensive theoretical research, surveys,
case studies, and interviews with experts.
