SUSTAINABLE MODEL OF MANAGEMENT OF THE TRANSPORT COMPONENT OF A CUSTOMS AND LICENSE WAREHOUSE

Effective management of the transport component of a bonded warehouse is an important factor in ensuring the continuity of logistics processes and optimizing costs in international trade. In the context of globalization and dynamic development of world markets, there is a growing need for sustainable logistics models that are able to adapt to changes in the regulatory environment, digitalization and challenges associated with geopolitical instability. The loss of part of logistics capacity due to military actions in Ukraine emphasizes the need to develop effective management solutions to minimize risks, increase the level of process automation and improve interaction between customs authorities and business. The article aims to solve a scientific problem of theoretical and methodological orientation, the essence of which is to develop a sustainable model of transport component management using the example of building a bonded warehouse. Based on the generalization of existing scientific achievements, the article clarifies the concept of a “sustainable model”. The goal of a sustainable model is outlined, the essence of which is to minimize the total costs of transport provision while meeting the requirements of throughput, delivery times and optimal use of resources. An algorithm for developing and testing a sustainable transport component management model has been developed, which involves collecting input data, entering the necessary parameters, checking constraints, allocating resources, assessing efficiency, deriving the optimal route, total costs, and environmental indicators. Nine variables of a sustainable model for managing the transport component of a bonded warehouse have been proposed. Binary variables (vehicle k on the route between points i and j) and weighting factors (α, β) have been determined. The introduction of five model constraints (vehicle throughput, demand provision at delivery points, time constraints, compliance with environmental standards, and logistics cyclicity) has been justified and the feasibility of its verification (testing) based on linear programming using the simplex method (numerical modeling). A sustainable model for managing the transport component of a bonded warehouse has been tested in Python, which allowed us to establish the dimension of the objective function as 6 (three delivery points for two vehicles), and the optimal number of constraints, which is 9. The presented scientific developments contribute to increasing the efficiency of logistics operations and the competitiveness of Ukrainian business in the international arena.
