Dear readers! You are holding the combined issue of the “LOGISTICS” journal, in which we have collected materials for July and August 2026. It brings together practice and theory, applied solutions and bold methodological explorations.
Dear readers! We are pleased to present you with the sixth issue of the journal for 2026, in which the theory and practice of logistics are explored in a variety of relevant areas. This issue is truly multifaceted, combining reflections on the essence of logistics processes with applied calculations and industry-specific cases.
Annotation. This paper examines the impact of changes in some parameters of models describing demand on the solution of the problem. It is assumed that the distribution functions of random variables describing demand are unknown, but their mathematical expectations are known. The generalized problem is posed as a discrete programming problem with nonlinear separable functions. For an approximate solution of the problem, its continuous relaxation is performed. The solution method involves linearizing the continuous relaxation and using separable programming and branches and boundaries schemes.
Key words. Iinfrastructure, mathematical programming, demand, stability.
