  • Methodology for Assessing the Robustness of Time Series Models Used in Inventory Management

    The article focuses on developing and testing a methodology for quantitatively assessing the robustness of time series models (SARIMA, Prophet, LSTM) used in inventory management under unstable external conditions. The proposed approach involves modeling input data distortion scenarios, including holiday demand surges, logistical disruptions, inflationary trends, and structural shifts. Robustness metrics—Robustness Index (RI) and Degradation Ratio (D)—are introduced to evaluate forecast degradation. Experiments on synthetic data show that high accuracy on clean data does not guarantee robustness: SARIMA is sensitive to inflationary trends, Prophet is robust to seasonality, and LSTM is vulnerable to structural shifts. The findings are applicable in logistics and retail for optimizing supply planning.

    Keywords: inventory management, time series, model robustness, demand forecasting, SARIMA, Prophet, LSTM, Robustness Index, Degradation Ratio, logistical disruptions, seasonal fluctuations

  • Management of fire and rescue units during rescue of people from public buildings by gas and smoke protection service units

    The aim of the study is to analyze modern models and algorithms for managing fire and rescue units during rescue of people in different types of public buildings. Research methods: general scientific methods (analysis and synthesis of information, comparison). The article provides a literature review of current methods and algorithms for managing fire and rescue units during rescue of people. Based on previous studies, three main approaches are identified: approaches based on technical superiority; approaches based on mathematical modeling; approaches based on taking into account the individual characteristics of the places where fire and rescue operations are carried out. The advantages and disadvantages of each approach are highlighted in terms of the effectiveness of their use in rescuing people in public buildings. When analyzing previous approaches, it is concluded that at the moment there is no methodology for substantiating the tactical capabilities of gas and smoke protection service units during fire and rescue operations depending on the technical characteristics of the premises and the number of people. The combination of mathematical modeling and consideration of individual characteristics of public buildings seems to be the most effective method of managing fire and rescue units. The study concludes that it is necessary to create an algorithm for the movement of gas and smoke protection service units that will take into account the characteristics of buildings, combustion products and the time of rescuing people. The scientific novelty of the study is due to the following elements: a systematization is proposed, and an assessment of the advantages and disadvantages of models and algorithms for managing fire and rescue services is performed; a scheme of measures for managing fire and rescue units is proposed, which takes into account the functional tasks of the fire and rescue garrison, guard service and work with the population. The scheme for managing fire and rescue units assumes both work with the entire fire and rescue garrison and with individual guard services of the fire protection service, with the population and the administration of public buildings. The proposed scheme complements the existing theoretical knowledge about the organization of the work of fire and rescue units and the management of their work when rescuing people in different types of public buildings.

  • Optimizing Communication Efficiency in Engineering Project Management

    Effective communication between project managers and engineering teams is critical for the success of construction projects. This article develops a hierarchical (Stackelberg) game-theoretic model, where the manager acts as the leader and engineering teams act as followers. The model quantifies how both the leader and followers balance the benefits and costs associated with increasing communication efforts. We propose a two‐level (Stackelberg) model of strategic interaction between a project manager (leader) and engineering teams (followers) in construction projects. An efficient numerical algorithm is implemented in MATLAB to compute optimal strategies and analyze different project scenarios. Scenario analysis demonstrates how changes in project parameters affect the balance of efforts and profits, thereby guiding managerial recommendations for improving communication and reducing project risks. By considering aspects like risk, time delay, cost overruns, and resistance to change, we provide supervisors and agents communication efficiency functions. Using scenario analysis and numerical optimization, we determine the most efficient communication tactics to match the hierarchical structure of building projects.

  • Models for Constructing Optimal Container Freight Plans for Complex Logistics Systems

    The article addresses the challenges and proposes mathematical models for optimizing container freight transportation within complex logistics systems, emphasizing the growing importance of digital technologies and artificial intelligence in logistics by 2025. It highlights key industry issues such as decentralized global supply chains, environmental risks, infrastructure deficiencies, safety concerns, and notably, the costly problem of transporting empty containers, which accounts for a significant portion of operational expenses worldwide and in Russia. The core contribution is a modified three-dimensional transport optimization model that incorporates container types, cargo volumes, and transportation costs, including the cost variations due to partially filled or empty containers. The model extends classical transportation problem formulations by introducing a potentials method that accounts for the contributions of suppliers, recipients, and container costs to determine an optimal transport plan minimizing total costs. Constraints ensure that supply and demand conditions, container capacities, and route feasibility are respected. The model uniquely integrates the degree of container filling into cost calculations using a coefficient to adjust transportation costs accordingly. This approach enables more accurate and cost-effective freight planning. Additionally, the article discusses the development of a simulation model and a client-server application to automate the search for optimal transport plans, facilitating practical implementation. The proposed framework can be expanded to include various container types, cargo characteristics, and transport modes, offering a comprehensive tool for improving logistics efficiency in container freight transportation.

  • Finding the Stackelberg equilibrium in the model of development of the subsidized region. The impact of coalition building

    The article examines the network model of district management within the subsidized region from the point of view of the upper level, taking into account the optimal response of the districts – the Stackelberg equilibrium is found. The results obtained are compared with the corresponding results in the creation of horizontal and integrated coalitions of districts and the region. The author examines the preference for creating coalitions for all participants in the system. It has been proven that cooperation is more profitable for weak and medium-sized districts, hierarchy is more profitable for a strong district, and independence is more profitable for the region as for the upper level. It is not profitable for the strong elements of the system to join a coalition, while it is more profitable for the weak elements to join a coalition.
