Abstract

This study develops a Discrete Event Simulation model to analyze a municipal meat production system spanning six production stages from crop cultivation to distribution. The model was constructed in AnyLogic 8.9.6 representing crop production, feed milling, livestock fattening, slaughtering, meat processing, and distribution. Baseline simulation over 365 days achieved throughput of 40 entities per year with average cycle time of 274.5 days. Resource utilization analysis identified feed mills at 75% and animal farms at 74% as primary bottlenecks, while downstream resources showed severe underutilization at 1-2%. Three scenarios tested increased demand, resource investment, and supply disruption. The increased demand scenario achieved zero throughput improvement despite 50% higher input. Resource investment with 60% more feed mills and 50% more animal farms achieved 50% throughput improvement. Supply disruption-maintained baseline throughput through inventory buffering. Results provide quantitative support for municipal capacity planning decisions.

KEYWORDS: discrete event simulation, municipal production systems, bottleneck analysis, resource optimization, capacity planning, supply chain management, food security.

Abstract

Duality for nonplanar networks is a fundamental problem that remains unresolved. Kuratowski [5] showed that there is no graph or network dual to a nonplanar network. He demonstrated that there are only two such graphs that cannot be represented on a plane without self-intersections: the bipartite graph on six vertices with nine edges and the complete graph on five vertices with ten edges. The structure of networks dual to nonplanar networks cannot be represented, but it turns out that they correspond to transformation matrices that can be used to calculate responses to influences. Thus, there are no networks, but flows in them do exist, although they have strange properties. Since the dual network can (must) be located in a space dual to the observed space where the given network resides, nonplanar networks can be the contact point between these spaces.
A dual network corresponds to a path transformation matrix that is orthogonal to the transformation matrix of the original network. The strange thing about nonplanarity is that, by connecting individual branches (nine or ten) into increasingly complex networks, a dual network is always obtained. This can be constructed on a plane as a dual graph, or using a transformation matrix orthogonal to the given network. When connecting branches and reaching a nonplanar network, the dual network “disappears,” but with further connections, it reappears.
One might expect that since there is no dual network for a nonplanar network, there would also be no transformation matrix for its paths when going from the simplest network of individual branches to a connected network. Or perhaps this matrix has some singularities. It turns out that the transformation matrix of a nonplanar network has an inverse matrix, meaning there are no singularities. Transposing this inverse matrix yields an orthogonal matrix, which should correspond to the transformation matrix of the dual network.
Theoretically, it is impossible to construct a network dual to a nonplanar network using this matrix. However, when attempting to construct it, it turns out that the “dual” network of a bipartite graph on six vertices is similar to the complete graph on five vertices, although not completely – one branch is missing. When attempting to construct a “dual” network of a complete graph on five vertices, the resulting network is similar to the bipartite graph on six vertices, although not completely – one branch appears to be superfluous.
Thus, the transformation matrix of a nonplanar network exists, indicating that a corresponding network must also exist. Using the transformation matrix of a network dual to a nonplanar network, one can calculate the network’s solution matrix, represented by the metric tensor of its structure, although its form cannot be explicitly represented. This article discusses the results of research into the structure and processes in networks dual to nonplanar networks that cannot be represented. The practical interest of this problem lies in the fact that a bipartite graph on six vertices can be interpreted as three product-producing industries connected by supplies, i.e., this graph is at the core of economics and its model. The money supply network is dual to the product production network. A nonplanar graph in the product flow network can generate inconsistencies and contradictions in the money supply network.

KEYWORDS: nonplanar graph, dual network, transformation matrix, duality invariant, energy flow conservation law.

Abstract

The paper presents the development of an adaptive traffic control system (ATCS) for a single intersection, aimed at increasing its throughput. The proposed solution is a digital prototype of an intelligent ATCS implemented in Python and equipped with a graphical user interface (GUI) for monitoring and adjustment. A computer vision module based on the YOLOv4-Tiny neural network was integrated for collecting data on vehicles and pedestrians. The system implements a control algorithm that adjusts traffic light phase timings in real time according to three designed scenarios: night mode, peak hours, and medium load. For comparative efficiency analysis, a digital twin (DT) simulation model was developed in AnyLogic. The simulation included throughput assessment under different scenarios. The results showed that the introduction of adaptive control algorithms reduces the average intersection travel time by 14–32% compared to traditional static algorithms.

KEYWORDS: digital twin, traffic control system, traffic light, adaptive control, intersection, simulation modeling, computer vision.

Abstract

This study presents the concept of a digital twin for modeling material flows in the economy of a municipality. A simplified agent-based model that reproduces the movement of goods and services between key participants in the economic system (households, enterprises of various industries, and local governments) has been developed. The research is based on a scenario analysis that includes three areas: fiscal policy, crisis situations, and infrastructure projects. The simulation results revealed a nonlinear relationship between the tax burden and budget revenues and also demonstrated the effect of sectoral asymmetry (different industry responses to identical management impacts). The scientific novelty of the work lies in the development of a methodology for integrating agent-based modeling with the concept of digital twins for municipal management tasks. The practical significance is confirmed by the conclusions about the critical 6-month period for the implementation of anti-crisis measures and the identified budget payback of logistics projects (3.2 years). The model allows predicting the consequences of management decisions, taking into account the spatial distribution of economic activity, intersectoral relationships, and adaptive behavior of economic agents. The obtained results can be used to optimize municipal economic policy and develop socio-economic development programs.

KEYWORDS: digital twin, agent-based modeling, municipal economy, NetLogo, scenario analysis, material flows.

Abstract

Countries are striving to develop critical technologies that are essential for the structural transformation of their economies and enhancing their international competitiveness. The pandemic and current geopolitical challenges have heightened the risks of technological interdependence among countries. The advantages and disadvantages of technological sovereignty can be explained through interdisciplinary research, but achieving it requires a productive and balanced approach. Technological sovereignty is a concept that goes beyond data and technology regulation and entails funding innovation and stimulating innovative entrepreneurship. At the same time, we note significant differences in the approaches of key countries to managing digital sovereignty.
