Application possibilities of logistics simulation and AI in the case of intermodal terminals

2024-12-03T10:38:40+01:00

Abstract: The paper addresses the fundamental operations and services of intermodal logistics terminals from the ground up. The information collection was primarily based on site visits to several companies, one of which was East-West Intermodal Logistics Service Ltd., and the other was ZÁHONY-PORT Ltd. (Záhony-Logistics and Load Handling Servicing Company). The process continued with data collection, where local leaders and managers provided information through PowerPoint documents and site tours. The entire information gathering process started with the understanding of the main details of the companies, followed by the site visits, and finally, the acquisition of the requested information. The next step was the processing of the collected information, of which the article only describes the analysed results. The application possibilities of AI are closely related to digitization and data collection. Without data, AI cannot be trained for the given task. To increase the available information, we can also use simulation methods (for generating so-called synthetic data), allowing us to introduce artificial intelligence in a relatively new field in a short time.

The always changing data problem of using AI in manufacturing - Using synthetic data from the digital twin to feed AI models

2024-09-30T09:52:31+02:00

Production is becoming increasingly flexible, which also requires the flexibility of the support system for the production. And the key here is the speed of decisions, in which the support of modern artificial intelligence systems can be crucial. Flexible production is based on a well-planned control of production, which increasingly uses some artificial intelligence component. Artificial intelligence can already be useful in the early stages of planning the production line, and of course it can also control the daily operation of the production line after the installation of the production place or line. The biggest problem is supplying the neural network that controls the artificial intelligence with training data. The production lines typically change every 2-4 months, new products appear, the layout changes, and the main process data also changes due to the development of the processes. This results in the training data becoming outdated or obsolete very quickly and thus cannot be used to train models anymore. High-quality learning data can be produced by digital twin models of production lines. Such synthetic data has several advantages over data collected from production. In this article, we investigate how useful this synthetic data is during the life cycle of the production line.

Design methodology for the control logic of flexible production systems and related logistics

2024-03-01T10:54:47+01:00

The ever-shorter product life cycle entails a shortening of the life cycle of the production site and production systems as well. One of the biggest advantages of flexible production systems is that new products can be introduced to them continuously, so that their life cycle can be significantly extended. Flexible manufacturing systems, on the other hand, also require flexible control, the logic of which must be defined already in the design phase. The main elements of the design methodology of the production and logistics layout that make up the research are the information relationship chart and the related decision tables, which are suitable for speeding up the design and later for facilitating the creation of a digital twin and control logic programming.

Modelling and optimizing material flows in electrical energy distribution – first model

2023-12-11T13:56:51+01:00

The paper focuses on modelling and optimizing the distribution of material flows in a first version. Furthermore, the focus is on electrical energy flows, considering different energy sources and types of consumers. The most commonly used energy sources are nuclear, thermal, renewable and geothermal. The main categories of consumers include industry, residential, commercial and, increasingly, electric transportation. A first model is proposed which uses matrices for the various time constraints and uses graph theory to represent the flow of energy between sources and consumers. Variables and constraints are established to ensure that the flow remains within maximum capacities and meets minimum demands. In addition, a first version of mathematical model is proposed to minimize total energy supply costs.
