Návrh a implementace systému pro automatizaci procesu zpracování celní deklarace pro vývoz zboží z Evropské unie

This master’s thesis deals with the design and implementation of a software system prototype intended to automate the processing of export customs declarations within the European Union. The current state in the analysed enterprise exhibits a high degree of manual data transcription, an increased risk of error, and the absence of a centralized data repository. The primary objective of this work is to eliminate these inefficiencies through an automated workflow that ensures the conversion of unstructured documents into a structured format and assisted item processing. The proposed solution utilizes a modern technological architecture consisting of the n8n automation platform for process orchestration, a PostgreSQL relational database for data management, and a locally operated language model for description translation and automated description matching with historical records. The system also includes a user interface for final data verification and editing before export to the subsequent Helios CLA system. The prototype's functionality was verified through pilot testing on real-world data. The results demonstrated a reduction in the time required to process a single declaration by approximately 70% and a 60% reduction in the item error rate. Thus, this thesis presents a practically applicable solution that significantly increases the efficiency of the customs process and establishes a technological foundation for further digital transformation of the enterprise.
