| Abstract [eng] |
The study examines the assembly process of special-purpose electrical panels, emphasizing the structural complexity of such production, relevant regulatory requirements, and the significant influence of manual operations on final product reliability. The role of electrical panels within distribution systems is explored by analyzing component interaction and technological characteristics that define strict adherence to the assembly sequence. The research systematizes the entire assembly cycle by examining wire preparation, component mounting, connection formation, and final testing, identifying the factors that most affect process stability and increase the likelihood of errors. Based on this analysis, a detailed assembly scheme is developed to clarify functional relationships between workstations, their interdependence, and critical points where the greatest variations in operation duration occur. This structural insight serves as a foundation for applying mathematical modeling to establish operational relationships, time distributions, and principles for evaluating alternative process solutions. Modeling enables the examination of various redesign scenarios, including improvements in workplace ergonomics, optimization of tool placement, the use of wire-processing technologies, and simplification of connection-forming operations. These scenarios are used to assess changes in operation consistency, movement frequency, workstation load, and overall process stability, while also considering how organizational decisions influence operator work rhythm, physical and cognitive workload, and the likelihood of human error. The model results show that well-chosen technological and organizational adjustments can enhance process uniformity, reduce unnecessary actions, improve assembly precision, and support clearer workplace logic, contributing directly to more efficient production. Alongside the technological aspects, the study also considers sustainability-related factors, including reduced waste generation, and a more ergonomic working environment. The resulting research methodology offers a structured approach for planning improvements in electrical panel production, evaluating the effects of process changes, and implementing well-grounded decisions aimed at increasing efficiency, quality, and long-term process stability. |
