Abstract

The paper investigates the problems of serial production of large-size modular structures using robotic conveyor lines. One of the objectives, the results of which are described in this paper, is to identify the most rational scheme of production flows, taking into account the convergence and divergence of flows. The evaluation of the concept of the technological complex of the created high-tech production is carried out by means of simulation modeling. At the first stage, a mathematical model of the existence of an in-line conveyor line is developed. Recommendations are given to ensure the compliance of the cycle duration with the calculated values during the transition from the simulation model to the conditions of real production. To ensure compliance of the cycle duration with the calculated values during the transition from the simulation model to the conditions of real production, a number of recommendations are formulated. The results of the research conducted in the paper allow to make decisions when designing the serial production of large-size modules with the area up to 100 and more square meters, as the conducted calculations allow to determine the number of necessary workplaces in the future production and comprehensively assess their load. The developed simulation model allows to determine the duration of the production cycle from the moment of launching the product into production to the output of finished products.
