This paper examines the problem of reducing the production cycle for steel parts by developing and implementing the concept of complex workpieces for the simultaneous machining of several parts. This paper proposes representing the technological process of machining a complex workpiece as a directed graph, where vertices correspond to operations and edges correspond to transitions between them. This graph utilizes stochastic models such as Markovian random processes to account for uncertainty. The proposed approach is particularly relevant in highly responsive manufacturing environments, which require rapid adaptation to changing market demands and a customized approach to product manufacturing. Modeling the technological process allows for optimization of the sequence of operations, minimization of equipment changeover times, and ensuring consistent product quality.
