Combining models of synchronizing physical and digital processes in small spacecraft manufacturing

A combined model of synchronization of digital and physical processes for the production of small CubeSattype spacecraft taking into account the degree of automation and the specifics of each stage of production in order to achieve the least possible desynchronization, is developed. The methodological basis is the methods of synchronization of digital and physical production processes, which ensure that the dynamics of controlled operations are taken into account and predicted. Using Python, the misalignment is calculated using several synchronization models for each stage of production, as well as for the total average error of the entire production. The mathematical model of combined synchronization is adjusted by introducing weighting factors that take into account the degree of automation of the CubeSat manufacturing process, considering the advantages of each individual model. The proposed model can be used in processes of various levels of automation: from low to close to the serial production level of small spacecrafts.
