The model of the production process of the party of the subjects of labour.

The article discusses the construction of the model of streaming production line with the constraints on the technological trajectory of subjects of labour. The work shows the influence of the subject of labour movement trajectory, which is related to the limited maximum capacity of the operating storage. It analyses constraint that is associated with the serial order of subjects of labour processing. The equation for the trajectory of the regulatory process is built, taking into account the constraints on the trajectory of the subjects of labour, which can be used for closing the balance equations of PDE-models of streaming production lines.
