Analysis of the State of the Issue
The platform for a single information space (USIS + PLSI) Digital Twin is an information technology based on system information models of processes and digital and material production systems.
System-information models of the information process allow solving production problems based on knowledge of the source information parameters, which are informationally related to the receiver information parameters.
The presence of parameter uncertainty in system information models allows, based on the information stability coefficient, to manage the quality of the system and its operating efficiency in space and time based on the Digital Twin platform of a single information space (USIS + PLSI).

Conclusion (1/2)
A digital twin of a production process is a set of interconnected digital twins of technological operations (elementary technological process) at the stages of the product life cycle. They are intended to help improve the accuracy and quality of product manufacturing.
System information models of cutting processes underlie the software of the platform of a single information space (USIS + PLSI) of the digital twin of technological operations. The platform for a single information space (USIS + PLSI) Digital Twin is an information technology based on system information models of processes and systems of digital and material production.
A feature of the software (USIS + PLSI) Digital Twin technological operations is the use of system information models based on the concept of the type of system information of parameters of machining processes.

Conclusion (2/2)
The nominal value of a parameter has a certain measure of uncertainty in system information when its value is within the range of expanded uncertainty. This characterization of the system information of the parameters of virtual and material production allows you to control the quality of the manufactured product with a digital twin based on the structure of the parameter model.
The information stability coefficient characterizes the ratio of the sensitivity threshold value to the expanded uncertainty of the parameter. It determines the stability of information connections of parameters in a technological system. This characteristic of the system information model of a technological process parameter is one of the indicators of the quality and efficiency of mechanical processing of both real production and the digital twin.
