A wide range of software and hardware components are present in today’s production systems and plants using a variety of interfaces and data formats for information exchange on diff erent levels of the system. To increase the traceability, the lifecycle management and providing a single point of source of component-specifi c data, the Digital Twin technology is proposed, linking diff erent data sets tailored to the requirements of diff erent kind of users (e.g., machines, technicians, logistics, manufacturing execution systems). The data exchange between entities in the manufacturing network relies on machine-readable, fl exible and self-describing data formats. When implementing or integrating diff erent components into complex systems, the interoperability challenge is a major concern to address by the system designers and becomes a central task for the creation and integration of Digital Twin technology. In this paper, we evaluate diff erent formats that are used in real environments and create a requirements framework for an ideal format for exchanging fl exible and self-describing data in context of optical components manufacturing process and their special requirements.

From the findings that UTH increase begins with a build-up of positive divergence even before the evaporation of cloud hydrometeors takes place and that UTH increase ends with an appearance of negative divergence values even before the evaporation ends, it is strongly suggested that moistening of the UT is more closely tied with water vapor transport from the convection center to surrounding areas than with the evaporation of cloud hydrometeors. Considering that vapor concentrations are nearly an order of magnitude larger than those of cloud ice, the higher degree of correlation shown between UTH tendency and divergence supports the notion that advection of moist air from the convection center is likely to be the main factor responsible for moistening of the UT.
