DPS - Data Processing Service platform

Equipped with a modern web interface, the DPS allows for building the sequence of process steps from individual ‘unit opera­tions’ to be placed on the flowsheet and connected by simple mouse clicks.

The calcu­lation flow can be triggered based on user-defined points of time or time intervals, or event-based by ‘watch-dog’ criteria applied on one or several online signals.   Various types of data sources can be linked to the process with modules based on published API infor­mation or standard commu­ni­cation protocols.

Config­urable modules for range and steady-state checking as well as logical operators make sure that only valid inputs and reasonable replacement values are processed, or that the calcu­lation is skipped if essential inputs are faulty or missing.

The actual calcu­lation process begins with the mapping of the signals to the model parameters, which may also include side calcu­la­tions defined in C# or Python or variable type trans­for­ma­tions.  These parameters are then fed into a Calcu­lation Job module that manages the execution of the simulation model.

Once the results of a job are returned to the processing scheme, the post-processing steps may involve further logical checks and customized calcu­la­tions before they are mapped to output signals and written to one or several target data repos­i­tories.
