Method for integrated data handling for engineering and operation of a plant having a plurality of software applications with different functionalities, wherein the plurality of software applications are interconnected via a network, a common data model including data shared between at least two of the plurality of software applications is provided, the common data model is managed by a configuration data service, data specific to a single application is managed by an application specific configuration data service that is assigned to a number of applications such that flexible, consistent, performance-optimized and efficient management of the various heterogeneous systems in the plant is achieved.

Method for integrated data handling for engineering and operating a plant

In order to give architects engineering the software of software architectures with its various software artifacts of complex cyber-physical systems of different technical domains a powerful way to identify and control architecture erosion in codebases of the complex cyber-physical systems, a method or tool is provided that may (i) diagnose and categorize software artifacts dependencies in the software architectures of complex cyber-physical systems triggered by revisions or commits, (ii) relate changes in the diagnosed and categorized dependencies with change events on the software artifacts, e.g., those caused by at least one of enhancing the complex cyber-physical system with new features as required by market demands and fixing defects found in operation and/or raised during maintenance of the complex cyber-physical system, and (iii) represent the diagnosed and categorized dependencies and the related changes in the diagnosed and categorized dependencies.

Method and tool for engineering software architectures with its various software artifacts of complex cyber-physical systems of different technical domains

A method for controlling a grid of plants, wherein the method includes interconnecting distributed control systems via a network, providing a hierarchical tree structure having at least two levels (LN) for the network, assigning each distributed control system to a node of the tree structure, receiving a data request at a parent node control system, determining whether the data request is resolvable by the parent node control system, where a reply to the data request is sent if the data request can be resolved by the parent node, and where the data request is forwarded to at least one of the child nodes of the parent node if the data request is unresolvable by the parent node such that monitoring and controlling of the entire grid with respect to the inclusion of further units and the modification of already existing units is achieved in a flexible manner.

Method for controlling a grid of plants

A management apparatus and a method for managing a software development and maintenance system are provided. In order to improve the quality and to minimize errors in a code base, an analysis of individual parts of the code base and related functional and/or architectural concerns is performed.

Apparatus and method for managing a software development and maintenance system

A method for determining an extent of code changes upon implementation of a software modification has the steps of: registering the number of software code components and the respective number of lines of code of each software component of a software code before the implementation of the software modification, implementing the software modification by changing the software code, determining the number of software code components that have changed due to the implementation of the software modification, determining the number of lines of code of each software component that have changed due to the implementation of the software modification, and determining an invasiveness value on the basis of the determined number of software code components that have changed and determined number of lines of code that have changed, the invasiveness value being indicative of the extent of software code changes upon implementation of the software modification.

Software quality evaluating system and methods for determining an extent of software code changes

An apparatus and a method for identifying relationships between data elements stored in a storage system are provided. A common check-in procedure of related data elements is analyzed, and an additional database is provided for storing information of data elements that have been checked-in together. Based on an analysis of information stored in the additional database, an indication may be automatically generated and provided to a user in order to give a hint for related data elements.

Management apparatus and method for managing data elements

A method for analyzing changes in a software code may have the steps of: inputting a plurality of different versions of a plurality of software artifacts to a change analysis device, deriving design constructs of the software code of the software artifacts by using an abstract syntax tree analysis, with the software code differences between the different versions of each of the software artifacts, classifying the derived design constructs of each of the software artifacts according to the compared software code differences, and outputting a visualization of the design constructs of each of the software artifacts, which visualization is structured according to the classification of the design constructs.
