Definitions

  • the invention relates to a method and device for distributing software components of one or more applications to infrastructure components of an industrial infrastructure that are suitable for their execution, as well as an associated computer program (product).
  • An industrial infrastructure can be a modern automation system. It is characterized by centralized and hierarchical control architectures, such as B. the automation pyramid according to the ISA-95 and IEC 62264 standards. According to these standards, the actual conventional architecture of the automation pyramid represents a clear separation of systems and functionalities in five architectural levels that have their own specific automation purpose and only exchange information with the adjacent architectural levels.
  • the lowest architecture level represents the manufacturing and production process, which is controlled by means of input and output signals I / O of a field environment by so-called PLC machines (PLC in English: PLC: Programmable Logic Controller) in a control environment.
  • PLC machines PLC in English: PLC: Programmable Logic Controller
  • This architecture level is usually developed as a process control and / or communication network environment and is often abbreviated to the term SCADA (Supervisory Control and Data Acquisition).
  • An operations management environment or level forms the next higher architecture level and is often abbreviated to the term MES (Manufacturing Execution System).
  • MES Manufacturing Execution System
  • a corporate environment or level forms the highest level of architecture and is often abbreviated to ERP (Enterprise Resource Planning).
  • ERP Enterprise Resource Planning
  • a hierarchical structure is very robust and emphasizes good predictability and global system optimization.
  • this structure is effective for small systems that are implemented in very stable and structured environments in which the pyramid according to ISA-95 can be used for easy development and maintenance.
  • This reliability between the architectural levels leads to insufficient adaptability and Flexibility with production changes.
  • a single point of failure can drastically reduce system performance.
  • Information also becomes inconsistent and out of date once a communication delay occurs that affects partial and global decision-making.
  • Various types of hardware and software are used here. This means that communication between these components is also inhomogeneous.
  • Maintainability, expandability and updateability also suffer from these inhomogeneities.
  • This environment there is a desire to create a seamless transition between the architecture levels described above. It makes sense to use a modular system as an industrial infrastructure. Such a modular system usually only works if all infrastructure components and interfaces of the applications work properly and if certain boundary conditions are met.
  • the infrastructure components can include the computing nodes and network nodes.
  • the infrastructure components can be physical and / or virtual components.
  • Computing nodes are parts of computing units; they can either be pure hardware nodes or virtual machines.
  • Computing nodes of other domains, such as the cloud, the data center or the edge, are modeled in the same way, ie the properties of the domains are expressed by the properties of the model components.
  • the interfaces each have certain characteristics (eg computational complexity, memory requirements, data rate, call frequency).
  • additional restrictions that must be met so that the application can be viewed as fully functional (e.g. end-to-end latency, response times, availability of the application or parts of the application, data protection restrictions for infrastructure components or interfaces) .
  • These features and restrictions describe interface-specific properties.
  • the infrastructure components of an application usually run on different computing nodes, eg Cj, possibly in different domains or different production cells.
  • the computing nodes can be connected to one another via a single or multiple network paths.
  • the different computing nodes can be heterogeneous, ie they have different ability-specific properties, eg computing capacity, main storage capacity, storage capacity, CPU architecture.
  • the connections and the network nodes Ni can also have different properties. Transmission-specific properties of the connections are, for example, bandwidth and latency, and resource-specific properties of the network nodes are, for example, response time, failure safety and availability.
  • a state-of-the-art technology for implementing applications that can be divided into modular software components is container technology (such as Docker).
  • Software components can be packed in containers that can run on one or more container clusters.
  • the latest technologies for managing multiple containers on a cluster are container orchestration technologies such as Kubernetes.
  • Kubernetes has a scheduler that assigns pods (a collection of containers) to a set of nodes within a cluster.
  • a node is a computer system, physical or virtual, that is set up to operate containers under the control of Kubernetes.
  • a cluster is an overall system made up of nodes.
  • Kubernetes summarizes container images (memory image of a container), their configuration and the number of required instances in deployments.
  • Kubernetes automatically monitors the parameters of a deployment. The tool ensures that the required number of containers is running at all times.
  • Kubernetes distributes changes to the software or the configuration with a rollout.
  • Kubernetes was not designed for such a hierarchical architecture as is used in the industrial environment. When distributing the pods, no skill-specific, transmission-specific or resource-specific properties within the infrastructure mentioned are taken into account.
  • a scheduler for mapping industrial applications to a specific infrastructure has already been proposed in EP 19152467.7.
  • MILP mixed integer optimization
  • MILP is concerned with optimizing linear objective functions over a set constrained by linear equations and inequalities. It is the basis of the solution methods of (mixed) integer linear optimization.
  • a so-called solver is a collective term for special mathematical computer programs that can solve mathematical problems numerically.
  • standard solvers such as CPLEX, Scip, Gurobi, Xpress can be used for IP programs (integer optimization models).
  • the object is achieved by the features specified in the independent claims.
  • Advantageous developments of the invention are presented in the dependent claims.
