20220342398 · 2022-10-27 ·

The method for self-learning manufacturing scheduling for a flexible manufacturing system (FMS) with processing entities that are interconnected through handling entities is disclosed. The manufacturing scheduling is learned by a reinforcement learning system on a model of the flexible manufacturing system. The model represents at least the behavior and the decision making of the flexible manufacturing system, and the model is transformed in a state matrix to simulate the state of the flexible manufacturing system. A self-learning system for online scheduling and resource allocation is also provided. The system is trained in a simulation and learns the best decision from a defined set of actions for many every situation within an FMS. A decision may be made in near real-time during a production process and the system finds the optimal way through the FMS for every product using different optimization goals.

A system for assigning a workload to compute resources includes an interface and a processor. The interface is configured to receive a workload. The processor is configured to break the workload into a set of subproblems; and for a subproblem of the set of subproblems: determine whether the subproblem benefits from intersheet parallelism; determine whether the subproblem benefits from intrasheet parallelism; determine whether the subproblem benefits from directed acyclic graph (DAG) partitioning; and assign the subproblem, wherein assigning the subproblem utilizes optimization when appropriate based at least in part on benefits from the intersheet parallelism, the intrasheet parallelism, and the DAG partitioning.

Graph theory and network analytics and diagnostics for process optimization in manufacturing
10248110 · 2019-04-02 · ·

A system, method, and computer-readable medium are disclosed for analysis and characterization of manufacturing information such as process trees or genealogies using graph theory. More specifically, using graph theory to analyze manufacturing information of a manufacturing operation allows for deep analysis of relationships between batches or units in a process tree and their closeness or distance, to identify clusters associated with specific quality characteristics or problems, to identify common antecedents of specifically labeled batches (e.g., problem batches), and/or to detect overall desirable or undesirable characteristics of the process tree (e.g., centrality, etc.).

GRAPH-DRIVEN PRODUCTION PROCESS MONITORING

A system and method are disclosed for production process monitoring using graph learning. A production ontology is generated based on data received from an engineering design process, the ontology including selection of production machines, definition of a product, and workflow design. A production graph is instantiated based on the production ontology. Production process data is read from control systems of the production environment and the production graph is populated with the production process data to generate a time series of production graphs. Prediction information is received from historical production graphs of related production processes. Offline runtime analytics are performed on the production graph to yield analytics results including a plurality of predictors. The predictors include knowledge from the received prediction information leveraged with a weight sharing initialization.
