  • Patent number: 9489651
    Abstract: Operator authorizations are autonomically adjusted in many ways to automatically account for many different variables. Operator authorization may be adjusted according to an operator's past activity record so previous experience is not lost when the operator is rehired. Operator authorization may be adjusted according to the operator's quality and performance. Operator authorization may also be adjusted by recognizing similar operations to those the operator is authorized to perform, and authorizing the operator to perform one or more similar operations. Operator authorization may also be adjusted to a lesser level or may be revoked for an operation based on the passage of time. A manufacturing system may efficiently track operators taking into account different activity periods, the passage of time, the operator's performance, and similar operations to autonomically adjust the authorization of the operators as needed.

  • Patent number: 7920935
    Abstract: A manufacturing process for automatically delivering an appropriate level of instructions to a manufacturing operator on demand based on the manufacturing operator's level of activity and performance, the particular characteristics of the product being manufactured, and the particular production environment. Responsive to receiving an order for a product, the manufacturing process identifies an authorization level assigned to an operator performing a particular manufacturing activity on a part in the product and assigns a default level of instructions to the operator based on the authorization level. The process collects and models characteristics about the manufacturing environment, performance history of the operator, and knowledge decay of the operator to determine an appropriate level of instructions to provide to the operator performing a particular manufacturing activity. The manufacturing instructions associated with the appropriate level of instructions are then provided to the operator.
