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.

Autonomic manufacturing operator authorization adjustment

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.

Activity based real-time production instruction adaptation

An apparatus and method for correcting up to two errors in a sequence of data elements read front a data track of a disc drive and detecting the occurrence of more than two errors. A syndrome generator determines a syndrome, having five components, from the data elements and the components are transmitted to a syndrome weight generator that provides an indication of a syndrome having a zero Hamming weight and to a detector that generates an indication of whether a selected component is zero. These indications are transmitted to a decoder. A determinant generator generates determinants that are combinations of selected components and a determinant weight generator determines a code indicating the Hamming weight of selected determinants. Such code is transmitted to the decoder. Discriminator and trace detectors generate additional signals determined from the components and determinants that are transmitted to the decoder. The decoder determines the number of read errors from the received signals and transmits single and two error indicator signals to correction circuits that generate error values that are added to erroneous data elements as the elements issue from a shift register through which they are passed during reading.
