摘要:
A system and method can identify manufactured parts. A user can select a particular manufactured part, which can be out-of-specification. The system can retrieve test data for the selected part and for other manufactured parts. The system can normalize the retrieved test data against historical means and historical standard deviations to form normalized test data. The system can correlate the normalized test data for the selected part against normalized test data for each of the other manufactured parts to form correlation values. The system can display the correlation values with identifiers corresponding to the manufactured parts. Each correlation value can represent a degree of similarity between the selected part and a respective manufactured part. The manufactured parts with the highest correlation values can have the same failure mechanism as the selected part, which can help diagnose why the selected part can be out-of-specification.

User interfaces for displaying visual representations of relationships between cells in a grid. In one example embodiment, a user interface includes a grid including rows and columns, a viewport that displays only a portion of the grid, and a plurality of cells each having a specific position in one of the rows and one of the columns of the grid. A first one of the cells is related to a second one of the cells that is positioned in a different one of the rows and a different one of the columns of the grid from the first cell such that the first cell and the second cell are not capable of being displayed in the viewport at the same time. The viewport is configured to display, upon selection of the first cell displayed in the viewport, a completely visible visual representation in the viewport of the relationship between the first cell and the second cell.

A plurality of tool identifiers, a plurality of information types, and a plurality of report types are displayed in a first user interface of a tool health reporting system. A user selection of a distinct report type from the plurality of report types, a distinct information type from the plurality of information types, and a distinct tool identifier from the plurality of tool identifiers are received. A report is displayed in a second user interface of the tool health reporting system, the report including data associated with the distinct information type, the distinct report type and the distinct tool identifier, wherein the report correlates equipment based measurement data to product level measurement data.
摘要:
Systems and methods are provided that allow a user to monitor, diagnose, and configure a process. A user interface may be presented that displays data received from process monitors, sensors, and multivariate models. The user interface may be interactive, allowing a user to select which composite and multivariate models are displayed. The user interface and multivariate model may be constructed and updated in real time. The user interface may present various data and interfaces, such as a representation of a composite variable in a multivariate model, a representation of the contribution of process variables to the composite variable, and a representation of a subset of the process variables. The user may select a point of the composite variable for analysis, and the interface may indicate the contribution and values of process variables at the selected point. The interface may be transmitted to a remote user.

In a method of controlling a manufacturing process, a Mahalanobis space of plural manufacturing control parameters is generated on the basis of first sampled data. Then, a Mahalanobis distance from the Mahalanobis space and second sampled data is calculated. A manufacturing process is determined to be under a malfunction operating condition by comparing the Mahalanobis distance and a threshold value.

In order to solve the conventional problem in which the occurrence of abnormal behaviors in a manufacturing apparatus cannot be properly determine in view of the variations in measured data caused by adjustment made to the manufacturing apparatuses, the combine-information processing apparatus comprises: an inspectional equation storage unit 103 for storing an inspectional equation calculating one or more principal component scores, the inspectional equation being obtained by performing a principal component analysis on measured data on a plurality of measuring objects in terms of two or more correlated measurement items, and the measuring objects being processed by the manufacturing apparatus whose adjustable conditions are changed while the manufacturing apparatus is in a normal state; an inspected measured-data acceptance unit 104 for accepting inspected measured data on the measuring objects processed by the manufacturing apparatus in terms of the measurement items corresponding to each term contained in the inspectional equation; a principal-component-score calculation unit 105 for calculating principal component scores using the inspected measured data with the inspectional equation; an inspecting unit 106 for inspecting the manufacturing apparatus using the calculated principal component scores; and an output unit 107 for outputting the inspecting results.
摘要:
The present invention is a method for detecting an abnormal event for process units of an ethylene processing system. The method compares the operation of the process units to a model developed by principal components analysis of normal operation for these units. If the difference between the operation of a process unit and the normal operation indicates an abnormal condition, then the cause of the abnormal condition is determined and corrected.
