Abstract

A computer implemented method, system and program product for monitoring operating procedures in a production environment. Data can be compiled indicative of an operating procedure. A plurality of executions of the operating procedure can then be analyzed. A Multiway Principal Component Analysis (MPCA) model can be utilized to detect one or more abnormalities associated with the operating procedure, in response to analyzing the plurality of executions of the operating procedure, in order to compare, monitor and diagnose an impact of variations in one or more executions of the operating procedure.

Claims

1. A computer implemented method for monitoring operating procedures in a production environment, comprising:

compiling data indicative of an operating procedure;

analyzing a plurality of executions of said operating procedure; and

utilizing a Multiway Principal Component Analysis (MPCA) model to detect at least one abnormality associated with said operating procedure, in response to analyzing said plurality of executions of said operating procedure, in order to compare, monitor and diagnose an impact of variations in at least one execution of said operating procedure.

2. The method of claim 1 further comprising monitoring a plurality of statistical outputs from said MPCA model to determine statistically unusual executions associated with said operating procedure.

3. The method of claim 1 wherein said operating procedure comprises a prescribed sequence of activities having an impact on a particular process.

4. The method of claim 3 wherein said operating procedure comprises a start-up sequence of said particular process.

5. The method of claim 3 wherein said operating procedure comprises a shut-down sequence associated with said particular process.

6. The method of claim 3 wherein said operating procedure comprises an emergency procedure associated with said particular process.

7. The method of claim 3 wherein said operating procedure comprise a normal operating procedure associated with said particular process.

8. A computer implemented system for monitoring operating procedures in a production environment, comprising:
