System and method for process monitoring

A method comprising:

• based on data received from a process plant, constructing a multivariate model of a process performed by the process plant, the multivariate model being constructed as the data is received;
• presenting a user interface to a remote user, the user interface displaying the value of a composite variable of the multivariate model over time, the composite variable being created from a plurality of process variables;
• updating the user interface as the data is received;
• receiving a selection of a time point in the composite variable display;
• and
• displaying the contribution of at least one of the plurality of process variables to the composite variable at the selected point.

A computer-readable storage medium storing a plurality of instructions which, when executed by a processor, cause the processor to perform a method comprising:

• based on data received from a process plant, constructing a multivariate model of a process performed by the process plant, the multivariate model being constructed as the data is received;
• presenting a user interface to a remote user, the user interface displaying the value of a composite variable of the multivariate model over time, the composite variable being created from a plurality of process variables;
• updating the user interface as the data is received;
• receiving a selection of a time point in the composite variable display;
• and
• displaying the contribution of at least one of the plurality of process variables to the composite variable at the selected point.

A method comprising:

• constructing a multivariate model of a process described by a plurality of process variables in real time based on data received from a process plant;
• presenting a web-based user interface to a remote user, the interface displaying:
• a composite variable of the multivariate model over time;
• an indication of the contribution of at least one of the plurality of process variables to the composite variable at a time point;
• and
• the deviation of the process from an expected mean trajectory;
• receiving a selection of a time point in composite variable display;
• and
• updating the indication of the contribution of the at least one of the plurality of process variables to display the contribution of the at least one process variable at the selected time point.
