A method of alarm notification includes providing data for an industrial process including stored alarm event data and stored Key Performance Indicator (KPI) data, and an alarm event-KPI correlation and operator notification system. Patterns of relationships are discovered between the stored alarm event and KPI data to provide a reference pattern database that identifies KPI violation events in the KPI data as a function of the alarm event data or alarm events in the alarm event data as a function of the KPI data. Pattern matching uses a real-time alarm event and real-time KPI data to determine a pattern similarity by comparing a current sequence spanning a predetermined time of the real-time alarm event and KPI data to the patterns. When the pattern matching identifies a current alarm event or KPI violation event, an operator is notified and a predicted KPI value or feature or a predicted alarm event.

Process performance issues and alarm notification using data analytics

A method of tuning alarm parameters for condition monitoring of processing equipment in an industrial processing facility (IPF). For a selected process variable a first histogram is displayed from stored historical process data. An initial process alarm threshold is overlayed on the first histogram, and ON-time delay alarms are computed using an initial zero ON-time delay that would have occurred. A second histogram displays a distribution of alarms run length from alarm event data with the zero ON-time delay. Alarm tuning adjusts the initial process alarm threshold and/or the initial time delay, and an alarm performance is then evaluated from viewing the first and second histogram or viewing a hybrid display providing a time series plot including alarm event and process data, and the adjusting is repeated until the evaluating is deemed satisfactory. The new alarm tuning values are implemented to a control system of the IPF.

Alarm tuning using alarm and process data for condition monitoring

A system for reducing environmentally harmful emissions from an internal combustion engine. The system may incorporate an exhaust after-treatment device. The exhaust after-treatment device may use selective catalytic reduction to remove certain emissions from the exhaust of the engine. Urea solution may be inserted into the exhaust emissions, which is decomposed to ammonia to become a reduction agent for reduction of NOx in the emissions. The engine may be managed by a controller and the exhaust after-treatment device may be managed by another controller. These controllers may be cascaded, or be managed by a third controller that provides hierarchical or coordinated control of engine performance and emissions reduction. The engine and the exhaust after-treatment device may be modeled to aid in designing and building a system for coordinated control of an actual engine and a selective catalytic reduction after-treatment device. The controllers may be predictive model controllers.

Coordinated engine and emissions control system

A method and system for configuring a model of a process. A model of a process is provided, which follows a particular sequence. Such a model includes a plurality of component sub-models, wherein each component sub-model among the component sub-models includes one or more input variables and one or more output variables. Such a method and system also generally includes automatically assigning one or more output variables to one or more input variables based on information associated with the particular sequence of the process.

An engine control unit having a one-time integration of a model predictive control template via a potentially long software process. Changes to the control structure may subsequently be made via a calibration dataset connected to the engine control unit without incurring the potentially long and laborious software process of implementing the template of other approaches in the related art.
