Abstract: An online data driven computerized procedures system that guides an operator through a complex process facility's operating procedures. The system monitors plant data, processes the data and then, based upon this processing, presents the status of the current procedure step and/or substep to the operator. The system supports multiple users and a single procedure definition supports several interface formats that can be tailored to the individual user. Layered security controls access privileges and revisions are version controlled. The procedures run on a server that is platform independent of the user workstations that the server interfaces with and the user interface supports diverse procedural views.

Abstract: A system for controlling a complex process in which a supervisory sequential controller interface provides automatic sequencing of a plurality of sequential steps of a procedure for operating the complex process, and a display in dynamic communication with the supervisory sequential controller interface and responsive thereto, displays an overview of the status of progression through the sequential steps relative to the entire process. The display provides a global view of the status of the procedure identifying the state of substantially each criterion that needs to be satisfied to advance to the next sequential step and providing verification that substantially each command to be given upon satisfaction of the criterion, has been executed.

Abstract: A Supervisory Sequential Controller Interface (SSCI) provides for automatic and manual sequencing of the sequential steps of multiple procedures simultaneously in a complex process facility while preserving operator supervisory control over each procedure. The SSCI includes an Executive Interface which gives the operator global control over all of the procedures and a Procedure Interface which is arranged such that the operator may ascertain the relevant information about a particular procedure, including the mode (auto/manual), the current step being executed and the relevant states of plant components and parameters for the current step. Multiple Procedure Interface screens may be displayed to monitor/execute multiple procedures running simultaneously.

Abstract: The present invention is a method for monitoring the operation of a nuclear power facility by generating a composite equation from a relational database which at execution time represents paper procedures. After generating the composite equation, a program stack is compiled on-line from the composite equation. Then, the program stack is executed and sensors are monitored to determine whether an emergency situation has occurred in the facility. When a determined violation has occurred, corrective actions are displayed for a plant operator to execute in order to correct the problem.

Abstract: A computer based system aids an operator in proceeding step-by-step through procedures for a complex process facility. At each step, monitored plant parameter values are used to evaluate relevant plant status and recommend action to be taken. The status and recommended action are presented to the operator on a display device together with prompts for generating appropriate responses. The step logic is carried out repetitively to provide the operator with feedback and to verify operator actions. The complete display picture including operator responses, and other plant conditions monitored in parallel with the current step, is logged for later review. An online review feature permits review of plant conditions and operator actions while the operator continues to execute the procedure. High-level textual statements of all steps of a current procedure can be reviewed and prior steps can be executed or re-executed.

Abstract: The operator of a complex process facility is aided in executing step by step procedures by a computer based system which incorporates monitored plant data and interactive plant operator responses to prompts to progress step by step through selected procedures. At each procedure step the plant status is evaluated and a recommended course of action is identified. The results are displayed on a visual display device to provide operator guidance for executing the procedure in effect. Parallel process monitoring visually alerts the user to conditions not considered by the current step of the active procedure, and where the seriousness of the other condition warrants, provides procedure-based recommendations for priority action. The system can be accessed by multiple users at separate locations for coordinated execution of a single procedure or simultaneous execution of two different procedures.
