Event monitor coupled to a quality review system

Abstract

A quality review system may be used to analyze the operation of manufacturing processes within a plant based on data collected by various data sources in the plant to automatically detect, store and display predetermined conditions within the process effecting the quality of the product produced by the plant. The quality review system includes a configuration application that enables a user to create one or more monitoring rules, a monitoring application that collects data from the process and that uses the monitoring rules during operation of the process to analyze the process data to detect one or more predetermined conditions within the process, and an external receiver that stores and / or uses the messages pertaining to the detected predetermined conditions.

AI Technical Summary

Benefits of technology

The quality review management system is a system that can analyze data from different sources and detect any mistakes or exceptions in the manufacturing process. The system stores this data in a organized way, making it easy for engineers to review and fix any issues. The technical effects of this system are its ability to improve the quality of manufacturing processes and detect and resolve issues quickly.

Problems solved by technology

Process plants that are used to make various types of products, such as food, petroleum, drug, etc. products are generally complex and highly automated.

For example, in many cases, unexpected errors or problems may occur within a batch run, such as batch equipment or raw materials being unexpectedly unavailable, process parameters being out of an expected or desired range, etc.

For example, in many cases, exceptions may only represent minimal or unimportant deviations in the expected batch run that do not result in any or in any significant quality reduction of the produced product according to the quality standards being implemented.

In other cases, exceptions may need to be documented for later review by authorized agencies or by the customer, but may not be severe enough in their effect to result in a significant reduction of the quality of the product.

The process of looking through a batch log file for exceptions is highly tedious and fraught with problems.

In particular, most of the data within the batch log file is not indicative of an exception, and so the quality engineer spends a significant amount (usually most) of the review time looking at data that is not actually associated with any exception.

While the existence of batch process alarms and alerts or notes from the operator that are stored in the batch log file may indicate the existence of an exception, this is not always the case and, of course, not every exception that occurs may be documented with an operator note or may rise to a level that causes an associated alarm or alert to be generated in the control system.

This data acquisition activity can be time consuming and requires additional know-how on the part of the batch quality engineer.

This fact makes it difficult for the quality engineer to have a comprehensive view of any particular batch process.

This all makes it more difficult for the quality engineer to understand the context of an exception without significant data lookup in various other subsystems of the batch process.

These updates take time for the user to get and install, and do not enable users to customize their own systems.

Known review systems are currently unable to interface with or create exceptions based on data provided directly from external software programs, like control systems, safety systems, maintenance systems, etc.

As such, these systems are not able to generate exceptions based on process alarms and alerts, for example.

However, as the reviewer processes the exceptions and scrolls down the list of exceptions as displayed on the user interface, the records may change in the database, and thus the page data may become out of date.

In this case, when the system attempts to present the records on a display screen, various records referred to in the pages may be missing, causing visual data loss or duplication.

In some cases, the user may miss a record going from one page to the next due to the deletion of a record on a particular recovered page.

In other cases, the system may become confused as to where to start a new display page based on missing records that were in the downloaded pages.
