Dynamic prediction of risk levels for manufacturing operations through leading risk indicators: dynamic risk analyzer engine
First Claim
1. A system for predicting risk levels for manufacturing operations with risk indicators comprising:
- a server that receives automatically measured process data from a real-time data source and/or a historical archive data source and long-term process data for a period preceding the measured process data;
a processor that analyzes values of parameters P and/or groups G of said parameters P of said measured process data at time interval T and compares the measured process data to the long-term process data wherein the long term process data is automatically updated over time to identify operational risk and/or near-miss risk that would otherwise be unknown or concealed in parameters P, whereby said operational risk and/or near-miss risk may be used for strategic corrective action; and
a display that presents said operational risk and/or near-miss risk in a graphic that visually depicts a plotted value V of parameter(s) P of said operational risk and/or near-miss risk in time interval T relationally within a specified time period;
wherein said system continuously and autonomously operates contemporaneously with said manufacturing operation.

Abstract
The dynamic risk analyzer (DRA) provided by the present invention periodically assesses real-time or historic process data, or both, associated with an operations site, such as a manufacturing, production, or processing facility, including a plant'"'"'s operations, and identifies hidden near-misses of such operation, when in real time the process data appears otherwise normal. DRA assesses the process data in a manner that enables operating personnel including management at a facility to have a comprehensive understanding of the risk status and changes in both alarm and non-alarm based process variables. The hidden process near-miss data may be analyzed alone or in combination with other process data and/or data resulting from prior near-miss situations to permit strategic action to be taken to reduce or avert the occurrence of adverse incidents or catastrophic failure of a facility operation.

5. A method for dynamic prediction of risk levels in a manufacturing operation comprising:
-
collecting measured process data, comprising;
data automatically collected by a data collection component, located within said manufacturing operation, in either (a) real-time or (b) from an archive server or both;collecting long-term process data for a period preceding the collecting measured data; identifying risk and/or near-miss risk of said manufacturing operation that would otherwise be unknown or concealed in parameters P and/or groups G of said parameters P of process data, said process data by comparing the measured process data to the long-term process data, wherein the long term process data is automatically updated over time; and displaying said risk or near-miss risk in a graphic that visually reports a plotted value V of parameter(s) P of said risk or near-miss risk relationally within time T period, whereby said plotted value V is displayed with a variable visual indicator corresponding with magnitude of said plotted value V; wherein said method is performed continuously and autonomously.

6. A display system for risk indicators for a manufacturing operation comprising:
-
identifying risk and/or near-miss risk of said manufacturing operation that would otherwise be unknown or concealed in parameters P and/or groups G of said parameters P of measured process data, in real-time, periodically, and/or historically wherein the measured process data is obtained by using a data collection component located within said manufacturing operation; plotting parameter P of said risk and/or near-miss risk on a circular or semi-circular chart of graphic visual indicators comprising; a petal for P parameter at each T time interval;
said petal comprising an area plotted with a radius R having a maximum and minimum reportable length and an angle spread greater than 1 degree, wherein said length of said radius R corresponds with a magnitude of said parameter P at said T time interval and partially determines said area of said petal displayed on said chart; anddisplaying said parameter P at a time interval on said chart over a predetermined time period.
