Manufacturing Plant Risk Control for Predictive Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manufacturing plants face inefficiencies and unexpected failures due to inadequate monitoring and maintenance of manufacturing devices, leading to unplanned reductions in output or complete shutdowns, as conventional methods lack real-time, holistic assessments of device conditions and operations.
Innovation Solution
A plant management system collects and analyzes data from sensors dispersed throughout the plant to assess operational characteristics and risks, using risk assessment models to adjust operations and schedule maintenance proactively, optimizing device life and plant output without disrupting production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional monitoring and maintenance methods are used, then device operational efficiency is maintained at basic levels, but unexpected failures occur leading to unplanned reductions in manufacturing output
Solution Approach 1:
The system performs preliminary risk assessment and predictive analysis before device failures occur. By continuously monitoring operational characteristics and analyzing risk factors, the system identifies potential failures in advance, enabling proactive maintenance scheduling that prevents unexpected downtime and maintains manufacturing output.
Solution Approach 2:
The system implements continuous feedback loops where sensor data from plant devices is constantly collected, analyzed, and used to adjust maintenance schedules and operational parameters. This real-time feedback mechanism allows the system to respond to changing device conditions, preventing failures that would otherwise reduce manufacturing output.
2Reliability
If adequate monitoring and regular maintenance are implemented, then device reliability and operational efficiency are improved, but system complexity and monitoring requirements increase
Solution Approach 1:
The monitoring system is designed as a universal platform that can assess risk factors across multiple different device types (refiners, pellet mills, centrifuges, pumps, motors, gearboxes) using a common risk assessment framework. This multi-functional approach consolidates what would otherwise require separate monitoring systems for each device type, reducing overall system complexity.
Solution Approach 2:
The system transforms complex sensor data and operational characteristics into simplified risk scores and maintenance priorities through parameter transformation. By converting multiple device-specific parameters into a unified risk assessment framework, the system maintains high reliability monitoring while presenting simplified information to operators.
3Reliability
If proactive maintenance scheduling is implemented based on risk assessment, then unexpected failures are reduced, but additional data collection and analysis requirements are introduced
Solution Approach 1:
The system extracts only the most critical risk factors and operational characteristics from the vast amount of sensor data, focusing analysis on parameters that most significantly impact device reliability. This selective extraction approach enables effective predictive maintenance scheduling without requiring processing of all available data, reducing information processing overhead.
4Productivity
If real-time risk assessment is performed for all plant devices, then manufacturing output is maximized by preventing failures, but computational resources and analysis time increase
Solution Approach 1:
The system applies different levels of risk assessment intensity to different devices based on their criticality to manufacturing output. High-criticality devices receive continuous detailed monitoring and analysis, while less critical devices receive periodic or simplified assessment. This localized quality approach maximizes productivity protection for essential devices while reducing overall computational burden.

AI summary
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, that can adjust operations of a manufacturing plant based on an assessment of risk to the plant's operations posed by the conditions and/or operations of the different devices in the manufacturing plant. Methods may include obtaining, using a set of sensors, a set of current operational characteristics for a plurality of plant devices in a manufacturing plant. For a particular plant device, a set of risk factors corresponding to a failure of the particular plant device can be analyzed. Based on the set of risk factors, an overall risk posed by the particular plant device to operations of the manufacturing plant can be determined. Based on the overall risk, one or more operations of the manufacturing plant can be adjusted.
