Equipment Recovery Prioritization Using Downstream Productivity Impact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional production monitoring systems struggle to sufficiently improve productivity when multiple machines are stopped.
Innovation Solution
An equipment recovery notification method that estimates the productivity of subsequent-process equipment based on components produced by stopped equipment, identifies a target equipment for recovery work, and notifies the appropriate personnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional production monitoring systems determine priority based on comparing production quantity with target value, then the system can identify stopped machines, but productivity cannot be sufficiently improved
Solution Approach 1:
The patent introduces an estimator as an intermediary component that calculates productivity information by synthesizing data from multiple sources (production quantity, target value, stoppage time, subsequent process equipment status). This intermediary processing layer transforms raw data into actionable priority information, enabling sufficient productivity improvement without excessive system complexity
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring production status, comparing actual production quantity with target values, and using this information to dynamically adjust priority determinations. The notification system provides feedback to operators about which equipment should be recovered first, creating a closed-loop system that drives productivity improvement
2Productivity
If multiple machines are stopped and all are treated equally, then the monitoring system remains simple, but recovery efficiency and productivity improvement are insufficient
Solution Approach 1:
The patent segments the recovery process by dividing stopped equipment into priority groups based on their impact on subsequent process equipment. Instead of treating all stopped machines equally, the system calculates individual productivity information for each piece of equipment and notifies operators of recovery priorities in sequence, making the complex recovery process manageable and efficient
3Productivity
If the system only monitors current process equipment, then the monitoring scope is narrow and simple, but the impact on subsequent process productivity cannot be fully assessed
Solution Approach 1:
The patent merges information from multiple sources including current process equipment status, subsequent process equipment status, production quantities, and target values into a unified productivity assessment. The estimator combines these diverse data elements to calculate comprehensive productivity information that reflects the overall impact on production, enabling accurate priority determination across the entire manufacturing system

AI summary
An equipment recovery notification method includes: when two or more units of equipment among units of equipment that execute a first process are stopped, estimating, from among one or more units of subsequent-process equipment that execute a second process subsequent to the first process, a productivity of one or more units of the subsequent-process equipment that use at least one of components produced by the two or more units of equipment; identifying one unit of equipment among the two or more units of equipment as target equipment for recovery work, based on the productivity of the one or more units of subsequent-process equipment; and notifying of the identified target equipment.
