Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If operation time information is calculated based on past operation records, then productivity evaluation accuracy is improved, but operators with no past records (new operators, assistants) cannot receive efficient operation instructions
Solution Approach 1:
The system creates a virtual model (standard operator) by copying and aggregating operation time data from multiple actual operators with past records. This virtual standard operator serves as a template that can be applied to any operator including new operators without past records, enabling the system to provide operation instructions universally while maintaining accuracy based on historical data patterns
Solution Approach 2:
The system introduces a standard operator as an intermediary between actual operators with past records and new operators without records. The standard operator acts as a mediator that translates historical operation time data into predictive models for operators lacking personal history, enabling efficient operation instructions to be provided indirectly through this intermediate representation
2Reliability
If operation time information is collected from actual operators, then data accuracy is improved, but data availability deteriorates for operators with no past operation records
Solution Approach 1:
Instead of requiring actual operation records from each operator, the system copies operation time patterns from the virtual standard operator model. This allows new operators to have reliable operation time estimates generated through copying established patterns rather than requiring their own historical data, thus maintaining reliability while improving information availability
Solution Approach 2:
The system performs preliminary action by pre-calculating and storing operation time data for a virtual standard operator before it is needed for actual operators. This advance preparation ensures that when new operators need operation instructions, reliable data is already available in the standard operator model, eliminating the need to wait for new operators to accumulate their own operation records

AI summary
A process plan preparation assistance apparatus includes a personnel assignment calculator to calculate personnel assignment for an element operation corresponding to a production plan indicated by production plan information acquired based on operation time information for each operator, a process plan information generator generate process plan information indicating personnel assignment and a production sequence to maximize an evaluation value for productivity, and an operation time information updater to update the operation time information for an operator with a past operation record based on image information indicating an image of the operator, predict an element operation time of an operator with no past operation record based on the operation time information for an operator with a past operation record who has an attribute most similar to an attribute of the operator with no past operation record, and generate the operation time information for the operator with no past operation record.
