Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the evaluation index and calculation method are customized or newly set, then the evaluation can be adapted to specific needs, but enormous labor and cost are required to modify the system
Solution Approach 1:
The system automatically generates new evaluation indices by copying and recombining existing evaluation index definitions. When a user needs a new evaluation index, the system retrieves similar existing indices, copies their definitions, and combines them according to user-specified weights and parameters, eliminating the need for manual system modification
Solution Approach 2:
The system provides self-service functionality by automatically generating evaluation indices based on user input parameters. The evaluation index generation unit autonomously creates new indices by combining existing ones according to user specifications, without requiring manual intervention to modify system code or configuration files
2Productivity
If the evaluation index is frequently changed to respond to business environment changes, then the system remains relevant, but the labor and cost for modifications increase
Solution Approach 1:
The system pre-defines multiple evaluation indices and their calculation methods in advance. When business environment changes require new evaluation criteria, the system can immediately combine these pre-defined indices in different ways without requiring time-consuming system modifications, enabling rapid response to changing requirements
Solution Approach 2:
The system dynamically generates evaluation indices based on user input parameters such as weight coefficients and time periods. This dynamic generation capability allows the system to adapt to business environment changes in real-time by adjusting parameter combinations rather than modifying the underlying system structure

AI summary
The present invention assists at work related to the setting of an evaluation index for a vehicle operation plan. A vehicle operation assistance device manages one or more pieces of evaluation information including information regarding evaluation of the vehicle operation plan, acquires setting target information that is information regarding evaluation, the information being intended to be set for the vehicle operation plan by a user, derives a similarity degree between the setting target information and each pieces of the evaluation information, extracts evaluation information on the basis of the similarity degree, receives a setting for information regarding evaluation related to the vehicle operation plan from the user while presenting similar evaluation information which is the extracted evaluation information to the user and generates evaluation information on the basis of a received content. The vehicle operation assistance device provides a user interface for visually presenting a method for calculating an evaluation index included in the similar evaluation information, in a state in which the user can edit the method.
