Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for calculating new experimental values for mixture synthesis often result in candidates that do not satisfy allowable conditions, leading to failed experiments and increased costs due to inefficient use of synthesizer facilities.
Innovation Solution
An information processing apparatus performs multi-objective optimization using penalty terms based on a first model for mean and deviation values, and a second model for allowable conditions, to generate effective experimental value candidates.

Engineering Contradiction Analysis
1Reliability
If existing methods for calculating new experimental values are used, then experimental value candidates can be generated, but the candidates do not satisfy allowable conditions leading to failed experiments
Solution Approach 1:
The patent applies preliminary action by performing multi-objective optimization before actual experiments to generate candidate experimental values that satisfy allowable conditions. The system calculates multiple objective functions (including synthesis probability, conductivity, and allowable condition satisfaction) in advance, and selects candidates that meet all conditions before experimentation begins, thereby preventing failed experiments due to condition violations.
Solution Approach 2:
The patent changes parameters by introducing multiple objective functions with different weights to balance competing requirements. The system adjusts the weights of different objective functions (synthesis probability, conductivity prediction, allowable condition satisfaction) to generate optimal experimental value candidates that satisfy all conditions while maximizing productivity and reliability.
2Measurement precision
If multiple composition ratios are tested through experimentation, then appropriate composition ratios can be found, but the process is inefficient and increases costs
Solution Approach 1:
The patent replaces the mechanical experimentation system with an information processing system that uses multi-objective optimization algorithms. Instead of physically testing multiple composition ratios through synthesis and measurement, the system calculates optimal candidates using trained models (synthesis probability model and conductivity prediction model) and selects the best candidates computationally, thereby reducing experimentation time while maintaining or improving optimization accuracy.
Solution Approach 2:
The patent uses copying by creating virtual models of the synthesis process and conductivity measurement through trained machine learning models. The synthesis probability model and conductivity prediction model serve as virtual copies that simulate the outcomes of actual experiments, allowing the system to evaluate multiple composition ratios computationally before performing physical experiments, thus reducing the number of actual experiments needed.

AI summary
A storage medium storing a program that causes a computer to execute a process that includes acquiring a first model that is trained based on training data which indicates a first combination of constituent values of a target object and an environmental value in an experiment on the target object with associating with a characteristic value and that specifies a mean value and a deviation value of the characteristic value; acquiring a second model that is trained based on training data which indicates a second combination of the constituent values and an allowable condition for the experiment, and that specifies the allowable condition; and generating a solution set for the first combination by performing multi-objective optimization by a penalty term based on the allowable condition, a first objective function, and a second objective function.
