1Reliability
If traditional mathematical programming methods (LP, NLP, MIP) are used to solve optimization problems, then optimal solutions can be found while satisfying constraints, but the approach becomes computationally expensive and inflexible when dealing with stochastic variables and complex decision-making problems
Solution Approach 1:
The patent transforms the optimization problem by changing parameters from deterministic to stochastic variables, enabling the system to handle uncertainty and variability in real-world scenarios. This allows the mathematical models to adapt to dynamic conditions while maintaining solution quality
Solution Approach 2:
The patent introduces a meta-learning framework as an intermediary layer that automatically selects and configures appropriate mathematical programming methods based on problem characteristics. This mediator optimizes the choice between LP, NLP, MIP, and other methods, improving computational efficiency without sacrificing solution optimality
2Reliability
If traditional mathematical models are used with fixed formulations, then solutions can be obtained for specific problems, but the entire process needs to be repeated when problem formulation changes or constraints are relaxed
Solution Approach 1:
The patent performs preliminary analysis of problem characteristics and formulates mathematical models in advance, creating a reusable framework that can accommodate future problem variations. By pre-establishing the optimization structure and selecting appropriate methods beforehand, the system avoids repeating the entire formulation process when constraints or variables change
Solution Approach 2:
The patent creates dynamic mathematical models that can adapt to changing problem formulations and constraints. The system automatically adjusts model parameters, variables, and solution methods in response to problem changes, eliminating the need to restart the entire optimization process while maintaining solution accuracy
3Loss of information
If what-if analysis is performed to achieve optimized solutions, then sensitivity analysis capability is improved, but the analysis becomes computationally expensive as the number of variables grows to millions
Solution Approach 1:
The patent applies partial action by performing what-if analysis selectively on critical variables and constraints rather than exhaustively analyzing all million-plus variables. The meta-learning framework identifies which parameters most impact the objective function and focuses sensitivity analysis on those key elements, maintaining comprehensive sensitivity understanding while dramatically reducing computational resource consumption
