Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional production scheduling methods are used, then the scheduling process is simple to implement, but the optimization of production time and cost is insufficient
Solution Approach 1:
The patent replaces traditional mechanical scheduling methods with a genetic algorithm-based intelligent optimization system. The production scheduling manager uses chromosomal encoding to represent scheduling schemes, applies genetic operations (selection, crossover, mutation) to evolve optimal schedules, and automatically optimizes production time and cost without manual intervention.
Solution Approach 2:
The patent changes the scheduling approach from static traditional methods to dynamic genetic algorithm optimization. It encodes scheduling parameters (production sequences, resource allocation, time intervals) into chromosomal structures, allowing the system to explore and optimize multiple parameter combinations simultaneously to achieve better production efficiency.
2Reliability
If multiple production resources are coordinated, then resource collaboration is maintained, but the scheduling complexity increases
Solution Approach 1:
The patent segments the complex multi-resource scheduling problem into manageable chromosomal components. Each chromosome represents a complete scheduling scheme that inherently maintains resource collaboration constraints. The genetic algorithm operates on these segmented chromosomes, evaluating and optimizing them while preserving the collaboration relationships among production resources.
Solution Approach 2:
The patent introduces a production scheduling manager as an intermediary between production resources and scheduling decisions. This manager uses chromosomal encoding to mediate resource coordination, automatically handling the complexity of maintaining collaboration among multiple resources while optimizing the overall production schedule.
3Loss of time
If production scheduling is optimized using genetic algorithm, then production time and cost are reduced, but the computational complexity increases
Solution Approach 1:
The patent performs preliminary chromosomal encoding of production scheduling schemes before optimization. By pre-structuring the scheduling parameters into chromosomal formats with built-in constraints, the system reduces the computational search space and enables more efficient genetic algorithm execution, thereby reducing manufacturing time despite the computational complexity of the optimization process.
