Engineering Contradiction Analysis
1Measurement precision
If an engineer performs simulation of substrate processing actions to identify throughput-limiting elements, then analysis accuracy is improved, but time consumption and complexity increase
Solution Approach 1:
The patent replaces manual simulation and analysis by engineers with an automated computer-based system that calculates operation rates and identifies throughput-limiting elements automatically, substituting human expertise with algorithmic processing
Solution Approach 2:
The system enables self-service analysis where the plating apparatus automatically identifies its own bottlenecks through automated calculation of operation rates for each processing unit and transfer apparatus, without requiring external engineer intervention
2Measurement precision
If specialized knowledge is required to perform throughput analysis, then analysis quality is improved, but accessibility and ease of operation deteriorate
Solution Approach 1:
The system performs self-service analysis by automatically calculating operation rates and identifying throughput-limiting elements without requiring external expertise, making the analysis accessible to operators without specialized knowledge
Solution Approach 2:
The patent replaces the need for specialized engineer knowledge with an automated computational system that performs complex calculations and identifies bottlenecks through algorithmic analysis of process data
3Measurement precision
If detailed simulation is performed to identify throughput-limiting elements, then identification accuracy is improved, but device complexity increases

AI summary
An element which limits throughput of a plating apparatus is identified. A method for identifying an element which limits throughput of a plating apparatus is provided. The method comprises: a step for creating a time chart which represents process schedules of plural processing units and one or plural transfer apparatuses; a step for calculating, based on the time chart, at least one of an operation rate and a degree of freedom of taking-out with respect to each of elements comprising the plural processing units and the one or plural transfer apparatuses, wherein the degree of freedom of taking-out represents a degree of freedom with respect to timing when the substrate which has been processed can be taken out of one of the processing units; and a step for displaying, with respect to each of the elements comprising the plural processing units and the one or plural transfer apparatuses, at least one of the calculated operation rate and the calculated degree of freedom of taking-out.
