| Abstract |
A performance evaluation system for railroad facilities is being implemented to strengthen safety management and prepare for the continuous aging ofrailroad facilities. By developing a logical ERD (Entity Relationship Diagram) for the implementation of automated railroad facility performance evaluation, we aim to establish an efficient system to predict future performance changes and demands of railroad facilities, enabling timely maintenance and reinforcement of the infrastructure in an efficient manner. The logical ERD is structured with a detailed design applying evaluation method metrics. The evaluation results are calculated by multiplying the evaluation values and the weights of the evaluation items. The system allows for immediate evaluations for all equipment and sections of railway facilities, as well as for evaluation items without modifying the source, and it is designed to easily change the weights to facilitate evaluations. |
