Selection of Optimal Error Recovery Process using Evaluation Standards in Automated Plants

Plant automation has become increasingly popular in various industries. However, errors are more likely to occur in difficult tasks that are often performed in an automated plant. Such tasks are often returned to the previous step, and re-executed in the event of a large-scale error. Therefore, it is important to decide both the past step to which the task needs to return and the recovery step following its return. In this study, various evaluation standards are used to realize the planning of error recovery, while considering these two factors.
