1. Online CPS for Dynamic Modification of Production Lines
The challenges of recent years have included growing geopolitical risk, increasingly diverse customer requirements, shorter cycle times, and a shrinking workforce. In response, it is becoming more important than ever for manufacturing plants to be faster and more efficient in how they commission, operate, modify, and repair production lines. To address this challenge, Hitachi has developed practices for online cyber-physical systems (CPSs) that can dynamically modify the planning and control of production lines in response to demand fluctuations and changes in the plant itself.
While past practice with CPSs has required supervisors to monitor the actual data collected from the production line and consider what actions to take based on the analysis of trends, the problems with this are that analysis requires considerable expertise and it takes a lot of work to formulate a plan of action, during which time the line may be halted. With an online CPS, it is possible to automatically optimize the tasks of detecting anomalies, generating actions, and modifying plans. The result is a faster transition to the new plan, allowing the line to remain in production without shutdowns.
