Performance Indicators
Comprehensive testing and analysis will measure Key Performance Indicators, used to assess batch performance and improvement area potential:
- Batch Cycle Times
- Step and Phase Cycle Times
- Instrumentation and Control Loop Performance
Process Analysis
Each performance indicator includes indicators derived from historical batch data collected over a specific time period. The indicators are used to evaluate the performance level of various aspects of the batch process, including but not limited to:
- Level 1 controls
- Flow, pressure, level, and temperature controllers at different production rates
- Level 2 supervisory controls composition and temperature profiles, satisfaction of product specifications
- Critical product specification limits
- Operating constraints
- Batch control configurations
Identifying the process area(s) that are under-performing is the
first objective in the diagnostic procedure. The robustness of
the diagnostic has a significant impact on the efficiency and
consistency with which the improvements can be achieved. In
order to provide practical solutions for problems often identified
in a batch process, ABB has developed well-defined, logical
optimization procedures.
The process and laboratory data is analyzed to provide the resulting
Key Performance Indicators. Data from multiple batches can be
trended together and KPIs compared. The trends allow for fast
visualization of batch data with the ability to zoom in on periods
of interest.
The batch data analysis helps to identify bottlenecks that limit cycle times. Recommendations help to increase uptime, reduce response times to upsets, and Increase throughput. The results also help to reduce the time needed to investigate quality and equipment issues.
Reporting
A report is provided to disclose the findings and recommendations of the process performance diagnosis. This includes an actionable improvement plan.
