Automated
Process data collection and application of SPC Rules
TYNE's Web-based SPC system receives information from
multiple in-line processes, loading the data into the
System database. Then each data point (sample) is
automatically compared versus the User defined Control
Limits and applicable WECO rules.
Should an Out of Control (OOC)
situation be determined, an Alarm condition will occur, the
Event is logged into the database and the responsible
process owner alerted via the existing IT infrastructure.
SPC
Alarms
for timely containment of Abnormal process results
However the User need not wait for notification, the System
also provides a very visual method to highlight which steps
are running in Control. The User can 'drill-down' on
the operations with current OOC conditions.
Once the Alarm condition has been raised or
noted, it is then the responsible Engineers’ role to
review the OOC event, disposition it accordingly
and release the process back to ‘Production’.
Several options are
provided for the engineers to analyse the events and
disposition them, adding comments as necessary.
All events and dispositing is recorded in a
historical database for review or later analysis.
SPC
Offline
analysis for Long term Continuous Improvement
After several days of production it is possible to
start to perform offline analysis. Options
include simulating different SPC rules (limits &
WECO rules) on the data for fine tuning
the setup. Alternatively the User can
understand the event breakdown for the different OOC
conditions. For example, a pareto to
highlight the areas needing the most attention
first, Cpk reports and OOC History reports.
Several options exist for manipulating the SPC
data including some simple EDA functions, reports
and data export tools.
