Process Evaluation Tool system collects and processes information for a user-defined time intervals and generates production yield, defect, throughput, and SPC charts, presented by data-driven ergonomically designed displays. Those time intervals get advanced by a user-specified rate as time progresses, resulting in presenting streaming overlapped display contents. The system also generates periodic tabular reports (available in HTML [for viewing] and PDF [for printing] formats) along with creating web-listed links to them as time-interval names.

Those intuitively driven, drill-down displays are executed by a platform-independent internet browser with no additional client software required.

Real time charts and reports, available for viewing and printing over the Internet, unlock the full potential of statistical process evaluation.

Equipment Performance

The displays are generated for entities such as plant, product, equipment type, machine, work cell, step, operation, and part. Each manufactured part within the system is represented as a 3D-approximated object carrying the essential information allowing generating the fundamental SPC charts:

Yield and throughput histograms (with SPC-limit marks)

Defect/Error distribution

Pareto analysis

Normal distribution for each measured parameter

Parameter correlation vs. other parameter

Product/machine trend over time within work cells

Equipment /product trend over time within a work cell

XR charts

Lot defects histogram

Surface defect distribution and defect counts

Equipment utilization graph (relevant to a time interval)

Last 20 manufactured unit’s status (along with measured parameters) table

Alarm table showing last 30 parts that violated SPC rules (per product)

Overlapped 2-hour/shift/day/week/month yield/SPC reports

Process Evaluation Tool is a customizable suite of analytical applications that requires no maintenance efforts, saves valuable production resources, and maximizes profitability.
