State Statistics (Pro)

State Statistics provides production state tracking with time-based statistics collection for OEE analysis, bottleneck identification, and performance monitoring.

Overview

Section titled “Overview”

The StateStatistics component tracks how much time objects spend in different states, enabling Overall Equipment Effectiveness (OEE) analysis and production optimization.

Key Features

Section titled “Key Features”
  • State Time Tracking – Measure duration in each production state
  • OEE Calculation – Support for availability, performance, and quality metrics
  • Bottleneck Identification – Identify which states consume most time
  • Real-Time Monitoring – Track statistics during simulation runtime
  • Export Capabilities – Generate reports from collected statistics

Common Production States

Section titled “Common Production States”

Typical states tracked in industrial automation:

  • Idle – Waiting for material or instructions
  • Processing – Active production or handling
  • Blocked – Cannot proceed due to downstream issues
  • Starved – Waiting for upstream material delivery
  • Maintenance – Under maintenance or repair
  • Error – In error state requiring intervention

Usage Examples

Section titled “Usage Examples”

Basic State Tracking

Section titled “Basic State Tracking”
// StateStatistics component tracks state changes automatically
// Configure which states to monitor in Inspector

OEE Analysis

Section titled “OEE Analysis”

Statistics collected can be used for:

  • Availability = (Total Time - Downtime) / Total Time
  • Performance = Actual Output / Theoretical Maximum Output
  • Quality = Good Parts / Total Parts Produced
  • OEE = Availability × Performance × Quality

Common Applications

Section titled “Common Applications”
  • Production Line Analysis – Identify inefficiencies in manufacturing processes
  • Bottleneck Detection – Find which stations limit throughput
  • Shift Performance – Compare productivity across different time periods
  • Continuous Improvement – Track impact of process changes over time
  • Capacity Planning – Understand actual vs theoretical capacity

Integration Points

Section titled “Integration Points”
  • Integrates with StatDisplay for visualization
  • Compatible with DES simulation for accelerated analysis
  • Exports to standard reporting formats
