# State Statistics (Pro)

{% hint style="info" %}
This feature was added in realvirtual **6.0.7** (Professional)
{% endhint %}

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

## Overview

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

## 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

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

### Basic State Tracking

```csharp
// StateStatistics component tracks state changes automatically
// Configure which states to monitor in Inspector
```

### 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

* **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

* Integrates with [StatDisplay](https://doc.realvirtual.io/components-and-scripts/scene-interaction/statdisplay) for visualization
* Compatible with DES simulation for accelerated analysis
* Exports to standard reporting formats
