Data Driven Simulation

Data-Driven Simulations

Composabl enables you to build simulations from historical data. These simulations are used to train and evaluate multi-agent systems in high-fidelity environments that reflect your actual operations.

Use cases include modeling equipment behavior, logistics workflows, and process automation.

  • Minimum: 3 months

  • Preferred: 1 year (especially for systems with seasonal variation)

Datasets will likely yield a successful simulation when they reflect a >80% accurate relationship between control actions (operator adjustments) and sensor readings.


1. CSV Data Format

Upload a CSV file where each column follows a naming convention:

Variable Type
Prefix
Example

Sensor

s_

s_T (temperature)

Action

a_

a_dTc (cooling delta)

Other Input

(no prefix)

Datetime

Sensors are variables that provide information about the environment or conditions within the process. These may be reported by the machine being controlled or they may come from outside systems. Quality measures such as the results of lab tests are also sensors.

Actions are variables that describe the adjustments the operator makes to the system controls.

Optionally include a timestamp column in UTC. If omitted, Composabl assumes the rows are sequential time steps.

Not all fields need values for every row. The simulator recognizes when data is collected at different intervals.

Units Row (Optional)

Include a row above your column headers to define units for each variable:

kmol/m3,K,K,,kmol/m3,K
s_Ca,s_T,s_Tc,s_Tref,s_Cref,a_dTc
…data rows…

2. Data Configuration

After uploading your CSV file, Composabl guides you through a configuration screen where you confirm the role and type of each column:

Field

Description

User variable name

Rename your variables for clarity (optional)

Mode

Sensor / Action / None (for reference values)

Type

Box or continuous variables

Value Range

Auto-calculated from your data

Unit (optional)

Populated from the units row


3. Simulation Creation Flow

🛠 Step 1: Upload CSV

  • Navigate to the Data-Driven Simulator section.

  • Name your simulation.

  • Upload your CSV file in the proper format.

🧭 Step 2: Configure Variables

  • Review detected variables.

  • Adjust mode, type, unit, and value range if needed.

📊 Step 3: Review Data Score

Composabl will scan your data and generate a Data Score from 0 to 100:

Score Range

Meaning

80–100

Good quality – Ready to simulate

Below 80

Needs improvement – Add data or clean inputs.

🚀 Step 4: Create Simulation

Click Next, and your simulation will be created. It will now be available in your workspace for training, testing, and analysis.


4. Best Practices

  • Use consistent naming: Prefix sensors and actions properly.

  • Include a units row: This improves interpretability and ensures correctness.

  • Handle missing data: Some missing values are fine, but complete coverage of key variables improves accuracy.

  • Timestamps (optional): Include UTC timestamps if events need temporal alignment.


5. Example File

📁 Download sample data:

ple.csv

Use this example file, which contains data, to create a Chemical Process Simulation and see the expected structure, naming conventions, and units in action.


6. Troubleshooting

Problem

Cause

Fix

Variable not detected

Missing prefix

Use s_ for sensors and a_ for actions

Low data score

Not enough data, missing values

Add more historical data or fill in key columns

Unit not recognized

Unit row missing or misaligned

Add units row directly above the variable row
