Custom-Bike Production with Sustainability Data

Description #

This synthetic object-centric event log models the production and delivery of custom-configured bikes. It was created as the illustrative example for the paper Object-Centric Process Mining for Semi-Automated and Multi-Perspective Sustainability Analyses, published at ICT4S 2025, pp. 143–152.

The example combines process data with sustainability information so that environmental impacts can be assigned to events and allocated to the objects involved in production.

Structure of the OCEL #

The log contains 15 events and 15 objects. Its object types are:

• Bike, Frame, Wheels, and Gears for the manufactured product and its components;
• Order for the customer order; and
• Truck, Dryer, Packer, and Spray. Inst. for resources involved in production and delivery.

Event types cover order registration and configuration, item picking, frame painting, bike assembly, packing, payment, and outgoing delivery. Typed event and object attributes provide the data needed for multi-perspective sustainability analysis.

Downloads #

The paper’s public repository provides the same OCEL 2.0 log in three serializations:

• JSON
• SQLite
• XML

The repository also includes the example analysis, impact data, and generated visualizations used with the log.

Potential Uses #

The dataset is suitable for experimenting with:

• event-level environmental impact enrichment;
• allocation of shared emissions to process objects;
• comparisons between operational and sustainability perspectives; and
• object-centric process discovery on a compact production example.
