aggregated_event_data

Package for simulating an (assembly) environment where products/devices are traced on an aggregated level.

Features

Production Entity

Production Resources

• Each resource can execute one type of production step (or has one capability)
• Process time is exponentially distributed, with a fixed mean per resource. The process time is (currently) independent of the number of devices processed.

Production entities

• Lot type is based on the operations executed on the lot.

Material Lots

• Shared store with material lots where all production resources have access to.
• Each device 'consumes' one unit of material at a production step.

Controller

• Uses simple heuristic to schedule each lot at a resource with the shortest queue.

Logging

• The logging is based on the EPCIS 2.0 vocabulary.
