Modeling for Scheduling and Workflow Analysis in Manufacturing

We are looking to apply a Graph Database to help us understand bottlenecks, resource utilization, latency issues, and other time related issues related to the workflow in a manufacturing production line.

Google searches have not come up with too much:

Manufacturing

Is anyone aware of related work?

I would expect the graph would minimally need to model:

  1. Resources (humans, tool bench (workstations)
  2. Operations (skills needed, duration, required sub-assemblies)
  3. Sub-assemblies (the materials or derivative outputs from each assembly task).

Is there more?
