Production Routing

Summary

A production routing defines the creation of a product by combining multiple pieces of different materials in a series of operations ordered in a specific sequence and executed at a work center.

A production routing allows the system to calculate production costs, durations, and resource requirements per operation and in aggregate.

Data Model

---

Relationships

1. A Production Routing references a Product
2. A Production Routing can have multiple Operations
3. An Operation is assigned to a WorkCenter (machine, person, resource, etc)
4. An Operation can have multiple OperationResourceConsumptions

Assumptions

1. Byproducts, i.e. left overs from the process that still has value. A separate line item is captured in the BOM with a negative quantity
2. Consumables are not recorded in the Bill Of Materials.
