[New Model]: Bill of Process (BoP)

[dominikoeh]

Resiliency Domain / Modular Production

Model Description

A Bill of Process (BoP) describes the best-practice approach for the production of a product. Detailed information about the processes, process precedence, and process parameters are required to manufacture the product. The exchange of process information between actors requires a standardized representation of the processes, as currently there are often separate, actor-specific forms of process representation.

This standardization effort aims to ease the understanding of process representations from other partners along the value chain by providing a shared model.
The scope of this model is a BoP that exists before actual production starts, therefore named "BoP as planned".
This model is meant to be flexible enough to accommodate a wide range of use cases and is relevant for both: information exchange (external) and internal workflows.
