| Business DEX (NDLO001):— part_characterization | Date: 2007/10/12 12:27:18 Revision: 1.25 |
Purpose
This NDLO-DEX shall exchange design data chategorizing a part and material items from the development stage through the support stage, as input to management processes, technical analyses and support.
Usage
The NDLO-DEX provides input data for risk and configuration management processes, and for all technical processes of the life cycle stages. Typical usage is to assess allocation of support requirements for product design, and the continuous review of recommendations for support tasks and resources.
This section provides an overview of the business DEXs.
Characterize material list item
A material list item is a part used during the manufacturing process of the product, e.g. a steel plate used for the construction of the hull is a material list item. It is represented as a part in the PLCS model (blue box).
The figure below illustrates how material list items are characterized.
Characterize maintainable part
A maintainable part is an identified part belonging to the installation.
The figure below illustrates how maintainable parts are characterized.
