DMDII-15-11 Completing the Model-Based Definition
February 7, 2017
Current industrial implementations of Model-Based Definition (MBD) primarily deal with product geometry, and limited metadata. The use of MBD in manufacturing has been limited compared to its use in design. Moreover, MBD is inherently dependent upon the software application that authors use to create the model. These software applications may or may not be accessible/affordable by small/medium enterprises. All three of these issues need to be addressed in order to support a seamless digital thread throughout the entire product life cycle.
In order to enable additional consumers of information among the stakeholders in the product life cycle, the MBD must address not only shape information, but behavior and life cycle context information as well. This includes such information related to requirements, materials, analysis, manufacturing processes, and operations. MBD should also include process data and the variable as-built data created during the manufacturing life cycle. MBD used throughout the product lifecycle has the potential to reduce cost, increase quality, and enable better (and more accurate) communication within the supply chain and during operation/maintenance efforts. Inclusion of semantic Product Manufacturing Information (PMI), i.e. “smart” PMI, will allow for the extensi on of an unbroken digital thread from function requirements through the as-built record. Model-Based Definition is fundamental to the digital thread, a critical communication conduit for the product life cycle.
Companies spend billions of dollars dealing with inadequate data exchange and interoperability. Too much time and money is spent on non-value added cost avoidance, mitigation activities (i.e., repairing data), translators, and other human-in-the loop tasks. The lost opportunity costs are staggering. There is significant need for software application independent product model definition for defining assemblies, parts, attributes, and manufacturing information (e.g. PMI) that is ingestible by various software (in a heterogeneous software environment) for CAD design, analysis, fabrication, assembly, test, sustainment, i.e., the whole product life cycle.
DMDII is seeking project White Papers to demonstrate Model-Based Definition (MBD) as the key to gathering, organizing and managing product/process data within the Digital Thread. The Offeror should demonstrate information flow along the Digital Thread including one or more life cycle stages such as design to manufacturing. This project call will focus on seamless flow of the MBD information characterized by a heterogeneous software application environment and sufficient information content to accomplish life cycle activities. Potential life cycle activities for this project call should focus on enabling the Digital Thread in these areas:
- MBD for Detail Design
- Manufacturability & Affordability Analysis
- Design to Manufacturing
