A feature ontology to support construction cost estimating
2003
Artificial intelligence for engineering design, analysis and manufacturing
Preserved Fulltext
The feature ontology provides the structure for transforming designer-focused product models into feature-based product models that support cost estimating. ...
We also describe the framework we developed that uses the ontology to represent features in a project-independent way so that they can be reused from project to project to create estimator-focused feature-based ...
