Knowledge –based Enterprising (KBE) Strategy for LPD – What it is?

What’s wrong with this?
• Knowledge is fragmented
• Subject matter experts (SME) often scarce and busy
• Less uniformity and consistency
• Time-intensive, manpower dependent
• When people retire, information is lost
• Often design is done via trial and error— case-based reasoning

Drawbacks of procedural KBE Strategy for LPD
• Part and product specific
• Hard-coded interfaces
• Cumbersome to maintain
• Incompatible API’s
• External parameter linking issues
• Very sensitive to interface changes (parameters, rules, features)
• Expansions are complex and error prone
• Inflexible

Modular KBE Strategy: Rule-based System
Control Structure
High Level Requirements
Detail Requirements
An assembly of parametric parts, where dependence of one part to another is controlled by a “control structure logic”—whose primary function is to link relationships and attributes throughout a product hierarchy resulting in a product assembly that is associative.

A CATIA V5 implementation
• System Architecture • JustOne system model and common tree
structure
• Generative Rule Bodies • Rule bodies create more rules dynamically on
the tree; asleep until awaken • Retrieve templates; no generative geometry
• Internal Linking • Two generalized automation methods to
