Knowledge –based Enterprising (KBE) Strategy for LPD – What it is?
Brian Prasad http://www.KnowledgeSol.com/
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.

Modular KBE Strategy for LPD?

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
pass/exchange information intrapart and interpart

Modular KBE Strategy Implementation: Demo

Demo–Salient points
• Initialize parameters • SmartParts pulled and Rules added • Specs parameters & constraints passed from
“systems” to “subsystems”, to “components,” to “parts” during “decomposition” and vice versa during “aggregation”
• SmartParts were “instantiated” and constraints satisfied
• Solution is reconfigurable for changing spec requirements

Modular KBE Strategy Implementation:
…directly from spec
• Good for early program stages (Quick evaluation of various “alternate designs” scenarios)
• Gets you 80% there and you can finish the rest (20%) in native CATIA mode

Key Benefits
• Knowledge resides in one system and reused widely across the enterprise
• Order of magnitude savings (1:10 ~ 1:100)
• Promotes collaboration & knowledge sharing
• Product independent architecture
• Experts now become knowledge-keepers
• Promotes innovations and creativity
• Good for preliminary studies & portfolio mgt
• Knowledge inside, Lean inside, standards inside, analysis inside, best practices inside
Modular KBE Strategy for Lean Product Development (LPD)
Brian Prasad http://www.KnowledgeSol.com/
Keys to maximizing productivity gains …
• KBE has its own life. Think about integration and interfaces. They are big deal for KBE.
• Holistic view of product development process • Employ a modular, open, and concurrent
strategy for building KBE systems • Think engineering centric versus geometry-
centric; analysis driven, geometry is a by-product
• Follow a knowledge management framework for applying KBE
