Miss Joanne Smith Final Year PhD Student Supervisor: Dr Alex Duffy Research Presentation Day Thursday 24th January 2001 A Holistic Modular Design Methodology Supporting Multiple Views of the Product Development Process

Modular Design System Development Conclusion Introduction RPD ‘2002” Methodology Introduction Introduce Concept of ‘Modular Design’ Issues in ‘Modular Design’ research Discuss System under development  Current functionality - 2 case studies  Current development- Mast case study Conclude Further Work

Modular Design System Development Conclusion Introduction RPD ‘2002” Methodology Modular Design The Modular Concept Module A group of ‘functionally or structurally’ independent entities Never truly independent  Must define together with overall system There are Benefits Efficient upgrades, reduced complexity, reduced costs, rapid product development and improved design knowledge structuring. However Modularity is treated in an abstract form Current lack of systems or approaches to:  Determine modules  Optimise modular design  Represent modularity

Modular Design System Development Conclusion Introduction RPD ‘2002” Methodology Issues Modular Design Benefits Modular Design

Modular Design System Development Conclusion Introduction RPD ‘2002” Methodology Models Concepts (currently components) Dependency knowledge  Weight the dependencies accordingly Analyse Modularity Optimises Component Groupings (modules) Calculate the relative modularity of the optimum component groupings  Produces a Modular Structure Matrix ‘MSM’ System Current Functionality

Modular Design System Development Conclusion Introduction RPD ‘2002” Methodology Case Studies A: Climate Control B: Alternator Concepts (same order – arbitrary) Dependencies (weighting represented by colour) Initial Clustering Value System

Modular Design System Development Conclusion Introduction RPD ‘2002” Methodology Optimised Matrices A: Climate Control B: Alternator Optimum Clustering Value Clear Component Groupings(Modules) System

Modular Design System Development Conclusion Introduction RPD ‘2002” Methodology Modular Analysis A: Climate Control B: Alternator The Modular Structure Matrix Colour represent different degrees of modularity  Dark colour = strong module  Exposes inherent modular hierarchy System Optimal Modular Structure Clustering entities such that the degree of interaction/dependency is  Maximised internally within groups (modules)  Minimised externally between groups (modules)
