  1. Spring 2009 Project Descriptions ME 546 - Designing Product Families - IE 546 Timothy W. Simpson Professor of Mechanical & Industrial Engineering and Engineering Design The Pennsylvania State University University Park, PA 16802 USA phone: (814) 863-7136 email: PENNSTATE © T. W. SIMPSON

  2. Projects for Spring 2009 • Product Family Metrics • Product packaging study (w/Dr. Shooter @ Bucknell) • SWOT analysis for global product families (w/Dr. Lehtihet) • Design Automation • Modular design using cyberinfrastructure (J. Yoo, Lead) • Tools for product family benchmarking (A. Jain, Lead) • Product family optimization through visualization (L. Slingerland, Lead) • Design for Human Variability (w/Dr. Parkinson) • Product family sizing using Design for Human Variability • “Universal” product family design – theory and practice (also w/Dr. McAdams @ Texas A&M)

  3. 1. Product packaging study • Consumable products such as foods, drinks and pharmaceuticals can not bedifferentiated using visual features • Must rely on “artificial” differentiating characteristics like dyes or shapes • Most rely on packaging to differentiateone product offering from the next • Goal: • Examine the use of commonality metricsto assess packaging • Develop new metricsfor product packaging

  4. 2. SWOT analysis for global product families • Many companies these days compete globally for market share • Market heterogeneity arises from cultural differences as well as different needs in different regions of the world • Products are being designed, developed, and manufactured in multiple countries around the world • In many cases, cost to develop a platformoutweighs savings from outsourcing • Goal: • Investigate the use of SWOT analysisfor companies competing global • Develop new metrics/tools for suchcompanies to use that will broadentheir perspective when making product family design decisions Production Worker’s Hourly wage (2002)

  5. 3. Modular design using cyberinfrastructure • Design is often carried out by geographically-dispersed teams operating on different sub-systems/modules • Recent advances in cyberinfrastructure can facilitate this process provided appropriate advances are made in the supporting IT • Goal: • Investigate the use of web service descriptionlanguage and composition algorithms to supportmodular design

  6. = functions = output = input = geometric information Similar to WSDL UMR’s Design Repository • Develop an suitable interface-oriented representation and apply an automated algorithm for product synthesis

  7. 4. Tools for product family benchmarking • Many companies are now benchmarking families of products in addition to individual product offerings • Tools for product family benchmarking are limited • Matrix-based representations and commonality metrics exists but are not readily available or easily understood by designers • Likewise, algorithms for assessment are varied in their format, I/O, size restrictions, and availability • Goal: • Develop an Excel-basedspreadsheet that • Inputs BOM/assembly • Generates/sorts DSM • Computes GVI and commonality metrics • Demonstrate its use witha suitable product family

Product family optimization through visualization • Product family optimization involves tradeoffs between multiple objectives that are often difficult to weight • Interactive visualization can provide insights that might help • Goal: • Investigate the useof visual-basedoptimization toolsto optimize a product family • Demonstrate itsuse optimizinga family of threeGeneral AviationAircraft

  9. 6. Product family sizing using DfHV • Sizing a product line is usually done by identifying the “big” and “small” and creating sizes to fit everyone in between • Goal: • Develop a method to size a family or products using the principal components of variability in the population • Demonstrate the proposed method on a suitable product family case study

  10. 7. “Universal” product family design • While most products are designed to work across a range of performance-related needs, considerations for “universal” design are typically ignored or left until the end of the product design process • Goal: • Study 5-6 product “pairs” and identify ways in which universal design can be considered during the product family design process, not after

  11. Forming Project Teams • You will work in groups of 4-6 people on each project • Take a minute to think about which project interests you most • Find 4-5 like minded people and form a team • If there is overwhelming interest in one project, then we can run two teams in parallel • Identify a time on Friday (2/20) or Monday (2/23) in PM when your whole group can meet • Schedule a kick-off meeting with me for your team • Between now and then, read papers posted on Angel
