ENBIS: European Network for Business and Industrial Statistics

Design of Experiments Special Interest Group

A meeting of the SIG was held during ENBIS8 on 23/9/2008.

In that meeting we discussed several ideas on how to go forward, including a proposal by Ian Cox from JMP Europe to involve ENBIS members in assessing JMP products and elicit user requirements.

Jackie Aasher, who has significant experience with JMP, proposed to prepare in depth reports to JMP.

Daniele Romano was interested in evaluating JMP and other software products.

John Tyssedal also expressed similar interest.

We also discussed the future ENBIS-EMSE spring conference which is focused on simulation experiments. For more details see http://www.emse.fr/enbis-emse2009/

Case studies on design of experiments

The ENBIS working group "Design of Experiments" collects case studies for the benefit of ENBIS members. Case studies are available for ENBIS members only. For submission of case studies, please read the guidelines.

List of currently available case studies

• Seat belt retraction time (only available for ENBIS-Members) (Ulrike Grömping, Carsten Bazant; both Ford Motor Company) (PDF-file).
  Key words: Fractional factorial experiment; limitation on available parts; up-front planning of possible extended experiment

Rules for case studies

At it's Oslo meeting, the working group fixed the following protocol for submitting case studies:

1. Introduction and background
2. Main objections of the experiment
3. List of factors with important factors highlighted
4. List of responses
5. Issues to do with constraints
6. Possible initial model
7. Possible initial design
8. Main design
9. Modelling and allowances
10. Points for discussion

Please take this protocol as a guidance when preparing a case study. Case studies can be submitted per e-mail to Ron Kenett. Acceptable formats are HTML and PDF.

NOTE: For any case study provided here, it is possible to obtain the data — at least in a masked version — so that other ENBIS members can replicate analyses or present alternative approaches.
