We have developed new algorithms for generating and assessing efficient two-stage group screening strategies which are implemented through a web-based system called GISEL. This system elicits company knowledge which is used to guide the formulation of competing two-stage strategies and, via the algorithms, to provide quantitative assessment of their efficiencies. The two-stage group screening method investigates the effect of a large number of factors by grouping them in a first stage experiment whose results identify factors to be further investigated in a second stage. Central to the success of the procedure is ensuring that the factors considered, and their grouping, are based on the best available knowledge of the product. The web-based software system allows information and ideas to be contributed by engineers at different sites and allows the experiment organizer to use these expert opinions to guide decisions on the planning of group screening experiments. The new group screening algorithms implemented within the software give probability distributions and indications of the total resource needed for the experiment. In addition, the algorithms simulate results from the experiment and estimate the percentage of important or active main effects and interactions that fail to be detected. The approach is illustrated through the planning of an experiment on engine cold start optimization at Jaguar Cars.<\/jats:p>","DOI":"10.1115\/1.1778192","type":"journal-article","created":{"date-parts":[[2004,9,7]],"date-time":"2004-09-07T22:39:45Z","timestamp":1094596785000},"page":"218-225","update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":6,"title":["A Web-Based Knowledge Elicitation System (GISEL) for Planning and Assessing Group Screening Experiments for Product Development"],"prefix":"10.1115","volume":"4","author":[{"given":"David P.","family":"Dupplaw","sequence":"first","affiliation":[{"name":"School of Electronics and Computer Science, University of Southampton, Southampton SO17 1BJ, England"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David","family":"Brunson","sequence":"additional","affiliation":[{"name":"Jaguar Cars Limited, Whitley Engineering Center, Coventry CV3 4LF, England"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna-Jane E.","family":"Vine","sequence":"additional","affiliation":[{"name":"Statistical Sciences Research Institute, School of Mathematics, University of Southampton, Southampton SO17 1BJ, England"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Colin P.","family":"Please","sequence":"additional","affiliation":[{"name":"School of Mathematics, University of Southampton, Southampton SO17 1BJ, England"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Susan M.","family":"Lewis","sequence":"additional","affiliation":[{"name":"Statistical Sciences Research Institute, School of Mathematics, University of Southampton, Southampton SO17 1BJ, England"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Angela M.","family":"Dean","sequence":"additional","affiliation":[{"name":"Department of Statistics, Ohio State University, Columbus, OH 43210-1247, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andy J.","family":"Keane","sequence":"additional","affiliation":[{"name":"School of Engineering Sciences, University of Southampton, Southampton SO17 1BJ, England"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcus J.","family":"Tindall","sequence":"additional","affiliation":[{"name":"Department of Mathematics, University of Oxford, Oxford OX1 3LB, England"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"33","published-online":{"date-parts":[[2004,9,7]]},"reference":[{"key":"2019100610020457900_r1","doi-asserted-by":"crossref","unstructured":"Meyer, M.
