.... have been studied to track the Copyright 1999 by ASME effectiveness and efficiency of existing platforms in order to provide an indication of when products should be redesigned or replaced [15] Model based approaches have also been created to define the content of platforms and variants [11, 16, 26, 27]. Krishnan [11] presented an approach to decide on the placement of product offerings along a dimension of performance. This method applies for products that can be scaled along a single performance attribute that increases with time, such as processor speed; these are called technological ....

....are called technological products in that work. However, many sets of products, such as the spacecraft example shown later in this paper, do not have a single, always increasing desired performance attribute that describes them completely. A second model based approach has been shown by Simpson [26], which can find the appropriate settings for one or more scale factors that describe variants to be derived from a scalable platform. This is a particular type of platform where one or more product features can be scaled (in both design and manufacturing) to form a new variant. However, many ....

....is the development of physics based models of key responses and or constraints as a function of design variables. The scope of this need, of course, depends on the particular product and organization in question. The nominal use of several metamodel techniques is now fairly well understood (Refs. [13, 14]) and increasingly accepted in the aerospace design community. The status of this element of the VSLCDE remains a function of the 5 particular discipline in question. Barriers often include the incompatibility of existing physics based tools with automated or repeated execution necessary for the ....

....product variety within the product family. Based on a similar principle to that of the PPCEM, the Product Variety Tradeoff Evaluation Method (PVTEM) is presented by Conner, et al. 4] to assess appropriate product family tradeoffs using the commonality and performance indices developed in Simpson [25]. In each of the above parametric modeling approaches, the set of the scale factor(s) and that of the common platform parameters are pre selected, and the selection is independent from the commonality and performance tradeoff evaluation model. The objective of this paper is to integrate the ....
