GOALI: Capturing, Implementing, and Generating Product Brand Through Shape Grammars

这个Goali项目由卡内基梅隆大学和通用汽车公司联合运营，专注于开发表达产品品牌的计算工具。这项被称为形状语法的技术需要独特的计算机实现方法。这项工作的四个主要贡献将是1)促进形状语法实施的科学，2)进一步理解品牌的逻辑，3)通过与优化搜索策略相结合的数学(效用)函数来阐明美学的设计目标，以及4)自动化设计综合领域的进一步发展。方法如下：1)创建捕捉产品的核心观点的形状语法，在这种情况下是给定品牌的工具。2)提供这些不同观点之间的相互关系。3)使用2D视图之间的相互关系来创建产品及其品牌的3D语法。4)创造计算机技术以实现2D视图。5)详细说明3D实施的技术要求。6)使用基于优化的搜索策略自动生成适合某个品牌的产品。7)使用基于实用程序的决策工具在生成的设计中进行选择并调整自动算法。这项工作的所有发现都是概括性的，其影响甚至超出了汽车行业。目标是帮助公司更好地了解自己的品牌身份，将当代造型置于其历史产品线的背景下，并在工程师和工业设计师/造型师之间提供清晰的沟通。在该项目的整个生命周期中，每年夏天都会有一名研究生延长访问通用汽车的时间。通用汽车实际上将成为这一奖项的试验台。

This GOALI project, jointly run by Carnegie Mellon and General Motors, focuses on the development of computational tools to express product brand. The technology, known as shape grammars, requires unique approaches to computer implementation. The four main contributions from this work will be 1) furthering the science of shape grammar implementation, 2) further understanding of the logic of brand, 3) articulation of design objectives for aesthetics through a mathematical (utility) function in conjunction with optimizing search strategies, and 4) further advancement of the field of automated design synthesis.The approach will be as follows: 1) Create a shape grammar that captures the core views of a product, in this case a vehicle of a given brand. 2) Provide an inter-relation between those different views. 3) Use the inter-relation between the 2D views to create a 3D grammar of the product and its brand. 4) Create computer technology to enable implementation of the 2D views. 5) Specify the technological requirements of a 3D implementation. 6) Use an optimization-based search strategy to automate the generation of products that fit within a brand. 7) Use a utility based decision tool to select among the generated designs and tune the automated algorithm. All of the findings of this work are general, with broader impacts that go even beyond the auto industry. The goal is to help companies better understand their brand identity, place their contemporary styling within the context of their historical product line, and provide a clear communication between engineers and industrial designers/stylists. One graduate student will have extended visits to GM each summer over the life of the project. GM will in effect serve as a test-bed for this award.
