基于上下文的设计（UCBD）是设计界越来越感兴趣的一个领域。使用情境是产品（或服务）的使用场景集，包括产品使用的环境、产品执行的任务类型以及产品购买和运行的条件。在这项工作中，建议在选择建模使用上下文为基础的设计，使用上下文应该是一个客户配置文件的定义中的主要描述符的一部分，除了建模客户的异质性的社会人口属性。随着客户变得更加精通技术和市场教育，目前的选择建模方法在工程设计中可以大大受益于利用丰富的上下文信息存在于产品的使用。在这项工作中，我们提出了一个选择建模框架，基于使用上下文的设计（UCBD），以量化的影响，使用上下文对客户的选择。我们从定义UCBD的分类开始。通过明确建模的使用上下文的影响，产品性能和客户偏好，一个逐步的选择建模过程，提出了支持UCBD。两个案例研究，一个拼图的例子与规定的偏好数据和混合动力电动汽车的例子与显示的偏好数据，证明了将使用环境中的选择建模的需求和好处。
Usage Context-Based Design (UCBD) is an area of growing interest within the design community. Usage context is the set of scenarios in which a product (or service) is to be used, including the environments in which the product is used, the types of tasks the product performs, and the conditions under which the product is purchased and operates. It is proposed in this work that in choice modeling for usage context-based design, usage context should be a part of the primary descriptors in the definition of a customer profile, in addition to the socio-demographic attributes for modeling customers’ heterogeneity. As customers become more technology-savvy and market-educated, current choice modeling methods in engineering design could greatly benefit from exploiting the rich contextual information existing in product usage. In this work, we propose a choice modeling framework for Usage Context-based Design (UCBD) to quantify the impact of usage context on customer choices. We start with defining a taxonomy for UCBD. By explicitly modeling usage context’s influence on both product performances and customer preferences, a step-by-step choice modeling procedure is proposed to support UCBD. Two case studies, a jigsaw example with stated preference data and a hybrid electric vehicle example with revealed preference data, demonstrate the needs and benefits of incorporating usage context in choice modeling.
