This paper presents a knowledge-based approach to facilitate the engineering design process relating to spacecrafts …. Because the design evolves over a long time and typically involves individuals working at different locations and frequently … determining the aggregate time and cost involved in each instance of spacecraft design. A major aspect of such collaboration is …

described in this paper, embodied in the MATE system, provides a framework for making these decisions in the engineering design … process, by eliciting and capturing the goals and desires of every stakeholder in the design process through utility and … repository to focus on various areas of functionality to be used in the design process. The MATE approach will be combined with …
