专家系统技术正在应用于NASA航天飞机有效载荷的综合设计问题,以达到以前不可实现的设计的自动化水平。NASA航天飞机在其处理有效载荷舱中的实验设备和各种类型的卫星及其配合的能力方面设计得非常灵活。这种灵活性导致了每个有效载荷和实验设备的各种不同的和特殊的工程资源要求,使每次飞行任务单一化,并造成了重复综合设计问题。专家系统能成功地解决这些问题。轨道飞行器有效载荷舱电缆专家系统(EXCABL)是第一个这种成功的系统,它解决了电子维修设备的问题,并且设计生产率提高到20:1。补充的一些专家系统计划要解决其他的有效载荷综合设计问题。每个完整的专家系统都将与其解决设计环境的局部问题相结合。为了解决总的有效载荷综合设备设计问题,这些专家系统将一起工作,从而便于将局部环境集成为一个完整的系统环境。本文叙述了其中三个专家系统,它们解决有效载荷设计问题的方法,以及如何将它们集成起来。
Expert system technology is being applied to the comprehensive design of NASA space shuttle payloads to achieve the level of automation previously unrealizable designs. The NASA space shuttle is designed to be very flexible in its ability to handle the experimental equipment in the payload bay and various types of satellites and their capabilities. This flexibility leads to a variety of different and specific engineering resource requirements for each payload and lab equipment, simplifying each mission and creating a recurring composite design problem. Expert systems can successfully solve these problems. The first such successful system was the Orbiter Payload Cabin Cable Expert System (EXCABL), which solves the problem of electronic service equipment and increases design productivity to 20: 1. Some of the expert systems supplemented by plans to address other comprehensive payload design issues. Each complete expert system will be combined with its solution to local problems in the design environment. These expert systems will work together to solve the total payload complex equipment design problem, thereby facilitating the integration of the local environment into a complete system environment. This article describes three of these expert systems, their ways to solve the problem of payload design, and how to integrate them.
