许多年来,自动故障检测和故障隔离已成为武器系统设计的主要目标。其益处已被大家意识到,它包括可以减少培训、测试设备、文件、备件和维修停机时间,这些减少是与不具备自动故障检测和隔离的系统相比较而言的。这些减少对任何重大采购计划都能大量节省寿命期保障费用。由于技术不断发展,自动故障检测和故障隔离能力也会提高,并且可能成为系统设计选择和签合同时的考虑因素。 成功的升级计划中的关系步骤是从寿命期保障前景中抓住识别和综合提高的机会,应当用最新技术来消除主要的维修成本增加因素,从而使寿命期保障费用最少。这种方法必须与最后的设计开发一同实施;更重要的是,它必须成为整个开发和设计过程中要考虑的问题。 美国海军宙斯盾战备状态测试系统(ORTS)的升级计划一贯地使用并行工程原理来确保在主要的设计考虑中包括自动故障检测和故障隔离技术的提高。这些提高与开发过程中的新威胁程度的提高受到同样的重视。这篇论文的目的是共享ORTS升级计划的有益方面并研究所要致力于解决的特殊方面的提高以及其他有关的已被意识到的益处。
For many years, automatic fault detection and fault isolation have become the major goals of weapon system design. The benefits have come to be recognized as a reduction in training, test equipment, documentation, spare parts and maintenance downtime compared with systems that do not have automatic fault detection and isolation. These reductions save significant life-time costs on any major purchase program. As technology continues to evolve, automated fault detection and fault isolation capabilities will also increase and may be a factor in system design choice and contract signing. The steps in the relationship to a successful upgrade plan are to capture the opportunities for identification and overall improvement from the end-of-life assurance landscape and the latest technology should be used to eliminate the major contributors to maintenance costs and thereby minimize lifetime support costs. This approach must be implemented together with final design development; more importantly, it must be a consideration in the overall development and design process. The ORS Upgrade Program consistently uses parallel engineering principles to ensure that automatic fault detection and fault isolation techniques are included in major design considerations. These improvements and improvements in new threats in the development process receive the same attention. The purpose of this paper is to share the benefits of the ORTS Upgrade Program and to study the specific aspects of the improvements that are being addressed and other relevant and perceived benefits.
