Space systems are typical large and complex systems. Due to the limitation of human's cognitive capability, it is impossible for a single person to keep track of every single detail of such systems. Therefore, it takes a lot of effort to manage the scale and complexity of space systems, while assuring safety and reliability, which are critical to the success of any mission. There are many activities involved in assuring saftey or reliability of the system, and many software tools have been developed to support each of specific activities. However, such tools do not support coordination among different tasks, especially at the knowledge level. This study aims at realizing knowledge level coordination of safety or reliability tools through ontologybased approach.
