Integrated logistics support analysis of the international space station alpha an overview of the maintenance time dependent parameter prediction methods enhancement

摘要

The objective of this publication is to introduce the enhancement methods for the overall reliability and maintainability methods of assessment on the International Space Station. It is essential that the process to predict the values of the maintenance time dependent variable parameters such as MTBF over time do not in themselves generate uncontrolled deviation in the results of the ILS analysis such as Life Cycle Cost, spares calculation, etc. Furthermore, the very acute problems of micrometeorite, Cosmic rays, flares, atomic oxygen, ionization effects, orbital plumes and all the other factors that differentiate maintainable space operations from non maintainable space operations and/or ground operations must be accounted for. Therefore, these parameters need be usbjected to a special and complex process. Since reliability and maintainability strongly depends on the operating conditions that are encountered during the entire life of the International Space Station, it is important that such conditions are accurately identified at the beginning of the Logistics Support requirements process.
