Minimizing Error in Predicting the Reliability of On-Board Satellite Systems
Abstract
The reliability prediction process for large, closed (i.e., non- repairable) fault-tolerant, on-board satellite systems is addressed, along with techniques for reduction of error in prediction. Three major error sources are discussed, only one of which can be effectively minimized by modelers. Specific error sources in model construction are identified. It is presented that, although errors exist in the reliability prediction process, complete accuracy is not required for effective use of the predictions in the design process. A set of three tools (CARE III Bavu 84a, Bavu 84b), (HARP HARP 89), and CRAFTS(CRAF 88) are used to model an example on-board system design to illustrate minimization of errors. Guidelines for selecting the proper reliability tools are also given.
