A Proposal for Improving the Results of the Reliability Analysis and FMEA/FMECA of the CBERS Satellite Program 2010-36-0324

Complex systems such as satellites, aircrafts, automobiles and air traffic controls are becoming increasingly complex and highly integrated as prescribed by the SAE ARP 4754 Standard. They integrate many technologies and they work in very demanding environments sometimes with little or no maintenance due to the severe conditions of operation. To survive such harsh operating conditions, they require very high levels of reliability, to be reached by a diversity of approaches, processes, components, etc. By their turn, the processes of analysis and decision making shall be improved progressively, as experience accumulates and suggests modifications and adaptations.
According to this philosophy, in this work, we discuss a proposal for improving the results of the Reliability Analysis and FMEA/FMECA of the CBERS Satellite Program, conducted at the National Institute for Space Research-INPE, since 1987. To do that, we detail the following steps: 1) Anticipate components data to obtain failures rates and failures modes; 2) Anticipate results about the Reliability Analysis (Reliability Prediction and Derating Analysis) and FMEA/FMECA (Failure Modes and Effects Analysis/ Failure Modes and Criticality Analysis) during the execution of the project steps; 3) Completely obtain and document all the information needed for the CDR (Critical Design Review).
Based on all that, we intend to show that the steps proposed in this work can improve the processes of analysis and decision making already adopted in the CBERS Satellite Program; and that they may be adapted to other projects of satellites, aircrafts, automobiles and air traffic controls in the aerospace, automotive and information technology industries.
