Forecasting the Number of Spacecraft Software Failures

Spacecraft software failures depend on software defects and errors. This paper offers a part of a solution for a software reliability problem by forecasting the failures. Using the experimental data we calculated the optimal quantity of software testing cycles. We used numerical algorithm to make a forecast of software reliability. Our forecast method is based on software failure formation analysis. It predicts the average quantity of software failures taking into account that the defects are eliminated after testing. The examples of typical cases provided in this article show that applying our method results in effective forecasting.
