| Research Abstract |
In order to measure the degree of reliability of large scale software systems, many software reliability assessment models have been proposed by many researchers so far. In such a situation, we have developed several simulation models to assess software reliability based on the time series data. Especially, we provide a calibration scheme of control parameters included in the software reliability simulator. The control parameters are calibrated so as to minimize the mean sum of squared errors between the actually observed data and the generated ones by the simulator. We showed several numerical examples of the calibration and software reliability assessment by the proposed scheme. We confirmed that these results met our aim.
