| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper considers the parametric sensitivity of a software rejuvenation model for transaction systems. The system behavior is described by a quasi birth-and-death (QBD) process with Markovian arrivals, and the software rejuvenation model is represented by a Markov regenerative process (MRGP). The stationary analysis of the MRGP model is based on the embedding Markov chain (EMC) approach. Then the sensitivities of the stationary solution and the performance criteria of interest, i.e., the loss probability of transactions, with respect to all model parameters, are formulated. Finally, a numerical experiment was conducted to illustrate the critical parameters that significantly affect the system performance. | |
