| Abstract: | An algorithm is proposed to compute the potentials and the performance derivatives through analyzing the steady performance sensitivity problems for an M/E k/1 queuing system. The algorithm is based on its embedded Markov chains. The applications of this algorithm is indicated by simulating an example of communication network. The algorithm can be directly used in on-line performance analyse and optimization for some practical problems, due to the fact that it is based on a single sample path of a queuing system. |
