带负顾客、启动期和反馈的M／M／1／N多重工作休假排队系统

摘要

研究了带有正、负顾客且顾客容量有限的 M/M/1/N多重休假排队系统，引入不耐烦、空竭服务、反馈和启动期策略，同时假设服务台可能发生故障。利用马尔科夫过程理论建立系统稳态矩阵方程组，并利用矩阵几何解和分块矩阵方法得到了稳态概率的矩阵解，求出了系统稳态下的一些性能指标。最后运用M atlab软件进行数值分析，为系统的优化设计提供参考。%This paper studies an M/M/1/N multiple working vacation queuing system with limited capacity , in w hich customers are either “positive” or “negative” , introducing impatient strategy , exhaustive service , feedback and set-up time , simultaneously assuming desk may malfunction . The matrix form solution of steady-state probability is derived by the Markov process method , and the steady-state probability in matrix form is derived by using matrix-geometric solution and block-matrix-solution method , some reliable indices of the steady-state system are given . Finally , the corresponding numerical analysis is made by Matlab ,which would provide a basis for optimal design .
