基于结构元理论的FGEOM/FGEOM/1 模糊离散时间排队系统

ompared with continuous-time queue, Discrete time queue is more suitable for the analysis and modeling of computer systems and digital communication network performance. However, parameters in the classic discrete-time queuing system:customers ' average arrival rate λand average service rate μ are all destiny. As λ，μare often obtained by interval estimation,so it is more reasonable to regard λ，μas fuzzy numbers. This paper discusses fuzzy discrete-time queuing system FGEOM/FGEOM/1 in which λ，μ are all fuzzy numbers applying fuzzy structural element theory based on fuzzy discrete-time queuing system FGEOM/FGEOM/1.At last, performance of the unlimited buffer delta network is analyzed by means of the discrete time queue.
