A parallel server system is a queueing in which jobs are routed upon their arrivals to one of several buffers, each handled by different server. The main operational and theoretical problem such systems find an efficient routing policy that maximizes throughput (or minimizes waiting times). paper “Stability Parallel Server Systems” considers large class policies, includes the most prevalent pol...

Proper arrangement of facility layout is a key issue in management that influences efficiency and the profitability of the manufacturing systems. Parallel Row Ordering Problem (PROP) is a special case of facility layout problem and consists of looking for the best location of n facilities while similar facilities (facilities which has some characteristics in common) should be arranged in a row ...

investigation of reliability characteristics under fuzzy environments is proposed in this paper. fuzzy weibull distribution and lifetimes of components are using it described. formulas of a fuzzy reliability function, fuzzy hazard function and their α-cut set are presented. furthermore, the fuzzy functions of series systems and parallel systems are discussed, respectively. finally, some numeric...

The coarse-grainded architecture model has been proposed to be a model of iently close existing parallel machines. Under this model we design a ommunication-efficient parallel algorithm for the solution of tridiagonal linear systems with n eq indicating the efficiency and scalability of proposed algorithm.
