Design Heuristic for Parallel Many Server Systems under FCFS-ALIS
We study a parallel service queueing system with servers of types s1, . . . , sJ , customers of types c1, . . . , cI , bipartite compatibility graph G, where arc (ci, sj) indicates that server type sj can serve customer type ci, and service policy of first come first served FCFS, assign longest idle server ALIS. For a general renewal stream of arriving customers and general service time distrib...
متن کاملHeavy-traffic Limits for Polling Models with Exhaustive Service and Non-fcfs Service Order Policies
We study cyclic polling models with exhaustive service at each queue under a variety of non-FCFS (first-come–first-served) local service orders, namely last-come–first-served with and without preemption, random-order-of-service, processor sharing, the multiclass priority scheduling with and without preemption, shortest-job-first, and the shortest remaining processing time policy. For each of th...
متن کاملBenefits of Alternating FCFS/SJF Service Order
We apply simulation to evaluate the performance of scheduling according to an alternating FCFS/SJF service order, in particular concerning performance metrics other than delay. Metrics related to social justice, also referred to as quantitative fairness measures, are investigated. We focus on two types of situations that have been previously identified to provoke and increase queued customers’ ...
متن کاملPreservation of Stochastic Orderings of Interdependent Series and Parallel Systems by Componentwise Switching to Exponentiated Models
This paper discusses the preservation of some stochastic orders between two interdependent series and parallel systems when the survival and distribution functions of all components switch to the exponentiated model. For the series systems, the likelihood ratio, hazard rate, usual, aging faster, aging intensity, convex transform, star, superadditive and dispersive orderings, and for the paralle...
متن کاملDesign and evaluation of overloaded service systems with skill based routing, under FCFS policies
We study an overloaded service system with servers of types S = {s1, . . . , sJ}, serving customers of types C = {c1, . . . , cI} under FCFS. Customers arrive in Poisson streams, join the queue and then abandon or get served. Service is skill based, which is described by a compatibility graph G, where (i, j) ∈ G if server type sj is trained to serve customer type ci. The service duration depend...
