Control chart for waiting time in system of M / M (a, b) / 1 Queueing model

چکیده
Queueing models provide the basic frame work to get the optimum operating policies in production processes and service facilities. In transportation processes involving buses, aero planes, trains, ships, elevators and so on, bulk service queueing models are often encountered. Control chart technique analyzes the behavior of services and provides the prior idea about expected waiting time, maximum waiting time and minimum waiting time which in turn guarantees customer’s satisfaction. Keeping this in view, the construction of control charts for waiting time in system of M /M (a, b) /1 bulk service queueing model is proposed in this paper.

متن کاملAnalysis of M/G/ 1 queueing model with state dependent arrival and vacation
This investigation deals with single server queueing system wherein the arrival of the units follow Poisson process with varying arrival rates in different states and the service time of the units is arbitrary (general) distributed. The server may take a vacation of a fixed duration or may continue to be available in the system for next service. Using the probability argument, we construct the ...

This paper analyzes a discrete-time $Geo/Geo/c$ queueing system with multiple working vacations and reneging in which customers arrive according to a geometric process. As soon as the system gets empty, the servers go to a working vacations all together. The service times during regular busy period, working vacation period and vacation times are assumed to be geometrically distributed. Customer...

In this paper we develop a multi-objective model to optimally control the lead time of a multistage assembly system. The multistage assembly system is modeled as an open queueing network, whose service stations represent manufacturing or assembly operations. The arrival processes of the individual parts of the product, which should be assembled to each other in assembly stations, are assumed to...
متن کاملA New Heuristic Solution Method for Maximal Covering Location-Allocation Problem with M/M/1 Queueing System
We consider the queueing maximal covering location-allocation problem (QM-CLAP) with an M/M/1 queueing system. We propose a new solution procedure based on decomposition of the problem into smaller sub-problems. We solve the resulting sub-problems both with a branch and bound algorithm and with the meta-heuristic GRASP. We also solve the entire model with GRASP. Computational results for these ...
