A redundancy allocation problem with the choice of redundancy strategies by a memetic algorithm
This paper proposes an efficient algorithm based on memetic algorithm (MA) for a redundancy allocation problem without component mixing (RAPCM) in a series-parallel system when the redundancy strategy can be chosen for individual subsystems. Majority of the solution methods for the general RAPCM assume that the type of a redundancy strategy for each subsystem is pre-determined and known a prior...
متن کاملRedundancy allocation problem for k-out-of-n systems with a choice of redundancy strategies
To increase the reliability of a specific system, using redundant components is a common method which is called redundancy allocation problem (RAP). Some of the RAP studies have focused on k-out-of-n systems. However, all of these studies assumed predetermined active or standby strategies for each subsystem. In this paper, for the first time, we propose a k-out-of-<em...
متن کاملBin Packing with Queues
We study the best achievable performance (in terms of the average queue size and delay) in a stochastic and dynamic version of the bin-packing problem. Items arrive to a queue according to a Poisson process with rate 2ρ, where ρ ∈ (0, 1). The item sizes are independent and identically distributed (i.i.d.) with a uniform distribution in [0, 1]. At each time unit, a single unit-size bin is availa...
متن کاملQueues with deterministic reneging times
We consider single-server and multi-server queues with deterministic reneging times motivated by the timeout mechanisms used in application servers.. A Volterra integral equation is developed using the level crossing analysis for the M/G/1 queue with reneging. An analytical solution is given for the M/HyperExponential/1 queue with deterministic reneging times and a numerical approach is present...
متن کاملQueues with Nonexponential Failure Times
There are two difficulties with the inclusion of nonexponential failure times in queueing models. The first effect is that the failures will change the mean and variance (as well as higher moments) of the effective service times. The second difficulty is less obvious in that nonexponential failures will eliminate the stochastic independence between successive service times. Using phase-type dis...
