Analysis of an MMAP/PH₁,PH₂/N/∞ queueing system operating in a random environment

Chesoong Kim, Alexander Dudin, Sergey Dudin, Olga Dudina (2014)

International Journal of Applied Mathematics and Computer Science

Similarity:

A multi-server queueing system with two types of customers and an infinite buffer operating in a random environment as a model of a contact center is investigated. The arrival flow of customers is described by a marked Markovian arrival process. Type 1 customers have a non-preemptive priority over type 2 customers and can leave the buffer due to a lack of service. The service times of different type customers have a phase-type distribution with different parameters. To facilitate the...

Transparent Scheduling of Composite Web Services

Dyachuk, Dmytro, Deters, Ralph (2007)

Serdica Journal of Computing

Similarity:

Composite Web Services (CWS) aggregate multiple Web Services in one logical unit to accomplish a complex task (e.g. business process). This aggregation is achieved by defining a workflow that orchestrates the underlying Web Services in a manner consistent with the desired functionality. Since CWS can aggregate atomic and other CWS they foster the development of service layers and reuse of already existing functionality. An important issue in the deployment of services is their run-time...

Analysis of an MAP/PH/1 queue with flexible group service

Arianna Brugno, Ciro D'Apice, Alexander Dudin, Rosanna Manzo (2017)

International Journal of Applied Mathematics and Computer Science

Similarity:

A novel customer batch service discipline for a single server queue is introduced and analyzed. Service to customers is offered in batches of a certain size. If the number of customers in the system at the service completion moment is less than this size, the server does not start the next service until the number of customers in the system reaches this size or a random limitation of the idle time of the server expires, whichever occurs first. Customers arrive according to a Markovian...
