Description
Telecommunication mechanisms have been conceptualized simply as links between two points to send
signals. Telecommunication networks are, at present, characterized by clusters of nodes, interconnecting
nodes where information is processed and correctly addressed to the output links. The transmission of
messages was assisted by the first telecommunication networks for telegraphy. Mobile phone networks
were then built to build a physical call circuit set up to connect the source and destination for the entire
duration of the conversation. The networks of today are digital and are focused on the dissemination of
signals arranged in blocks, called packets, which are either routed independently along the nodes or
transmitted from source to destination through a virtual path. On the basis of the network hierarchy,
transmission media are usually distinguished. When a customer of a company has any kind of issue, their
first contact with the company is the call center. They give feedback of their issues to the call center and
the call center’s quality service is so important because the service would determine if the customer’s
issue is resolved and if the customer would continue to do business with the company afterwards.
Deciding an optimum number of operators using key performance index is an important factor in optimizing
a communication system. Research carried out show that this optimization can be made using
queuing theory approach. A practical application of optimizing a call center using stochastic queuing
approach is studied in this review. From the research, the optimal number of operators for the call center
was determined for various peak periods considering four performance index measures. The information
gathered shown the importance of using queuing theory model as a deterministic tool for optimizing a
communication system.
