of people, machines and materials waiting
for a process to be performed. In the solution of the problems related to the
waiting line, data such as arrival source, queuing process, service channel and
service delivery process in regard to the system are used. According to the structure
of the problems of enterprises, waiting
line model is formed and calculations such as waiting for service and service
time in the queue are made. </span> <span lang="en" style="font-size:12pt;line-height:150%;" xml:lang="en">Since
the service speed of all channels is considered to be equal in the wait line
models in the literature, it is not possible to determine to what extent each
service channel affects the total wait time </span> <span lang="tr" style="font-size:12pt;line-height:150%;" xml:lang="tr">.
In this study, a new approach was introduced to determine to what extent each
service channel affects the total waiting time on the waiting line. </span> <span style="font-size:12pt;line-height:150%;"> For this purpose, waiting time is calculated by
weighting the system units with the multi-criteria decision-making techniques.
The results obtained with the current queuing theory are compared with the
results obtained according to the new approach presented in the study. </span> <span lang="en" style="font-size:12pt;line-height:150%;" xml:lang="en">The results obtained in the study; the differentiation of the service speed
of service channels has led to more realistic results and it has been
determined which service channel has more effect on waiting times </span> <span lang="tr" style="font-size:12pt;line-height:150%;" xml:lang="tr">. </span> <span style="font-size:12pt;line-height:150%;">According to the results obtained with the new method, suggestions have been offered in
regard to which service channels should be prioritized in the improvement works
to be made for reducing the waiting time.  </span> <span lang="tr" style="font-size:12pt;line-height:150%;" xml:lang="tr"> </span> </p> <p> </p>}, number={3}, publisher={Ankara Hacı Bayram Veli University}
