The
queueing theory has been used by academicians and practitioners to solve supply
chain problems over the years. Here, we propose a system dynamics approach and
queuing theory parameters to discover the best method to handle the (supply
chain) “Waiters” problem via a telecommunication service provider. We developed
more than one system dynamics model and introduced the following parameters:
the number of times information about registered waiters and the number of days
required for procuring and commissioning the
(telecommunication) ports are collected in a month. We found the number of waiting times for the customers is reduced and
improved when the above-mentioned first parameter is performed more frequently
(i.e.,more than
once).
