Team planning under an electricity failure for a GSM operator
Abstract
Base
stations are very important for all GSM operators. Efficient base stations
prevent income loss while bringing prestige to the company. This study deals
with the problem of transportation planning of portable generators during
electricity failure for a leading Turkish GSM operator. There are often
electricity failures in a particular area of Mersin which cause not only
customer complaints but also income loss for the company. After an electricity
failure, a battery steps in for that station. However, the lifetime of battery
is limited and sometimes not enough during the failure. In that case, a fixed
generator could step in to give service properly. Unfortunately, because of the
high cost of fixed generators, not all base stations have a fixed generator.
Therefore, the company tries to interfere this problem by using limited number
of portable generators. Field operation teams transport and set up these
portable generators to the sites with electricity failure before the battery
dies. The problem is to schedule the transportation of portable generators to
the base stations with electricity failure. In this study, composite
dispatching rule, one of the scheduling algorithms, is used to solve this
planning problem effectively. An Excel based decision support system has been
developed for field operation team. Whenever a failure occurs, after inputting
necessary information to the Excel, transportation schedule for each team could
be easily obtained by the company experts.
