Recently, the port logistics market is rapidly expanding,
along with the active maritime trade. To adjust to
this trend and gain a competitive advantage, competition
among shipping companies at home and abroad has intensified,
and many efforts are being made for the improvement
of customer services and cost saving. In particular, car carriers
transporting more than 80% of total car import/export
volume must quickly make efforts to reduce transportation
costs. Much research has been conducted to improve the efficiency
of maritime transportation, but studies on car carriers,
which are given relatively less importance, have been
lacking.
