In recent years, The blooming economics excite a high demand
for international express services in Taiwan.
However, more and more international express carriers have
entered and compete with each other in Taiwan's international
express business.
In such a competitive environment, efficiency in customer
service is more and more importance.
Courier service is one of the important aspects in customer
service. The efficiency of courier service is closely related
to duty partitioning and dispatching strategy.
The arising issues make the problem more difficult than
traditional "VRP" in two points: 1.the service demand of
customers and 2.customer's location generated during the
service period.
This thesis is mainly foused on experiment analysis for courier
service by the way of simulation. The objective is to design a
strategy of duty partitioning and improve the efficiency of
courier service.
According to the simulation results, some conclusion can be
made. 1. The 「NN」dispatching rule is more efficient for heavy
service load, and 「NN-LWT-NN」dispatching rule is more
efficient for light service load.
2. If duty area is the shape of "rectangle" then the size of
duty area should be as small as possible. The courier service
is more efficient if the density of customers distributed is
heavier in the center over duty area.
3. If the customer is distributed in the shape of "two center
or uniform", then duty area must should be as square as
possible and the size should be as small as possible.
