SIMULATION
Background
- Increase of import and export freight is an important problem in the container transportation
- Most of Single-trip and Round-trip Transportations are separated to each transportation type and not change.
- Increasing the Transporting distance and time Increasing the Transportation cost and the number of necessary vehicle
SIMULATION
Objective
Modeling for existing transportation system by using Arena
Finding a new solution (route) for improving the present system
-> Analyzing the results of present system and improved system
Combination of Single-trip and round-trip transportation
Using the rail transportation
Improving the present transportation system
Minimizing total distance and total time minimizing the total cost
SIMULATION
Company Introduction
- Company : CHUNIL Cargo Transportation Co., Ltd.
- Major business: home-delivery service
CY operation
steel and bulk transportation
- The number of truck : 150 (in Busan)
- Object of study : Inland Container Transportation
- Contents of object
managing the transportation orders of customers
which is linkage between national city and
busan (depot)
SIMULATION
System Description
Collect data(Orders)
Assign theOrder
Single-trip Transportation
Round-trip Transportation
Rail Transportation
Finish
1. Assign new order to rail transportation “only if train is not occupied”2. Combine the coverage route (round + round , round + single, single +single)3. Return , if there is no satisfied route ( in the combination step )
Transport
Return
SIMULATION
Simulation Approach
Data-Transporting time and distance
-Requirement time
-Order type : delivery, pick-up
-Trip type : single (delivery, pick-up) , round (D + P , P + D)
-Destination ( 11 kinds of cities )
Assumption-The number of vehicles are infinite
-Container size :40 Ft ( each containers use only 1 truck )
-Container type : Dry container
-Every vehicle depart from busan and go back to busan
-Regard every CY and Port as just one station

Verification method of simulation
Verifying Data
= Total transportation cost
( Vehicle transportation cost + Rail transportation cost )
I. Vehicle Transportation cost (each vehicles)
I . Company’s charge (return) -
[Customer’s Fare (from busan to destination) + Company’s charge (return)]*10%
-> Driver’s profit
( Increasing the number of vehicles -> Increasing the cost )
II. Each fare is depends on the distance between cities
III. Each fare can be changed by “ Trip type “

Verification method of simulation (cont.)
From busan Kwang- yang Ok-chun Bu-gok
Distance 232 km 257 km 410 km
Fare (won) 674 674 674
Type rate (won) 674* 74% 674*74% 674*74%
-Rail Transportation I. There are 4 kinds of station ( busan, kwang-yang, ok-chun, bu-gok )
II. This charge depends on the “ trip type “-- Distance ( classified by each station ) * Type rate (empty container)-- Distance ( classified by each station ) * Fare (full container)
