Transportation routing with Vehicle Routing Management programs : Case study of Plastics Industry

Abstract

This research aims to 1. Study the method of arranging plastic pellet
transport routes of the case study companies, 2. Increase the efficiency of
transporting plastic pellets of the case study companies, which has a point for
sending plastic pellets along the route Bangkok – Chonburi - Samut Sakhon –
Ayutthaya. By collecting data on past plastic pellet transport, analyzing
transport routing data with the Vehicle Routing Management (VRM) program.
Currently, the case study company uses 1 pickup truck to transport plastic
pellets to customers in 13 locations, by relying on the experience of the
transportation department head in arranging transport routes together with the
use of location assistance systems (GPS) to determine the route at each
delivery point by the driver. Before the renovation, the average annual
transportation fuel cost was 1,802,864.40 baht per year, with an average
transportation distance of 180,286.44 kilometers per year. After applying
techniques for analyzing transportation routes with a transportation routing
modeling program, this makes it possible to reduce fuel costs by 642,640.80
baht per year, the average transportation distance is 116,022.36 kilometers per
year. and can reduce transportation distance by 64,264.08 kilometers per year.
