Keywords:
Transportation Management System, Improving Efficiency, Transportation SoftwareAbstract
According to Thailand's policy under the direction of General Prayut Chan-o-cha, Prime Minister, who came to the country on the vision of "Thailand 4.0" Transportation technology is another important aspect in the development of the transportation system and the economic system of Thailand. This research has applied the logistic management software technology the Vehicle Routing Program (VHP) in conjunction with the GPS system to perform and compare performance.
Performance efficiency of transport of the case study has increased in all 3 dimensions as the following: 1) The Dimension of Cost Management has reduced costs 543,443.64 Baht / year; 2) The Dimension of Time (Lead Time), the company does not have to pay overtime. After improving, drivers have returned to the company around 14.00 P.M. As a result, companies can use the remaining time before time out in meetings, training employees or provide other support staff within the company; and 3) The Dimension of Reliability, before the company has updated the product does not deliver correctly in average of 2 orders per day (5.88%), Improvement resulted in 3 months improvement period no errors or be 100% reliable.
