Simulation approach for practical testing improvement of logistics professional qualification system level 1 in Thailand

摘要

A practical testing level 1 of the road freight operator in Thailand's logistics professional qualification system has three stations: receiving, placement, and delivery. The number of examinees and the capability of officers in each station affect the complete number of examinees in limited time and average cost per examinee. In this article, the Markov chains model is used to describe the testing system on Arena simulation software. It shows that in Alternative#4 with four officers in three stations, one officer can service two examinees at the same time. It is suitable to install this alternative on the system because it provides the best result of a maximum number of complete examinees and minimum cost per examinee, with 63 examinees and 63.49 THB per examinee, respectively.
