Technical report: evaluation of the relative efficiency of gas stations by data envelopment analysis / Nor Amidatul Nadia Bakeri, Noor Shahiera Ruslan and Noor Aimi Asyikin Mohamad Zaini

This research study is conducted on evaluating the relative efficiency of 36 gas stations in Kedah. In this project, the efficiency was determined by using Data Envelopment Analysis (DEA) which transforming multiple inputs into multiple outputs. Based on the result we get, it shows that there are only four efficient gas station with efficiency score of 1 (GS 1, GS 2, GS 6, and GS 28), whereas another 32 gas stations are not efficient with the efficiency score in range between 0.0398 to 0.8884. So, the efficient gas stations will become the benchmark or the reference set to the inefficient gas stations in order to improve their efficiency using project determination. This means that, management should minimize the inputs so that it could be balanced with the outputs production in order to improve or increase the gas station's efficiency.
