Hybrid method of Data Envelopment Analysis with Supervised Learning

I look forward for any suggestions from anyone, related to my paper about convenience store performance measurement. Background Problems: Convenience stores have recently been a trend place of daily necessities shopping for Indonesians. This condition boost the growth of convenience store's numbers and encourage the management to improve its performance in order to face tight business competition, while the performance of convenience stores is actually determined by the efficiency of various product categories. In relation to this, the concept of benchmarking through Data Envelopment Analysis (DEA) is one of the well-known method used to measure company's efficiency that can be utilized to measure firm performance. However, DEA has limitation in handling large amounts of data, but supervised learning technique can be used as an alternative method to overcome it.
