project about operation research
Koray has dealt with my project professionally, and he knew what I wanted from him since the beginning. He was clear on defining the OR models and how are they necessary and related to the problem. He was open for comments and provided clear explanations for any concern I had. I would definitely hire him again if I had a problem regarding OR.
