Proposal: Operations Research and Analytics
If the forum title were "Operations Research and Proposed Analytics" rather than "Operations Research and Analytics", it would be clearer that the forum is not about choosing the best shades or fonts for analytics dashboards and similar things often going under the Analytics moniker. Prescriptive analytics might be more or less synonymous with Operations Research. But analytics encompasses many things which would make the forum too diffuse.
Edit: As I stated in comments, I interpret "and" in the forum title to be union, not intersection. So everything in Operations Research is covered. Also, as elaborated in the comments, I view Operations Research widely, not as just being a bag of technical tools. Therefore it includes most of the "good" stuff often promoted under the Analytics banner, to address the end to end analysis process.
