An online panel from the PyMC Labs meetup: Luca Fiaschi of PyMC Labs and Ian Costley of Wegmans describe how the two teams co-designed a Bayesian model for deciding where to open new supermarkets. The model encodes operator expertise, uses real drive-time trade areas, forecasts in-store and e-commerce demand separately and measures cannibalization across the store network. The discussion covers why Wegmans built the capability in-house with a partner rather than buying a black box, and what owning and extending the model afterwards involves. A Q&A follows.
