Fuel Network Optimizer is a next-generation, AI-enabled software product for the oil and gas industry. It takes massive amounts of individual retail and wholesale fuel transactions as inputs, cleans them, and quickly computes a suite of business intelligence metrics (like volumes, profits, prices, etc.). It then combines these internal metrics with external factors such as weather, demographics, population density, traffic, proximity to major attractions, seasonality, and holiday effects, as well as features about each specific client retail site (like physical characteristics and customer loyalty), into machine learning models. The models predict sales, profits, etc. on a forward-looking basis, and also decompose history to increase understanding of what has transpired. Elaborate modeling of competitor behavior also exists, with a sophisticated price elasticity model that anticipates competitor reaction and recursively propagates price changes throughout the entire network of sites.
