For us, the NN is used in a grey box model for MPC in chemical engineering. The factories we control have relatively long characteristic time, together with all the engineering bounds, we can use the NN to model parts of the equipment from raw DCS data. The NN modeled parts are usually not the most critical (we are 1st principles based for them) but this allows us to quickly fit/deploy a new MPC in production. Faster time to market/production is for us the main reason/advantage of the approach.
