Planning Smelter Logistics: A Process Modeling Approach

A dynamic logistic model, based on High Level Petri Nets, was generated to aid the planning of potroom activities, potroom traffic and logistic equipment needed for a smelter expansion project. This model includes all relevant pot-tending operations, such as anode changing with cavity cleaning and covering, metal tapping, alumina feeding, beam raising, bath tapping, pot stoppage and start-up, gantry transfer and crane maintenance exchange.
