A single-dependent agent approach for stochastic time-dependent truck dispatching in open-pit mining

摘要: Material transportation is one of the most important aspects open-pit mine operations. The problem usually involves a truck dispatching system in which decisions on assignments and destinations are taken real-time. Due to its significance, several decision systems for material mining have been developed last few years, improving productivity reducing operational costs. This paper presents single-dependent agent approach based Time-dependent Markov Decision Processes (TiMDPs) model an example mine. uncertainty present as stochastic path selections by driver. Simulations executed using SimEvents™framework, results compared other heuristics commonly used industry show superiority proposed approach.
