What is Truck Dispatching and Fleet Management?
Truck Dispatching and Fleet Management optimizes haul truck assignments in mining operations using real-time algorithms to minimize cycle times, fuel consumption, and operating costs amid stochastic demands and equipment failures.
This subtopic applies dispatch policies for shovel-truck matching and heterogeneous fleets in surface and underground mines. Key methods include simulation-based optimization and reinforcement learning for dynamic scheduling. Over 20 papers from 1993-2021 address these systems, with top-cited works exceeding 130 citations.
Why It Matters
Efficient dispatching cuts haulage costs, which comprise 50% of open-pit mining expenses, by reducing idle times and improving match factors (Chaowasakoo et al., 2017, 58 citations). Real-world applications include 5G-based unmanned vehicle scheduling in open-pit mines (Zhang et al., 2020, 64 citations) and Bluetooth beacon systems for underground transport time measurement (Jung and Choi, 2016, 132 citations). Stochastic optimization integrates production scheduling with fleet management to handle uncertainty (Both and Dimitrakopoulos, 2020, 53 citations; de Carvalho and Dimitrakopoulos, 2021, 46 citations).
Key Research Challenges
Stochastic Demand Handling
Dispatch policies must adapt to variable ore production and equipment breakdowns in real-time. Moradi Afrapoli et al. (2019, 85 citations) use multiple objective transportation problems for dynamic dispatching. Reinforcement learning addresses uncertainty in truck assignments (de Carvalho and Dimitrakopoulos, 2021, 46 citations).
Heterogeneous Fleet Matching
Mixed truck capacities complicate shovel-truck pairing and route optimization. Chaowasakoo et al. (2017, 58 citations) quantify benefits of heterogeneous match factors. Krzyzanowska (2007, 28 citations) analyzes impacts on operations at Venetia mine.
Real-Time Location Tracking
Underground navigation requires precise tracking for haulage efficiency. Jung and Choi (2016, 132 citations) deploy Bluetooth beacons for transport time measurement. Baek et al. (2017, 46 citations) develop BBUNS for optimal road selection.
