The Hunter Valley Coal Chain Coordinator (HVCCC) acts as a coordinating body servicing: coal producers; haulage providers; track owners; and terminal operators in the Hunter Valley region of New South Wales. The HVCCC coordinates the movement of millions of tonnes of coal annually through a highly complex supply chain ending at the Port of Newcastle, one of the largest on the East Coast of Australia.
The HVCCC Planning team must maximise the efficiency of the supply chain by objectively coordinating and synchronising the flow of coal from train load points through the track network and terminal infrastructure and onto vessels to fulfil customer orders as cost effectively as possible.
- The Hunter Valley Coal Chain is an incredibly complex supply chain consisting of: 12 producers; 45 coal mines; 4 haulage providers operating 13 separate fleets comprising 70 separate rail units; and 3 terminals, exporting to customers around the globe.
- In any two week period the coal chain can load around 75 separate vessels serviced by over 1000 separate rail journeys.
- There is an enormous number of interdependent decisions, that have to be made simultaneously, to ensure the overall system is operating efficiently including:
- Which cycles should each rail unit in each haulage provider fleet undertake in the planning horizon to rail the right coal for the right cargoes?
- How should stockpile space within terminals be allocated over time to store individually assembled cargoes or manage dedicated product stockpiles to ensure maximum velocity of material through the terminal given its available infrastructure?
- When should vessels load, noting they cannot load until all material has been railed and stacked and enough reclaiming and ship loading capacity is available?
Polymathian worked with HVCCC to revolutionise the way they optimised this highly complex coal chain by developing a world class rail supply chain optimisation tool - RACE.
- Produce optimised plans automatically in under 20 minutes
- Readily run and compare scenarios to answer questions commonly posed by the supply chain stakeholders they serve
- Easily investigate the impacts of changes to maintenance schedules, coal volumes, rolling stock availability and vessel arrivals
- Determine, with high fidelity, where constraints might be active in the supply chain at any time
