Papadimitriou, "Multiobjective simultaneous stowage and load planning for a container ship with container rehandle
in yard stacks," European Journal of Operational Research, vol.
They show mine planners which designs prove most effective, with the least rehandle
. They give managers an idea about areas of their mine that need extra attention.
Thiess is contracted to remove a further 85 million cubic metres of overburden and mine approximately 16 million tonnes of coal and eight million tonnes of rehandle
during the current contract term.
A distribution-center bypass program can greatly reduce the per-unit cost of goods by eliminating the need to rehandle
product in the importer's distribution center.
(waste being dumped back on to benches to build a smooth floor) has been reduced by two-thirds
Once material is loaded into a truck, there is no reason to have any rehandle
. Over the last two years, we have sold 40 dozers [D11s and 475s] and replaced them with loading equipment."
By doing it accurately the first time it is quicker, because there is no rehandle
"Over the past three years, customers who have adopted the new 3-D machine control technology have realized significant benefits, which include productivity enhancements of up to 30%, reduced rehandle
, and the virtual elimination of certain steps, such as staking."
statistics can be accumulated on each block movement, enabling material to be tracked and monitored through each step of the mining process.
Lowered rehandle--Without installing the XPS, expectations of dragline rehandle
for the late '80s were in excess of 50%.
In the past, rehandle
had been avoided by operating diligence and good, but potentially costly, survey support.
It will also rehandle
stockpiled material as required.
