ABSTRACT
/Full article available only in Bulgarian language/

Feeding of flotation factory with material of constant concentration leads to increasing of
extract ratio and sparing flotation reagents. In the article the task of optimal concentration is
solved accordingly to composite target function, including subcriterias for equal, maximal and
proportional load of excavators and criteria for maximal flow of ore. The function includes
priorities of excavators, entered by dispatcher. Optimum of the function is located using method
of multipliers of Lagrange.
Method is realized in dispatch system for monitoring and control in real time
off-highway trucks. Position of trucks are monitored via GPS NavStar. Data are transmitted
bidirectionally from/to controlling computer via UHF channel. Except flotation, the system
controls all the transport process, queues to excavators, measures the length of routes and other
parameters.
