Zusammenfassung:	The disclosure provides a method and a computer program product for determining distribution of fracturing components in fracture clusters of a wellbore, and a fracturing controller. An example of the method includes: (1) modifying surface flow rates for pumping a fracturing component into the wellbore, (2) measuring surface pressures for the surface flow rates, and (3) determining flow rates for the fracture clusters employing the surface flow rates, the surface pressures, and a model representing flow distribution of the wellbore. An example fracturing controller includes (1) an interface configured to receive surface flow rates and corresponding surface pressures for pumping a fracturing component into a wellbore, wherein the surface flow rates are modified in a series of steps, and (2) a processor configured to determine flow rates for the fracture clusters employing the surface flow rates, the surface pressures, and a model representing flow distribution of the wellbore.
