  We propose a novel technique for the combination of multi-jet merged
simulations in the five-flavor scheme with calculations for the production of
b-quark associated final states in the four-flavor scheme. We show the
equivalence of our algorithm to the FONLL method at the fixed-order and
logarithmic accuracy inherent to the matrix-element and parton-shower
simulation employed in the multi-jet merging. As a first application we discuss
Zbb production at the Large Hadron Collider.
