If the numbers are really small:

Z = SUM Bz[j, k]*max(j, k)

X = SUM Bz[j, k]*j

Y = SUM Bz[j, k]*k

I'd forgotten to add
1 = SUM Bz[j, k]

I think that this is *linearly* equivalent to the preceeding,
but it has a lot more binaries, so I can't recommend it.
Rather obviously (X, Y, Z) is constrained
to the convex hull of its feasible values.
