The parton branching equation is solved numerically by the O(4) Runge-Kutta method with a kinematical bound for the maximum number of partons. Using a simple hadronization model, the total-charged-multiplicity distributions of {ital e}{sup +}{ital e}{sup {minus}} annihilation and {ital p{bar p}} collision are explained. In the case of {ital e}{sup +}{ital e}{sup {minus}} annihilation, it is found that a kinematical bound for the maximum number of partons plays an essential role in making a multiplicity distribution narrow.
