A new treatment of Bose-Einstein correlations is incorporated in a space-time parton-shower model for e{sup +}e{sup -} annihilation into hadrons. Two alternative algorithms are discussed, and we use a simple calculable model to demonstrate that they reproduce successfully the size of the hadron emission region. One of the algorithms is used to calculate two-pion correlations in e{sup +}e{sup -}{yields}Z{sup 0}{yields}hadrons and e{sup +}e{sup -}{yields}W{sup +}W{sup -}{yields}hadrons. Results are shown with and without resonance decays, for correlations along and transverse to the thrust jet axis in these two classes of events. (c) 2000 The American Physical Society.
