Kaon production cross sections in nucleon-nucleon, nucleon-{Delta}, and {Delta}-{Delta} interactions are studied in a boson exchange model. For the latter two interactions, the exchanged pion can be on-mass shell; only contributions due to a virtual pion are included via the Peierls method by taking into account the finite {Delta} width. With these cross sections and also those for pion-baryon interactions, subthreshold kaon production from heavy-ion collisions is studied in the relativistic transport model. {copyright} {ital 1998} {ital The American Physical Society}
