Abstract
Two new methods for the construction of partially balanced incomplete block designs with two associate classes are reported. The first method concerns triangular designs and the second one cyclic designs. Some designs are obtained which have not previously been published. Furthermore, the first results of a systematic search of cyclic designs using a digital computer are illustrated.
Riassunto
Si illustrano due nuovi procedimenti di costruzione di piani di esperimenti incompleti a due classi: il primo riguarda i piani triangolari, il secondo i piani ciclici. Si ottengono così piani, alcuni dei quali non figurano negli elenchi fin'ora pubblicati. Si espongono inoltre i primi risultati di una ricerca sistematica, compiuta con un programma di calcolo per un elaboratore elettronico, di piani ciclici a due classi.
