Il recente sviluppo delle tecnologie informatiche ha consentito agli istituti di valutazione di migliorare il processo di assemblaggio dei test tramite l’automated test assembly (ATA). Una struttura generale per ATA consiste nell’adottare modelli di programmazione intera-mista. Questi modelli sono pensati per essere risolti dasolver commerciali che, nonostante il loro successo nella gestione della maggiorparte dei problemi noti, non sono sempre in grado di risolvere problemi di ATA molto vincolati o di grandi dimensioni. Inoltre, tutti i parametri sono considerati fissi e noti, un’ipotesi che non vale per le stime dei parametri di item response theory (IRT). In questo lavoro proponiamo un modello chance-constrained per affrontarel’incertezz...
