Abstract

The problem of diagnosability of a system with three-valued test outcomes was considered in earlier works [l]-[3]. However all these works assume the system to be modeled as in [4]. In this correspondence, we consider a more general model of the system and study the diagnos-ability criteria in presence of three-valued test outcomes. In this model, each unit is tested jointly by a number of other units of the system as opposed to each test being carried out by a single unit of the system as in [4]. Necessary and sufficient conditions for the diagnosability of a system under this general model have been presented in this correspondence. Throughout the correspondence, diagnosability without repair has been considered.
