Sequential diagnosis tool

This paper deals with the sequential diagnosis approach and the associated test sequencing problem (i.e. the problem of generating the sequence of tes ts required to reach a diagnostic conclusion at minimum cost). The traditio nal test sequencing problem is generalized here to include asymmetrical aci d multi-valued tests. We present the sequential diagnosis tool (SDT) that e nables the user to generate solutions of the generalized test sequencing pr oblem. SDT can be employed as a kernel of a diagnostic reasoner in automati c test equipment or system maintenance software. (C) 2000 Elsevier Science B.V. All rights reserved.
