Reliability Analysis of a Multi-State Truly-Threshold System Using a Multi-Valued Karnaugh Map
share
This paper deals with the Boolean-based analysis of a prominent class of non-repairable coherent multistate systems with independent nonidentical multistate components. This class of systems is represented by a multistate coherent truly threshold system of several states, which is not necessarily binary-imaged. The paper represents such a system via Boolean expressions of system success or system failure at each non-zero level, which are in the form of minimal sop formulas, or disjoint sop formulas. These are expressions that are directly convertible to expected values. Several map representations are also offered, including a single multi-value Karnaugh map.
