L.A.M. Technique: Systematic Generation of Logical Structures in Systems Reliability Studies

  • Giuseppe Reina
  • Giuseppe Squellati

Summary

A new approach for the reliability analysis of coherent and non-coherent systems is presented with regard to the problem of the systematic generation of failure logical structures. In particular, this methodology allows us to derive the logical behaviour of the system by means of the physical behaviour of its components.

To this end, suitable component failure-dependent analytical models are constructed to describe the component behaviour under normal and failure conditions. These models constitute, in their whole, a set of parametric equations describing the normal and failure behaviour of the whole system.

Starting from the considered component failure events, all the possible configurations of the system hypothetical failure structures are automatically generated in a controlled way. Now, by definition, to each given logical structure it corresponds a specific set of equations. Thus, the comparison of the corresponding numerical solution with analytically defined critical TOP conditions allows TOP and/or NON-TOP sets of events to be identified.

An application to the study of a simplified mixing circuit of an ethylene oxide production plant is presented.
