Contribution of the three-dimensional model to the reliability allocation of multiphase systems

The purpose of this paper is to deal with the allocation requirements of the dependability of the multiphase systems.

It consists of a proposal for a combined methodology based on the simultaneous use of decomposition systems and reliability allocation method.

In the developed methodology, the authors use the principles of risk assessment and propose a new formulation of weight allowance with reference to the structural‒functional dependence.

The suggested methodology provides invaluable help to implementation process analysis.

The adopted allocation approach is based on the use of a three-dimensional model: temporal, structural and functional decomposition of systems.
