Components from a heterogeneous population may result in non-well behaviour in the failure rate function. This paper considers a population of components that consists of two different sub-populations: a population of weak components and a population of strong components. This component heterogeneity is treated using a mixture distribution for the components' lifetimes. This mixture models two distinct behaviours: a short characteristic lifetime for the weak components and a long characteristic lifetime for the strong components. Simple policies may not be effective to address the distinct behaviours of failures for these components. Thus, combined preventive replacement and a burn-in procedure based on a multi-criteria perspective are proposed in order to suitably integrate the different objectives from the burn-in and preventive replacement procedures, taking into account the preferences of the decision-maker. We consider the cost and the mean residual life as the criteria of the proposed model. Multi-attribute Utility Theory (MAUT) allows alternatives that are more aligned with the preferences of the decision-maker to be developed.
