| Popis: | PHM Atlântico was recently acquired by the Brazilian Navy. The size of the ship indicates that its operating and support costs must be the highest among the conventional vessels of the Force. In general, naval assets remain in active service for 25 to 30 years, although the Navy is extending the working time of some of its main vessels. Knowing the life-cycle costs of ships allows the Force to carry out the appropriate budget planning in the medium and long term. However, the new ships acquired, from construction projects or even directly from the market, lack historical cost records. This makes it difficult to estimate life-cycle costs. This paper aims to apply analogy and parametric methods, associated with Bayesian inference models, to estimate the operation and support costs for the PHM Atlântico. Only open source data was used in the research. The results by different methods were similar, offering interesting alternatives for the calculation of life-cycle costs in a situation of data scarcity. |
