DE ROMERO, Matilde E et al. Designing a computarized mathematical model corrosion costs . Rev. Téc. Ing. Univ. Zulia [online]. 2005, vol.28, n.1, pp.28-41. ISSN 0254-0770.

Recording and analyzing the costs associated with corrosion control in Venezuelan Industry, indeed in most industries, is not considered as a factor associated with an individual or independent heading under Corrosion. They are simply listed or included under general maintenance operations, which conceals the costs really incurred by corrosion. The need therefore arises for segregating these costs so as to be able to determine not only how much industry invests with respect to this problem but also how it impacts its budgets and the losses sustained as a function of the Gross Domestic Product (GDP). These costs were determined by first developing a phase in which a series of surveys and interviews were carried out among the industries that are most important for the Venezuelan economy, considering two of the main categories in the Industrial Sector: Production-Manufacture and Services. Secondly, a computerized mathematical model was developed from the series of variables produced by these instruments. The model includes all the essential variables associated with corrosion problems and control methods. The application of this model will provide knowledge of the costs associated with the problem of corrosion in Venezuela at large as well as in the industries in which it is applied.
