Abstract

Life Cycle Cost Analysis (LCCA) is a methodology developed to

evaluate the variation in the costs of assets during their useful life.

This paper explores aspects related to the impact of reliability on

total life cycle costs and describes the basic model of constant

failure rate (Woodward’s model). This model includes within its

evaluation process, the estimation of the consequences (low

reliability costs) that could be caused by the various failure events

of an asset within a production system. The research considers the

presentation of a case study for the application of the Woodward’s

model in the selection and replacement of a compression system

in an oil and gas industry company, which allows contrasting the

performance of a traditional system versus a system based on

technology and tools of industry 4.0, analyzing in a real case the

strengths, limitations, realities, and myths of the application of this

type of technology in the case under study. As a final point, this

work concludes by presenting some recommendations aimed at

consolidating the LCCA methodology within a process of Asset

Management.
