ABSTRACT
This article discusses the use of an Economic End of Life Indicator (EELI) in the context of network management. Objects within a network are subject to technical aging, which reduces their performance. Over time, these objects, as well as the networks in which they are located, also undergo functional aging. This article presents a vision in which asset management scenarios are categorized into preserving, upgrading, downgrading, and mitigating. An EELI is a financial indicator that can be used to justify choices between maintaining and renewing within the preservation process. However, an EELI can also be used as an indicator for strategic investment by determining where upgrading and renewing are cost-effective to combine. The EELI is generated at the object level but can be displayed on a network map alongside other indicators that reflect the functional and technical condition of (parts of) the network. This enables more integrated and targeted investment decisions. This paper is written in the context of Rijkswaterstaat. Within Rijkswaterstaat’s network, many objects will reach the end of their technical lifespan in the coming decades, leading to a significant wave of investments. Adequate supporting data, presented in an insightful manner, is required to make these investment decisions.
