A Multidisciplinary, Expert-based Approach for the Identification of Lifetime Impacts in Asset Life Cycle Management

Everyday our lives are dependent on countless physical structures. These assets represent an enormous value for their owners and for society at large. To grasp the full potential of these assets, a deep and thorough understanding of an asset's complete lifetime is needed. Problems with data collection and data quality however limit currently available methods for Asset Life Cycle Management in their potential to deliver such a deep understanding. Therefore, this paper proposes to focus on the identification of lifetime impacts: trends or events that may have a positive or negative influence on the remaining lifetime of the asset. Timely identification of these impacts allows the asset owner to prepare appropriate measures. Based on a literature review and a case study, the paper argues that a multidisciplinary approach employing both quantitative and qualitative information is needed. The Lifetime Impact Identification Analysis (LIAA) method is presented, incorporating technical, economic, compliancy and commercial perspectives on the asset. The method exploits expert-sessions to gather and structure available knowledge into a Lifetime Impact Report. Preliminary test results show that the proposed method is promising to both theory and practice.
