“…A seminal introduction on VoI analysis is provided by the book of Raiffa and Schlaifer [14], while applications to management of structural and infrastructure systems is provided by Pozzi and Der Kiureghian [15], Straub [16], Zonta et al [17], and Malings and Pozzi [18]; most applications refer to a single-decision making problem, however assessment of the VoI in sequential decision making is also presented in [16,19,20]. While metrics for inspection scheduling applied to IM have been developed for general applications [19,21], we recently proposed a VoI-based approximate heuristic for system-level inspection scheduling for POMDPs [22]. Also recently, Srinivasan and Parlikad [23] investigated how to evaluate VoI in POMDPs.…”

“…POMDP has previously been applied to planning of inspections in deteriorating structure and infrastructure (e.g. Madanat 1993;Corotis et al 2005;Papakonstantinou and Shinozuka 2014;Memarzadeh and Pozzi 2016). A special case of this model arises when the demand at any time can be observed with certainty.…”

Demands on structures and infrastructures change over their service life and cannot be predicted with certainty. Adaptable (or flexible) infrastructure designs are thus potentially beneficial, enabling easier adjustments of the systems at a later stage. However, systematic quantitative investigations and corresponding recommendations are missing. In (Špačková and Straub 2016), we present a framework for such an analysis, which is based on sequential decision processes. In this contribution, we summarize the approach and focus on the interpretation of flexibility. We show that the framework enables quantification of the value of flexibility, to answer the question: what is the maximum amount that should be spent additionally to ensure system flexibility? Two case studies illustrate that this value is strongly dependent on a number of factors, in particular on the types of uncertainty present and the amount of future information collected in the future.

“…POMDPs may further be extended to tackle problems of multiple components or systems, as exemplified in Memarzadeh & Pozzi (2016). The provided example on a farm of 25 wind turbine components reveals the importance of availability of observations from these components, in the form of inspections, for cost-effective management of the farm.…”

Abstract. The aim of this review paper is to summarize available options for decision-support toward the optimal management of infrastructure systems under consideration of uncertainties. Thereafter, we elaborate on a particular variant, namely Partially Observable Markov Decision Processes (POMDP), as a flexible framework for the incorporation of information from observations (visual inspections, non-destructive testing and monitoring) in the context of optimal inspection and maintenance planning. Examples from the literature are presented, demonstrating the potential of planning under uncertainty and the links to the Value of Information (VoI) from Structural Health Monitoring (SHM).
