This paper presents an overview of two maintenance techniques widely discussed in the
literature: time-based maintenance (TBM) and condition-based maintenance (CBM). The …

This article gives an overview of the literature on asset management for multi-unit systems
with an emphasis on two multi-asset categories: fleet (a system of homogeneous assets) …

The objective of infrastructure management is to provide optimal maintenance, rehabilitation
and replacement (MR&R) policies for a system of facilities over a planning horizon. While …

Replacing equipment is an important decision that nearly all entities must face, generally
motivated by rising operating and maintenance costs of current assets or the technological …

In pavement management systems, it is beneficial to consider the economies of scale
stemming from the synchronization of repairs conducted on neighboring sections within a …

This paper addresses both the modeling and the resolution of the replacement problem for a
population of machines. The main objective is the computation of a minimum cost …

A stochastic, time-dependent integer program with recursive functions is proposed for the
problem of assessing a rail-based freight transportation system's resilience to disaster …

We present a general repair model for a multi-state deteriorating system subject to major
and minor failures. The process is modeled as a semi-Markov decision process with the …

Transportation infrastructure life-cycle management deals with maintenance decision
making of transportation facilities such as pavement, bridges, and railways under budget …

Condition assessments and rating systems are frequently used by field engineers to assess
inland navigation assets and components. The goal of these assessments is to initiate …
