This paper proposes a real-time decision support tool based on the rolling-horizon principle that manages staff activities (relocations and maintenance) of a one-way carsharing system and considers carpooling the staff in the relocated carsharing vehicles for extra cost reduction. The decision support tool is composed of three elements: a...

Infrastructure maintenance is a complex task due to operational needs of service quality, availability demands, traffic intensity, and budget constraints. Traditionally, maintenance decisions are based on infrastructure managers' experiences, judgments, and available choices. Though, the technology push and the availability of an abundance of...

Built heritage contains value on many scales. On the most basic level it represents the investment of building materials following a constructional logic. As the use of once-predominant materials goes out of fashion due to changing technological regimes and architectural styles, knowledge about them is lost. Yet retaining and maintaining their...

Presently, maintenance management of assets in infrastructure utilities such as electricity, gas and water are widely undergoing changes towards new working environments. These are mainly driven against the background of stringent regulatory regimes, an ageing asset base, increased customer demands and constrained financial resources. Therefore,...

Functional criteria have been mostly defined in urban pavements using subjective methods, rather than by means of objective and repeatable procedures. The Whole<br/>Body Vibration, the Heart Rate Variability, and new technologies to determine the<br/>IRI (International Roughness Index), are nowadays available. For that, an analysis of<br/...

Owners are responsible to maintain their own dwellings in an adequate manner. In practice however all kinds of constraints occur. Lack of financial means and insufficient (technical or practical) knowledge are the most important barriers. Because the quality of owner-occupied housing exceeds the individual interest; there are also general...

The electrical power sector is stimulated to evolve under the pressures of the energy transition, the deregulation of electricity markets and the introduction of intelligent grids. In general, engineers believe that technologies such as monitoring, control and diagnostic devices, can realize this evolvement smoothly. Unfortunately, the...

The financial crisis and the introduction of low-budget companies have brought major changes to the air freight community. Competition became stronger and cost control became more important. This led to new ways of organizing aircraft Maintenance, Repair, Overhauls and Upgrades (MRO&U), which became performance oriented. For the triad of...

This paper presents an automatic method for detecting railway surface defects called “squats” using axle box acceleration (ABA) measurements on trains. The method is based on a series of research results from our group in the field of railway engineering that includes numerical simulations, the design of the ABA prototype, real-life...

Asset managers of civil infrastructure are increasingly outsourcing their maintenance. Whereas maintenance is a cyclic process, decisions to outsource decisions are often project-based, and confusing the discussion on the degree of outsourcing. This paper presents a six-stage model that facilitates the top-down discussion for analysing the...

The infrastructure in the Netherlands is crucial for economic development on a national scale. Dramatic increases of transport and mobility accelerate ageing of infrastructure. The GNP of the Netherlands is strongly related to transport and to the two main ports (Port of Rotterdam and Amsterdam Airport Schiphol). The Netherlands is used to a...

Home-owners are in principal responsible for maintaining the physical quality of their dwellings. It is in their own interest to do this in an adequate manner, but all kinds of constraints can and do occur in practice. Lack of financial means and insufficient (technical or practical) knowledge are only two of the possible barriers. The quality...

To date, the focus in the field of sustainable building has been on new building design. However, existing residential buildings inflict great environmental burden through three causes: continuous energy consumption, regular building maintenance and replacements. This publication analyses and compares these three causes of environmental burden...

Unavailability of technical systems, such as aircraft, is expensive. Technical systems require maintenance to prevent and to remedy defects that cause unavailability. Users of technical systems usually bear the consequences of the risk of unavailability, in particular the loss of productivity. This is based on the presumption that users are best...

New procurement approaches combined with performance-based building approaches should reduce costs, but empirical qualitative and quantitative studies are lacking. Performance-based maintenance contracts give maintenance suppliers incentives to improve their way of working. Innovative, cost-effective solutions that meet the performance criteria...

This report presents an inquiry into cases of pavement design, construction and maintenance in which distress has been observed instigated by deeper subgrade or by inadequate attention for the interaction between subgrade and pavement structure. Almost all cases are situated in areas with subgrade of poor to marginal bearing capacity. The cases...
