Cross-asset management for road infrastructure networks

Abstract

Limitation of resources and variations of interest or priority of different stakeholders of road infrastructure networks often lead to multiple considerations of intervention options. It is of interest to identify the best available intervention or investment option under a multi-criteria framework. Markers of performance may be varied and the approach towards maintenance management may have different philosophies based on specific organisational structures of governance. This paper presents a methodology for cross-asset management that caters to different maintenance management systems without modification. Optimisation approaches and effective implementation methods are identified. Practical implementation guidelines of the developed framework are illustrated.

Development of a Cross-Asset Model for the Maintenance of Road and Water Pipe Assets using AHP Method

“…According to Deix et al [4], cross-asset management comprises high-quality information on asset inventory, the condition of such assets, management strategies, customer perceptions, and a definition of strategic targets. The topdown approach and bottom-up approach are the two methods used for cross-asset optimization [4][5][6]. In the bottom-up approach, resource allocation is influenced by the technical assessment of individual groups of assets at the object level, whereas resource allocation in the top-down approach is based on a central decision that deals with infrastructure at the network level.…”
