An evidence-based approach for value for money assessment of Roading Infrastructure in New Zealand. Harish Shivaramu, Auxilium Ltd

  The Activity Management Plans (AMPs) are developed by the Road Controlling Authorities (RCAs) to outline their short-term and long-term management approach for the maintenance and operation of the road network under their jurisdiction. Ideally, these AMPs need to be customer and outcome focused, and should also be able to demonstrate ‘sound principles and processes’ […]

Unblocking the flow of data. Danny Fitzgerald, Fulton Hogan

  Organisations who are strongly focused on data-driven decision making have four per cent higher productivity overall, and six per cent higher profits, according to the Harvard Business Review.  Data-driven, or evidence based, decision making relies on the provision of timely, accurate, useful information, however many organisations still struggle to facilitate the healthy management practices […]

A simplified approach to forward works plan modelling to address deterioration rate uncertainty. Ted James

  Deterministic, network level forward works plan modelling provides an analysis simplification relative to  probabilistic modelling.  But the unexplained performance variability issue is important both  for  pavement maintenance practitioner and for budget management.  Obviously  addressing variability might introduce an increase in computer run time, a significant issue for large networks analysis. It is argued that […]

The use of genetic algorithms in Road Maintenance Optimisation. Fritz Jooste, Lonrix

The solution to the problem of finding an optimal set of road maintenance strategies under a multi-year budget constraint is exceedingly complex. Over the past few decades many different approaches to this problem have been implemented – these include linear programming, dynamic programming and – more recently – genetic algorithms. The latter type of model […]
