From sewer inspection programmes to rehabilitation needs: research and results related to data quality and availability with the support of numerical experiment

摘要: The purpose of this paper is to discuss the influence data availability and quality within a utility prioritise inspection rehabilitation needs. Data are required in order predict structural condition assets. Lack budget limitation do not encourage utilities evolve from reactive proactive management. Methods tools exist; however, improving operational practices will require demonstration collection benefits. In article, asset management approaches presented discussed regarding data; closed-circuit television reports elaboration prioritisation Bottlenecks related uncertainty, imprecision incompleteness identified, authors propose study these questions. This article also highlights use numerical experiment simulate scenarios, methods or demonstrate interest new practices. Numerical allows constr...
