@aszapla
Why Decision Support for Asset Management?
Investment Decision Support Systems have become a
priority issue for the water business
Does really Asset Management require a DSS?
High number of invisible assets
High maintenance costs: need to optimize the
investments
Increasing risk of failure (hydraulic, structural,
environmental) due to ageing
Need to keep the service level
Account for necessary resources
@aszapla
