1st Business Case: Decision Support Systems for Asset Management
@aszapla
![Page 13: Big Data: Business Case in Alicante](https://reader031.vdocuments.net/reader031/viewer/2022030316/587468851a28abab198b74f5/html5/thumbnails/13.jpg)
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
