Abstract

To efficiently and safely plan, schedule and control its interventions in underground facilities which are subject to ionizing radiations, CERN is currently developing a collaborative Web-based system. A similar project for maintenance management is also under way. On top of presenting their key requirements, this paper shows how the implementation of DSM can enhance a so-called “Web 2.0” or collaborative dimension by bringing an intuitive and fair way of taking the dependencies between several activities into account. It is also discussed that the incoherencies brought in DSM by
collaborative use (e.g. regarding the different constraints and dependencies between tasks) can be addressed by fitting into the binary DSM some collaborative data collected using the dependencies
described in Allen’s interval algebra, or at least a subset of them.
