Multi-model-based Access Control in Construction Projects
This work addresses access control and efficiency issues for virtual organizations in construction, but it appears incremental as it builds on existing multi-model container formats.
The paper tackles the problem of exchanging complex technical models in construction projects by developing a dynamic filtering approach that provides simplified views and appropriate permissions based on project context and organizational structure, resulting in reduced communication delays and tailored access for virtual organization members.
During the execution of large scale construction projects performed by Virtual Organizations (VO), relatively complex technical models have to be exchanged between the VO members. For linking the trade and transfer of these models, a so-called multi-model container format was developed. Considering the different skills and tasks of the involved partners, it is not necessary for them to know all the models in every technical detailing. Furthermore, the model size can lead to a delay in communication. In this paper an approach is presented for defining model cut-outs according to the current project context. Dynamic dependencies to the project context as well as static dependencies on the organizational structure are mapped in a context-sensitive rule. As a result, an approach for dynamic filtering of multi-models is obtained which ensures, together with a filtering service, that the involved VO members get a simplified view of complex multi-models as well as sufficient permissions depending on their tasks.
