Reinventing GTE with information technology

B. Brandau, T. Confrey, A. D'Silva, C.J. Matheus, R. Weihmayer
1999 Computer  
In response to shifting business demands, evolving information technologies play a key role in first reengineering and then reinventing GTE.  ...  GTE took a two-pronged approach in its response to this mandate. First, we developed a secure software solution that handles those CLEC requests that can be automated.  ...  In response to these challenges, telecommunications companies must take a new approach to conducting business.  ...

BN Applications in Operational Risk Analysis: Scope, Limitations and Methodological Requirements [chapter]

Paolo Trucco, Maria Chiara
2012 Bayesian Networks  
There are many uncertainties in development processes for products of processes like the uncertainties in estimating project completion time, the project needs for supply the quality of the output etc.  ...  Trucco et al. (2008b) applied the proposed methodology to identify and analyse the effectiveness of different organizational and behaviour-based measures for improving occupational safety in a leading  ...  Third, because the model has both causal and probabilistic semantics, it is an ideal representation for combining prior knowledge (which often comes in a causal form) and data.  ...

A rationale-based architecture model for design traceability and reasoning

Antony Tang, Yan Jin, Jun Han
2007 Journal of Systems and Software  
Large systems often have a long life-span and their system and software architecture design comprise many intricately related elements.  ...  Research into design rationale in the past has focused on argumentation-based design deliberations. Argumentation-based design rationale models provide an explicit representation of design rationale.  ...  This feedback loop could improve the decision making process and identify areas where design estimations are inferior.  ...

Towards a Comprehensive Framework for Climate Change Multi-Risk Assessment in the Mining Industry

Mavrommatis, Damigos, Mirasgedis
2019 Infrastructures  
The framework estimates the climate change risks in economic terms by modeling the main activities that a mining company performs, in a probabilistic model, using Bayes' theorem.  ...  In this study, a comprehensive framework is proposed for climate change multi-risk assessment at the local level customized for the needs of the mining industry.  ...  Finally, a future improvement of the model is the development of a web-based decision support system.  ...
