Learning Contextual-Variability Models

Paul Temple, Mathieu Acher, Jean-Marc Jezequel, Olivier Barais
2017 IEEE Software  
Modeling how contextual factors relate to the configuration space of a software system is most of the time a manual and error-prone task, highly dependent on expert knowledge.  ...  As a result, software developers and product managers can automatically extract the rules that specialize highly-configurable systems for operating on specific contexts.  ...  It can be tuned for internally influencing the results of subsequent computations.  ...

Optimal Configuration in Production Planning and Control

Christoph Wolfsgruber, Gerald Lichtenegger
2016 Berg- und Huttenmännische Monatshefte (BHM)  
Based on these fundamental insights, a framework for an optimal configuration in production planning and control is presented.  ...  The decision on the optimal PPC configuration should be based on the overall system costs for the information system, the PPC system, the resulting system performance and the costs for the indirect factors  ...  Despite the best practices in PPC configuration, standard measures using lean tools and complexity management approaches have to be taken to gain control over these highly influencing factors.  ...
