    Abstract
    </h2>
    <p>
    Software Product Lines modeling improves software development processes by automating
    system debugging and analysis. The objective of this paper focuses on extending the
    formal framework SPLA to represent features such as cost objects and comparisons
    between products in terms of production costs. We illustrate this extension with a practical
    example by modeling the creation of valid run-lists for Chef, a widely used configuration
    management tool. Also, we execute our formal specification in a distributed system using
    SCOOP and we provide strategies to optimize the effort required to compute a SPLA term.
