Center node: "compositionality for quantitative specifications"
  Abstract: We provide a framework for compositional and iterative design and verification of systems with quantitative information, such as rewards, time or energy. It is based on disjunctive modal transition systems where we allow actions to bear various types of quantitative information. Throughout the design process the actions can be further refined and the information made more precise. We show how to compute the results of standard operations on the systems, including the quotient (residual), which has not been previously considered for quantitative non-deterministic systems. Our quantitative framework has close connections to the modal nu-calculus and is compositional with respect to general notions of distances between systems and the standard operations.

Connected through hyperedge HE-1 (induced by source paper "computing branching distances using quantitative games"):
  with members:
    - "a linear time branching time spectrum of behavioral specification theories"
    - "a robust specification theory for modal event clock automata"
