RT Book, Section T1 On the expressiveness of refinement settings A1 Fecher, Harald A1 Frutos Escrig, David De A1 Lüttgen, Gerald A1 Schmidt, Heiko A2 Arbab, Fahrad A2 Marjan, Sirjani AB Embedded-systems designers often use transition system-based notations for specifying, with respect to some refinement preorder, sets of deterministic implementations. This paper compares popular such refinement settings — ranging from transition systems equipped with failure-pair inclusion to disjunctive modal transition systems — regarding the sets of implementations they are able to express. The paper’s main result is an expressiveness hierarchy, as well as language-preserving transformations between various settings. In addition to system designers, the main beneficiaries of this work are tool builders who wish to reuse refinement checkers or model checkers across different settings.
