Conformance Checking of Real-Time Models
Pages 15 - 32
Abstract
We compare conformance checking based on symbolic execution to conformance checking via bounded model checking. The application context is fault-based test case generation, focusing on real-time faults. The existing bounded model checking approach is performed on timed automata. It supports time-relevant mutation operators and a preprocessing functionality for removing silent transitions and non-determinism. The new symbolic execution approach is performed on timed action systems, which are a novel variant of Back's action systems augmented by clock variables and real-time semantics. It supports the same set of mutation operators, silent transitions, non-determinism and data variables. We show how to encode timed automata as timed action systems and perform experiments on three variants of a car alarm system, to investigate the influence of silent transitions, non-determinism and data variables. Both approaches rely on the SMT solver Z3.

Checking conformance for time-constrained scenario-based specifications
We consider the problem of model checking message-passing systems with real-time requirements. As behavioral specifications, we use message sequence charts (MSCs) annotated with timing constraints. Our system model is a network of communicating finite ...
Data-aware conformance checking with SMT
AbstractConformance checking is a key process mining task to confront the normative behavior imposed by a process model with the actual behavior recorded in a log. While this problem has been extensively studied for pure control-flow processes,...
