Abstract:

The conversion of web services to semantic web comes the opportunity to automate various tasks. OWL-S plays a key role in describing web services behaviour. While ontology-based semantics given to OWL-S is structural rather than behaviourally oriented, we cannot automate an essential task in this field, verification. In this article, the mapping of OWL-S process model to Timed automata is investigated, which is a suitable formalism for real time systems modeling and automatic verification. Hence, this has led to not only enabling automatic verification but also covering problems related to automated verification of temporal quantitative properties as bounded liveness property. As a starting point, the OWL-S and sub entry of time ontologies for describing the timed behaviour of services has been chosen. A defined set of mapping rules is used to automatically encode control constructs defined in OWL-S and temporal information into timed automata. Also, it is shown how a Uppaal checker is used to check required properties formulated in TCTL. Finally, an EClinic case study is used to illustrate the technique.

Abstract:

Timed and register automata are well-known models of computation over timed and data words, respectively. The former has clocks that allow to test the lapse of time between two events, whilst the latter includes registers that can store data values for later comparison. Although these two models behave differently in appearance, several decision problems have the same (un)decidability and complexity results for both models. As a prominent example, emptiness is decidable for alternating automata with one clock or register, both with non-primitive recursive complexity. This is not by chance.This work confirms that there is indeed a tight relationship between the two models. We show that a run of a timed automaton can be simulated by a register automaton over ordered data domain, and conversely that a run of a register automaton can be simulated by a timed automaton. These are exponential time reductions hold both in the finite and infinite words settings. Our results allow to transfer decidability results back and forth between these two kinds of models, as well complexity results modulo an exponential time reduction. We justify the usefulness of these reductions by obtaining new results on register automata.

Abstract:

Timed automata are commonly recognized as a formal behavioral model for real-time systems. For compositional system design, parallel composition of timed automata as proposed by Larsen et al. [22] is useful. Although parallel composition provides a general method for system construction, in the low level behavior, components often behave sequentially by passing control via communication. This paper proposes a behavioral model, named controller automata, to combine timed automata by focusing on the control passing between components. In a controller automaton, to each state a timed automaton is assigned. A timed automaton at a state may be preempted by the control passing to another state by a global labeled transition. A controller automaton properly extends the expressive power because of the stack, but this can make the reachability problem undecidable. Given a strict partial order over states, we show that this problem can be avoided and a controller automaton can be faithfully translated into a timed automaton.

Abstract:

Given a timed automaton A and a control state q , does there exist a run of A that visits q ? This problem of control state reachability in timed automata was posed in [Alur and Dill 1994] and is known to be PSPACE-complete. One does not hope to have efficient algorithms for this problem, in theory. Nevertheless, research in this subject over the last three decades has led to industry-strength award-winning tools implementing this problem. This topic continues to be an active area of research even now. In this article, we present one successful algorithmic framework for attacking this problem.

Abstract:

Event logs are often one of the main sources of information to understand the behavior of a system. While numerous approaches have extracted partial information from event logs, in this work, we aim at inferring a global model of a system from its event logs. We consider real-time systems, which can be modeled with Timed Automata: our approach is thus a Timed Automata learner. There is a handful of related work, however, they might require a lot of parameters or produce Timed Automata that either are undeterministic or lack precision. In contrast, our proposed approach, called TAG, requires only one parameter and learns a deterministic Timed Automaton having a good tradeoff between accuracy and complexity of the automata. This allows getting an interpretable and accurate global model of the real-time system considered. Our experiments compare our approach to the related work and demonstrate its merits.

Abstract:

Probabilistic timed automata are classical timed automata extended with discrete probability distributions over edges. We introduce clock-dependent probabilistic timed automata, a variant of probabilistic timed automata in which transition probabilities can depend linearly on clock values. Clock-dependent probabilistic timed automata allow the modelling of a continuous relationship between time passage and the likelihood of system events. We show that the problem of deciding whether the maximum probability of reaching a certain location is above a threshold is undecidable for clock-dependent probabilistic timed automata. On the positive side, we show that the maximum and minimum probability of reaching a certain location in clock-dependent probabilistic timed automata can be approximated using a region-graph-based approach.

Abstract:

For the Automata Theory Column, we have an article by B. Srivathsan on the reachability problem in timed automata. Ever since timed automata were introduced by Alur and Dill, they have been widely used in the verification of real-time systems. Their appeal comes from a simple definition that couples expressiveness with computational tractability. The control state reachability problem, which asks if there is a computation of a given timed automaton that reaches a given control state, is an important problem in this context and was shown to be decidable in PSPACE by Alur and Dill in their seminal paper. However, because of the central role this problem plays in verification, it has been extensively studied in the past 30 years. In this issue, Srivathsan lucidly articulates the main principles underlying modern approaches to solving this problem.

Abstract:

The language inclusion checking of timed automata is described as the following: given two timed automata M and N, where M is a system model and N is a specification model (which represents the properties that the system needs to satisfy), check whether the language of M is included in the language of N. The language inclusion checking of timed automata can detect whether a system model satisfies a given property under the time constraints. There exist excellent studies on verifying real-time systems using timed automata. However, there is no thorough method of timed automata language inclusion checking for real-life systems. Therefore, this paper proposes a language inclusion checking method of timed automata based on the property patterns. On the one hand, we summarize commonly used property patterns described by timed automata, which can guide people to model the properties with time constraints. On the other hand, the system model M often contains a large number of events, but in general, the property N only needs to pay attention to the sequences and time limits of a few events. Therefore, the timed automata language inclusion checking algorithm is improved so that only the concerned events are required. Our method is applied to a water disposal system and it is also evaluated using benchmark systems. The determinization problem of timed automata is undecidable, which may lead to an infinite state space. However, our method is still practical because the properties established according to property patterns are often deterministic.

Abstract:

A decentralized controller design approach is developed for the timed discrete event systems which are modelled by timed automata in this work. An approach, called augmentation, is presented to obtain the new modelling method such that each unit delay of any event represents a pair of new state and event. The augmented automata model, obtained by using this approach, is considered to design a decentralized controller. This controller design approach is developed such that the local controller is designed for each subautomaton, obtained by using overlapping decompositions and expansions and these controllers are then combined to obtain a decentralized controller for the given timed automaton. The designed decentralized controller guarantees the unreachability of a forbidden state in the considered automaton.
