....systems (CCS) 40] use an atomic message exchange mechanism to model communications among processes. They clearly specify communication events among processes, but not the interleaving of events inside parallel processes. Examples of languages that support this model of computation are Lotos [12], and Occam [48] Asynchronous message passing models of computation, such as Kahn s process networks [25] and dataflow models [35] use FIFO queues to model the communication among processes. Only events within the same communication channel are strictly ordered, while the ordering among events ....

....2.4) 2.1 Operational semantics An operational semantics formalizes the notion of a step in an execution of a system. Amalia currently supports a restricted form of operational semantics suitable for notations that describe synchronization of actions in behaviors of a system, such as LOTOS [2], Esterel [1] or propositional linear time temporal logic [12] For specificity, we illustrate concepts in this paper using a subset of the LOTOS notation. A brief description of this subset is provided in Appendix A. If P denotes a LOTOS process, then a step of P is a pair (a; P ) where a ....

Several tutorials for Lotos are available, e.g. BB88, Tur93] The design of Lotos was motivated by the need for a language with a high abstraction level and a strong mathematical basis, which could be used for the description and analysis of complex systems. As a design choice, Lotos consists of two orthogonal sub languages: The data part of ....

....the building control context, but could also prove to be valuable in the domain of telecommunication systems. Several feature interaction detection approaches have been presented in the literature. In [5] an approach that detects undesirable interactions by employing Use Case Maps [6] and LOTOS [7] is introduced. After features have been semi formally described with Use Case Maps, these features are formally defined with LOTOS, which then can be used for verification. Other authors also propose using formal description techniques for the purpose of interaction detection. In [8] and [9] ....

Introduction The formal description technique LOTOS [BoB87, ISO8807] is an expressive specification language for concurrent and distributed systems. The flexibility of its operators generally allows clear and intuitive descriptions in various specification styles. However, the use of LOTOS has also revealed, or confirmed, some weak points of the ....

....in unfortunate ways. If such a delay is used as the second operand to the LOTOS disabling operator then the combined behaviour no longer enjoys the simple recursive definition normally possible by unwinding the disabling operator as a choice between the initial actions of its two operands [2], because the remaining delay period must change each time an uninterrupted action occurs. In effect, the delay operator changes the semantics of surrounding operators 6 Conclusion We have defined, and demonstrated the application of, a new real time process algebra, based on CCS. It offers ....

After a brief description of the Equicrypt protocol and its modelling in the formal language LOTOS [ISO 8807, BoB87] at an appropriate abstraction level, we will describe the verification process. We state some desired safety properties and formalize them. Then we describe a generic intruder process and its modelling, and show that some properties are falsified in the presence of this intruder. The ....

We also address the relationship between specification style and formal description in the specification language LOTOS [17, 3]. We illustrate this with simple examples in LOTOS. The interested reader may find more complex examples of these styles, based on the application of LOTOS for large scale specifications, in [29, 32, 20] Some considerations concerning styles of specification of abstract data types in LOTOS can be ....
