The proposed model adopts the concepts of the formalization and the automation of development processes. We propose a model for comparison between works, studies, and approaches in this field. We explore the advantages and limitations of more than fourteen approaches and research work.

Several studies and approaches have been proposed in this context, are devoted to the formalization of web services orchestrations and allow some verification of their behavior these approaches are partial solutions to the problem of development of the safe composition.

However, the operational semantics of each of the structures of these languages is not formally defined and they have limitations regarding the reasoning and the verification of the web services compositions. These languages are used to describe how the interactions between multiple services are coordinated to achieve a goal. Many languages allow expression of executable processes to implementing web services orchestration. Web services orchestration describes how web services can interact with each other from an operational perspective.

WSOA as service-oriented architecture (SOA) designs the software as services and uses the services as platforms. The security in web service oriented architecture (WSOA) development has become a critical need and goal. My technique is based on Interval Temporal Logic (ITL). The proposed model can check system behaviour at runtime in order to either guarantee satisfaction or detect violations of correctness properties. In this paper, I propose a Parallel Runtime Verification Framework (PRVF) that can handle systems which use message-passing based communication via synchronous execution mode. Therefore, sequential runtime verification framework can not handle systems that run in parallel due to the singularity issue of this kind of framework as they are built to handle a single system at a time, whereas for parallel systems a framework has to handle many systems at a time. For instance, as a correctness property of parallel systems, absence of deadlock has to be guaranteed and mutual exclusion mechanism has to be applied in case a resource is shared between more than one system and the parallelism form is true concurrency. Parallel systems have correctness properties different from correctness properties of sequential systems. Therefore, systems that run in parallel need a parallel runtime verification framework to monitor their behaviour and guarantee correctness properties. Parallel systems are more complicated than sequential systems. Runtime Verification (RV) is the discipline that allows monitoring systems at runtime in order to check the satisfaction or violation of a given correctness property.

In addition, various researchers have applied Tempura to hardware simulation and other areas where timing is important. In addition, ITL and its mature executable subset Tempura have been extensively used to specify the properties of real-time systems where the primitive circuits can directly be represented by a set of simple temporal formulae. Tempura provides an executable framework for developing and experimenting with suitable ITL specifications. Timing constraints are expressible and furthermore most imperative programming constructs can be viewed as formulas in a slightly modified version of ITL. Unlike most temporal logics, ITL can handle both sequential and parallel composition and o#ers powerful and extensible specification and proof techniques for reasoning about properties involving safety, liveness and projected time.

Interval Temporal Logic (ITL) is a flexible notation for both propositional and first-order reasoning about periods of time found in descriptions of hardware and software systems.
