Modelling and verification of BPEL business processes

1998

We present an application of the Spin model-checker in Testbed, a framework for business process reengineering. Business processes are described by end-users of Testbed in a graphi-cal language with a causality-based semantics, called Amber. The Amber language contains various constructs describing actions, causality relations, disabling, interaction and hierarchical composition. Data entities are modelled as variables that are handled by the business processes. We present a validation methodology for business processes using model-checking techniques. In this approach, an Amber speciication is automatically translated into a state machine description in Promela, which is the input language of the Spin model-checker. The correctness properties, concerning both the behavioural aspects and the data entities used in the speciication, are checked on the resulting Promela program using Spin. A prototype veriication toolset has been developed and successfully applied to various examples i...

This paper proposes the use of model-checking software technology for the verification of workflows and business processes behaviour based on web services, namely the use of the SPIN model checker. Since the specification of a business process behaviour based on web services can be decomposed into patterns, it is proposed a translation of a well known collection of workflow patterns into PROMELA, the input specification language of SPIN. The use of this translation is illustrated with one business process example, which demonstrates how its translation to a PROMELA model can be useful in the web service specification and verification.

In this paper we describe modeling for verification of business process with Spin model checker. Our primary goal is the development of Promela language description for e-invoice web service. Modeling for verification follows Church's synthesis problem: for input scenario "dataflow" model, output is Promela model. Sequence of model transformations translates the scenario into the Promela language code. At the end whole process is illustrated with e-invoice web service example.

We formally define an abstract executable semantics for the Business Process Execution Language for Web Services in terms of a distributed ASM. The goal of this work is to support the design and standardization of the language. "There is a need for formalism. It will allow us to not only reason about the current specification and related issues, but also uncover issues that would otherwise go unnoticed. Empirical deduction is not sufficient." -Issue #42, OASIS WSBPEL TC. The language definition assumes an infrastructure for running Web services on some asynchronous communication architecture. A business process is built on top of a collection of Web services performing continuous interactions with the outside world by sending and receiving messages over a communication network. The underlying execution model is characterized by its concurrent and reactive behavior making it particularly difficult to predict dynamic system properties with a sufficient degree of detail and precision under all circumstances.

The 2009 Spring Simulation Multiconference (SpringSim'09) is an annual conference which covers state-of-the-art developments in computer simulation technologies, as well as scientific, industrial, and business applications. Areas covered include high-performance computing technologies, models and algorithms, GUI visualization technologies, communications and much more. Application disciplines covered include advanced telecommunication; computer systems; military, government & aerospace; environment, energy, and other industries. The conference includes keynote speeches presented by technology and industry leaders, technical sessions, professional development courses and seminars, as well as vendor exhibits. Scientists, engineers, managers, educators, and business professionals who develop or use simulation tools are invited to participate and present original papers. Proposals are solicited for papers, panels, tutorials, workshops, seminars, exhibits, social activities and for other presentation, discussion and sponsorship formats. People are always welcome to benefit by taking an organizing role. SpringSim'09 offers many ways to promote simulation products and to enhance corporate images. You are invited to use the Spring Simulation Multiconference in ways that best serve your interests.
