“…However, this condition is usually not the case in business processes, given their high-level of abstraction. Instead, business processes mostly use loops to perform a certain task multiple times on different data, which can easily be aggregated to form a single input [38].…”

In this paper, we focus on the reliability and availability analysis of Web service (WS) compositions, orchestrated via the Business Process Execution Language (BPEL). Starting from the failure profiles of the services being composed, which take into account multiple possible failure modes, latent errors, and propagation effects, and from a BPEL process description, we provide an analytical technique for evaluating the composite process' reliability-availability metrics. This technique also takes into account BPEL's advanced composition features, including fault, compensation, termination, and event handling. The method is a design-time aid that can help users and third party providers reason, in the early stages of development, and in particular during WS selection, about a process' reliability and availability. A non-trivial case study in the area of travel management is used to illustrate the applicability and effectiveness of the proposed approach.

“…Partitioning BPEL processes has specific requirements such as the distributed elimination of death paths. Approaches for their partitioning are discussed in the work of Khalaf et al [15,14,16]. The authors of [10,9] claim that the work of Khalaf et al does not provide a complete solution for the partitioning of BPEL processes and only addresses certain specific aspects of BPEL.…”

Interorganizational business processes aim to integrate local processes to support the seamless cooperation of organizations. Process view approaches are an adequate method balancing the communication requirements for enabling collaboration and the required privacy hiding internals of private business processes. We focus on a top-down scenario for the development of interorganizational processes, where first an abstract global process is designed. Then each step of the global process is assigned to one of the partners and a local process is generated for each partner as a view on the global process. Finally, the partners implement or adopt their processes based on their views. We present an algorithm for the fully automatic generation of views for any block-structured input process with arbitrary partner assignments, provide a method for merging the partner's views to reconstruct the global process and prove the correctness of the view generation method.

“…Of course, after assigning activities to fragments using some criteria, the actual work of creating and deploying executable fragments involves many technical details and is very dependent on the composition language. For BPEL, a detailed discussion can be found in the work by Khalaf and Leymann [22,23].…”

“…Figure 19 shows an adaptive search for service candidates for D ={name, address, ssn}, depending on a combination of a22, a 23 , and a 24 executed within a20. Each of these activities contributes some additional information, represented in the lower table in the figure.…”

“…Each of these activities contributes some additional information, represented in the lower table in the figure. In this case, a 22 must always be executed, and for a "big" loan, also at least one of a 23 or a24. If D was computed based on the minimal sharing (relation <s), we obtain candidates that certainly comply, and if it was computed based on < s , we obtain the set of all potential candidates.…”

A sharing-based approach to supporting adaptation in service compositions

Data-related properties of the activities involved in a service composition can be used to facilitate several design-time and run-time adaptation tasks, such as service evolution, distributed enactment, and instance-level adaptation. A number of these properties can be expressed using a notion of sharing. We present an approach for automated inference of data properties based on sharing analysis, which is able to handle service compositions with complex control structures, involving loops and sub-workflows. The properties inferred can include data dependencies, information content, domain-defined attributes, privacy or confidentiality levels, among others. The analysis produces characterizations of the data and the activities in the composition in terms of minimal and maximal sharing, which can then be used to verify compliance of potential adaptation actions, or as supporting information in their generation. This sharing analysis approach can be used both at design time and at run time. In the latter case, the results of analysis can be refined using the composition traces (execution logs) at the point of execution, in order to support run-time adaptation.
