- By the use of Web Service technologies and the Internet it is possible to lay the foundation for virtual value chains that cross enterprise boundaries. As the number of services and their interaction grow, it is evident that the flow of message exchange between services needs to be coordinated in a structured way. Executable process languages such as BPEL are proposed as an instrument for the coordination of services. Executable processes must be designed such that they solve technical coordination problems as well as provide a fundament for organizations to manage and monitor the progress of the business. In this paper we examine how the design of executable processes is affected by both technical and business issues. Furthermore, we examine a set of architectures that enable the use of executable processes to cater to both business and technical needs. We provide fundamental guidelines on how to apply the architectures.

Service-Based Processes : Design for Business and Technology

Konferensbidrag (refereegranskat)abstract
- Composition of software services is a fundamental part in supporting enterprise business processes. Designed properly, executable processes can be used to closely support business processes by the integration of existing software services. In order to support business processes the design of the executable process must closely follow the business events and activities, as perceived by business actors. However, the design must also consider technical issues such as limitations in existing technology and systems. In this paper we examine how technical system constraints influence the realization of business processes. Based on this examination we present a set of realization types that describes the transformation from a business process into its realization as an executable process. We also propose design criteria that need to be adhered to in order to cater to both business and technical needs.

- Business-to-Business (B2B) e-commerce is emerging as trading parties are attempting to integrate electronically, to automate exchange of their services. To be able to collaborate, enterprise processes must expose compatible public behavior. It is a common need for a company to collaborate a business with many partners. A problem is that, even agreeing on information to be exchanged, the partners usually expose different requirements for protocol and logic of interactions. Therefore, it becomes necessary for companies to redesign process models to accommodate to a new partner. As the result, the company must engage considerable resources for designing and verifying new process specifications, as well as for maintaining them. In this paper, we propose a framework for flexible modeling of enterprise processes, to support a larger scale of B2B integrations. The proposal is based on a set of concepts of flexibility that enable partial process specifications, depicting thus a wider scope of business scenarios that a company is willing to conform in a B2B context. The complete process specification is made after B2B parties agree on a strict public protocol and enforced by runtime transformations. The proposed framework for flexible process modeling is aimed to speed up integration of partner processes as it increases ability for process matching without requiring changes in their design.

- E-Business is constantly growing as organizations are trying to integrate electronically in order to automate exchange of information and services. To construct inter-organizational processes, the involved enterprises must agree on ways how to invoke process services on the business partner's system. A problem is that existing processes are so diverse in protocols, activity and message forms that it is impossible to start collaboration without comprehensive adaptations. In this paper, we propose a framework for interoperation of processes, which is based on requirements for equivalence of document exchanges. We argue that this level of equivalence is sufficient to enable existing enterprise processes to collaborate without internal redesign. The proposed framework is aimed to facilitate process collaboration by using a mediator layer to perform necessary adaptations, while minimizing requirements for process similarity.

Modeling Image Processing Tasks As Flexible Workflows for Improved Quality of Service

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Processing of nontrivial images is a difficult task performed throughout a set of ordered steps. Besides the basic functionality that a process must satisfy, quality of service goals are to be met. Images should be processed within a certain time and a certain quality should be attained. To manage image-processing tasks in the optimal way, the process goals must be defined explicitly and their fulfillment has be controlled. Modeling image-processing tasks with workflows would enable control of the fulfillment of goals. In addition, by introducing flexible semantics in the workflow, the process could be executed along optimal execution alternatives. In this paper, we propose an approach to model the class of image processing tasks with workflows that would, based on the extended semantics, allow for flexibility in the process execution toward optimal goals fulfillment.
