Cross organisational compatible workflows generation and execution

With the development of internet and electronics, the demand for electronic and online commerce has increased. This has, in turn, increased the demand for business process automation. Workflow has established itself as the technology used for business process automation. Since business organisations have to work in coordination with many other business organisations in order to succeed in business, the workflows of business organisations are expected to collaborate with those of other business organisations. Collaborating organisations can only proceed in business if they have compatible workflows. Therefore, there is a need for cross organisational workflow collaboration. The dynamism and complexity of online and electronic business and high demand from the market leave the workflows prone to frequent changes. If a workflow changes, it has to be re-engineered as well as reconciled with the workflows of the collaborating organisations. To avoid the continuous re-engineering and reconciliation of workflows, and to reuse the existing units of work done, the focus has recently shifted from modeling workflows to automatic workflow generation. Workflows must proceed to runtime execution, otherwise, the effort invested in the build time workflow modeling is wasted. Therefore, workflow management and collaboration systems must support workflow enactment and runtime workflow collaboration. Although substantial research has been done in build-time workflow collaboration, automatic workflow generation, workflow enactment and runtime workflow collaboration, the integration of these highly inter-dependent aspects of workflow has not been considered in the literature. The research work presented in this thesis investigates the integration of these different aspects. The main focus of the research presented in this thesis is the creation of a framework that is able to generate multiple sets of compatible workflows for multiple collaborating organisations, from their OWLS process definitions and high level goals. The proposed framework also supports runtime enactment and runtime collaboration of the generated workflows

IT supported business process negotiation, reconciliation and execution for cross-organisational e-business collaboration

In modern enterprises, workflow technology is commonly used for business process automation. Established business processes represent successful business practice and become a crucial part of corporate assets. In the Internet era, electronic business is chosen by more and more organisations as a preferred way of conducting business practice. In response to the increasing demands for cross-organisational business automation, especially those raised by the B2B electronic commerce community, the concept of collaboration between automated business processes, i.e. workflow collaboration, is emerging. Otherwise, automation would be confined within individual organisations and cross-organisational collaboration would still have to be carried out manually. However, much of the previous research work overlooks the acquisition of the compatible workflows at build time and simply assumes that compatibility is achieved through face-toface negotiation followed by a design from scratch approach that creates collaborative workflows based on the agreement resulted from the negotiation. The resource-intensive and error-prone approach can hardly keep up with the pace of today’s marketplace with increasing transaction volume and complexity. This thesis identifies the requirements for cross-organisational workflow collaboration (COWCO) through an integrated approach, proposes a comprehensive supporting framework, explains the key enabling techniques of the framework, and implements and evaluates them in the form of a prototype system – COWCO-Guru. With the support of such a framework, cross-organisational workflow collaboration can be managed and conducted with reduced human effort, which will further facilitate cross-organisational e-business, especially B2B e-commerce practices

Establishing and Maintaining Compatibility in Service Oriented Business Collaboration

Current composite web service development and management solutions, e.g. BPEL, do not cater for assessing and maintaining comparability of business partners during business collaboration development and management. It is our firm belief that to realize the vision of developing business collaborations on demand and on the fly while ensuring that collaboration between participants involved can take place, business collaboration design needs to apply software development principles and at the same time incorporate support for specification of relationships among requirements and capabilities of different participants. In this paper we introduce the business collaboration design framework, which uses a blend of design perspectives, facets and aspects to provide designers with the means to develop and deliver business collaborations in an effective and comprehensive manner. We then explore how compatibility in collaborations designs can be handled in a verifiable manner by establishing a traceability mechanism, which facilitates assessment of the impact of change on the diverse aspects of business collaborations.

Towards a business process model warehouse framework

This dissertation focuses on the re-use of business process reference models, available in a business process model warehouse, to enable the definition of more comprehensive business requirements. It proposes a business process model warehouse framework to promote the re-use of multiple business process reference models and the flexible visualisation of business process models. The critical success factor for such a framework is that it should contribute to minimise to some extent the causes of inadequate business requirements. The proposed framework is based on an analogy with a data warehouse framework, consisting of the following components: usage of multiple business process reference models as source models, the conceptual design of a process to extract, load and transform multiple business process reference models into a repository, a description of repository functionality for managing enterprise architecture artefacts, and motivation of flexible visualisation of business process models to ensure more comprehensive business requirements.Computer Science (School of Computing)M.Sc.
