EDOC: meeting the challenges of enterprise computing

An increasing demand for interoperable applications exists, sparking the real-time exchange of data across borders, applications, and IT platforms. To perform these tasks, enterprise computing now encompasses a new class of groundbreaking technologies such as Web services and service-oriented architecture (SOA); business process integration and management; and middleware support, like that for utility, grid, peer-to-peer, and autonomic computing. Enterprise computing also influences the processes for business modeling, consulting, and service delivery; it affects the design, development, and deployment of software architecture, as well as the monitoring and management of such architecture. As enterprises demand increasing levels of networked information and services to carry out business processes, IT professionals need conferences like EDOC to discuss emerging technologies and issues in enterprise computing. For these reasons, what started out as the Enterprise Distributed Object Computing (EDOC) conference has come to encompass much more than just distributed objects. So this event now used the name International EDOC Enterprise Computing Conference, to recognize this broader scope yet also retain the initial conference's name recognition

Developing a grid computing system for commercial-off-the-shelf simulation packages

Today simulation is becoming an increasingly pervasive technology across major business sectors. Advances in COTS Simulation Packages and Commercial Simulation Software have made it easier for users to build models, often of large complex processes. These two factors combined are to be welcomed and when used correctly can be of great benefit to organisations that make use of the technology. However, it is also the case that users hungry for answers do not always have the time, or possibly the patience, to wait for results from multiple replications and multiple experiments as standard simulation practice would demand. There is therefore a need to support this advance in the use of simulation within today’s business with improved computing technology. Grid computing has been put forward as a potential commercial solution to this requirement. To this end, Saker Solutions and the Distributed Systems Research Group at Brunel University have developed a dedicated Grid Computing System (SakerGrid) to support the deployment of simulation models across a desktop grid of PCs. The paper identifies route taken to solve this challenging issue and suggests where the future may lie for this exciting integration of two effective but underused technologies

From business process models to distributed software architecture

While examining complex business processes we have discovered that most of them are software-driven, i.e. most business processes depend on software systems. One approach to specifying these software systems is the development of business process models and the derivation of requirements for the software systems supporting them. In other words: business process models represent some sort of requirements for software systems needed to support the processes [ 11. A closer look at the world of business process engineering [2] shows that more and more business processes are distributed [3,4]. Insurance companies for example have their main headquarters, many offices and vast numbers of agents. They all need access to central software systems, and they have their own software, too. Despite this distribution, couplings between dispersed systems are in their infancy [5]. Interfaces based on EDI or even based on a distributed software are frequently missing [6]. Instead of that, insurance agents have to fill out application forms either manually or within their local software system. They have to send the forms by letter post to the office where the data will be copied again manually into the central software. Here there are special software routines for verifying the application data and for the decision whether an application will be accepted or not. hXmkSiOn to make digital or hard copies of all ar pafi of this wo,.k for personal or classroom use is granted without fee provided that copies arc not made or distributed for prolit or commercial advantage and that copies bear this notice and the full citation on the first page.

Model-Supported Business Alignment of IT — Conceptual Foundations

Business Information Technology (IT) alignment focuses on the efficient support of business processes by IT. Therefore,existing software artifacts are addressed by business process models. When the processes change, however, there is a need toadjust the supporting software systems. Thus, already during the design phase of business process models, IT artifacts shouldto be considered. The instrument of conceptual modeling gains wide acceptance, especially in the health care sector todescribe and manage clinical processes, such as Clinical Practice Guidelines (CPG) and Clinical Pathways (CP). There are noholistic approaches so far that provide the alignment between these two concepts and ensure the quality of treatment and theconsistent adaptation of a Hospital Information System (HIS), in particular the hospital’s Workflow Management System(WfMS). To link business process models and the WfMS, the Description Kit Approach (DKA) is used to prepare conceptualmodels to make them automatically analyzable. It is suggested that at an early stage of the modeling process the use ofguidelines has an substantial benefit for avoiding integration conflicts in conceptual models. Furthermore, due to the way theapproach bridges the semantic gap, changes of business requirements as well as technical implementation restrictionsinfluence each other. This results in an ongoing system development process that can be interpreted as a permanentmanagement of application systems. Our results contribute to model-based management theories that have so far neglectedthe distributed construction of conceptual models

[email protected] - Agent Based Support of Clinical Processes

In this paper we present a system for agent-based support of clinical processes. We describe the basic engineering concept, along with specific simulation and testing scenarios for agent-based software engineering. Another important focus is the integration of existing agent or healthcare standards like FIPA, DICOM and HL7. Objectives of our research activities in this project are: a substantial increase of the efficiency of hospital process management as well as the development of a specific goal oriented requirements engineering methodology. As most important challenges of the healthcare domain we have identified on the one hand individualized, patient oriented processes in diagnostics, therapy, nursing and administration and on the other hand extremely distributed decision processes and strong local (individual) autonomy with a high degree of situational dynamics. The example scenario on „clinical trials“ illustrates how the system shall support distributed clinical processes and how it interacts with other multiagent systems within the Agent.Hospital Framework and hospital information systems in the eHealth Lab introduced in this paper. The system development is part of the German Priority Research Program (SPP) 1083 “Intelligent Agents and their application in business scenarios”

Collaborative Requirements Engineering Notation for Planning Globally Distributed Projects

Requirements engineering represents a critical phase of the software development lifecycle in which requirements describing the functional and non-functional behaviors of a system are elicited, modeled, analyzed, negotiated, agreed, and specified. In traditional software systems these tasks are typically performed in face-to-face meetings between requirements engineers and the project level stakeholders. However, in today’s global software development environment, it is becoming increasingly commonplace for stakeholders to be dispersed across multiple geographical locations and time zones. Under these circumstances, face-to-face meetings become expensive, and often impossible to facilitate, and as a result the success of the requirements process relies, at least partially, on tools and processes that support distributed communication and collaboration. To investigate the challenges and effective practices for performing requirements activities in distributed environments, we conducted a series of in-depth interviews with project managers and business analysts who have worked with non-co-located stakeholders. Since many project managers fail to plan and deploy the necessary infrastructures to support quality communication, and in practice requirements are often elicited and managed via email exchanges; we introduced a visual modeling notation to help project managers proactively plan the collaboration infrastructures needed to support requirements-related activities in globally distributed projects. An underlying meta-model defines the elements of the modeling language, including locations, stakeholder roles, communication flows, critical documents, and supporting tools and repositories. The interview findings were further analyzed to identify practices that led to success or created significant challenges for the projects; resulting in a set of patterns for globally distributed requirements engineering

SIGPAM Workshop on Process Automation and Management

The trend towards e-business is increasing the complexity of intra-organizational and inter-organizational processes. To accommodate these needs, organizations must integrate their services in real time to attract and maintain customers. In the last few years, process automation and management have become a central theme in many businesses. Research areas addressing problems in this domain include: electronic commerce, business process reengineering, enterprise application integration, knowledge process management, groupware, workflow automation, electronic markets, and computer supported collaborative work. These areas have unique research approaches, but have a common interest in advancing process automation to support intra-organizational and inter-organizational work in the Internet era. Consequently, there is a great need to bring together researchers with diverse backgrounds to discuss process-related topics. The objective of this workshop is to provide a forum for researchers and practitioners interested in process automation and management to meet and exchange research ideas and results. The workshop promotes a range of research issues, though not limited to: · Business process facilitation in distributed environments · Change management in highly automated business processes · Integration of business processes in both intra- and inter-enterprises · Methodologies and tools of process automation and management · Managing business processes on the Web · Process aware system security · Process centric model driven architectures · Process flexibility, interoperability, and scalability · Process-driven knowledge delivery · Theories of conceptual, logical, and physical process modeling · Wireless process management systems · Workflow automation and management for virtual enterprises · Workflow-centric component-based software engineerin

Workflow support for simulation of service oriented B-to-C transaction

Computation technologies and computer tools offer varied resources for the implementation of applications of electronic commerce (e-commerce). The current organizational models are based on nets of associations that are integrated to achieve business objectives. Therefore, the effectiveness of the commercial operation doesn't only depend on an appropriate configuration of technologies but also on efficiency in the business services. Service-Oriented Architecture (SOA) is an architectural style for distributed computation that considers the creation and administration of business services. With Web Services the services can be published in the Web and accessed by applications independently from language and technology. In this work a workflow support for the modeling and simulation of applications of e-commerce based on services and technologies Web Services is proposed. Tools are applied of processes modeling, with their integration in TIBCO that result in the modeling of a process business to consumer (b-to-c), their simulation and the evaluation of metrics of performanceI Workshop Innovación en Sistemas de Software (WISS)Red de Universidades con Carreras en Informática (RedUNCI
