Preserving the Context of Interrupted Business Process Activities

Bassil, Sarita ; Rinderle, Stefanie ; Keller, Rudolf K. ; Kropf, Peter ; Reichert, Manfred

In: Enterprise Information Systems VII, 2005, vol. 3, p. 149-156

The capability to safely interrupt business process activities is an important requirement for advanced processaware information systems. Indeed, exceptions stemming from the application environment often appear while one or more application-related process activities are running. Safely interrupting an activity consists of preserving its context, i.e., saving the data associated with this...

Addressing Dynamism in E-negotiations by Workflow Management Systems

Bassil, Sarita ; Benyoucef, Morad ; Keller, Rudolf K. ; Kropf, Peter

In: Proceedings of the 13th International Workshop on Database and Expert Systems Applications (DEXA 02), 2002, p. 655–659

Workflows (Wfs) are a major enabling technology for e-commerce. In our research, a Combined Negotiation (CN) is modeled and enacted using Wf technology. The model-ing task captures the sequencing of the individual negotia-tions as well as the dependencies between them, and the enacting task runs the model. A CN support system (CON-SENSUS) is used by the user to perform both tasks. Sup-porting...

A Dynamic Approach to Multi-transfer Container Management

Bassil, Sarita ; Bourbeau, Benoît ; Kropf, Peter ; Keller, Rudolf K.

In: Odysseus, 2nd International Workshop on Freight Transportation and Logistics, 2003, p. 1-3

This paper introduces a dynamic approach to manage the processing of client requests in a multi-transfer container transportation (MTCT) system. At the operational level, this type of system is faced with a continuously changing environment. In this context, the need for dynamic creation and adaptation of solutions is of utmost importance. The adopted approach is based on a two-layer framework...

NADIM-Travel: A Multiagent Platform for Travel Services Aggregation

Ben Ameur, Houssein ; Bédard, François ; Vaucher, Stéphane ; Kropf, Peter ; Chaib-draaa, Brahim ; Gérin-Lajoie, Robert

In: 11th International Conference on Information Technology Tourism (ENTER), 2004, p. 1-12

With the Internet as a growing channel for travel services distribution, sophisticated travel services aggregators are increasingly in demand. A travel services aggregation platform should be able to manage the heterogeneous characteristics of the many existing travel services. It should also be as scalable, robust, and flexible as possible. Using multiagent technology, we designed and...

Multiagent auctions for multiple items

Ben Ameur, Houssein ; Chaib-draaa, Brahim ; Kropf, Peter

In: Proceedings of the Third International Bi-Conference Workshop on Agent-Oriented Information Systems (AOIS-2001), 2001, p. 33-40

Available resources can often be limited with regard to the number of demands. In this paper we propose an approach for solving this problem using the mechanisms of multi-item auctions for allocating the resources to a set of software agents. We consider the resource allocation problem as a market with vendor and buyer agents participating in a multi-item auction. The agents exhibit different...

NeOS: Neuchâtel Online System

Sturzrehm, Heiko ; Aubert, Frederic ; Kropf, Peter ; Corfu, Randoald

In: International Journal of Online Engineering (iJOE), 2008, vol. 4, no. 2, p. 17-23

Most online courses include training assignments and offer various forms of tests to evaluate the students’ performance. Some courses, in particular computer sciences courses, require elaborate hands-on training experiences. The NeOS Framework presented in this paper proposes an e-learning tool developed supporting in particular hands-on training through programming exercises. The user locally...

Towards Electronic Marketplaces: A Progress Report

Babin, Gilbert ; Crainic, Teodor Gabriel ; Gendreau, Michel ; Keller, Rudolf K. ; Kropf, Peter ; Robert, Jacques

In: 4th International Conference on Electronic Commerce Research (ICECR-4), 2001, p. 1-24

Market design is becoming a very important research topic in the context of the electronic economy. Two factors explain this trend: (1) the creation of new markets to facilitate deregulation (telecommunication frequencies, electric power, etc.) and (2) the emergence of strategic analysis and of experimental economics. E-commerce tools will contribute to the emergence of more structured...

aKIA Automobile : a Multi-Agent System in E-Commerce

Kia, Abbas ; Aïmeur, Esma ; Kropf, Peter

In: 5th International Conference on Electronic Commerce Research (ICECR-5), 2002, p. 1-10

Electronic commerce is a domain where agent technologies are well suited. The search and retrieval of product information is crucial in every E-commerce system. While some systems provide the user just with a fixed selection of products, others offer a wide variety of products with different characteristics. In this case, the system must provide means to efficiently and accurately search and...

Towards an agent-basedapproach for multimarket package e-procurement

Benameur, Houssein ; Vaucher, Stéphane ; Gérin-Lajoie, Robert ; Kropf, Peter ; Chaib-draaa, Brahim

In: 5th International Conference on Electronic Commerce Research (ICECR-5), 2002, p. 1-13

While most e-commerce research focuses on one market based problems, less work has been done on mul-timarket aggregation. Nowadays it is important to address the multimarket package e-procurement problem if we want to acquire a combination of goods and services from different suppliers and service providers. To achieve this, one should address the issues pertaining to identifying of a company's...

A teamwork test-bed for a decision support system

Chaib-draaa, Brahim ; Kropf, Peter ; Paquet, Sébastien

In: 4th EUROSIM Congress, 2001, p. 1-6

Resource management in complex socio-technical systems (as management and control (road, rail, sea, air), industrial engineering systems, transportation logistics, etc.) is a central and crucial process. The many diverse components involved together with various constraints such as real-time conditions make it impossible to devise exact optimal solutions. In this article, we present an approach...
