Description

The current trend in eBusiness and eCommerce is towards networked solutions. Autonomous enterprises join networks of business driven alliances, virtual enterprises, to achieve added value and more business opportunities. At the same time the single enterprises concentrate on their co re business outsourcing other functionality to other enterprises.

Each member organization in a virtual enterprise offers services for others to use inside the virtual organization. The services in a virtual enterprise (VE) create more sophisticated services or a business scenario. An example case of this is a supply chain formed to take care of su pplying goods to a retail chain or buying and delivering wood from forests to paper mills and timber mills.

The virtual enterprises are bound together by electronic contracts which are negotiated during the setup phase of a virtual enterprise. During the negotiations the prospective participants of the virtual enterprise negotiate essential technical, semantical, and business related const raints, policies, and obligations each participant has.

This research seminar studies the interoperability challenges in inter-enterprise computing environments where loosely coupled business collaborations and virtual enterprises are to be established between autonomous enterprise systems. The individual enterprises publish their services using a middleware platform following a service-oriented architecture style. Inter-enterprise business processes are then used for composing the functionalities provided by services to collaborations fulfilling the goals and requirements of some business case or context. Such a framework requires for concepts, methods and mechanisms for establishing interoperable collaborations conjoining functional services, enterprise policies, social actors and business needs.

Prerequisites

As the seminar is part of Master-studies, a participant must have completed his / her Bachelor studies before attending (especially a course on "Scientific Writing"). This research seminar is oriented towards collaborative and interoperable computing, distributed systems and software engineering disciplines. We especially recommed that participants have completed some of the following courses (or similar): "Distributed Systems", "Middleware", "Internet Protocols" and "Software architecture".

Seminar format

Abstract (workplan). Length 1-2 pages. Includes a preliminary table of contents, a list of the most important references and an abstract. The abstracts are published and must be ready on the 2nd week of the seminar following the opening session.
Paper Seminar papers are published at the web-pages one week before the oral presentation. Paper format:
- Length 15-20 pages;
- Font size: 12 pt;
- Spacing: 1.5;
- One-column text;
- Delivered in PDF format
Paper presentation and structure must comply with criteria given for a scientific work (references, structure, writing style...). The papers are delivered (in pdf format) to the instructors one week before the oral presentation, at last (e-mail addresses at the top of this page).
Oral presentation Length of an oral presentation is approximately 70 minutes. Rest of the time is reserved for discussion. That is, there is one presentation per seminar session.
Active participation A student attending a seminar is expected to participate actively in discussion and providing feedback. Please read the seminar paper before an oral presentation. Constructive critisism is provided anonymously on paper about the presentation and paper (take a piece of paper and a pencil with you to the sessions).
Evaluation criteria Seminar work will be evaluated on the basis of the paper, oral presentation and degree of participation.

Finally, look also for further instructions on seminar work in general at the department (only in Finnish)
