Reference Models for Virtual Enterprises

This paper analyses different types of Reference Models (RMs) applicable to support the set up and (re)configuration of virtual enterprises (VEs). RMs are models capturing concepts common to VEs aiming to convert the task of setting up of VE towards a configuration task, and hence reduce the time needed for VE creation. The RMs are analysed through a mapping onto the Virtual Enterprise Reference Architecture (VERA) created in the IMS GLOBEMEN project based upon GERAM.

Reference models supporting enterprise networks and virtual enterprises

This article analyses different types of reference models applicable to support the set up and (re)configuration of Virtual Enterprises (VEs). Reference models are models capturing concepts common to VEs aiming to convert the task of setting up a VE into a configuration task, and hence reducing the time needed for VE creation. The reference models are analysed through a mapping onto the Virtual Enterprise Reference Architecture (VERA) based upon GERAM and created in the IMS GLOBEMEN project.

Use of GERAM as Basis for a Virtual Enterprise Framework Model

In the IMS-project Globeman21, the enterprise reference architecture GERAM was used as basis for creation of a virtual enterprise framework model. The model was used to map different industrial pilot projects, to classify virtual enterprise concepts, and as underlying structure for a virtual enterprise management methodology. The paper gives a survey of the use of GERAM and the results obtained.

Fast Tracking ICT Infrastructure Requirements and Design, Based on Enterprise Reference Architecture and Matching Reference Models

The Globemen Consortium has developed the virtual enterprise reference architecture and methodology (VERAM), based on GERAM and developed reference models for virtual enterprise management and joint mission delivery. The planned virtual enterprise capability includes the areas of sales and marketing, global engineering, and customer relationship management. The reference models are the basis for the development of ICT infrastructure requirements. These in turn can be used for ICT infrastructure specification (sometimes referred to as ‘ICT architecture’).Part of the ICT architecture is industry-wide, part of it is industry-specific and a part is specific to the domains of the joint activity that characterises the given Virtual Enterprise Network at hand. The article advocates a step by step approach to building virtual enterprise capability.

DEVELOPING THE BUSINESS MODEL - A METHODOLOGY FOR VIRTUAL ENTERPRISES

Enterprises co-operate with other enterprises in all phases of product life cycle to achieve cost reduction, increase their operational flexibility, and allow them to focus on core competencies. The preferred method for co-operation can be anything from long term alliances between partners in fixed supply chains — to a goal oriented, project focused co-operation as it is usually done in virtual enterprises (VEs).

Assessing Ability to Execute in Virtual Enterprises

The state of the art in ICT enables integration beyond the application per se, but this requires assessment and reconciliation of business processes. This paper describes this challenge to true co-operation in a virtual enterprise, focusing on industries for one-of-a-kind production. It explains why expressive modelling is important in the assessment process, by introducing the underlying mechanisms of inter-subjective maintenance of mental models. Finally, the paper discusses the future of assessment and auditing services in the context of business-to-business e-commerce.
