Abstract
Within the scope of virtual and networked enterprises, this paper introduces a novel methodology for the integration of quality management into enterprise modeling and allowing for quality certification of the whole enterprise. The ISO 9001:2000 standard is presented as an interesting starting point for the virtual enterprise quality management system implimentation. Quality management systems certification within the scope of ISO 10011 (or even ISO FDIS 19011) is however quite a difficult task. An alternative scenario for certification is therefore proposed.

Abstract
This paper presents on-going research in the supply-chain management area. With this effort, we aim at bridging the gap between business process modelling in the supply chain and business process co-ordination by means of innovative workflow management tools. In this context we present the Supply Chain Operation Reference Model (SCOR) and illustrate its usage in a Civil Construction Enterprise case study. The civil construction enterprise presents, usually, a distributed organisational structure (strategic enterprise, construction sites, warehouses, head-offices, etc.), and operates in a transient and variable environment, according to the collection of works in progress. A common scenario is the construction process that involves the interaction with several suppliers and the co-ordination of many smaller firms (subcontractors), normally coordinated by one contractor. The relationship with the enterprise suppliers as well as between contractor and sub-contractor features a clear Source-Make-Deliver and Return pattern, demanding coordination and interoperability along those processes that cross the enterprise boundaries. The SCOR model process-orientation greatly facilitates supply chain business process decomposition, fostering therefore greater effectiveness process integration along the supply chain, The paper concludes with a proposal of new business process management concepts to be supported by novel distributed workflow management tools.

Abstract
The COBIP UR4003 Project is running under the EC Telematics Application Programme and aims at demonstrating the usage of workflow tools in the management of telework decentralized activities. This paper presents an overview of the COBIP system, and its pilot implementation at TECNOTRON head offices in Lisbon.

Abstract
This paper focuses on the telework support to the so-called Small Information-based Organisations, where all activities involve information processing and transfer, usually among sub-contracted teleworkers. Most of these companies run by managing multiple parallel projects, i.e. one-of-a-kind business processes, each project usually involving remote activity execution by teleworkers. There is therefore a clear demand for workflow management systems supporting telework, featuring facilities that further enhance traditional office automation systems by filling the required support to geographically distributed co-operative work. The work presented was undertaken during a telework workflow management system requirements' specification, to support the so-called Small Information-based Organisations. To this end, we analysed the virtual enterprise life cycle, identifying the required modelling tool types for each of the required steps. The consecutive project steps from project planning to co-ordination were then identified, with special relevance to the definition of the so-called execution primitives and to the support of human interaction through the speech-act theory. This approach allowed the description of a consistent life-cycle approach from project planning to coordination.

Abstract
This paper presents an overview of the evolution of factory communications and related standards, ranging from industrial network standards' such as MAP(2), up to distributed platforms like OSF/DCE3 and OMG/CORBA(4). This overview has a particular emphasis on the advantages and constraints of distributed platforms as a means to support shop floor communications. The underlying work stems from and complements that of a previous paper (Santos et al.,1997) presenting a specific view on distributed platforms towards CIMOSA integrating infrastructure implementation.

Abstract
The Modelling Workbench briefly described in this paper was the result of a research project undertaken at the INESC Porto. It was the outcome of the integration of a SDL (Specification and Description Language) software modelling constructs into Simple++, an object-oriented material flow modelling and simulation tool, as well as its further integration with a CASE tool. The modelling environment provided by this Modelling Workbench supports the integrated modelling of material and information flow. Copyright (C) 1998 IFAC.
