Abstract
This paper describes an attempt to design an "Order Promise" system to support decision making in the so-called Virtual Enterprises. In this framework, planning and control activities are very complex, and have to take place both within the enterprise and across the whole supply network in order to achieve high levels of performance. This work is part of a broader project with a particular focus on the microelectronics industry which is a good example of Virtual Enterprise, and where a quick response to the customers needs and to unpredictable changes in production conditions is considered a major factor for success.

Abstract
Current market dynamics require European SME's to focus on complex products manufacturing and to build non-hierarchical business networks, to assure competitiveness and sustainability. Such trend demands appropriate methods for network formation and management, including reference collaboration processes and supporting ICT tools. This paper presents a framework to support SME's in the creation and management of non-hierarchical networks designed and developed within the European RTD project Net-Challenge. This framework includes methodologies, processes and ICT decision support tools aiming at the efficient creation and management of these networks assuring quick response times and competitive and differentiated offerings.

Abstract
There is currently an increasing interest in exploring the opportunities for competitive advantage that can be gained by reinforcing core competencies and innovative capabilities through networks of industrial and business partners. This paper firstly identifies some of the gaps that exist within current information systems that claim to support eBusiness and eWork in networked enterprises and describes some of the general requirements of distributed and decentralised information systems for companies operating in networks. It goes on to cover some principles for the design of a distributed IS providing an advanced infrastructure to support general co-operation, particular methodologies for co-operative and collaborative planning and guidelines for network set-up and support. The present work is one of the areas currently being delivered as part of the Europe-an IST consortium called Co-OPERATE. A distributed and decentralised information system, based on an architecture of agents and extensively using the internet, is being designed and implemented as a means to provide new and more powerful decision support tools for networked enterprises.

Abstract
Markets today are characterized by enormous uncertainty in demand that combined with the increasing complexity of new products and competition, has forced companies to adopt new collaboration strategies with its business partners. SMEs need to form non-hierarchical networks where they can complement their capabilities and resources, achieve higher added value and higher control of the business. In these environments, decision making becomes decentralized and operations' planning presents new challenges and becomes more collaborative. An integrated solution for non-hierarchical networks collaborative planning is presented in this paper. The solution proposed includes two collaborative planning scenarios (aggregate and detailed), applied in different phases of non-hierarchical networks' lifecycle, which allows SME's to negotiate prices and delivery times in a collaboratively way. The solution considers requirements from companies belonging to three different industrial sectors, assuring its wide applicability. © 2011 Research Institute for Ope.

Abstract
This paper presents an innovative approach in supporting the operation of complex equipment. The concept was developed in the context of the KoBaS project (Knowledge Based Customized Services for Traditional Manufacturing Sectors Provided by a Network of High Tech SMEs) whose main objectives are the development of new knowledge based tools for cut intelligent use and management of more sophisticated manufacturing machines; and the creation of an innovative extended network of high-tech SMEs for use, customize, support and make business out of the new development tools. As a concrete example the paper presents a KoBaS solution based on the machine Maintenance. This solution allows one to know the machine condition, to detect and diagnose machine failures, to manage ordinary and extraordinary maintenance plans and maintenance work orders and to provide training support for maintenance interventions.

Abstract
This paper describes an <> system to support decision making in the planning processes of Virtual Enterprises, viewed as networks of different units, namely plants, logistic centres and storage facilities. The system aims at improving customer due date calculation, and is intended to be a multi-site planning tool to co-ordinate local activities across the Virtual Enterprise network. It is based on the use of aggregate information and on a set of local rough capacity models. This work is part of a broader project with a particular focus on the microelectronics industry. Companies of this industry are a good example of Virtual Enterprises, where a quick response to the customers needs and to unpredictable changes in production conditions is considered a major factor for success.
