This paper presents and illustrates a strategic framework for designing and operating agile networked manufacturing systems. This framework allows to collaboratively plan, control and manage day-to-day operations and contingencies in a dynamic environment. The first section summarizes the NetMan organizational and collaboration strategy. It consists of a dynamic business method to organize and operate manufacturing activities through the configuration, activation and operation of a distributed network of inter-dependent and responsible manufacturing centers. Next, the concepts underlying this strategic framework as well as the technical implications of such an approach, are illustrated, using a detailed case study inspired by a motorcoach industrial partner.

In this paper, the NetMan2 project is presented. NetMan aims to develop an operation system designed to support operations in an agile manufacturing network. It provides a framework to design responsibility-based networked manufacturing systems. The NetMan project also illustrates a collaborative business framework designed to operate agile manufacturing networks in a dynamic environment. This paper delves further into this aspect. In the first section, the main concepts of the NetMan strategic framework are summarized, building on previous studies that have influenced the development of this approach. Thus, the concepts of NetMan centers and NetMan networks are introduced and compared to other distributed manufacturing approaches such as bionic, fractal and holonic manufacturing systems. Then, the generic and specific aspects of collaboration underlying this approach as well as the multi-agent integration platform approach that is implemented in an agent-oriented prototype, are described,. The next section introduces the NetMan Operation System principles through the intensive use of a case study, inspired by the project's industrial partner Prévost Car from the Volvo Group. The implementation of business collaboration mechanisms into an operating manufacturing network are then discussed.

The main contribution of this paper concerns the presentation of the NetMan collaborative framework and the formalization of collaboration mechanisms in a distributed networked manufacturing system. Through this framework, some operational mechanisms that allow the creation of collaborative competencies within network enterprises have been concretized and partially implemented in a multi-agent prototype. Further development of this prototype concerns the implementation of most of these collaboration mechanisms. Thus, this approach proposes to develop such mechanisms in a distributed supply network to allow fast reactions and permit organizational and operational manufacturing agility. The conceptual research directions now concern the development of other collaborative mechanisms, with an emphasis on the external suppliers’ partnership, as well as the implementation of a NetMan-like job shop plant. Future conceptual developments also concern the classification of the centers’ interactions, as well as the formalization of information exchanges between centers and the collaborative planning aspects. They also concern the realization of a performance study through the implementation of distributed simulations (e.g., [77]). Their goals first concern the testing of the ability of the collaborative mechanisms to manage day-to-day operations and contingencies. Secondly, these simulations will be useful in order to formalize performance measures in distributed manufacturing systems.
