Towards a workflow-based integration architecture for business networking

Autores
Ferreira, DMR; Ferreira, JJP;

Publicação
Business Process Management Journal

Abstract
Purpose - The purpose of this paper is to show how workflow management can be applied in the context of business networking. Design/methodology/approach - The paper looks at workflow management systems (WfMSs) as an enterprise integration tool and, as such, it shows that WfMS require an appropriate integration infrastructure. The paper then describes how a WfMS that supports business networking can be built. Findings - It is found that business networking requires a decentralized, peer-to-peer (P2P) integration infrastructure. On the other hand, it is found that it is possible to develop a generic and reusable workflow engine. Both components are then integrated in order to come up with a solution that supports business networking. Research limitations/implications - Issues concerning information and document management are not addressed. Neither mechanisms of storage and retrieval of exchanged documents, nor the format/structure of those documents are specified. Practical implications - The paper assumes that enterprises will be willing to build up a P2P network where they will conduct their business-to-business (B2B) exchanges. Then, the proposed solution would allow their business processes to be linked without requiring tight coupling between their information systems. Originality/value - The paper is useful to IT strategists and researchers dealing with WfMS, B2B integration architectures and applications of P2P technology. © Emerald Group Publishing Limited.

Mashup Enabled Dynamic Capabilities in the Fuzzy Front-End of Innovation

Abstract
Innovation is today a widely used buzzword in the enterprises environments, because it is seen today as the support for long-term surviving and a lever for the creation of new and differentiated products or services. The Fuzzy Front-End of Innovation (FFE) is often experimental, involving strong interaction with the end-users. This enables the knowledge transfer from users, communities or Collaborative Innovation Networks to organizations. Enterprises may master a set of Dynamic Capabilities in order to manage, learn and integrate that shared knowledge. Today, using Web 2.0 applications, users are able to easily join together, share ideas, catalog information, spread and share their knowledge in a variety of ways. This paper presents a model to enable those Dynamic Capabilities using a Web 2.0 Mashup in the FFE of innovation.

Integrating information and material flow executable models, an SDL-based information flow modelling tool

Publicação
INTERNATIONAL JOURNAL OF COMPUTER INTEGRATED MANUFACTURING

Abstract
Continuous pressure for competitiveness increase led to the concept of enterprise integration. Within this context a modular approach to enterprise modelling, structuring it into manageable units which cooperate with each other according to identified needs and sharing information on request, is mandatory. The approach presented here encompasses a Modelling Workbench supporting the development of applications for the management and control of manufacturing operations: an integrated modelling and simulation environment providing both material and information flow modelling facilities, as well as the integration of material and information now executable models. Building on Simple++, a simulation tool supporting material flow modelling, a class library allowing the use of SDL (Specification and Description Language) for information flow modelling and simulation was developed. The paper also illustrates the SDL environment concept and its significance in the integrated model, as well as its use for shop floor CIM systems realization through stepwise integration.

Distributed business process coordination: a functionally oriented infrastructure

Autores
Nunes, A; Ferreira, JJP; Mendonca, JM;

Publicação
INTERNATIONAL JOURNAL OF COMPUTER INTEGRATED MANUFACTURING

Abstract
This paper discusses some of the challenges presently found both in supply chain and in extended enterprise management. It also presents details of a Distributed Business Process Coordination Infrastructure that was used as a platform in the development of a software-based management system for a global supply chain in the garment sector. The pilot implementation that was undertaken allowed not only the validation of the proposed concepts but the testing of the integrated technological platform as well.

Building an e-marketplace on a peer-to-peer infrastructure

Autores

Publicação
INTERNATIONAL JOURNAL OF COMPUTER INTEGRATED MANUFACTURING

Abstract
Existing e-marketplaces, built on traditional client-server architectures, severely restrict the scope and dynamics of Business-to-Business (B2B) interactions. Peer-to-peer (P2P) architectures will provide far more decentralized infrastructures, while allowing a much wider range of business patterns to take place. On one hand, the interaction over a P2P network resembles the way real-world enterprises perform business with each other. On the other hand, a small set of simple services is enough to support complex business processes over a P2P infrastructure. Incidentally, most of the required technology is readily available, although it may be necessary to bring in an appropriate integration of different concepts. The paper discusses the implementation of essential services for P2P e-marketplaces, based on one of the leading P2P platforms, and illustrates its benefits by applying the P2P approach to a vendor of industrial equipment.

A modelling language for the design and execution of enterprise models in manufacturing

Autores
Santos, JPO; Ferreira, JJP; Mendonca, JM;

Publicação
INTERNATIONAL JOURNAL OF COMPUTER INTEGRATED MANUFACTURING

Abstract
This paper proposes an enterprise modelling language (EML) for model-based shop floor control. To introduce a new computer executable modelling language, two modelling frameworks were analysed, namely the CIMOSA and GERAM frameworks. This language covers the different life cycle phases of enterprise modelling (design, implementation and operation), allowing an easy and fast transition from each phase to the next. In the operation phase the models can be used to control and monitor (on-line) the enterprise resources behaviour. Section 3 presents an example of an operational model, based on the proposed EML, for real-time enterprise activity control. Despite the fact that the proposed modelling language does not intend to be a full CIMOSA compliant language, it could easily be a first step in that direction. Section 4 tries to validate this hypothesis by showing how a CIMOSA model (functional view), could be built based on the proposed EML.
