Pattern Reification as the Basis for Description-Driven Systems

One of the main factors driving object-oriented software development for information systems is the requirement for systems to be tolerant to change. To address this issue in designing systems, this paper proposes a pattern-based, object-oriented, description-driven system (DDS) architecture as an extension to the standard UML four-layer meta-model. A DDS architecture is proposed in which aspects of both static and dynamic systems behavior can be captured via descriptive models and meta-models. The proposed architecture embodies four main elements - firstly, the adoption of a multi-layered meta-modeling architecture and reflective meta-level architecture, secondly the identification of four data modeling relationships that can be made explicit such that they can be modified dynamically, thirdly the identification of five design patterns which have emerged from practice and have proved essential in providing reusable building blocks for data management, and fourthly the encoding of the structural properties of the five design patterns by means of one fundamental pattern, the Graph pattern. A practical example of this philosophy, the CRISTAL project, is used to demonstrate the use of description-driven data objects to handle system evolution.Comment: 20 pages, 10 figure

The Human Capital-Intensive Firm and Coordination: Redefined Integration and Disintegration

The aim of this paper is to reconsider the link between integration and disintegration. We argue that the conception of this link depends on the way one defines the firm and its coordinating role. We focus on studying the human capital-intensive firm. We explain that coordination by this kind of firms consists in coordinating productive tasks. The role of the firm is to coordinate the specialization of complementary resources and the division of labour. We show that integration and disintegration must be differentiated by the tools they give to the firm to effectively govern productive assets.Specific human capital; coordination; disintegration; integration; boudaries of the firm

Organisational Abstractions for the Analysis and Design of Multi-Agent Systems

The architecture of a multi-agent system can naturally be viewed as a computational organisation. For this reason, we believe organisational abstractions should play a central role in the analysis and design of such systems. To this end, the concepts of agent roles and role models are increasingly being used to specify and design multi-agent systems. However, this is not the full picture. In this paper we introduce three additional organisational concepts - organisational rules, organisational structures, and organisational patterns - that we believe are necessary for the complete specification of computational organisations. We view the introduction of these concepts as a step towards a comprehensive methodology for agent-oriented systems

OperA/ALIVE/OperettA

Comprehensive models for organizations must, on the one hand, be able to specify global goals and requirements but, on the other hand, cannot assume that particular actors will always act according to the needs and expectations of the system design. Concepts as organizational rules (Zambonelli 2002), norms and institutions (Dignum and Dignum 2001; Esteva et al. 2002), and social structures (Parunak and Odell 2002) arise from the idea that the effective engineering of organizations needs high-level, actor-independent concepts and abstractions that explicitly define the organization in which agents live (Zambonelli 2002).Peer ReviewedPostprint (author's final draft

Operational design co-ordination : an agent based approach

Operational design co-ordination has been identified as the basis for an approach to engineering design management that is more comprehensive than those that currently exist. As such, an integrated and holistic approach to operational design co-ordination has been developed that enables design to be managed in a coherent, appropriate and timely manner. Furthermore, the approach has been implemented within an agent-based software system, called the Design Co-ordination System, which has been applied to an industrial case study involving the computational design analysis of turbine blades. This application demonstrates that managing and adjusting in real-time in an operationally co-ordinated manner enables reductions in the time taken to complete the turbine blade design process to be achieved

Formalization of the partnering structure for networked businesses

Rapidly changing market demands and increasing competitive pressure cause many businesses implement changes to the way they conduct business. One of these changes is the decision to collaborate with other businesses, forming what we call a 'networked business'. Networked businesses are formed by different organizations working together to reach a common goal. For the participating organizations in a networked business to be able to promptly react to their customers' needs, they must set up as cornerstone a well-defined collaborative partnering structure. In this report we discuss the partnering structure of networked businesses and present a framework for its formalization. Using a case study, we illustrate that existing approaches for value modeling, roles specification, and responsibilities definition can be used successfully if employed in a unifying way to address this structure concept

INDUSTRIAL TRANSFORMATION IN THE AFTERMATH OF THE CRISIS: An Empirical Analysis of Industrial Policies in France, Germany, Spain and the United Kingdom. CES Open Forum Series 2018-2019, 2019

This paper gauges the forces and structures that shape economic transformation through an analysis of industrial polices in four European economies since the 2008 crisis: France, Germany, Spain and the United Kingdom. We argue that differences across recent European industrial policies respond to variations in national historical and institutional legacies; the characteristics of productive structures and the capabilities of the state. Pathdependency shapes views regarding the acceptable role of the state, although institutional legacies need to be balanced against historical institutional consistency and the intensity of the crisis. The characteristics of industry in terms of size, specialization, and position in the global division of labor affect preferences for framework versus sector-specific policies and the ambitiousness of goals. Finally, the state’s coordination capacity is essential to the design and efficient implementation of interrelated actions across multiple areas whereas financial capacity establishes commitment, signals priorities, and determines the feasibility of forward-looking projects

Neofunctionalism revisited : integration theory and varieties of outcomes in the Eurocrisis

The Euro crisis has produced a plethora of new institutions, policies, and projects to reform the Euro Area. This paper offers a theoretical and empirical contribution in the study of the New Economic Governance. By building on insights from classical Neofunctionalism and Liberal Intergovernmentalism, the paper revisits the static component of Philippe Schmitter's 'Neo-Neofunctionalist' framework. Static Neo-Neofunctionalism is then applied as a means to provide a systemic interpretation of crisis-led integration in the Euro crisis. The large majority of episodes of crisis-led integration in the 2011-2016 years is included in the analysis. In assessing Neo-Neofunctionalist expectations on the New Economic Governance, the paper matches analysis of legal documents with the results of a dedicated Expert Survey on the EMU governance fielded in October 2018
