Strategy, networks and systems in the global translation services market

The globalisation of markets has led to an increased demand for language translation services that support and enable communication between economic partners. For example, technical documents, software systems, business documents and web sites all need to be translated into multiple languages for individual national markets, and the information that they contain changes periodically. This paper sets out a theoretical framework that describes the architectures of business processes within and between separate firms that are used to support the delivery and management of services. This is done by coordinating the fit between externally generated problem complexity, from customers, and the internally generated complexity of different potential network configuration solutions. The theoretical framework is an architecture of how complexity is generated and managed at the different structural levels and across the different processual stages of an industry. A case study of thebigword, a major international translation services company, illustrates how the framework is applied in practice. The case study analyses the implementation of an electronic market platform which enables the coordination of the different stakeholders involved in the translation services market. These stakeholders include translators, translation services companies and their clients in a global business network.     

Business Object Modeling, Validation, and Mediation for Integrating Heterogeneous Application Systems

When different business organizations come together to conduct a joint business in a virtual enterprise environment, their application systems need to have a convenient way to specify the services needed from other systems and to transfer data needed by these services. The transferred data needs to be validated and, in some cases, mediated to meet the constraints and data representation requirements of both the source and target application systems. Ideally, the validation and mediation tasks should be done outside of the legacy application systems so that these systems do not have to be modified. In this work, the Business Object Documents (BODs) introduced by the Open Applications Group (OAG) are used for specifying business operations and transferring data among application systems. We use an active object model to model BODs. The model captures not only the data attributes and methods associated with these business objects, but also events and rules for specifying and triggering the enforcement of attribute constraints and inter-attribute constraints and the activation of data mediation operations. The conceptual models of these BODs with their added semantics are used to generate entity classes, converters and skeletal programs needed for enforcing constraints and for converting data. These generated object classes and software components in Java constitute the platform-independent adapters through which heterogeneous application systems inter-operate over CORBA and RMI communication infrastructures. A distributed approach to data validation and mediation is used. It allows the generated code for validation and mediation to be distributed and processed at different sites, thus avoiding the potential network bottleneck of a centralized approach to the validation and mediation of business object documents.

Topological analysis of a two coupled evolving networks model for business systems

In multi-agent systems, the underlying networks are always dynamic and network topologies are always changing over time. Performance analyses of topologies are important for understanding the robustness of the system and also the effects of topology on the system efficiency and effectiveness. In this paper, we present an example of a real-world distributed agent system, a digital business ecosystem (DBE). It is modelled as a two coupled network system. The upper layer is the business network layer where business process between different business agents happen. The lower layer is the underlying P2P communication layer to support communications between the agents. Algorithms for multi-agent tasks negotiation and execution, interaction between agents and the underlying communication network, evolutionary network topology dynamics, are provided. These algorithms consider the two network layers evolving over time, with effects on each other. Through a comprehensive set of discrete event simulation, we investigate the effects of different evolutionary principles inspired by random graph and scale-free network in complex network theory on the topological properties and performance of the underlying network. We also find several rules to design a resilient and efficient P2P network.
