Nom 2.0: innovative network operations and management for business agility [technology leaders forum]

Faced with growing fierce competitive pressure on all fronts and market saturation, traditional telecommunication operators are now struggling to find the breakthrough approach by which they may successfully reshape their role from network service providers to multimedia service providers. They are re-examining their voice-centric business models and deploying next-generation networks (NGN) for QoS-guaranteed delivery of multimedia quadruple play services (QPSs). To cost effectively realize these paradigm shifts, the existing ";stability-oriented"; network operations and management infrastructure and processes should be migrated into ";service-oriented"; and ";business-driven"; network operations and management within the context of today's multimedia and converged business environments. In this article, I'd like to introduce Network Operations and Management 2.0 (NOM 2.0), which is an innovative next generation operations and management paradigm for telephone company business agility and customer value creation. KT recently proposed Telco 2.0 [1], a new role and business model in the IP world to create customer value. NOM 2.0 is a key component needed to realize the Telco 2.0 goals. Telcos need to transform their operations and management framework into a human-centric and highly intelligent and automated one, and become the market leader by providing an agile operation and management framework within ever-changing operations and business environments. I will describe what NOM 2.0 is and how it is being realized in my company, KT.

Ambient intelligence technologies in support of shipping markets’ operations

The Intelligent Maritime Environment (i-MARE) framework and technological platform we introduce in our paper conceptualize an innovative, collaborative and context-aware network business model for cargo shipping. The i-MARE framework considers ambient-intelligence technologies, in particular an ontology-derived and web semantics based interoperability framework and application modules for key shipping process areas, namely the maritime regulations-rules compliance and port operations support. We explain how the improvement of the later operations can be realized in terms of the proposed technological platform towards the effective matching of individual companies’ capabilities and needs with market demands for cargo shipping. Whereas cargo shipping refers to a number of different markets, our framework is generic and adaptable to the requirements of particular sectors, for instance ocean bulk shipping or short sea container shipping. The framework presented is proposed for testing and application in the maritime sector, whereas in our paper we examine, as a proof of concept, short sea shipping business cases and a normative modelling and architectural solution.

Operational risk analysis in business processes

The operational continuity of a business process is an important performance indicator that contributes to the perceived quality of service delivery, hence it is important to understand and monitor the underlying issues that can affect the performance of the process. These issues might have been foreseen at the beginning of the process design and deployment phase, or might have emerged during the execution of the process, and must be viewed as risk threats to the business process. In most cases risk is only considered from the project management angle or from financial, market, insurance and other general business perspective. Operational risk at service provision level receives little attention and thus there is a need to develop methodologies and tools to identify and analyse business operational risks. The authors concentrate on operational risk for business process management by introducing a novel way for applying risk assessment frameworks at the process activity level. The paper briefly reviews existing risk frameworks and selects the COSO framework as the most appropriate for business processes. This framework is modified in order to address and evaluate the main elements of business processes. It defines a statistical approach towards operational risk assessment by quantifying risk factors in each activity within a business process for service provision. A risk forecast is produced for each activity, and for the whole process, to model associated uncertainties and to contribute in identifying the risk factors that affect the business process objectives. To demonstrate the framework, it is applied to a hypothetical process involving setting up a network service. These results help to advise on which risk factors need higher attention in order to achieve successful process fulfilment.

Softwareentwicklung mit Application Frameworks

Application frameworks define for an application domain general interrelations between a set of abstract classes. These abstract classes form already a semi-complete solution for applications in a domain. To realize a concrete system some classes are derived to formulate application-dependent details and heuristics. This is explained by means of the Déjà Vu scheduling framework.     

Information-theoretic upper and lower bounds for statistical estimation

In this paper, we establish upper and lower bounds for some statistical estimation problems through concise information-theoretic arguments. Our upper bound analysis is based on a simple yet general inequality which we call the information exponential inequality. We show that this inequality naturally leads to a general randomized estimation method, for which performance upper bounds can be obtained. The lower bounds, applicable for all statistical estimators, are obtained by original applications of some well known information-theoretic inequalities, and approximately match the obtained upper bounds for various important problems. Moreover, our framework can be regarded as a natural generalization of the standard minimax framework, in that we allow the performance of the estimator to vary for different possible underlying distributions according to a predefined prior
