Aggregators are considered to be a key enabling technology for harvesting power system services from distributed energy resources (DER). As a precondition for more widespread use of aggregators in power systems, methods for comparing and validating aggregator designs must be established. This paper proposes a functional reference architecture for aggregators to address this requirement.
Enterprises face the challenge of rapidly adapting to dynamic business environments. The traditional approach to process management is only partially appropriate to this new context, and calls for the advent of new, evolutionary business processes. This new approach attempts to address specific issues related to flexibility and adaptation such as design of easily adaptable processes, dynamic handling...
Business analytics has emerged in the past decade as a top concern for business executives world-wide, surpassing earlier top concerns such as supply chain management and total quality management. Business analysis techniques analyze operational data for a variety of purposes including prediction, planning, monitoring, and trouble-shooting. In this paper we focus on one type of analysis, monitoring...
Monitoring composition of web services is important to ensure provisioning of a valid business process. Most of the existing works on service monitoring focused either on QoS violations or service interactions during execution of services that are statically composed. However, dynamic composition of services wherein the services are discovered and composed at runtime based on user requirements and...
Online process mining techniques are increasingly used to provide operational support. In this work we describe tools to support distributed business processes which handle sensitive data and require a high level of security together with real-time validation. The techniques presented here have been specifically developed for real-time compliance checking of distributed processes in choreographies...
This research paper focuses on reengineering and optimization of energy consumption and other costs for large IT infrastructures, with support from EA software which is based on advanced use of IT Key Performance Indicators (KPIs) and powerful visualization solutions. Use of KPIs is crucial in achieving energy efficient, green IT, implementing these metrics allows the enterprise to determine areas...
We propose a lean design methodology for business models, which repeatedly design business-model hypotheses in researching manner, moreover, with which corporate businesses can create new business value utilizing IT. Both analyzing business value that IT creates, and designing business models which repeatedly provide the business value will be possible. We applied the proposed method onto IoT utilizing...
Integrated care is essential to meet the needs related to the ageing of the population. In particular, integrated care allows a holistic view of the patients and, therefore, a better care. This paper proposes a Platform of Services to develop complex applications of information management to support the integration of health care and social care.
Cyber security operations centre (CSOC) is an essential business control aimed to protect ICT systems and support an organisation's Cyber Defense Strategy. Its overarching purpose is to ensure that incidents are identified and managed to resolution swiftly, and to maintain safe & secure business operations and services for the organisation. A CSOC framework is proposed comprising Log Collection,...
This paper discusses the problems of design and implementation of complex set of interconnected online and offline planning, optimization and monitoring tools of Swiss Transmission System Operator Swissgrid. After analyzing the requirements and challenges of the system, the paper presents its realization concept, as well as implementation results and the future plans. Solution under discussion widely...
In this era of the emerging digitized, mobilized, and cloudified enterprises, the concept of the "compos able business" is the most critical piece which ties everything together. The digital enterprise is here, and its prime characteristic is that is essentially detaches and segregates existing businesses and reassembles them according to market demands. Every industry, from transportation...
Virtual Communities (VCs) are dominating our daily activities from different insights. Social, Business, Professional, Educational and many VCs are competing to conquer the cloud by targeting more audience through the services they provide. The diversity, magnitude and quality of provided services raise a new challenge for managing these services. Consequently, the success or failure of VCs depends...
A key feature of Cloud computing is its agility and flexibility to support the scalability needs of business solutions. Currently, the agility is only limited to the scalability of the compute, memory and storage. To improve an application's agility, we need to monitor & measure solution level metrics and associate the performance of the metrics to the business agility needs of the solution...
The Nujiang is one of the regions where debris flow disasters occur frequently. For a long time, debris flow disasters have caused serious losses of life and property, so strengthening and controling the management of debris flow disasters and predict and alert debris flow disasters has become one of the main tasks for constructing and protecting ecological environment. Based on WebGIS, Internet of...
This paper focuses on batch environment of an enterprise. We use various data sources such as dependency data, alert and ticket data, and run history data of the jobs in batch systems to build a model of batch operations. We enrich the model with various attributes derived by graph analysis of dependency data, time-series analysis of execution history of jobs, and text and statistical analysis of...
Cloud data centers are increasingly becoming the first choice for many Internet enterprises (especially medium-sized and small ones) to deploy their online application. However, scaling service availability autonomously is a critical issue for Internet applications. Surplus service supply may take a lot of unnecessary money and insufficient resources reserve will result in denial of service when meeting...
This paper describes novel methodologies for assessing benefits and impact creation in IST related research projects. The paper first includes a Verification & Validation (V&V) method developed for evaluating of Future Internet software components implementation in a multi-sectorial environment. The proposed approach is based on best of breed V&V methodologies characterized by a structured...
For enterprises, it is important to know how the IT infrastructure contributes to the business goals set. The COBIT IT governance framework provides a high-level view how this can be achieved. However, COBIT provides no machine-readable model that allows to refer to entities (processes, goals, actions, metrics etc.). In this paper, we present an approach to create a formal model for COBIT using an...
With the promise of low-cost access to flexible and elastic resources, enterprises are increasingly migrating their existing workloads into the Cloud. Yet, the heterogeneity of the workloads and existing configuration of legacy IT infrastructure make it challenging to enable a one-click, seamless migration process. There are multiple tools available for migrating servers based on their existing configurations...
