A privacy enhanced device access protocol for an IoT context

2013

In this paper, we present the case for a device authentication protocol that authenticates a device/service class rather than an individual device. The devices in question are providing services available to the public. The proposed protocol is an online protocol, and it uses a pseudo-random temporary identity scheme to provide user privacy. This allows the Internet-of-Things device to have full assurance of the user, with respect to the request service, while permitting the user to remain anonymous with respect to the device. The user can then enjoy identity and location privacy in addition to untraceability with respect to device access. Copyright © 2013 John Wiley & Sons, Ltd.

A hybrid approach to semantic web services matchmaking

2008

AbstractDeploying the semantics embedded in web services is a mandatory step in the automation of discovery, invocation and composition activities. The semantic annotation is the “add-on” to cope with the actual interoperability limitations and to assure a valid support to the interpretation of services capabilities. Nevertheless many issues have to be reached to support semantics in the web services and to guarantee accurate functionality descriptions. Early efforts address automatic matchmaking tasks, in order to find eligible advertised services which appropriately meet the consumer’s demand. In the most of approaches, this activity is often entrusted to software agents, able to drive re…

A decision support system to assure high-performance maintenance service

2020

PurposeThis study aims to propose a decision support system (DSS) for maintenance management of a service system, namely, a street cleaning service vehicle. Referring to the information flow management, the blockchain technology is integrated in the proposed DSS to assure data transparency and security.Design/methodology/approachThe DSS is designed to efficiently handle the data acquired by the network of sensors installed on selected system components and to support the maintenance management. The DSS supports the decision makers to select a subset of indicators (KPIs) by means of the DEcision-MAaking Trial and Evaluation Laboratory method and to monitor the efficiency of performed prevent…

Digital Business Value Creation with Robotic Process Automation (RPA) in Northern and Central Europe

2018

In the rapidly changing global economy, robotics process automation (rpa) became one of the most important and fastest growing concepts. Digital value co-creation within service businesses and networks, sets value for end customer experience within more efficient operations, focusing on core business development with the use of modern technology. This pilot study approaches the topic from the practical perspective, presenting the results of empirical work conducted with experts working at the Intelligent Automation unit at one of the leading Nordic providers of financial and accounting services. It is examining the RPA transformation from the perspective of its impact on resourcing, operati…

A combined fuzzy-SEM evaluation approach to identify the key drivers of the academic library service quality in the digital technology era: An empiri…

2017

A conceptual model of the Academic Library (AL) service quality is hypothesized in the present article, and then validated and analyzed by a novel evaluation approach. Specifically, the conceptual model integrates the fundamental attributes of the canonical AL service together with those more relevant of the new and widely considered AL Electronic Service (e-services). As concerns the evaluation approach, it incorporates the Fuzzy Sets Theory (FST) so as to deal with the students' uncertainty over their own judgments on the AL service quality and a Structural Equation Model (SEM) to validate the conceptual model and to determine the key drivers of the AL service quality. The effectiveness o…

Analysis of Open Innovation Intermediaries Platforms by Considering the Smart Service System Perspective

2015

Abstract Open Innovation and Services Science are two distinct paradigms that share some principles 0. While some attempts to investigate open innovation according to a service science perspective exist, there is currently a gap with regards to the analysis of intermediaries of open innovation according to a service science perspective and even more regarding to recent trends about smart service system. This paper aims to fill this gap and, to this purpose, we present two interesting and original results. After an analysis of the key features of Open Innovation Intermediaries, we discuss a characterization of these intermediaries as service systems by mapping their features on the ten funda…

Design and optimisation of an innovative two-hub-and-spoke network for the Mediterranean short-sea-shipping market

2020

Abstract Short Sea Shipping (SSS) is generally considered as a privileged transport mode in terms of reducing road congestion and related external costs. In the last two decades, SSS has attracted a lot of attention in the European Union, where it is also regarded as a key factor for economic and social cohesion between countries. In this regard, the present study proposes a new network design that aims at improving and increasing freight traffic between the north-western and the south-eastern shores of the Mediterranean Basin. The proposed model, designed for Ro-Ro (Roll-on Roll-off) freight transport, tries to overcome the limits of the existing multi-port-calling services through an inno…

Predicting service request in support centers based on nonlinear dynamics, ARMA modeling and neural networks

2008

In this paper, we present the use of different mathematical models to forecast service requests in support centers (SCs). A successful prediction of service request can help in the efficient management of both human and technological resources that are used to solve these eventualities. A nonlinear analysis of the time series indicates the convenience of nonlinear modeling. Neural models based on the time delay neural network (TDNN) are benchmarked with classical models, such as auto-regressive moving average (ARMA) models. Models achieved high values for the correlation coefficient between the desired signal and that predicted by the models (values between 0.88 and 0.97 were obtained in th…

Towards Concrete Syntax Based Find for Graphical Domain Specific Languages

2019

One of the main reasons why Model-Driven Engineering (MDE) technologies including Domain-specific modelling languages (DSML) have not reached the expected acceptance in the industry is a poor tool support. One of the features with a limited support even in commercial modelling tools is search (find). Typically, MDE tools support only a simple keyword-based textual search functionality. The same is true for the tools built using Domain-specific language (DSL) tool definition frameworks. It is proposed to provide the concrete syntax-based find functionality as a service of a DSL tool definition framework. The find diagrams are defined in a concrete syntax of a DSL. A definition of a DSL is us…
