Misure di agglomerazione spaziale nei Sistemi Locali del Lavoro siciliani
2009
Spatial agglomeration indicators in the Sicilian Local Labour Systems Objectives - This paper examines the links among productive specialization, variety of the economic environment and knowledge spillovers on the basis of the territorial analyses present in the current literature. With the aim of identifying localization benefits in a particular area, some aspects of business settling are compared with trends in the development of economic activities and, particularly, with agglomeration process of the firms. Methods and Results The empirical analysis will be carried out pointing to the dynamics of employment consequent to the effects of the externalities above mentioned. Employment data a…
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…
Engaged teams deliver better service performance in innovation climates
2016
Building on the interactionist approach and the consideration of service organizations as open-systems, this study examines the moderating role of team climate for innovation on the relationship between team engagement and service performance. The sample consisted of 599 customers, 344 boundary employees, and 86 supervisors nested in 86 teams from 60 hotels. Multilevel analyses showed significant positive direct relationships between team engagement and service quality indicators. We also found a consistent moderating role of climate for innovation on the association between team engagement and different service performance indicators (functional and relational service quality, overall sati…
UWSIO: Towards automatic orchestration for the deployment of 5G monitoring services from bare metal
2018
The next generation mobile networks 5G are currently being intensively developed and standardized globally, with commercial prototyping 5G connections already emerging. At the 5G system level, one of the Key Performance Indicators (KPIs) defining 5G is substantially reduced service creation time for 5G network operators and/or service providers to increase the system efficiency and thus reduce operational costs. In this work, we focus on realize this challenging KPI in terms of speedy creation of monitoring services for 5G operators from scratch (no operating system pre-installed). A new 5G infrastructure orchestrator UWSIO is proposed to achieve fully automated deployment of 5G monitoring …
Measuring the eco-efficiency of wastewater treatment plants under data uncertainty
2018
Abstract Eco-efficiency assessment is a useful tool for improving the sustainability of wastewater treatment plants (WWTPs). However, it is a complex task that requires the integration of several performance indicators into a single index. Data envelopment analysis (DEA) is established as a highly effective methodology for achieving this as it permits the integration of the service value, resource consumption and environmental impact variables as the desirable outputs, inputs and undesirable outputs, respectively. However, traditional DEA models omit uncertainties in the data that are likely to result in biased conclusions. This study pioneers the assessment of the eco-efficiency of WWTPs w…
Innovative public governance through cloud computing
2014
Purpose – The purpose of this paper is to identify and analyze challenges and to discuss proposed solutions for innovative public governance through cloud computing. Innovative technologies, such as federation of services and cloud computing, can greatly contribute to the provision of e-government services, through scaleable and flexible systems. Furthermore, they can facilitate in reducing costs and overcoming public information segmentation. Nonetheless, when public agencies use these technologies, they encounter several associated organizational and technical changes, as well as significant challenges. Design/methodology/approach – We followed a multidisciplinary perspective (social, be…
Assessing the quality of service to customers provided by water utilities: A synthetic index approach
2017
Abstract Currently, water and sewer companies face the challenge of improving their quality of service to customers (QSC). Performance indicators are essential to monitor and benchmark the QSC of water companies; however, individual indicators do not provide a holistic evaluation of the quality of water and sewer services provided to customers. This study proposes an innovative QSC index based on distance-function techniques that makes it possible to compare changes in the QSC of water companies among locations and temporal periods. A case study assesses changes in QSC for a sample of Chilean water and sewer companies from 2007 to 2014. The results show that in spite of the efforts made by …
A Set of Key Performance Indicators for Solar Heating and Cooling Systems
2017
The application of solar heating and cooling systems for building air-conditioning actually shows a significant potential of exploitation, particularly in sunny regions. The choice whether or not to apply such technologies in different climates should be based on the assessment of their energy/environmental, economic and social sustainability, as well as their technical characteristics as reliability, durability and energy efficiency. To support researchers and decision-makers in the selection of the best solar air-conditioning solution in a specific geographic and energy context, the paper proposes a set of technical, economic, energy/environmental and social key performance indicators. Th…
Toward solutions for energy efficiency
2020
Abstract The tariff setting for district heating (DH) services is a hard regulatory procedure. This chapter is devoted to development of the simple but sufficiently accurate methodology for fast and objective evaluation of the actual costs of DH to optimize the regulatory process and to set adequate tariffs on heat production and transmission. The developed methodology is based on the data sets of Latvian DH providers, but the methodological principles are applicable in another area too. Investigation of heat production drivers and following simulation revealed the key performance indicators (KPIs): fuel type and price. By usage of intelligent benchmarking data mining methods and mathematic…
Wine and quality. A cluster anlysis to assess certain representative aspects relating to the quality
2009
This research, in which the technique of Cluster Analysis is used, will provide information on how wine producers can evaluate certain characteristics (variables) of their product more widely associated as indicative of quality. The analysis identified homogeneous groups containing within them other, related variables, which can be considered similar. Those attributes which are by themselves most representative of the product's quality are also highlighted. Finally, the cluster analysis made it possible to comment on the behaviour of producers, and looking at how they seek to meet market expectations based on their knowledge of customer's habits in the buying and consuming of wine.
