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…
A weighted logistic regression for conjoint analysis and Kansei engineering
2007
Customer needs for emotional satisfaction are increasingly being considered by product and service designers. While several existing methods such as conjoint analysis (CA), Kano model and quality function deployment support the translation of customer requirements into technical specifications, researchers are now working to develop methods aimed at integrating affective aspects into product design. Kansei engineering (KE) is a design philosophy that considers customer perceptions and emotions by adopting a multi-disciplinary approach. CA is a useful tool within a KE project. This article presents a methodology for conducting a KE project in early development phases. This methodology is bas…
Providing timely quality care after-hours: Perceptions of a hospital model of care
2019
Abstract Background Nurses working night shift are key-players in the acute care team, however, their work environment has been characterised by suboptimal leadership, communication inadequacies, limited resources, and a lack of adequate support. Aim The aim of this study was to investigate nurses' perceptions of the Hospital at Night Team, a nursing model of care implemented to provide timely quality nursing care after-hours. Methods The study used a descriptive design. Five focus groups were conducted, with a total of 34 nurses from 14 wards across a 600+ bed tertiary referral teaching hospital in Melbourne, Australia, one year after the Hospital at Night Team implementation. Focus group …
Inspection Policies in Service of Fatigued Aircraft Structures
2011
Fatigue is one of the most important problems of aircraft arising from their nature as multiple-component structures, subjected to random dynamic loads. For guaranteeing safety, the structural life ceiling limits of the fleet aircraft are defined from three distinct approaches: Safe-Life, Fail-Safe, and Damage Tolerance approaches. The common objectives to define fleet aircraft lives by the three approaches are to ensure safety while at the same time reducing total ownership costs. In this paper, the damage tolerance approach is considered and the focus is on the inspection scheme with decreasing intervals between inspections. The paper proposes an analysis methodology to determine appropri…
The Rail Quality Index as an Indicator of the “Global Comfort” in Optimizing Safety, Quality and Efficiency in Railway Rails
2012
AbstractThe proposed model uses the stochastic dynamic programming and in particular Markov decision processes applied to the Rail Quality Index (RQI - Italian Indice di Qualità del Binario, IQB).By performing the integrated analysis of the classes of variables which characterize the overall service quality (in terms of comfort and safety), the proposed mathematical approach allows to find the solutions to the decision-making process in function of the probability of deterioration of the state variables of the infrastructure over time and of the flow of available resources.
On the packing sums of pairs
1993
Abstract This paper is concerned with the determination of the length of the largest interval of consecutive integers of the set hA k , where A k is a sequence of integers which is a B h -sequence.
Political Consumerism and Food Community Networks
2011
European society, with its steadily increased welfare levels, is not only concerned about food (safety, prices), but also on other aspects such as biodiversity loss, landscape degradation, pollution of water, soil and atmosphere. To a large extent these concerns can be translated into a wider concept named sustainable development defined as a normative concept by Morgan and Sonnino (2008). Sustainability in the food chain means approaching a new emerging vision of a sustainable agro-food system introducing an institutional dimension to take into account. Among different attempts to conjugate such concepts, there is one that is taking place in many Regions of Italy. In the last years spontan…
The Beauty of the Commons? Consumers Participation in Food Community Networks
2012
Why are consumers increasingly joining farmers to co-produce and transact sustainable foods world-wide? May these networks be a new tool to promote sustainable practices? As stated by Sandler (2010): “Longitudinal collective action environmental problems are likely to be effectively addressed only by an enormous number of individuals each making a nearly insignificant contribution to resolving them”. Consumers-farmers networks may serve this scope by inducing individual actors to change their preferences towards sustainable products. However participation in these networks is still not well understood. On one hand new institutional economics explains consumers joining farmers in creating a n…
Assessment of the Vegetation Parameters of Almond and Vine Plants for Designing a Compact Tractor
2018
The aim of this research is to assess the vegetation parameters of almond and vine plants, aimed at designing a compact tractor suitable for these orchards. The research is part of the Italian project TRACLAS, involving the Universities of Palermo, Milan, Bari, “Tuscia” of Viterbo and Agricultural Research and Economics - Research Unit for Agricultural Engineering (CREA-ING) of Treviglio (Bergamo). Based on the results of the surveys carried out in a sample of almond and vine farms, it was possible to define the vegetation parameters that will allow to design a very low and narrow tractor equipped with a fixed ROPS and suitable for these orchards.
