Argumentation graphs with constraint-based reasoning for collaborative expertise
2018
International audience; Collaborative processes are very important in telemedicine domain since they allow for making right decisions in complex situations with multidisciplinary staff. When modelling these collaborative processes, some inconsistencies can appear. In semantic modelling (conceptual graphs), these inconsistencies are verified using constraints. In this work, collaborative processes are represented using an argumentation system modelled in a conceptual graph formalism where inconsistencies could be particular bad attack relation between arguments. To overcome these inconsistencies, two solutions are proposed. The first one is to weight the arguments evolving in the argumentati…
EU Experts’ Attitude Towards Use of GMO in Food and Feed and Other Industries
2014
Abstract This article examines European Union (EU) experts’ attitude towards use of genetically modified organisms (GMO) in food, feed and other industries with an eye to developing a general model of EU experts’ opinion formation in this area. The gene engineering has seen rapid advances in recent years with a host of new applications in medicine, agriculture, and related fields. Taking into account the history of consumption, social, economic, cultural and other aspects and the risk perception in general regarding these products the consumers’ willingness to buy genetically modified (GM) products varies from country to country as well as attitude of the experts involved in the decision ma…
Modelling the energy costs of the wastewater treatment process: The influence of the aging factor.
2017
Wastewater treatment plants (WWTPs) are aging and its effects on the process are more evident as time goes by. Due to the deterioration of the facilities, the efficiency of the treatment process decreases gradually. Within this framework, this paper proves the increase in the energy consumption of the WWTPs with time, and finds differences among facilities size. Accordingly, the paper aims to develop a dynamic energy cost function capable of predicting the energy cost of the process in the future. The time variable is used to introduce the aging effects on the energy cost estimation in order to increase the accuracy of the estimation. For this purpose, the evolution of energy costs will be …
Understanding the consumption of plant-based meat alternatives and the role of health-related aspects. A study of the Italian market
2023
One possible solution to address some of the current health and environmental challenges we are facing is to choose plant-based meat alternatives (PBMAs). However, from the literature, the role of PBMA products in the consumer’s diet and whether they are a substitute for red meat consumption or if they only represent an enrichment function is not clear. Moreover, little is known about how health-related aspects affect consumer choices. This study tries to understand the role of PBMAs in consumption habits and the effects of health-related aspects in PBMA consumption. The results show that PBMA consumption occurs in substitution to red meat, and it is associated mainly with healthy and susta…
The cost-effectiveness of neonatal versus prenatal screening for congenital toxoplasmosis
2019
BackgroundCongenital Toxoplasmosis (CT) can have severe consequences. France, Austria, and Slovenia have prenatal screening programs whereas some other countries are considering universal screening to reduce congenital transmission and severity of infection in children. The efficiency of such programs is debated increasingly as seroprevalence among pregnant women and incidence of congenital toxoplasmosis show a steady decrease. In addition, uncertainty remains regarding the effectiveness of pre- and postnatal treatments.MethodTo identify cost-effective strategies, prenatal and neonatal screenings were compared using a decision-analytic model based on French guidelines and current knowledge …
Reference point approach for multiple decision makers
2005
We consider multiple criteria decision-making problems where a group of decision-makers wants to find the most preferred solution from a discrete set of alternatives. We develop a method that uses achievement functions for charting subsets of reference points that would support a certain alternative to be the most preferred one. The resulting descriptive information is provided to the decision-makers in the form of reference acceptability indices and central reference points for each decision alternative. Then, the decision-makers can compare this information with their own preferences. We demonstrate the use of the method using a strategic multiple criteria decision model for an electricit…
Determining the implementation order of a general plan by using a multicriteria method
1998
We describe a real-life application of a new multicriteria method in the context of assisting the decision-making for a general plan in the municipality of Kirkkonummi in Uusimaa, Finland. At the time our group started working on the problem, a proposal for an overall plan had already been completed, but the order in which different regional parts of the plan should be implemented needed to be considered based on the environmental impact assessment (EIA) procedure. The EIA procedure generated a large amount of data about the different impacts of the alternatives. For this group decision making problem we developed the SMAA-3 decision support method which does not require any explicit prefer…
Affect, Uncertainty, and Decision-Making
2016
International audience; Decision-making is a complex cognitive process of selecting an action among various alternatives. Everyday life is full of situations calling for multiple decisions: living somewhere, moving home, choosing a route, changing route are all decisions that determine our life setting and way of life. These decisions may have a limited impact or over the longer term may cause slight inconvenience, a fleeting feeling of well-being or deep unease, or possibly even unbearable anxiety.
Untangling knowledge fields and knowledge dynamics within the decision-making process
2020
PurposeThe purpose of this paper is to analyse the influences of different types of knowledge and their inherent dynamics on the effectiveness of the decision-making (DM) process. Knowledge dynamics (KD) is envisioned through the lens of the knowledge fields theory while effective DM process is objectivised via organisational appreciation and reward, higher business performance, sustainable partnerships and managerial satisfaction with previous achievements.Design/methodology/approachA questionnaire-based survey was conducted with 275 middle managers from companies operating in the business consulting field. The conceptual and structural model was tested using the partial least squares stru…
Digital Transformation in Maintenance Management
2022
The relationship between technology and maintenance is mutually beneficial since technology is continuously improving with consequent substantial advancements in the field of maintenance. Maintenance management may be effectively modernized through digitalization. Developing advanced technologies promotes indeed the possibility of maintaining a competitive and long-term position in this field. Digitalization is consistently transforming organizations by allowing them to use suitable technologies for collecting data automatically. Various equipment and components are nowadays capable of collecting their operating data over an extended period, which may yield a plethora of intriguing insights…
