Task-based visual analytics for interactive multiobjective optimization
2020
We study how visual interaction techniques considered in visual analytics can be utilized when implementing interactive multiobjective optimization methods, where a decision maker iteratively participates in the solution process. We want to benefit from previous research and avoid re-inventing ideas. Our aim is to widen awareness and increase the applicability of interactive methods for solving real-world problems. As a concrete approach, we introduce seven high-level tasks that are relevant for interactive methods. These high-level tasks are based on low-level tasks proposed in the visual analytics literature. In addition, we give an example on how the high-level tasks can be implemented a…
Visualizations for Decision Support in Scenario-based Multiobjective Optimization
2021
Reproducibility artifacts for: Babooshka Shavazipour, Manuel López-Ibáñez, and Kaisa Miettinen. Visualizations for Decision Support in Scenario-based Multiobjective Optimization. Information Sciences, 2021. doi:10.1016/j.ins.2021.07.025. Abstract: We address challenges of decision problems when managers need to optimize several conflicting objectives simultaneously under uncertainty. We propose visualization tools to support the solution of such scenario-based multiobjective optimization problems. Suitable graphical visualizations are necessary to support managers in understanding, evaluating, and comparing the performances of management decisions according to all objec…
Two ways to handle dependent uncertainties in multi-criteria decision problems☆
2009
Abstract We consider multi-criteria group decision-making problems, where the decision makers (DMs) want to identify their most preferred alternative(s) based on uncertain or inaccurate criteria measurements. In many real-life problems the uncertainties may be dependent. In this paper, we focus on multicriteria decision-making (MCDM) problems where the criteria and their uncertainties are computed using a stochastic simulation model. The model is based on decision variables and stochastic parameters with given distributions. The simulation model determines for the criteria a joint probability distribution, which quantifies the uncertainties and their dependencies. We present and compare two…
EXPLORING THE EFFECTS OF DISCUSSION AND TEXT PLANNING STRATEGIES TO ENHANCE AND ASSESS WRITTEN COMMUNICATION SKILLS
2016
A scuola come nella vita, le capacità di comunicazione scritta sono fondamentali. Queste abilità riguardano soprattutto la costruzione di testi per usi e scopi diversi, l’elaborazione efficace delle informazioni, l’uso corretto della forma linguistica. Scrivere significa conoscere le regole grammaticali ma soprattutto riflettere sulle situazioni e sui contesti specifici di realizzazione, considerare le funzioni linguistiche, gli scopi e i bisogni comunicativi. Sempre più spesso lo sviluppo tecnologico alimenta le difficoltà di bambini e ragazzi di produrre discorsi corretti, coerenti e logicamente organizzati. Per promuovere e valutare la competenza espressiva scritta (strutturazione logica…
Bio-ecological, phytosociological and conservation aspects of relictual and disjointed populations of Simethis mattiazzi (Vandelli) Sacc. (Xanthorrho…
2012
Two populations of Simethis mattiazzi (Xanthorrhoeaceae) were recently discovered in the Channel of Sicily – (1) Punta Bassana (Marettimo Island) and (2) Mount S. Giuliano (western Sicily) – at a considerable distance from the nearest stations hitherto known, located in southern Sardinia, the Pontine Islands Archipelago and Tunisia. The taxonomical and distributive aspects of this species are analysed to highlight the relictual and biogeographical significance of the disjointed and fragmentary nuclei distributed in several small islands of the Channel of Sicily, the Italian Peninsula and North Africa. Some morphological, biological, ecological and phytosociological aspects of the two new po…
Dexipm-Grapevine : a multicriteria assessment tool of the sustainability for grapevine farming systems
2015
The development of innovative farming systems to reach new goals of agricultural sustainability needs new methods for efficiency assessment. DEXiPM-Grapevine© is a multicriteria assessment tool for overall sustainability of grapevine farming systems adapted from DEXiPM arable crops (Pelzer et al, 2012). DEXiPM-Grapevine© was implemented during the European PURE Project 2012-2015 (Integrated Pest Management (IPM) solutions in agriculture) in order to assess and compare various innovative grapevine systems. This model includes 65 basic attributes describing the cropping system, which are then combined into 97 aggregated attributes, designed to assess the economic, social and environmental per…

CoSAC, un projet pour la conception de stratégies durables de gestion des adventices dans un contexte de changement (climat, pratiques agricoles, bio…
2016
The CoSAC project associates partners from research and development in order to (1) quantify and understand, with experiments, the effects of novel agricultural practices on weeds and the functioning of the agroecosystem, (2) design tools that predict the effect of agricultural techniques et pedoclimate on weed flora, (3) use these tools to design sustainable weed management strategies and to evaluate their performances in contexts of changing agricultural practices, climate, biodiversity, (4) facilitate the adoption of these novel strategies by farmers. We will present the first results of the project, e.g. the effect on weeds of cover crops during fallow or associated to a cash crop, the …
Simplification d’un modèle complexe pour le développement d’un modèle d’aide à la décision pour la gestion agroécologique de la flore adventice
2019
National audience; Afin de réduire l’utilisation d’herbicides, nous avons besoin de nouveaux outils pour aider à concevoir des stratégies de gestion des adventices économes en herbicides. Dans ce but, nous avons développé un Outil d'Aide à la Décision (OAD) pour la conception de systèmes de culture réconciliant protection des cultures et respect des écosystèmes. La démarche fait intervenir en parallèle le développement de la structure de l’outil en interaction avec les futurs utilisateurs (conseillers et agriculteurs) et une sim-plification du contenu biophysique du modèle FLORSYS concernant les impacts des systèmes de culture et des adventices. FLORSYS est une « parcelle virtuelle », où so…
