Surrogate-assisted multicriteria optimization: Complexities, prospective solutions, and business case

2017

Complexity in solving real-world multicriteria optimization problems often stems from the fact that complex, expensive, and/or time-consuming simulation tools or physical experiments are used to evaluate solutions to a problem. In such settings, it is common to use efficient computational models, often known as surrogates or metamodels, to approximate the outcome (objective or constraint function value) of a simulation or physical experiment. The presence of multiple objective functions poses an additional layer of complexity for surrogate-assisted optimization. For example, complexities may relate to the appropriate selection of metamodels for the individual objective functions, extensive …

Dal liceo all’università: un modello sperimentale di orientamento

2019

In questo articolo, sono presentati il quadro teorico, le ipotesi, il disegno sperimentale e le fasi di una ricerca appena iniziata in sei scuole superiori di Palermo. Questa ricerca ha lo scopo di ridurre negli studenti il divario tra le conoscenze acquisite alla fine degli studi liceali e quelle richieste all'inizio dei corsi universitari e rafforzare la capacità di formulare il proprio progetto di vita professionale. Si sperimenterà l’azione congiunta di tre tipi di interventi: la scrittura espressiva per prefigurare il proprio futuro formativo-professionale, il colloquio di orientamento per esercitare la propria capacità decisionali e la conduzione di seminari pomeridiani tenuti da un p…

Why Use Interactive Multi-Objective Optimization in Chemical Process Design?

2008

Problems in chemical engineering, like most real-world optimization problems, typically, have several conflicting performance criteria or objectives and they often are computationally demanding, which sets special requirements on the optimization methods used. In this chapter, we point out some shortcomings of some widely used basic methods of multi-objective optimization. As an alternative, we suggest using interactive approaches where the role of a decision maker or a designer is emphasized. Interactive multi-objective optimization has been shown to suit well for chemical process design problems because it takes the preferences of the decision maker into account in an iterative manner tha…

Analysis of a database to predict the result of allergy testing in vivo in patients with chronic nasal symptoms.

2014

Background This article uses the logistic regression model for diagnostic decision making in patients with chronic nasal symptoms. We studied the ability of the logistic regression model, obtained by the evaluation of a database, to detect patients with positive allergy skin-prick test (SPT) and patients with negative SPT. The model developed was validated using the data set obtained from another medical institution. Methods The analysis was performed using a database obtained from a questionnaire administered to the patients with nasal symptoms containing personal data, clinical data, and results of allergy testing (SPT). All variables found to be significantly different between patients w…

Using uncertain preferential information from stakeholders to assess the acceptability of alternative forest management plans

2017

In forest management planning, participatory planning processes are often encouraged as a means to acquire relevant information and to enhance the stakeholders' acceptability of alternative plans. This requires the aggregation of the stakeholders' preferences that can be done in a wide variety of manners. The aggregation process strives to reduce the information into a single set of preferences that simplifies the information and allows for the use of discrete decision support tools. Depending on how the preferences are aggregated, a wide range of plan rankings can emerge. Although this range of ranking complicates the issue of plan selection, it does highlight the uncertainty involved in a…

Contents and functions of dramatizations in team decision making

2017

This study examines the contents and functions of dramatizations in natural team decision making. Theoretically, the study employs symbolic convergence theory to understand decision making as a complex phenomenon constructed in symbolic communication. Observational meeting data and thematic interview data from an autonomous team in Finland were analyzed. A fantasy theme analysis and an inductive, rhetorical discourse analysis revealed three rhetorical visions and seven functions of dramatizations in the team’s decision making. Visions represented social, righteous, and pragmatic master analogues. The functions of dramatizations were legitimizing independent and current decisions, reinforci…

ISEBA – A Framework for IS Evolution Benefit Assessment

2005

Decisions regarding information system evolution strategy, including modernization or replacement, are economically significant. Selection of a proper method for analyzing potential options, acquisition of suitable metrics or follow-up data, and evaluation of the results are major challenges in the evolution strategy decision making. In order to address these challenges, a framework for Information System Evolution Benefit Assessment (ISEBA) was developed. ISEBA provides assistance in the selection of a benefit-evaluation method for the investment situation at hand. It is based on empirical research on industrial decision making and co-operation projects, and examination of existing researc…

Clean Agent Selection Approached by Fuzzy TOPSIS Decision-Making Method

2008

Abstract. It is well known that halons are ozone-depleting substances and their release into the atmosphere has contributed in the last decades to the reduction in the ozone layer. In consequence to the Montreal Protocol, an international agreement designed to gradually eliminate the use of such substances, fire protection industry researchers faced the challenge of finding effective solutions to replace halon extinguishers. This research aims to provide a method to support the decision maker in the selection of the most suitable extinguisher substance for a specific application. According to such framework, a set of quantitative and qualitative criteria has been established in the decision…
