Managing relational capital for the sustainability of the energy sector in the social media

Various management models have been proposed for intangible business assets in this new digital era. However, these models do not consider the relationships between intangible assets in business management, or their effect. This work has two main objectives: first, to show the effect of intangi-ble assets as expressed in digital media related to energy brands; second, to demonstrate the rela-tionships between the emotions, experiences and attitudes of the audiences. To do so, a novel model of intangibles is proposed and applied to the energy sector using IBEX 35 data. In this sce-nario, we determine that users' experiences extracted from digital environments have significant relationships with one of the most important intangibles in the energy business, namely emotion.Vários modelos de gestão foram propostos para ativos de negócios intangíveis nesta nova era digital. No entanto, esses modelos não consideram as relações entre ativos intangíveis na gestão ou os seus efeitos. Este estudo tem dois objetivos principais: primeiro, mostrar o efeito dos ativos intangíveis expressos nos meios digitais relacionados com as marcas associadas ao setor económico da energia; segundo, demonstrar as relações entre as emoções, experiências e atitudes do público. Para esse efeito, é proposto um novo modelo de gestão de intangíveis aplicado ao setor de energia utilizando dados do IBEX 35. Nesse cenário, concluímos que as experiências dos utilizadores extraídas de ambientes digitais têm relacionamentos significativos com um dos intangíveis mais importantes no negócio de energia, ou seja, a emoção.info:eu-repo/semantics/publishedVersio

Combining user preferences and expert opinions: a criteria synergy-based model for decision making on the Web

Customers strongly base their e-commerce decisions on the opinions of others by checking reviews and ratings provided by other users. These assessments are overall opinions about the product or service, and it is not possible to establish why they perceive it as good or bad. To understand this “why”, it is necessary an expert’s analysis concerning the relevant factors of the product or service. Frequently, these two visions are not coincident and the best product for experts may not be the best one for users. For this reason, trustworthy decision-making methods that integrate the mentioned views are highly desirable. This article proposes a multi-criteria decision analysis model based on the integration of users’ preferences and experts’ opinions. It combines the majority’s opinion and criteria synergy to provide a unified perspective in order to support consumers’ ranking-based decisions in social media environments. At the same time, the model supplies useful information for managers about strengths and weaknesses of their product or service according to users’ experience and experts’ judgment. The aggregation processes and synergy criteria are modeled in order to obtain an adequate consensus mechanism. Finally, in order to test the proposed model, several simulations using hotel valuations are performed.Project UTN4058 of National Technological University (Argentine) Fellowship for Short Term Postdoctoral Stays at University of Malaga – International Campus of Excellence Andalucía Tec

Modelado de toma de decisión con coalición de criterios e información lingüistica

Cuando es necesario resumir en un único valor diferentes opiniones relacionadas a una situación particular, usualmente se recurre a un proceso de agregación, que consiste básicamente en determinar el valor apropiado que represente la opinión de la mayoría. La presente tesis extiende el uso del operador de mayoría MA-OWA proporcionando un mecanismo para priorizar las mayorías sin que las minorías sean descartadas muy rápidamente. A su vez, este modelo, aplicado en los Social Media, es enriquecido dando la posibilidad de proporcionar la importancia de los valores a agregar con otros criterios diferentes a la cardinalidad de los mismos. Adicionalmente, se implementa un modelo de toma de decisiones donde los criterios a evaluar pueden presentar algún tipo de interacción. En este ámbito, la integral discreta de Choquet es un operador de agregación definido en función de una medida difusa, que se comporta adecuadamente para modelar el fenómeno expuesto. Se presenta un método de construcción automático de la medida difusa asociada a la integral, tomando como base las apreciaciones de varios expertos con diferentes niveles de experticia. Se recurre a la utilización de información lingüística para expresar el grado y signo de la sinergia entre los criterios intervinientes. Finalmente, si bien los modelos diseñados se comportan adecuadamente en forma separada, su potencial aumenta si se los emplea en un modelo integrado de coaliciones (en dos niveles) en base a la opinión de la mayoría
