Disruption Management in Airline Operations Control – An Intelligent Agent-Based Approach

Operations control is one of the most important areas for an airline company. Through operations control mechanisms an airline company monitors all the flights checking if they follow the schedule that was previously defined by other areas of the company. Unfortunately, some problems may arise during this stage (Clausen et al., 2005). Those problems can be related with crewmembers, aircrafts and passengers. The Airline Operations Control Centre (AOCC) includes teams of experts specialized in solving the above problems under the supervision of an operation control manager. Each team has a specific goal contributing to the common and general goal of having the airline operation running under as few problems as possible. The process of solving these kinds of problems is known as Disruption Management (Kohl et al., 2004) or Operations Recovery

Market segmentation in behavioral perspective

A segmentation approach is presented using both traditional demographic segmentation bases (age, social class/occupation, and working status) and a segmentation by benefits sought. The benefits sought in this case are utilitarian and informational reinforcement, variables developed from the Behavioral Perspective Model (BPM). Using data from 1,847 consumers and from a total of 76,682 individual purchases, brand choice and price and reinforcement responsiveness were assessed for each segment across the UK cookie (biscuits) market. Building on previous work, the results suggest that the segmentation of brand choice using benefits sought is useful. This is especially the case alongside demographic variables. This article provides a theoretical and practical segmentation approach to both the behavioral psychology literature and the wider marketing segmentation literature

Consumer brand choice: Money allocation as a function of brand reinforcing attributes

Previous applications of the matching law to the analysis of consumer brand choice have shown that the amount of money spent purchasing a favorite brand tends to match the quantity bought of the favorite brand divided by the quantity bought of all other brands. Although these results suggest matching between spending and purchased quantity, branded goods differ qualitatively among themselves, rendering previous matching analyses incomplete. Consumer panel data containing information about more than 1,500 British consumers purchasing four grocery product categories (baked beans, biscuits, fruit juice, and yellow fats) during 52 weeks were analyzed. All the brands purchased were classified according to the level of informational and utilitarian reinforcement they were programmed to offer. An adaptation of the generalized matching law was adopted, in which the amount of money spent was a power function of the quantity bought, informational level of the brand bought, utilitarian level of the brand bought, and a measure of price promotion

Consumer Behaviour Analysis and Consumer Brand Choice

This is the SECOND of TWO linked articles on consumer behavioural analysis dealing with the Behavioural Perspective Model, which locates consumer behaviour at the intersection of the consumer’s learning history and the consumer situation. As an example of research inspired by the Model, this article presents investigations into consumers’ patterns of brand choice, showing how brand repertoires are formed and how brands are selected within those repertoires

Consumer Behaviour Analysis and the Behavioural Perspective Model

This is the FIRST of TWO linked articles on consumer behavioural analysis. Cognitive theories have dominated the field of consumer behaviour for the last few decades, however, an observed lack of consistency between attitudes and behaviour has suggested the need to investigate more thoroughly situational and behavioural variables. Consumer behaviour analysis can be viewed as an alternative theoretical approach that emphasizes situational variables and measures of behaviour. Within consumer behaviour analysis, the Behavioural Perspective Model (BPM) interprets consumer behaviour as occurring at the intersection of the individual’s learning history and the consumer setting, which signals utilitarian and informational consequences associated with consumption-related responses. Utilitarian consequences are mediated by the product or service and are related to its functional benefits. Informational consequences are social, mediated by other people, and are related to feedback upon consumers’ behaviour, such as social status and prestige

Consumer-based brand equity and brand performance

The relation between consumer-based brand equity and brand performance was investigated across 15 product categories in Brazil and the UK. Brand equity was conceptualized as related to the level of social benefit offered by each brand and was measured with a simple questionnaire that asked consumers to rate brands with respect to their familiarity and quality levels. These measures were then related to brand market share and revenue. Results showed that the relation between consumer-based brand equity and brand performance varies across product categories, indicating that products differ with respect to their level of brandability and suggesting ways to measure it

Consumer Behavior Analysis and Social Marketing: The Case of Environmental Conservation

Consumer behavior analysis represents one development within the behavior-analytic tradition of interpreting complex behavior, in which a specific conceptual framework has been proposed (i.e., the Behavioral Perspective Model). According to this model, consumer behavior occurs at the intersection of a consumer-behavior setting and an individual’s learning history of consumption and is a function of utilitarian (mediated by the product) and informational (mediated by other persons) consequences. The model has been useful in analyses of consumers’ brand choice and reactions to different settings. In the present paper, the model was applied to the interpretation of environmental deleterious behaviors (use of private transportation, consumption of domestic energy, waste disposal, and domestic consumption of water). This application pointed to specific marketing strategies that should be adopted to modify each of these operant classes

Chemical and Sensorial Characterization of Tropical Syrah Wines Produced at Different Altitudes in Northeast of Brazil

Over the years, viticulture has expanded to new regions outside the temperate zones, such as Northeast Brazil, India, Thailand, Myanmar, Vietnam, Bangladesh and Venezuela, characterized by the production of tropical wines. It is important for the productive sector to comprehend the effects of grapevine interaction with the characteristics of each new region on wines composition. In this study, the composition of wines of Syrah from two regions with different altitudes in Northeast Brazil were analyzed by different methodologies to characterize chemical compounds as sugar, acids, minerals, phenolics (anthocyanins, flavonols, stilbenes and condensed tannins) and the sensory profile. The wines of the Bahia region (1100 m of altitude) obtained high concentrations for chemical parameters related to color, monomeric anthocyanins, stilbenes and monomeric and oligomeric tannins. Wines of the low altitude region, Pernambuco (350 m of altitude) were characterized by higher concentrations of flavonols (kaempferol, isorhamnetin, quercetin and rutin) and polymerized tannins. The chemical composition of wines from the two studied regions was influenced by altitude. A trend towards higher concentrations in most for phenolic compounds analyzed was observed in wines from the higher altitude region during the two years of study. Regarding the sensory profile, fruity, floral, herbaceous and empyreumatic attributes aromatic obtained highest scores in wines of the 350 m altitude region, the other attributes were dependent on the year of harvest

Suppressing CMB Quadrupole with a Bounce from Contracting Phase to Inflation

Recent released WMAP data show a low value of quadrupole in the CMB temperature fluctuations, which confirms the early observations by COBE. In this paper, a scenario, in which a contracting phase is followed by an inflationary phase, is constructed. We calculate the perturbation spectrum and show that this scenario can provide a reasonable explanation for lower CMB anisotropies on large angular scales.Comment: 5 pages, 3 figure
