Business Analytics

Atualmente o setor segurador enfrenta diversas dificuldades, não só pela crise económica internacional e pelo mercado cada vez mais competitivo, como também pelas exigências impostas pela entidade reguladora - Instituto de Seguros de Portugal (ISP). Desta forma, apenas as seguradoras que consigam monitorizar os seus riscos, adequando os prémios praticados, conseguirão sobreviver. A forma de o fazer é através de uma adequada tarifação. Neste contexto de elevada instabilidade, as plataformas de Business Intelligence (BI) têm vindo a desempenhar um papel cada vez mais importante no processo de tomada de decisão, nomeadamente, o Business Analytics (BA), que proporciona os métodos e ferramentas de análise. O objetivo deste projeto é desenvolver um protótipo de solução de BA que forneça os inputs necessários ao processo de tomada de decisão, através da monitorização da tarifa em vigor e da simulação do impacto da introdução de uma nova tarifa. A solução desenvolvida apenas abrange a tarifa de responsabilidade civil automóvel (RCA). Ao nível das ferramentas analíticas, o foco foi a análise visual, nomeadamente a construção de dashboards, onde se inclui a análise de sensibilidade ou what-if analysis (WIF). A motivação para o desenvolvimento deste projeto foi a constatação de inexistência de soluções para este fim nos ambientes profissionais em que estive envolvido.

Indoor location-based analytics systems: Portuguese market compettive assessment and entry procing strategy of BIPs' technology in Sonae Sierra Shopping malls stores

This project attempts to provide an in-depth competitive assessment of the Portuguese indoor location-based analytics market, and to elaborate an entry-pricing strategy for Business Intelligence Positioning System (BIPS) implementation in Portuguese shopping centre stores. The role of industry forces and company’s organizational resources platform to sustain company’s competitive advantage was explored. A customer value-based pricing approach was adopted to assess BIPS value to retailers and maximize Sonae Sierra profitability. The exploratory quantitative research found that there is a market opportunity to explore every store area types with tailored proposals, and to set higher-than-tested membership fees to allow a rapid ROI, concluding there are propitious conditions for Sierra to succeed in BIPS store’s business model in Portugal.

Graph usage in financial reports: Evidence from Portuguese listed companies

When assessing investment options, investors focus on the graphs of annual reports, despite lack of auditing. If poorly constructed, graphs distort perceptions and lead to inaccurate decisions. This study examines graph usage in all the companies listed on Euronext Lisbon in 2013. The findings suggest that graphs are common in the annual reports of Portuguese companies and that, while there is no evidence of Selectivity Distortion, both Measurement and Orientation Distortions are pervasive. The study recommends the auditing of financial graphs, and urges preparers and users of annual reports to be wary of the possibility of graph distortion.

Graph usage in annual reports, evidence from Norwegian listed companies

As investors and other users of annual reports often focus their attention on graphs, it is important that they portray accurate and reliable information. However, previous studies show that graphs often distort information and mislead users. This study analyses graph usage in annual reports from the 52 most traded Norwegian companies. The findings suggest that Norwegian companies commonly use graphs, and that the graph distortions, presentational enhancement and measurement distortion, are present. No evidence of selectivity was found. This study recommends development of guidelines for graphical disclosure, and advises preparers and users of annual reports to be aware of misleading graphs.

Specification of software architecture reconfiguration

In the past years, Software Architecture has attracted increased attention by academia and industry as the unifying concept to structure the design of complex systems. One particular research area deals with the possibility of reconfiguring architectures to adapt the systems they describe to new requirements. Reconfiguration amounts to adding and removing components and connections, and may have to occur without stopping the execution of the system being reconfigured. This work contributes to the formal description of such a process. Taking as a premise that a single formalism hardly ever satisfies all requirements in every situation, we present three approaches, each one with its own assumptions about the systems it can be applied to and with different advantages and disadvantages. Each approach is based on work of other researchers and has the aesthetic concern of changing as little as possible the original formalism, keeping its spirit. The first approach shows how a given reconfiguration can be specified in the same manner as the system it is applied to and in a way to be efficiently executed. The second approach explores the Chemical Abstract Machine, a formalism for rewriting multisets of terms, to describe architectures, computations, and reconfigurations in a uniform way. The last approach uses a UNITY-like parallel programming design language to describe computations, represents architectures by diagrams in the sense of Category Theory, and specifies reconfigurations by graph transformation rules.
