The portfolio construction problem usually has been viewed in the framework of risk-return trade-off. Using deterministic and stochastic portfolio models used to solve the problem lead to unrealistic results as both the expected return rate and the risk are vague. Moreover, the decision maker frequently deals with insufficient data when selecting a portfolio. Using fuzzy models allows removal o...

How is it possible to derive the superior IT investment portfolio? One main identified research objective in IT portfolio management (ITPM) is to manage a set of IT assets, similar to manage a financial portfolio to attain the superior return and risk. Among various IT assets, the investment in IT project is particularly critical. In finance, the concept of portfolio selectivity generally refer...

Data warehouses are characterized in general by heterogeneous data sources providing information with different levels of quality. In such environments many data quality approaches address the importance of defining the term “data quality” by a set of dimensions and providing according metrics. The benefit is the additional quality information during the analytical processing of the data. In th...

Background of the situation This project came about because NASA needed an independent cost, schedule and risk assessment of a proposed system. This proposed system was an update to an existing system, which was primarily a hardware system with a small amount of software. The proposed configuration used some of the existing hardware, but some of the hardware would be modified while other hardwa...

This paper discusses and analyzes risk measure properties in order to understand how a risk measure has to be used to optimize the investor’s portfolio choices. In particular, we distinguish between two admissible classes of risk measures proposed in the portfolio literature: safety risk measures and dispersion measures. We study and describe how the risk could depend on other distributional pa...

Portfolio optimization requires the minimal risk with certain expected return. The risk structure of securities, such as their exposure to countries, industrial sectors, or commodity/factor, have to be characterized, and then the optimal weights of securities in a portfolio can be determined to minimize the exposure of the portfolio to any specific risk factor. Typically, the risk factors are n...
