The present paper aimed at studying the current models of credit portfolio management. There are currently three types of models which consider the risk of credit portfolio: the structural models (Moody's KMV model, and Credit- Metrics model), the intensity models (the actuarial models) and the econometric models (the Macro-factors model). The development of these three types of models is based...

empirical studies show that there is stronger dependency between large losses than large profit in financial market, which undermine the performance of using symmetric distribution for modeling these asymmetric. that is why the assuming normal joint distribution of returns is not suitable because of considering the linier dependence, and can be lead to inappropriate estimate of var. copula theo...

Purpose – The aim of this article is to develop an understanding of the issues related to risk management in digital library projects as well as techniques for mitigating risk in these projects. Design/methodology/approach – Using evidence from other research in the area, this article outlines the major risk issues within a project and then defines a model for mitigating risk within a project. ...

Project Portfolio Management (PPM) is an essential component of an organisation’s strategic procedures, which requires attention of several factors to envisage a range of long-term outcomes to support strategic project portfolio decisions. To evaluate overall efficiency at the portfolio level, it is essential to identify the functionality of specific projects as well as to aggregate those findi...

The problem of portfolio selection in investment concerns with minimizing the risk for a prespecified level of return. In this paper, the constraint on the level of return is fuzzified and the technique of fuzzy evolutionary programming is employed to select an optimal portfolio of securities with low risk and with highly acceptable level of total return. Experimental results show the method is...

Risk management aims to discuss the probabilities and consequences of risks on the goals of a software project. In such projects, there are dependence relationships between risks, although they are not treated yet by standard risk management practices. This paper is concerned with the analysis of risk dependencies, where these risks are assessed when multiple project stakeholders are involved i...

markowitz, in his portfolio selection theory, stated that investors select their portfolios according to two criteria of risk and return. accordingly, he presented his mathematical model. one of the criticisms of this model is that while investors, practically, consider different criteria in forming their portfolios, it only considers the return mean and return standard deviation. liquidity is ...

Reducing corporate risk has long been a business strategy concern. Many scholars support diversification as a method to achieve risk reduction. Building on organisational portfolio analysis, we develop the concept of ‘desynchronicity’ as a complement to existing diversification theories about risk reduction. Organisational portfolio analysis views firms as portfolios of business units, suggesti...

Critical success and failure factors of software projects were extensively studied. However, software project risk management has rarely researched organizational risks even though most problems occur when the social aspects are not addressed. By employing the resistance to change theory, our paper develops an organizational risk diagnosing (ORD) framework in order to show how can organizationa...
