the portfolio is a perfect combination of stock or assets, which an investor buys them. the objective of the portfolio is to divide the investment risk among several shares. using non-parametric dea and dea-r methods can be of great significance in estimating portfolio. in the present paper, the efficient portfolio is estimated by using non-radial dea and dea-r models. by proposing non-radial m...

Selection of new projects is one of the major decision making activities in any company. Given a set of potential projects to invest, a subset which matches the company’s strategy and internal resources best has to be selected. In this paper, we propose a multicriteria model for portfolio selection of projects, where we take into consideration that each of the potential projects has several usu...

This paper develops a bi-objective portfolio selection problem that maximizes returns and minimizes a risk measure called conditional Drawdown (CDD). The drawdown measures include the maximal Drawdown and Average Drawdown as its limiting case. The CDD family of risk functional is similar to conditional value at Risk (CVaR). In this paper, the fuzzy method has been used to solve the bi-objec...

By optimizing its outsourcing strategy, a company faces the opportunity to lower the overall costs of its IT project portfolio. Without considering risk and diversification effects appropriately, companies make wrong decisions about how much of a project is reasonable to outsource. In this paper, we elaborate a model to identify a project’s optimal degree of outsourcing at a fixed price, consid...

Selecting the “best” project portfolio out of a given set of investment proposals is a common and often critical management issue. Decision-makers must regularly consider multiple objectives and often have little a priori preference information available to them. In this paper a new approach to prioritize project portfolio in an efficient and reliable way is presented. It is based on strategic ...

The problemof selection and the best option are themain subject of operation research science in decision-making theory. Selection is a process that scrutinizes and investigates several quantitative and qualitative, and most often incompatible, factors. One of the most fundamental management issues in multicriteria selection literature is the multicriteria adoption of the projects portfolio. In...

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...

Financial problems have been the subject of much research. A widely used approach in recent work on these problems is the use of fuzzy set theory, where fuzzy terms are used to model the uncertain environments. The purpose of this work is to combine the fuzzy analytic hierarchy process (AHP) with the portfolio selection problem. More specifically, the decision-making problem is to decide which ...
