A common problem faced by organizations is how to select and schedule an optimal portfolio of projects subject various constraints, such as a limited budget. This known the project selection scheduling (PPSSP). Despite widespread nature this problem, no existing model adequately addresses sufficient set characteristics that arise in real-world problems. One contribution article proposal novel, ...

in traditional portfolio selection model coefficients often are certain and deterministic, but in real world these coefficients are probabilistic. so decision maker cannot estimate them exactly. financial optimization is one of the most attractive areas in decision under uncertainty. in the portfolio selection problem the decision maker considers simultaneously conflicting objectives such as ra...

Identification and selection of Six Sigma projects are one of the most frequently discussed issues in the Six Sigma literatures today. In this paper a two-stage methodology has been proposed based on (i) Real Option Analysis for evaluating the value of the project to improve the managerial flexibility (ii) a zero–one integer linear programming model for selecting and scheduling an optimal proje...

Project portfolio selection problems are inherently complex problems with multiple and often conflicting objectives. Numerous analytical techniques ranging from simple weighted scoring to complex mathematical programming approaches have been proposed to solve these problems with precise data. However, the project data in real-world problems are often imprecise or ambiguous. We propose a fuzzy M...

projects execution is an important way to implement organizational strategies, especially in the project-based organizations. in such organizations, the decision-makers usually encounter a problem of the project portfolio selection. of course, regarding the decision-makers’ risk attitude, they tend to direct organizational resources toward projects with low threats and high opportunities. this ...

Public and private organizations continuously invest on projects. With a number of candidate projects bigger than those ones that can be funded, the organization faces the problem of selecting a portfolio of projects that maximizes the expected benefits. The selection is made on the evaluation of project groups and not on the evaluation of single projects. However, there is a factor that must b...
