Selection of a project portfolio with limited resources is an important decision in both public and industrial organizations. Often these decisions are complicated by a high number of project proposals, considerations of multiple criteria and resources, project interactions, uncertain project outcomes and incomplete information about decision maker's (DM's) preferences. Moreover, opportunity co...

Investors use different approaches to select optimal portfolio. so, Optimal investment choices according to return can be interpreted in different models. The traditional approach to allocate portfolio selection called a mean - variance explains. Another approach is Markov chain. Markov chain is a random process without memory. This means that the conditional probability distribution of the nex...

One central and important requirement for IS project portfolio selection is the adequate consideration of project interactions. However, the IS discipline notably lacks a common understanding of the nature of project interactions and their impact on IS project portfolio selection. To remedy this we conduct a systematic and interdisciplinary literature review thereby providing a starting point f...

491 Abstract— In this paper, we offer a new strategic portfolio model for national IT R&D project selection in Korea. A risk and return (R-R) portfolio model was developed using an objectively quantified index on the two axes of risk and return, in order to select a strategic project and allocate resources in compliance with a national IT R&D strategy. We strategize using the R-R portfolio mode...

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...

Adequately considering interactions among IT/IS projects in the process of constructing an IT/IS project portfolio is an important requirement for value-based IT/IS project portfolio selection. A lot of articles already deal with modeling approaches to incorporate such interactions, but the literature lacks a common terminology and a structured perspective on the manifold types of interactions ...

a vast number of organizational projects as well as complexity of decision making process can cause particular challenges for project management and its leadership. in order to use organization assets and opportunities efficiently, it is necessary that manager implement a comprehensive multidimensional project portfolio management system that considers economic, social and technical details of ...
