Network programming theory application to project portfolio formation

Serbian Journal of Management, 2021
The paper deals with an application of the network (dichotomous) programming method for solving multi-extremal problems and discrete optimization problems. The concept of a generalized dual problem is introduced and a theorem on its convexity

Dynamic Project Interdependencies (PI) in Optimizing Project Portfolio Management (PPM)

International Journal of Technology, 2015
Many researchers assess the tools and techniques to optimize the project portfolio management. Most of those tools treat each project within a portfolio as an independent entity. Starting in 2010 onwards, many researchers considered the importance of Project Interdependencies (PI) in defining the Project Portfolio (PP); however, those researchers ...

Regularizing Portfolio Optimization [PDF]

, 2009
The optimization of large portfolios displays an inherent instability to estimation error. This poses a fundamental problem, because solutions that are not stable under sample fluctuations may look optimal for a given sample, but are, in effect, very far
