This paper investigates the problem of selecting and scheduling a set of projects among available projects. Each project consists of several tasks and to perform each one some resource is required. The objective is to maximize total benefit. The paper constructs a mathematical formulation in form of mixed integer linear programming model. Three effective metaheuristics in form of the imperialis...

This paper deals with multi-period project portfolio selection problem. In this problem, the available budget is invested on the best portfolio of projects in each period such that the net profit is maximized. We also consider more realistic assumptions to cover wider range of applications than those reported in previous studies. A novel mathematical model is presented to solve the problem, con...

Due to technological enhancements, traditional, qualitative decision-making methods are usually replaced by data-driven even in smaller companies. Process simulation is one of these solutions, which can help companies avoid costly failures as well evaluate positive or negative effects. The reason for this paper twofold: first, authors conducted a Quality Function Deployment analysis find the mo...

risk management is one of the most important aspects of project management that identifies, assesses and responds to project risks. although many papers have been published in project risk response, presented tools and methods are poor. hence, in this paper, we present an optimization model to respond project risk that seeks to optimize two key criteria of project: cost and time. the proposed m...

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...
