tailieunhanh - Project portfolio selection problem with exponential synergistic effects

In this paper, an exponential function is considered for synergistic impact of the projects that make the problem more similar to the real-world problems. An illustrative example is used to demonstrate the appropriate application of the proposed model. | Project portfolio selection problem with exponential synergistic effects Journal of Project Management 4 2019 241 248 Contents lists available at GrowingScience Journal of Project Management homepage Project portfolio selection problem with exponential synergistic effects Mohammadamin Hemmatizadeha and Emran Mohammadia a Faculty of Industrial Engineering Iran University of Science amp Technology Tehran Iran CHRONICLE ABSTRACT Article history Project portfolio selection is a major issue in organizations which involves a complex pro- Received October 28 2018 cess from the first step to the end step of project selection.

Introduction A project is a complex effort and a project has to be completed in less than three years. Accom- plishment of any project is involved various tasks by different organizations Archer amp Ghasemzadeh 1999 . The portfolio is a collection of projects that either simultaneously or consist- ently must be considered during a
