Effective management of project activities is a critical issue for project managers, especially when the projects are complex. This is more essential for projects where the number of activity attributes is numerous. In such circumstances, prioritizing of project activities is an important issue and can enable better management of projects by focusing more on the most critical activities. However, in many cases prioritizing project activities can be a difficult task because some of the activity attributes might not be expressed easily in crisp terms. In this article, a practical fuzzy rating and ranking approach is proposed to prioritize project activities with fuzzy attributes. The proposed approach is also tested through an example problem from the literature.
