Abstract. In this paper we propose a new method for the solution of project scheduling problems under fuzzy environment. The duration of all fuzzy activities are represented as trapezoidal fuzzy numbers. We compute several project characters such as earliest times, latest times, slack times and various floats for each fuzzy activity in the project scheduling problems. Numerical examples are provided to illustrate the efficiency of the proposed method.
