According to the clinical practice, in the Intensity modulated radiation therapy (IMRT) procedure some of the parameters are fuzzy. In this paper, the optimal treatment has been shown as a solution of an optimization problem with quadratic objective function, where the prescribed target dose is a trapezoidal fuzzy number. We in [5] solved this problem with prescribed target dose in the form of triangular fuzzy number. Since the solution set is non-convex, the optimal solution has been obtained by relaxation method. Numerical simulationis given in head-and-neck cancer.
