Applying interior points methods for the radiotherapyplanning problem in a fuzzy approach background

Jackeline del Carmen Huaccha Neyra, Aurelio Ribeiro Leite de Oliveira


Radiation Therapy Design Problem consists in minimize the total radiation dosageat the patient. In this work, the dosage values are represented by fuzzy numbers. The transitionfrom healthy tissue to tumour cells is continuous and the surprise function is adopted to model it.We propose to solve this problem by a specially tailored Primal-Dual Interior Point Method andpresent numerical experiments with real world large-scale problems.
