Many hospital managers face a lack of information about the capacity of the dialysis complex and the uncertainty of the impact of adding new methods for eva‎luation. If the allowable capacity to serve exceeds the maximum standard capacity expected, patient satisfaction will decrease due to increased waiting time, physicians and nurses' ability to physically and mentally decline, and hospital costs will increase. Given this importance, this study with the aim of minimizing scheduling, maximizing the use of dialysis centers and its proper in five chapters use, minimize the idle time of physicians and nurses provides a model to achieve the ultimate goal of the hospital is to care for the largest number of patients while maintaining Be the highest standard of care and patient satisfaction. On the other hand, due to the many uncertainties in the treatment processes, the mathematical model of this problem has probably been done. According to the case study of the mathematical model in Mazandaran Dialysis Center, first the mathematical model was validated and finally, due to the multi-objective nature of the mathematical model, the constraint was resolved using the Epsilon method. The optimal solutions obtained after solving the model for the first objective function , which minimize the total amount of dialysis time for a 24 - hour period and the second objective function is to minimize the dialysis costs of each patient, are 19.6 and 3030.
