This paper proposes two methods for medical facitity programming to evaluate a medical treatment function with its patient data, in order to determin the function and size of the medical facility/hospital. One method is based on the length of patients' stay and the medical treatment fee. The other is the method to analyze the competitive ability of that hospital, that is, with its regional demand of health and the number of patients to treat there in classification of diseases. We quote the PPM (Product Portfolio Management) which is a marketing technique, and analyzes market growth rate arround the hospital and its share. To confirm the validity of these methods that we propose, we applied these methods to “A” hospital (103beds). Then we learn that these analysis methods make clear the treatment function of “A” hospital (Originality, strength and weakness etc.).
