Controlling the chemo-derug dose using a Mamdani fuzzy system
The upper limit of the chemo-drug dose is limited based on the oncologists’ recommendations. Several factors affect on the oncologists’ decision for choosing a desire chemo-drug dose such as age and gender of the patient, current diseases or other special cases such as pregnancy. For a young patient, it is possible to prescribe a more dose than an elderly one because of more ability of the body of a young patient to rebuild healthy/immune cells. While, an older patient should be offered a lower dose since his/her body does not have the ability to regenerate healthy/immune cells as well as young ones; therefore, the treatment strategy should be able to maintain healthy/immune cells in his/her body as much as possible. In this paper, a Mamdani fuzzy system is designed to limit the upper bound of the chemo-drug dose by considering the age of the patient.
A fuzzy system including N rules can be given in the following form:
