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:
