Abstract
|
Kidney Dialysis is considered as one of the world’s major
health problems. Level of occurrence of this illness is high and every
year increases by %8. Kidney Dialysis refers to temporary or permanent
kidney damage which causes lack of proper functioning of kidneys. One
of the dangerous problems for Dialysis patients is blood pressure. On the
other hand life expectancy of these patients is matter of concern. Therefore finding a mathematical model which can link these two factors is of
great importance. In this research it has been assumed that input outputs
of the under evaluation units adhere to Rayleigh distribution. By considering suitable models for data envelopment analysis such as FDH, new
methods for determining random value of under evaluation units are presented. Since one of the main Rayleigh distribution functions is about life
expectancy, therefore the model is expanded to cover the dialysis patient’s
life expectancy.
