In this research work, fuzzy mathematical model using
generalized gamma distribution, a mathematical model based on fuzzy
log-logistic distribution, a fuzzy Rayleigh distributionmathematical model,
fuzzy reliability model by means of generalized Rayleigh distribution, fuzzy
mathematical model using Nadarajah and Haghighi distribution, fuzzy survival
analysis model using exponentiated Nadarajah
distribution were developed. The thesis
planned to cover six chapters as follows:
one, Literature review, mathematical models established
using fuzzy methods and the particulars about the hormone Oxytocin has been
chapter two, a mathematical model developed by using fuzzy
generalized gamma distribution (FGGD) and fuzzy log-logistic distribution
(FLLD) and it is used to calculate the effect of different doses of oxytocin
has been conversed. The fuzzy mean and variance values are calculated for the changes of
hind paw with drawl latency (HWL) of normal
mature mice for dissimilar doses oxytocin 103 was analysed.
Chapter three, fuzzy Rayleigh distribution (FRD) model and Fuzzy
generalaized Rayleigh distribution (FGRD) model has been debated. The parameter of Rayleigh distribution model
was find out by using maximum likelihood estrimator. The mean and variance
values are calculated for the salivary excretion of oxytocin 92 after
intransal administration of oxytocin. Using FGRD model the
haemodynamic effects 76 of oxytocin 5u was calculated by finding
the mean and variance of FGRD.
In chapter four, the fuzzy models based on FGGD,
FLLD, FGRD and FRD were used to find the haemodynamic changes caused by
oxytocin by finding the mean and variance values. The most reliable fuzzy model
among the above mentioned model was find out by using the testing of hypothesis
for the mean values of repiratory changes, heart rate, cardiac output, stroke
volume after administration 5u and 10udoses of oxytocin.
In chapter five, fuzzy reliability model was
established using generaliaed Rayleigh distribution (FGRD) and Fuzzy Nadarajah
and Haghighi (FNH) distribution. Theses models were using to measure the
reliablity or survival values and hazard rate values for the different time
interval after the administratrion of oxytocin for womens, undergoing caesarean
section 90, 100 were established.
In chapter six, Fuzzy Exponentiated
Nadarajah and Haghighi (FENH) distribution model was established. The survival
and hazard rates were measured for different time interval after the
administratrion of oxytocin for lower alpha cut
and for the upper alpha cut regarding the time intervals.
