Summer — tourism traveling: in summer — tourism 
traveling status considering the high importance of 
sightseeing attractions criterion (F2), this criterion is 
granted the highest value in the model (formula 4), 
also another important case in tourism traveling is the 
extent of traffic in the roads so considering this case

the next highest value is granted to traffic criterion 
(F3). In order to investigate the accuracy of granted 
values to different criteria and testing this issue that 
what would happen if one or more of criteria will be 
excluded from the model we will work it out in 
sensitivity analysis section.

traveling respectively. Also note that Fl is the 
criterion of weather condition, F2 shows the 
sightseeing attraction, F3 is the criterion of traffic, F4 
stands for safety and F5 is the criterion of facilities, Li 
is the length of every part of the route. The F1 to F5 
parameters are not constant but they are functions of 
their specific sub criteria which will be reviewed in 
next sections 
Summer — none tourism traveling: in this kind of 
traveling since the sightseeing attractions have the 
least importance for the travelers the granted value 
two this criterion is 0. And since the traffic rate is very 
important for the traveler in this kind of traveling and 
he wants to get to the destination as soon as possible 
this criterion (F3) is the most important criteria in this 
specific model.
