Distribution function of random variable

Step 1 According to the probability distribution function of random variables p j and Vmj, samples coi and (02i are generated from their own sample spaces fli and Q2 respectively, i= 1,2,.., N ... 

Usually, the demand is described with random variables under uncertain environment. When we describe the demand with variables, we need a great amount of empirical statistics to get the distribution function. However, these data might be hard to get in some cases. The fussy sets theory is then a commonly used and elfeclive method which can quantihably describe the uncertain demand. The membership function of fuzzy numbers can be determined by the decision-makers when using fuzzy numbers to describe the demand, which is much easier to determine the membership function than the determination of distribution functions of random variable. 

To solve this problem, let Fi(s) and F2(u) be the distribution functions of random variables S and U respectively. The first order condition for problem...
