Application of fuzzy time series to population forecasting

Dear employer, I read carefully your requirements and the pdf file attached about fuzzy time series. What you want exactly is to know : 1) How to get table 1 in the third page ? 2) How to define the fuzzy set in equation 3 in the fourth page ? 3) How the population forcasting of year 1990 was calculated ? You may rest assured dear employer, I will explain all the previous questions until you have full grasp of your inquiry. Please send me a message anytime you are ready.
