The feasibility also can be seen from the high ARR value approximately between 15.4% and 29.4%. ARR is the
comparison between average annually profit and investment value, higher ARR value show higher average annually
profit when it is compared with the investment value, that further more imply the higher economic acceptance. To
analyze the rank of the economic feasibility of each case clearly, the value of each economic parameter is then
presented in Fig. 2.
