Subject: Annual Activity level and Monthly Variation Posted: 1/7/2014 Viewed: 21548 times
Hi All. I have a demand site (a branch) with time horizon ( 1962-2020) ,
1: from 1962-2010 with the same Monthly Variation
2: from 2011-2020 with a different Monthly Variation.
when i input all data above ( with horizon 1962-2020).WEAP can not run with whole time from 1962-2020. However when i divide time horizon into two periods ( 1962- 2010 and 2011-2020), Weap can run with each period.
my question: how to run with the whole time horizon 1962-2020 with different Monthly Variation for each period? please help me.
Mr. Jack Sieber
