Perfect Foresight vs. Time-Stepped Approach kramea Kalai Ramea Posts: 9 Threads: 2 Joined: Jan 2014 06-07-2015, 04:48 PM Hi Antti,Just to follow up on the user constraint, here is the formulation I need to implement:NCAP_ITAX(t) = function(VAR_NCAP(t-1))The 'function' I have is a non-linear one, but let's assume that I can approximate to a linear one.The user constraint can be translated to,NCAP_ITAX(t) - function(VAR_NCAP(t-1)) <= 0I have two questions here:a) Is there a way to generalize this equation for all the timeperiods? I have so far explicitly specified the model constraints and values for each year/timeperiod based on back-end calculations. I will not know the NCAP values for the timeperiods prior to running, so it makes sense to generalize the equation.b) I need to calculate the NCAP_ITAX dynamically with previous year's VAR_NCAP values. How can I include a function that takes NCAP values to arrive at new ITAX values?As you can see, this is becoming similar to ETL problem. Is there a simple way to implement this? « Next Oldest | Next Newest »
