1706 Views Hello,
I’m trying to do policy packaging for transport sector for cars only. I understand that the ‘inheritance’ concept means that LEAP fills in the gaps using data available in the selected scenarios based on their order. What if I want to ‘combine’ the numbers and not just take the first one available? For example, I have the cost for scenario 1, 2 and 3, how can get the total cost for implementing the three policy measures together?
Another case, I have the fuel economy figures for hybrid cars scenario, CNG cars scenario, and fuel economy standards scenario, how can I get the total energy demand when implementing the three policies?
Thanks!

1705 Views Hi Maha,
The first of your two scenarios should not overlap (since hybrid cars and CNG cars are two different policy measures that would affect different kinds of demand technologies). If your Fuel Economy scenario affects the fuel economies of both hybrid and CNG transport, then it should inherit from both of those (non-overlapping) scenarios. A complete mitigation scenario may then inherit from the Fuel Economy scenario, and others as necessary, which may themselves be packages of other scenarios.
Have a look through our online example of scenario inheritance that is similar to your situation:

Hope this helps,

1695 Views Thank you Taylor, I was wrong, sorry! What I meant is to combine hybrids (or) CNG cars, and fuel economy standards.
Actually I have one more scenario and that is annual registration fees (known as VED in some countries). What I intend to do is to combine the new registration fees system (which affects the number of new cars); the fuel economy standards (that assume a certain number for the fuel economy); and the hybrids (that assume the penetration of a given number of hybrids which again have different fuel economy).
My question is how to consider these different fuel economy (and / or) new cars figures using the policy packages? And what about getting the total cost for implementing all of the three options?
Thanks.

1692 Views Hi Maha,
There should be no problem combining your three scenarios (let's call them scenario A, B and C) into one, by allowing the fourth scenario to inherit from the other three. In this case your expression search order for the fourth scenario might look like this:
C, B, A, CA (CA stands for 'Current Accounts')
As long as none of your scenarios logically interfere or overlap with one another (i.e. as long as you have entered scenario data only for different variables in each different scenario), the fourth scenario will inherit all of the data you've entered into the other scenarios. An example of a 'logical conflict' would be scenario A imposing fuel economy X, while scenario B imposes fuel economy Y. In this event, it does not make sense to try to implement both at once.
Hope this helps,
Taylor

1682 Views Thanks, it worked for me. But it looks that I have a problem with the cost.
Let's say that I have three scenarios (A, B & C) and the cost for all of them is entered in the Demand cost tab (as Total cost of the cost method). I'm wondering if I can use some function to get the sum instead of doing it manually through the Excel.
Thanks.

1680 Views Hi Maha,
So there are some measures in different scenarios that overlap with one another, if you create a scenario that inherits from each of them?
In that case, you could use the ScenarioValue() function in your Demand Cost, like this:
Scenariovalue(A) + Scenariovalue(B)+ ...

You might also want to read about the ParentScenariovalue() functions:

Good luck,
Taylor
