- 1 Excluded variables
- 2 We need to take account of that the emissions variable is per year and the concenctration variable is in 2020
- 3 Bus technology variable is "current" and the assessment has its scenarios in 2020.
- 4 Add "total concentration" as supplementary data to the diagram. ("constant node" in Analytica)
Excluded variables
Statements: The following variables should not be included in the assessment
Resolution: Accepted. (A stable resolution, when found, should be updated to the main page.) |
| Argumentation:
←1: For A, B, C: We are not interested in non-bus-derived emissions. --Jouni 23:11, 18 February 2008 (EET) |

Bus technology variable is "current" and the assessment has its scenarios in 2020.
| Statements: Bus technology variable is "current" and the assessment has its scenarios in 2020.
Resolution: Resolution not yet found. (A stable resolution, when found, should be updated to the main page.) |
| Argumentation:
