Fig. 3: Parallel coordinate plot showing the performance of different infrastructure partnerships relative to four decision-relevant objectives (vertical axes).

Each colored line represents one of the 374 optimal tradeoff partnerships. The location where a partnership intersects each vertical axis represents its performance with respect to that objective. Each objective is oriented such that the preferred direction is up (e.g., maximum water gain, minimum cost). Thus, ideal performance would be a horizontal line across the top, while diagonal segments represent tradeoffs between conflicting objectives.
