Consider the following table for four different sources of energy: Resource, minimize Natural Gas Coal Wind Solar $25 0.5 Min.fi, cost ($/million BTU) Min. 12. environmental impact Max. s. availability/accessibility Max. f4, renewability of energy $30 0.8 0.85 $35 0.3 0.60 $65 0.2 0.45 0.9 0.8 0.8 (a) Consider the bicriteria problem of cost versus environmental impact and graphi- cally show if any of the given four sources are inefficient. Suppose that the weights of importance for the bicriteria problem of cost versus environmental impact are (0.7.0.3), respectively. Rank all alternatives. (b) Consider the four-criteria problem and identify if any of these resources are inefficient. Suppose that the weights of importance for the four-criteria problem are (0.4.0.2, 0.2,0.2), respectively. Rank all alternatives.
