Abstract

A fundamental requirement for pollution control is to quantify the emissions being released through emission values. This report expanded the research of Nagurney (2000) by calculating the coefficient of PM₁₀ (Particulate Matter < 10 micrometers) and incorporating that into both single and multi-period case studies. Sensitivity analysis was done on reducing the emission constraint and noting the changes to the cost for each path. Several observations were made: (1) single and multi-period scenarios of the same case study followed similar patterns with the addition of emission and further reduction of the emission constraint; (2) for fixed demand, separate cost and variable demand, un-separate cost the cheapest 

path remained the same despite the addition of emission; (3) for variable demand with separate cost scenario there existed two economical paths at 15% emission reduction; (4) emission reductions of > 5% did not affect the optimal path for fixed demand with separate cost systems.
