This report focuses upon identifying and characterizing a number of factors that contribute to the uncertainty associated with performance of various vehicle exhaust emission control programs (EECPs). These programs include inspection/maintenance procedures, retrofit, fuel modificaiton schemes, and I/M-retrofit combinations. The methodolgy for evaluating I/M programs consists of a computer simulation of the basic process over time. Experimental data on individual retrofit devices were statistically analyzed and fuel modification procedures were reviewed using engineering cost estimates. Finally, optimal (least cost) I/M-retrofit combinations are determined using two alternative integer programming formulations. 1.0 Conclustions -- 2.0 Recommendations -- 3.0 Introduction -- 4.0 Methodolgical approach -- 5.0 Inspection/maintenance programs -- 6.0 Retrofit programs -- 7.0 Combination of retrofit and I/M programs -- 8.0 Fuel modification programs. |
