Optimal Treatment Levels of a Stream Pollution Abatement System Under Three Environmental Control Policies. Part II. Preliminary Sensitivity Analysis of a Convex Equivalent of the Fixed Dissolved Oxygen Requirement Policy GP Model Using Sensumt.

The sensitivity is analyzed of the optimal waste treatment cost of a water pollution control model, with respect to the parameters involved in the formulation of the model. This analysis is conducted for the policy mandating a fixed dissolved oxygen requirement, using an upper Hudson River data base. Details concerning the formulation and solution of this problem were reported in another paper. It is shown here that the maximum allowable dissolved oxygen deficit is unequivocally the parameter to which the optimal waste treatment cost is most sensitive. All of the many parameters involved in the model are analyzed and, relative to stipulated assumptions, are shown to have from significant to negligible impact on the waste treatment cost. (Author)
