Abstract

A previously developed Fuzzy Waste Load Allocation Model(FWLAM) for a river system is extended to address uncertainty involved in fixing the membership functions for the fuzzy goals of the Pollution Control Agency (PCA) and dischargers. Decision-maker gets a range of optimal solutions as a stable interval on which some post-optimality analyses can be performed to fix the fractional removal levels of the pollutants, considering necessity of the water quality management issues. The present model maximizes the width of interval valued fractional removal levels for increasing flexibility of the decision-maker and minimizes width of the interval valued performance measure level for reducing the system uncertainty. The improvement of usefulness of optimal solutions over the previously developed Grey Fuzzy Waste Load Allocation Model (GFWLAM) is shown through the application on a hypothetical river system.
