Supplying safe water in Bangladesh: A policy model based on multi-objective mixed integer programming

At present, about 80 million people in Bangladesh are at risk of losing their health and having a sharply reduced life expectancy as a result of exposure to excessive arsenic through drinking water from tube wells. In this article, we build a multi-objective mixed-integer optimisation model, which we can simulate. We identify efficient loci of the trade-off between the several competing objectives in order to provide safe water to the affected people. Three types of simulation cases are discussed. For each case, a different type of safe water was chosen as optimal. Copyright (c) 2007 the author(s). Journal compilation (c) 2007 RSAI.
