1.020 Ecology II: Engineering for Sustainability Lectures 08_20 Multiple Objectives, Pareto Optimality Motivation/Objective Develop a way to compare values of different resource uses. Consider tradeoff between using limited water for farm revenue vs. using water for preservation of the riparian ecosystem. Approach 1. Introduce a riparian ecological abundance measure as a second objective in the resource allocation problem of Lectures 8_16 and 08_17. This simplified measure assumes abundance is a linear function of the flow downstream of the irrigation diversion. We would like to maximize both revenue and abundance but these objectives conflict. 2. Include abundance objective as a constraint in the resource allocation problem and use MATLAB to evaluate the tradeoff between revenue and diversity.
