Informing decision-making in single-objective, mixed-variable design problems
Data-driven decision-making in mixed-variable design problems presents a variety of challenges and opportunities, especially in the increasingly data-rich field of emissions in architectural and structural design. Designers can benefit from an underlying knowledge about, for example, whether …

Estimating Costs of Reducing Environmental Emissions From a Dairy Farm: Multi-objective epsilon-constraint Optimization Versus Single Objective Constrained Optimization
… air can harm water quality. We conduct a multi-objective optimization analysis for a representative dairy farm with two different approaches: nonlinear programming (NLP) and ϵ-constraint optimization to evaluate trade-offs among reduction of multiple pollutants including nitrogen (N), phosphorus …

What attitudes about opium were driving the government of India's policies between 1857-1906?
… this analysis will show is that there was no single objective or agenda that was driving British opium policy or ideas about the drug. Policies on opium operated at different levels and similarly they did not always relate to one another. They were affected by multiple ideas, local politics …
