Ethical Perspective: Five Unacceptable Trade-offs on the Path to Universal Health Coverage

This article discusses what ethicists have called “unacceptable trade-offs” in health policy choices related to universal health coverage (UHC). Since the fiscal space is constrained, trade-offs need to be made. But some trade-offs are unacceptable on the path to universal coverage. Unacceptable choices include, among other examples from low-income countries, to expand coverage for services wit...

Evolving Engineering Design Trade-offs

In the engineering design process, it is important to know the engineering trade-offs achievable under various design preferences and strategies. In this paper, a family of engineering design trade-offs are evolved from an automatic design synthesis methodology based on evolutionary computation. The complete Pareto optima frontier can be evolved by a consideration of fitness function that aggre...

Compensation and Weights for Trade-offs in Engineering Design: Beyond the Weighted Sum

Multicriteria decision support methods are common in engineering design. These methods typically rely on a summation of weighted attributes to accomplish trade-offs among competing objectives. It has long been known that a weighted sum, when used for multicriteria optimization, may fail to locate all points on a nonconvex Pareto frontier. More recent results from the optimization literature rel...

Defining Pathways and Trade-offs Toward Universal Health Coverage; Comment on “Ethical Perspective: Five Unacceptable Trade-offs on the Path to Universal Health Coverage”

The World Health Organization’s (WHO’s) World Health Report 2010, “Health systems financing, the path to universal coverage,” promoted universal health coverage (UHC) as an aspirational objective for country health systems. Yet, in addition to the dimensions of services and coverage, distribution of coverage in the population, and financial risk protection highlighted by the report, the conside...
