Healthcare Systems Engineering

AN AUTHORITATIVE INDUSTRIAL ENGINEERING APPROACH TO HEALTHCARE SYSTEMS OPTIMIZATION

Healthcare Systems Engineering offers comprehensive coverage of engineered solutions to healthcare delivery, measurement, and modeling. Thoughtful discussion tackles both domain and relevant statistical and quantitative models to improve current systems or design new ones from the ground up. Examples and case studies illustrate the practical aspect of the presented strategies to help readers from a variety of backgrounds quickly apply new approaches in practice.

Identify the components, stakeholders, and major drivers of the healthcare delivery system View healthcare as a complex adaptive system to apply systems thinking and system dynamics methodologies Optimize financials with models for compensation, cost allocation, and capital budgeting Manage healthcare data and find data mining and visualization solutions Dig into logistics and supply chain with solid approaches to demand, inventory control, distribution, coordination, and more

With practical insight and clear, authoritative discussion, Healthcare Systems Engineering provides much–needed guidance for this emerging, interdisciplinary field.
