Since the 1950s, a substantial body of scholarship on cost uncertainty analysis has evolved. Published material appears in numerous industry and government technical reports, symposia proceedings, and professional journals. Despite this, there is a need in the systems engineering community to synthesize prior scholarship and relate it to advances in technique and problem sophistication. Created to address this need, this book is designed as a reference for mathematically-literate systems engineers, engineering managers, cost engineers, systems cost and economic analysts, management scientists, and operations research analysts.
