An optimization problem seeks to minimize a loss function.
Function cost analysis
Function value analysis
Function cost analysis (FСА) (sometimes called function value analysis (FVA)) is a method of technical and economic research of the systems for purpose to optimize a parity between system's (as product or service) consumer functions or properties (also known as value) and expenses to achieve those functions or properties.
