Dozens of these around -- most well-known is COCOMO. Assumes software requirements relatively stable and project will be well managed. Basic COCOMO uses estimated size of project (primarily in terms of estimated lines of code) and type of project (organic, semi-detached, or embedded). Effort = A * KDSI b where A and b are constants that vary with type of project. More advanced versions add a series of multipliers for other factors: product attributes (reliability, database size, complexity) computer attributes (timing and storage constraints, volatility) personnel attributes (experience, capability) project attributes (use of tools, development schedule) and allow considering system as made up of non-homogeneous subsystems. ���
