A '''mathematical model''' uses [[mathematics|mathematical]] language to describe a system. Mathematical models are used not only in the [[natural science]]s and engineering disciplines (such as [[physics]], [[biology]], [[earth science]], [[meteorology]], and electrical engineering) but also in the [[social science]]s (such as [[economics]], [[psychology]], [[sociology]] and [[political science]]); [[physicist]]s, [[engineer]]s, [[computer science|computer scientist]]s, and [[economist]]s use mathematical models most extensively.

Eykhoff (1974) defined a ''mathematical model'' as 'a representation of the essential aspects of an existing system (or a system to be constructed) which presents [[knowledge]] of that system in usable form'.
