Interchangeability can refer to:
*
Interchangeable parts, the ability to select components for assembly at random and fit them together within proper tolerances
*
Interchangeability (computer science)
In computer science, an interchangeability algorithm is a technique used to more efficiently solve constraint satisfaction problems (CSP). A CSP is a mathematical problem in which objects, represented by variables, are subject to constraints on th ...
