• Lattice model (finance), a "discrete-time" model of the varying price over time of the underlying financial instrument, during the life of the instrument.
• Lattice model (mathematics), a regular tiling of a space by a primitive cell.
• Lattice model (biophysics), a class of Ising-type models for the description of biomacromolecules, their transformations and binding in gene regulation and signal transduction.
• Lattice-based access control (Computer security) - a complex access control model based on the interaction between any combination of objects and subjects.
