Compatibility of systems of linear constraints over the set of natural numbers.
Criteria of compatibility of a system of linear Diophantine equations, strict inequations,
and nonstrict inequations are considered. Upper bounds for components of a minimal set of solutions
and algorithms of construction of minimal generating sets of solutions for all types of systems are given.
