Constraint
Encyclopedia
Constraint is an element factor or a subsystem that works as a bottleneck. It restricts an entity, project, or system (such as a manufacturing or decision making process) from achieving its potential (or higher level of output) with reference to its goal.

- Theory of ConstraintsTheory of ConstraintsThe theory of constraints adopts the common idiom "A chain is no stronger than its weakest link" as a new management paradigm. This means that processes, organizations, etc., are vulnerable because the weakest person or part can always damage or break them or at least adversely affect the...

A solution is therefore a vector of variables that satisfies all constraints.The techniques used in...
