WebJun 18, 2024 · Big M Formulation. The big M method is a trick to switch on and off constraints. For example, constraint 1 above states that a case must start after the session start time. This is only valid for the session that the case is assigned to. ... Linear programming is a powerful tool for helping organisations make informed decisions … WebJul 21, 2024 · Linearity is the property of a mathematical equation in which the expressions among the variables are linear i.e. higher power of the variables and their products are not allowed. Thus, the function f of n variables x = (x1, . . . ,xn) is linear if there are constants a1, . . . , an such that: f (x) = a1 x1 + a2 x2 . . . + an xn
