In optimization models, the formula for the objective function cell directly references decision variables cells. In complicated cases there may be intermediate calculations, and the logical relation between objective function and decision variables be indirect.

It is a process by which a linear function of several variables, called the objective function, is maximised or minimised when it is subject to one or more linear constraints in the same variables.
A function.
A function relationship between two or more variables, inputs and outputs, where each and every value input has a uniqueoutput.
It is a programming problem in which the objective function is to be optimised subject to a set of constraints. At least one of the constraints or the objective functions must be non-linear in at least one of the variables.
Linear programming can be used to solve problems requiring the optimisation (maximum or minimum) of a linear objective function when the variables are subject to a linear constraints.
