The linear programming problem of 1. 1 and the proposition of the mathematical model of 1. 1 (I)
1. 1. 1 (2)
1. 1. 1 (3)
The above two cases have some * * * characteristics:
The (1) scheme is represented by a set of variables. Usually, the values of these variables are negative.
⑵ There are certain constraints, which can be expressed by linear equality or linear inequality.
(3) Everyone has a goal to achieve, which can be expressed by a linear function of a decision variable.
