  1. x1 , x2 , x3 ? 0
  2. 8x2 – x1 ? 0
  3. x1, x2, ? 0
  4. ei , xi ? 0 for all i = 1,...,4
  5. xi,j ? 0 (i=1,2,3)   (j=1,2,3,4)

Which of the above can be non-negativity constraints in a linear model?


I and II

III and IV

II, III and IV

I, II, IV and V

I, II, III, IV and V

Yanıt Açıklaması:

A linear expression appears below; the powers of its variables x and y are equal to one.

2x – 3y

A linear constraint requires a linear expression to be equal to a number, to be less/greater than or equal to a number.

x + y = 4

x – 3y ? 2

x ? y

The last expression stated above is called a non-negativity constraint, which requires the value x to be greater or equal to zero. A linear program either minimizes or maximizes a linear expression subject to defined linear constraints.

As also understood from the information given, the correct answer is E. All expressions in the options are non-negativity constraints.
