Graphical and Simplex Methods of Linear Programming The graphical method is the more popular method to use because they are easy to use and understand. Working with only a few variables at a time they allow operations managers to compare projected demand to existing capacity. The graphical method is a trial and error approach that can be easily done by a manager or even a clerical staff. Since it is trial and error though‚ it does not necessarily generate the optimal plan. One downside of this method

the order of the matrix is 3 × 4. (ii) Since the order of the matrix is 3 × 4‚ there are 3 × 4 = 12 elements in it. (iii) a13 = 19‚ a21 = 35‚ a33 = −5‚ a24 = 12‚ a23 = Question 2: If a matrix has 24 elements‚ what are the possible order it can have? What‚ if it has 13 elements? Answer We know that if a matrix is of the order m × n‚ it has mn elements. Thus‚ to find all the possible orders of a matrix having 24 elements‚ we have to find all the ordered pairs of natural numbers whose product
