This first iteration leaves a supply of 20

**remaining**in row 1 , so next select X1,1 + 1 = X12 to be a basic variable . Because this supply is no larger than the demand of 20 in column 2 , all of it is allocated , X12 = 20 , and this row ...Page 371

At each iteration , after the difference for every row and column

**remaining**under consideration is calculated and displayed , the largest difference is circled and the smallest unit cost in its row or column is enclosed in a box .### What people are saying - Write a review
