The table operation method is also called the minimum element method. It is to find out the smallest element in the freight rate table, and then fill in the corresponding box in the freight rate table with the maximum allowable value. If the output or sales volume of a certain row or column has been met, the row or column in the freight rate table will be crossed out. Find out the minimum value in the uncrossed freight rate, and proceed in sequence according to this method. The direct table operation method is a simple and effective method to solve the transportation problem. The solution process is carried out on the transportation table. This is an iterative solution method. The iterative steps are as follows:Step 1: Find a feasible solution of initial basis according to certain rules.Step 2: Make the most judgment on the solution, that is, find the test number of non-base variables to judge whether the optimal solution is reached. If it is already the optimal solution, stop the calculation; If it is not the optimal solution, proceed to the next step.Step 3: Improve the initial scheme on the table to find out the new basic feasible solution, and then judge according to step 2 until the optimal solution is found. The table operation method is specifically solved as follows:
