S14.6. A small metal-parts shop contains three machines-a drill press, a lathe, and a grinder-and has three operators, each certified to work on all three machines. However, each operator performs better on some machines than on others. The shop has contracted to do a big job that requires all three machines. The times required by the various operators to perform the required operations on each machine are summarized as follows: The shop manager wants to assign one operator to each machine so that the total operating time for all three operators is minimized. Formulate and solve a linear programming model for this
