IEE 367 Lab 10 Code the .mod and .dat files in AMPL. Solve this initial problem and report the optimal solution and optimal objective function value. Model, code, and solve the following variant to this network problem. Suppose there is a failure in one of the production lines leading to the reduction in capacity to 400K Personal Computers. Now, you will not be able to satisfy the demand of all your customers. There is a cost per unit for not satisfying the demand of your customer, as found in the table below. Formulate and code this new variant to minimize the total cost. Indicate which cities have unsatisfied demand
