1) Note that the problem requires to make "on", "off" decisions that can be modeled using binary decision variables. Formulate an Integer Program model for this prob- lem. Clearly state the decision variables, objective, and constraints in your formulation. 2. Create an AMPL model and data file for this problem and solve it. Provide a print- out of your model file, data file, solution 3. What is the optimal solution recommended by AMPL? 4. Reconsider the linear programming formulation for your problem. Propose either a new objective, and/or a new constraint (s) for the problem that would take into account some realistic feature of the problem not considered above (e.g., ramping costs, selling of surplus load). Come up with some sensible values for the parameters required to implement such additions to the problem and: (a Provide the new Integer Programming formulation of the problem (b) Discuss how the optimal solution of the problem changes after taking into account the new Integer Programming formulation 5. Write an "large-scale" Integer Programming formulation for this problem in which the number of days in which the company has to satisfy demand for electricity goes in general from 1, ..., T (i.e., the company would like to be able to solve the problem for any desired number of days ahead). Create appropriate names for the parameters that would be needed to formulate such problem. Clearly state the parameters, decision variables, objective, and constraints in your formulation.
